Aristotle, in the Rhetoric, appears to claim both that emotion-arousal has no place in the essential core of rhetorical expertise and that it has an extremely important place as one of three technical kinds of proof. This paper offers an account of how this apparent contradiction can be resolved. The resolution stems from a new understanding of what Rhetoric I.1 refers to - not emotions, but set-piece rhetorical devices aimed at manipulating emotions, which do not depend on the facts (...) of the case in which they are deployed. This understanding is supported by showing how it fits with evidence for how rhetoric was actually taught in the fifth and fourth centuries BCE, in particular by rasymachus and Gorgias. The proposed interpretation fits well with Aristotle's overall view of the nature of rhetoric, the structure of rhetorical speeches, and what is and is not relevant to the pragma, the issue of the case at hand.

The understanding of emergent, self-organizing phenomena has been immensely deepened in recent years on the basis of simulation-based theoretical research. We discuss these new ideas, and illustrate them using examples from several fields. Our discussion serves to introduce equivalent self-organized phenomena in social interaction. Interaction systems appear to be structured partly by virtue of such emergents. These appear under specific conditions: When cognitive buffering is inadequate relative to the levels of stress persons are subjected to, anxiety-spreading has the potential of (...) pushing their interaction into nonlinear conditions. Arousal in these conditions produces effects on behavior arising from biological sources-indeed, behavior can come under the control of reflex patterns. When this occurs, psychological activity no longer screens off biological controls over behavior. As the direct effects of biological activity spill into interaction, attachment behavior introduced into an interaction system can produce effects that are transmitted beyond dyads to produce global social patterns. These effects illustrate how strong interactions based in biological activity can produce an architecture for social systems. (shrink)

Nell restricts cruelty to hominids, although good evidence suggests that secondary aggression in rodents and particularly primates may be considered cruel. A considerable literature shows that glucocorticoid secretion stimulated by stress facilitates learning, memory, arousal, and aggressive behavior. Either secondary aggression (to a conspecific) or increased affiliative behavior reduces stressor-induced activity, suggesting the reward system can be satisfied by other behaviors than cruelty.

This commentary argues for the inclusion of the neurophysiological arousal concept to help understanding the brain mechanisms of emotions and reward and the cognitive mechanisms involved.

Background: Human sexual classical conditioning effects are less robust compared with those obtained in other animals. The artificiality of the laboratory environment and/or the unconditioned stimulus (US) used (e.g. watching erotic film clips as opposed to participating in sexual activity) may contribute to this discrepancy. The present experiment used a field study design to explore the conditioning of human sexual arousal. Method: Seven heterosexual couples were instructed to include a novel, neutrally preferred scent as the conditioned stimulus (CS+) during (...) sexual interaction and another novel scent during non-sexual coupledinteraction (e.g. watching a movie, studying together). Seven control couples used both scents during nonsexual interaction. Conducted over a 2-week period, both experimental and control couples had three sexual interactions (oral sex and/or intercourse). In addition, experimental couples had three, while the controls had six, non-sexual interactions. Genital responding to and affective preference for the odors were assessed in the laboratory before and after the experience in the men. Results: We observed significantly increased genital responding to the CS+in the experimental relative to the control group; however, conditioned responses were not much stronger than those obtained during laboratory conditioning. Experimental males also showed a trend for decreased preference for the CS-odor. They may have learned that this odor predicted that sexual interaction with their partner would not occur. Conclusion: The present study provides another demonstration of conditioned sexual arousal in men, specifically an instance of such learning that happened in a real-world setting. It also suggests that inhibitory learning may occur, at least with the affective measure.

This paper examines the causal basis of our ability to attribute emotions to music, developing and synthesizing the existing arousal, resemblance and persona theories of musical expressivity to do so. The principal claim is that music hijacks the simulation mechanism of the brain, a mechanism which has evolved to detect one's own and other people's emotions.

Theories of binding have recently come into the focus of the consciousness debate. In this review, we discuss the potential relevance of temporal binding mechanisms for sensory awareness. Specifically, we suggest that neural synchrony with a precision in the millisecond range may be crucial for conscious processing, and may be involved in arousal, perceptual integration, attentional selection and working memory. Recent evidence from both animal and human studies demonstrates that specific changes in neuronal synchrony occur during all of these (...) processes and that they are distinguished by the emergence of fast oscillations with frequencies in the gamma-range.

Merker offers a remarkable statement about the neural integration essential to conscious states provided by the mesodiencephalon. The model for triangular interaction between action selection, target selection, and emotion is heuristic. Unfortunately, there is little interest (relatively speaking) in neuroscience in the mesodiencephalon, and attention is currently heavily directed to the telencephalon. This suggests that there may be less real momentum than commonly assumed towards the Holy Grail of neuroscience, a scientific theory of mind, despite the major upsurge in interest. (...)

The neurophysiological phenomenon of LTP (long term potentiation) is considered by many to represent an adequate mechanism for acquiring or storing memories in the mammalian brain. In our target article, we reviewed the various arguments put forth in support of the LTP/memory hypothesis. We concluded that these arguments were inconsistent with the purported data base and proposed an alternative interpretation that we suggested was at least as compatible with the available data as the more widely held view. In doing so, (...) we attempted to illustrate that the inadequacy of present experimental designs did not permit us to distinguish between equally viable hypotheses. In the four years since we wrote the first draft of our target article, hundreds of additional studies on LTP have been published and their results have been incorporated into current theories about memory. A diverse group of commentators responded to our target article with their own theories of how memories might be stored in the brain, some of which rely on LTP. Some commentators doubted whether memories can be stored through modifications of synaptic strength. Some assert that it will never be possible to understand the neural mechanisms of memory; still others remain hopeful that we will accomplish some semblance of a resolution, provided we appreciate LTP's role in a subset of seemingly amorphous memory systems. In summary, although it is commonly written that “LTP is a memory storage device,” the divergence of views among the commentators suggests, at least as strongly as our target article, that such conviction is unwarranted and fails to acknowledge both the lack of consensus regarding the role of LTP in memory and the complexity of the phenomenon of memory itself.

Dreams of chase or pursuit, falling, sex, flying, nudity, failing an examination, one's own and other's death, fire, teeth falling out and some other themes experienced, even if only rarely, by many people all over the world have been labelled 'typical dreams'. This essay argues that typical dreaming, rather a syndrome of themes than monothematic, reflects an extraordinary state of mind and brain. Odd and particularly memorable perceptions, as well as emerging awareness of sleep and dreaming -- i.e. parallels to (...) lucid dreaming, sleep paralysis, complex partial seizure, epileptic and migraine auras, and aspects of dreaming after trauma -- can be traced with some plausibility in all prominent variants of typical dreaming. When viewed from this perspective, for example, dream pursuers are much more a shadow of the bodily self than a metaphor for the psycho- biographical situation or evolutionarily implemented sparring partners who make dreamers fit for the struggle for survival during waking hours.

Abstract: Each affective state has distinct motor-expressions, sensory perceptions, autonomic, and cognitive patterns. Panksepp (1998) proposed seven neural affective systems of which the SEEKING system, a generalized approach-seeking system, motivates organisms to pursue resources needed for survival. When an organism is presented with a novel stimulus, the dopamine (DA) in the nucleus accumbens septi (NAS) is released. The DA circuit outlines the generalized mesolimbic dopamine-centered SEEKING system and is especially responsive when there is an element of unpredictability in forthcoming rewards. (...) We propose that when the outcome of this interaction is unexpected or unanticipated then Panksepp’s “cognitive or expectancy reset” mechanism involving the cognitive dissonance would yield the subjective emotion of surprise. In order to appropriately react to the environment’s stimuli one needs fundamental processes that would enable one to distinguish between what is novel and what has been already experienced, as well as the different degrees of novelty. Novel events are those whose essential features of the representation (visceral and perceptual) are altered and being discrepant provoke more sustained attention. Novelty arises from salient and arousing events and the organism experiences surprise, as coming out of a habitual state. In this framework, we shall look at established theories of emotions and propose a different approach to their taxonomy. (shrink)

The author proposes a dimensional model of our emotion concepts that is intended to be largely independent of one’s theory of emotions and applicable to the different ways in which emotions are measured. He outlines some conditions for selecting the dimensions based on these motivations and general conceptual grounds. Given these conditions he then advances an 8-dimensional model that is shown to effectively differentiate emotion labels both within and across cultures, as well as more obscure expressive language. The 8 dimensions (...) are: (1) attracted—repulsed, (2) powerful—weak, (3) free—constrained, (4) certain—uncertain, (5) generalized—focused, (6) future directed—past directed, (7) enduring—sudden, (8) socially connected—disconnected.

Shors & Matzel provide compelling arguments against a role for hippocampal long-term potentiation (LTP) in mammalian learning and memory. As an alternative, they suggest that LTP is an arousal mechanism. I will argue that this view is not a satisfactory alternative to current conceptions of LTP function.

This paper presents the metaphysics of liberal rights reasoning on one hand and that of demographic reasoning on the other, as exemplifying two worldviews that both compete and complement each other in the contemporary German public debate on demographic decline. First, this essay outlines the way in which liberal theorists of various outlooks, perfectionist and neutralist alike, assume that a wide range of rights serves not only the interests of those individuals who possess them, but that it constitutes the foundations (...) of a just and stable political order in general and therefore is to the advantage of everyone. Second, the essay explains how demographic reasoning questions the assumption of harmony shared by the liberal approaches. Third, it provides an impression of the way in which demographic arguments have been deployed in the public sphere in Germany in the last few years. These arguments associate the autonomy of women with the demise of Germany. They claim that by encouraging women to pursue self-realization as self-interested individuals, the modern secular ethos of Germany as a democratic welfare society may be self-destructive in the long run, since it leads to sub-replacement fertility. Finally, the essay stresses that liberal and demographic perspectives share a “blindness” of historical events. In response, the conclusion brings history back in, by historicizing both demographic reasoning and demographic developments in Germany, with the aim of defusing some of the anxieties that may have been aroused by the current debate.

For many years emotion theory has been characterized by a dichotomy between the head and the body. In the golden years of cognitivism, during the nineteen-sixties and seventies, emotion theory focused on the cognitive antecedents of emotion, the so-called “appraisal processes.” Bodily events were seen largely as byproducts of cognition, and as too unspecific to contribute to the variety of emotion experience. Cognition was conceptualized as an abstract, intellectual, “heady” process separate from bodily events. Although current emotion theory has moved (...) beyond this disembodied stance by conceiving of emotions as involving both cognitive processes (perception, attention, and evaluation) and bodily events (arousal, behavior, and facial expressions), the legacy of cognitivism persists in the tendency to treat cognitive and bodily events as separate constituents of emotion. Thus the cognitive aspects of emotion are supposedly distinct and separate from the bodily ones. This separation indicates that cognitivism’s disembodied conception of cognition continues to shape the way emotion theorists conceptualize emotion. (shrink)

The October 1996 issue of Life magazine included, among other things, a photograph of Marilyn Monroe naked.1 Most people will agree that had the same picture appeared in the pages of Hustler, it would have been pornographic. Furthermore, the picture was considered pornographic when it originally appeared in a calendar in the late 1940’s, and it was banned in two states. But is it pornography in the pages of Life? Should Life have warned its readers that the October 1996 issue (...) was an “adults only” issue, to be sold only from the top shelf of the magazine rack? Perhaps one will say that the difference is that in Hustler and in the calendar in which it originally appeared, but not in Life, the picture would have been treated primarily as a source of sexual arousal. But that can’t be the whole story. It is a common joke that generations of American boys have treated the Sears catalog and National Geographic primarily as sources of sexual arousal without thereby making them pornographic. Or perhaps one will say that the difference is that the producers of the calendar and of Hustler but not the producers of Life ~or of the Sears catalog and National Geographic! intend for the pictures they publish to be treated primarily as sources of arousal. But. (shrink)

What is the relation between emotional experience and its behavioural expression? As very preliminary clarification, I mean by ‘emotional experience’ such things as the subjective feeling of being afraid of something, or of being angry at someone. On the side of behavioural expression, I focus on such things as cowering in fear, or shaking a fist or thumping the table in anger. Very crudely, this is behaviour intermediate between the bodily changes which just happen in emotional arousal, such as (...) sweating or the secretion of adrenalin, and reasoned actions done ‘out of an emotion’, such as breathing deeply to clam down, or writing a letter of complaint, for which a standard rationalizing explanation can be given.1 I pursue the relation between this experience and expression in a somewhat roundabout manner. First, I note an analogy between a problem of other minds, and Berkeley’s (1975) challenge to Locke’s (1975) realism. Second, I sketch what I regard as the correct strategy for meeting this challenge. Third, I develop and defend a parallel response to the problem of other minds, as this applies to certain basic directed emotions. This yields the following answer to my opening question. Reference to the appropriate expressive behaviour is essential to the identification of the way in which various emotional experiences present their worldly objects. (shrink)

The paradigmatic assumption that REM sleep is the physiological equivalent of dreaming is in need of fundamental revision. A mounting body of evidence suggests that dreaming and REM sleep are dissociable states, and that dreaming is controlled by forebrain mechanisms. Recent neuropsychological, radiological, and pharmacological findings suggest that the cholinergic brain stem mechanisms that control the REM state can only generate the psychological phenomena of dreaming through the mediation of a second, probably dopaminergic, forebrain mechanism. The latter mechanism (and thus (...) dreaming itself) can also be activated by a variety of nonREM triggers. Dreaming can be manipulated by dopamine agonists and antagonists with no concomitant change in REM frequency, duration, and density. Dreaming can also be induced by focal forebrain stimulation and by complex partial (forebrain) seizures during nonREM sleep, when the involvement of brainstem REM mechanisms is precluded. Likewise, dreaming is obliterated by focal lesions along a specific (probably dopaminergic) forebrain pathway, and these lesions do not have any appreciable effects on REM frequency, duration, and density. These findings suggest that the forebrain mechanism in question is the final common path to dreaming and that the brainstem oscillator that controls the REM state is just one of the many arousal triggers that can activate this forebrain mechanism. The “REM-on” mechanism (like its various NREM equivalents) therefore stands outside the dream process itself, which is mediated by an independent, forebrain “dream-on” mechanism. Key Words: acetylcholine; brainstem; dopamine; dreaming; forebrain; NREM; REM; sleep. (shrink)

While the influence of emotion on individuals'' ethical decisions has been identified by numerous researchers, little is known about how emotions influence individuals'' ethical decision process. Thus, it is not clear whether different emotions promote and/or discourage ethical decision-making in the workplace. To address this gap, this paper develops a model that illustrates how emotion affects the components of individuals'' ethical decision-making process. The model is developed by integrating research findings that consider the two dimensions of emotion, arousal and (...) feeling state, into an applied cognitive-developmental perspective on the process of ethical decision-making. The model demonstrates that certain emotional states influence the individual''s propensity to identify ethical dilemmas, facilitate the formation of the individual''s prescriptive judgments at sophisticated levels of moral development, lead to ethical decision choices that are consistent with the individual''s prescriptive judgements, and promote the individual''s compliance with his or her ethical decision choices. In particular, the model suggests that individuals experiencing arousal and positive affect resolve ethical dilemmas in a manner consistent with more sophisticated cognitive moral structures. Implications for theory and practice are discussed. (shrink)

The neurobiological systems that mediate the basic emotions are beginning to be understood. They appear to be constituted of genetically coded, but experientially refined executive circuits situated in subcortical areas of the brain which can coordinate the behavioral, physiological and psychological processes that need to be recruited to cope with a variety of primal survival needs (i.e., they signal evolutionary fitness issues). These birthrights allow newborn organisms to begin navigating the complexities of the world and to learn about the values (...) and contingencies of the environment. Some of these systems have been identified and characterized using modern neuroscientific and psychobiological tools. The fundamental emotional systems can now be defined by the functional psychobiological characteristics of the underlying circuitries ? characteristics which help coordinate behavioral, physiological and psychological aspects of emotionality, including the valenced affective feeling states that provide fundamental values for the guidance of behavior. The various emotional circuits are coordinated by different neuropeptides, and the arousal of each system may generate distinct affective/neurodynamic states and imbalances may lead to various psychiatric disorders. The aim of this essay is to discuss the underlying conceptual issues that must be addressed for additional progress in understanding the nature of primary process affective consciousness. (shrink)

Emotion theorists tend to separate “arousal” and other bodily events such as “actions” from the evaluative component of emotion known as “appraisal.” This separation, I argue, implies phenomenologically implausible accounts of emotion elicitation and personhood. As an alternative, I attempt a reconceptualization of the notion of appraisal within the so-called “enactive approach.” I argue that appraisal is constituted by arousal and action, and I show how this view relates to an embodied and affective notion of personhood.

In this address, I outline my “Exotic-Becomes-Erotic" theory of sexual orientation (Bem, 1996) , which provides the same basic account for both opposite-sex and same-sex erotic desire—and for both men and women. It proposes that biological variables do not code for sexual orientation per se but for childhood temperaments that influence a child’s preferences for sextypical or sex-atypical activities. These preferences lead children to feel different from opposite-sex or same-sex peers—to perceive them as “exotic.” This, in turn, produces heightened physiological (...) arousal that subsequently gets eroticized to that same class of peers: Exotic becomes erotic. The theory claims to accommodate both the empirical evidence of the biological essentialists and the cultural relativism of the social constructionists. I also discuss sex differences in sexual orientation and the political implications of trying to explain homosexuality. (shrink)

The literature on time perception is discussed. This is done with reference both to the ''cognitive-timer'' model for time estimation and to the subjective experience of apparent duration. Three assumptions underlying the model are scrutinized. I stress the strong interplay among attention, arousal, and time perception, which is at the base of the cognitive-timer model. It is suggested that a multiplicative function of two key components (the number of subjective time units and their size) should predict apparent duration. Implications (...) for other cognitive domains are drawn, and in particular an analogy is suggested between apparent duration and apparent movement. (shrink)

I argue that our experience of expressive properties (such as the joyfulness or sadness of a piece of music) essentially involves the sensuous imagination (through simulation) of an emotion-guided process which would result in the production of the properties which constitute the realisation of the expressive properties experienced. I compare this proposal with arousal theories, Wollheim’s Freudian account, and other more closely related theories appealing to imagination such as Kendall Walton’s. I explain why the proposal is most naturally developed (...) in terms of simulation and briefly comment upon the impact of work on cross-cultural perception of facial expression, modularity and autism for the proposal.

This article reviews some of the ways in which philosophical problems concerning music can be informed by approaches from the cognitive sciences (principally psychology and neuroscience). Focusing on the issues of musical expressiveness and the arousal of emotions by music, the key philosophical problems and their alternative solutions are outlined. There is room for optimism that while current experimental data does not always unambiguously satisfy philosophical scrutiny, it can potentially support one theory over another, and in some cases allow (...) us to synthesize or reject traditional philosophical differences.

Descriptions of music in terms of emotion are metaphorical, or so I maintain. If so, it is a mistake to say that music “expresses”, “arouses” or “represents” the emotions that figure in those metaphorical descriptions. For the description of those relations between music and emotion would be literal: they would describe a relation – expression, arousal, representation – that holds between music and real emotion. And if that were the case, descriptions of music in terms of emotion would not (...) be metaphorical. Once we embrace a metaphor theory, we should dispense with such relational theories of musical description. I have argued elsewhere for the claim that emotion descriptions of music are metaphorical, and I do not want to revisit that question here.1 I here assume this, so that we can engage with the following issue. Where a metaphorical description is appropriate we can ask why. What makes it appropriate? Since music is often metaphorically described in terms of emotion, we can ask this question of these metaphorical descriptions. We can ask what makes metaphorical emotion descriptions of music appropriate, both in general and in particular cases. That is, we can ask: in general why is it peculiarly appropriate to describe music in terms of emotion? And we can ask: why are particular metaphorical emotion descriptions of particular pieces or stretches of music appropriate? There are some who insist that emotion descriptions of music are literal, but say that they have a secondary literal meaning.2 I find such a view implausible, but for present purposes I could concede that it is theoretically an option. For such a view still incurs the duty to explain the appropriateness, not of a metaphor, but of the supposed secondary literal sense. We would now have the question: what is the relation between the two senses such that not only is it not a coincidence, but also such that it is appropriate that the two senses are expressed by the same word? A similar issue is raised whether we opt for a metaphorical view or a secondary literal meaning view. Now some writers have sought a unitary account of the appropriateness of emotion descriptions of music.. (shrink)

The concept of representation has been a key element in the scientific study of mental processes, ever since such studies commenced. However, usage of the term has been all but too liberal—if one were to adhere to common use it remains unclear if there are examples of physical systems which cannot be construed in terms of representation. The problem is considered afresh, taking as the starting point the notion of activity spaces—spaces of spatiotemporal events produced by dynamical systems. It is (...) argued that representation can be analyzed in terms of the geometrical and topological properties of such spaces. Several attributes and processes associated with conceptual domains, such as logical structure, generalization and learning are considered, and given analogues in structural facets of activity spaces, as are misrepresentation and states of arousal. Based on this analysis, representational systems are defined, as is a key concept associated with such systems, the notion of representational capacity. According to the proposed theory, rather than being an all or none phenomenon, representation is in fact a matter of degree—that is can be associated with measurable quantities, as is behooving of a putative naturalistic construct.

One striking feature of pornographic images is that they emphasize what is depicted and underplay the way it is depicted: the experience of pornography rarely involves awareness of the picture’s composition or of visual rhyme. There are various ways of making this distinction between what is depicted in a picture and the way the depicted object is depicted in it. Following Richard Wollheim, I call these two aspects, the ‘what’ and ‘how’ of pictorial representation ‘recognitional’ and ‘configurational’, respectively. Some pictures (...) emphasize one of these aspects while underplaying the other. Pornographic pictures try to trigger as little attention to the ‘configurational’ aspect as possible. Instead of examining pornography, where the ‘configurational’ aspect of experience is underplayed, I focus on a historical attempt to create images of the female body where the ‘recognigional’ element is the one that is underplayed and the ‘configurational’ elements of the picture form an essential part of our experience. The pictures I have in mind are André Kertész’s series of photographs from 1933, called Distortions. I argue that Kertész’s Distortions are in this respect the counterpoint of pornography: they may be the least pornographic representations of the female nude. Instead of ignoring the ‘configurational aspects of the picture, making the picture transparent and fully at the service of showing the female body and thus to trigger arousal, Kertész aims to achieve the exact opposite. His photographs strip the female body of all its sexual connotations and draw our attention to the formal features of the picture – which is quite a feat in the light of the subject matter of these pictures that normally draw our attention away from the formal features of pictures.

Based on recent insight into the thalamocortical system and its role in perception and conscious experience, a unified pathophysiological framework for hallucinations in neurological and psychiatric conditions is proposed, which integrates previously unrelated neurobiological and psychological findings. Gamma-frequency rhythms of discharge activity from thalamic and cortical neurons are facilitated by cholinergic arousal and resonate in networks of thalamocortical circuits, thereby transiently forming assemblies of coherent gamma oscillations under constraints of afferent sensory input and prefrontal attentional mechanisms. If perception is (...) based on synchronisation of intrinsic gamma activity in the thalamocortical system, then sensory input to specific thalamic nuclei may merely play a constraining role. Hallucinations can be regarded as underconstrained perceptions that arise when the impact of sensory input on activation of thalamocortical circuits and synchronisation of thalamocortical gamma activity is reduced. In conditions that are accompanied by hallucinations, factors such as cortical hyperexcitability, cortical attentional mechanisms, hyperarousal, increased noise in specific thalamic nuclei, and random sensory input to specific thalamic nuclei may, to a varying degree, contribute to underconstrained activation of thalamocortical circuits. The reticular thalamic nucleus plays an important role in suppressing random activity of relay cells in specific thalamic nuclei, and its dysfunction may be implicated in the biological vulnerability to hallucinations in schizophrenia. Combined with general activation during cholinergic arousal, this leads to excessive disinhibition in specific thalamic nuclei, which may allow cortical attentional mechanisms to recruit thalamic relay cells into resonant assemblies of gamma oscillations, regardless of their actual sensory input, thereby producing an underconstrained perceptual experience. Key Words: Charles Bonnet syndrome; gamma oscillations; hallucinations; late paraphrenia; Lewy body dementia; perception; schizophrenia; thalamocortical system. (shrink)

It is commonly assumed that the scientific study of emotions should focus on discrete categories such as fear, anger, sadness, joy, disgust, shame, guilt, and so on. This view has recently been questioned by the emergence of the “core affect movement,” according to which discrete emotions are not natural kinds. Affective science, it is argued, should focus on core affect, a blend of hedonic and arousal values. Here, I argue that the empirical evidence does not support the thesis that (...) core affect is a more “natural” category than discrete emotions. I conclude by recommending a splitting strategy in our search for natural affective kinds. †To contact the author, please write to: Andrea Scarantino, Department of Philosophy and Neuroscience Institute, Georgia State University, P.O.

Cruelty is the deliberate infliction of physical or psychological pain on other living creatures, sometimes indifferently, but often with delight. Though cruelty is an overwhelming presence in the world, there is no neurobiological or psychological explanation for its ubiquity and reward value. This target article attempts to provide such explanations by describing three stages in the development of cruelty. Stage 1 is the development of the predatory adaptation from the Palaeozoic to the ethology of predation in canids, felids, and primates. (...) Stage 2, through palaeontological and anthropological evidence, traces the emergence of the hunting adaptation in the Pliocene, its development in early hominids, and its emotional loading in surviving forager societies. This adaptation provides an explanation for the powerful emotions – high arousal and strong affect – evoked by the pain-blood-death complex. Stage 3 is the emergence of cruelty about 1.5 million years ago as a hominid behavioural repertoire that promoted fitness through the maintenance of personal and social power. The resulting cultural elaborations of cruelty in war, in sacrificial rites, and as entertainment are examined to show the historical and cross-cultural stability of the uses of cruelty for punishment, amusement, and social control. Effective violence prevention must begin with perpetrators, not victims. If the upstream approaches to violence prevention advocated by the public-health model are to be effective, psychologists must be able to provide violence prevention workers with a fine-grained understanding of perpetrator gratifications. This is a distasteful task that will compel researchers to interact with torturers and abusers, and to acknowledge that their gratifications are rooted in a common human past. It is nonetheless an essential step in developing effective strategies for the primary prevention of violence. Key Words: compassion; cruelty; entertainment industry; evolutionary psychology; intraspecific killing; pain; predation; punishment; torture; violence prevention.

Empirical evidence shows that non-conscious appraisal processes generate bodily responses to the environment. This finding is consistent with William James’s account of emotion, and it suggests that a general theory of emotion should follow James: a general theory should begin with the observation that physiological and behavioral responses precede our emotional experience. But I advance three arguments (empirical and conceptual arguments) showing that James’s further account of emotion as the experience of bodily responses is inadequate. I offer an alternative model, (...) according to which responses (physical states) are perceived and interpreted by a separate cognitive process, one that assigns meaning to those responses. The non-conscious appraisal process and the interpretive process are distinct, hence a two-stage model of emotion. This model is related to Schachter and Singer’s two-factor theory. Their often-discussed experiment showed that interpretation can play a role in producing emotions. But they do not show that interpretation is necessary for producing emotions in general, outside of the experimental conditions that generated unexplained arousal in subjects. My two-stage model supports this stronger claim by situating the interpretive process in a comprehensive model of emotion. (shrink)

What we perceive is the product of an intrinsic process and not part of external physical reality. This notion is consistent with the philosophical position of transcendental idealism but also agrees with physiological findings on the thalamocortical system. -Frequency rhythms of discharge activity from thalamic and cortical neurons are facilitated by cholinergic arousal and resonate in thalamocortical networks, thereby transiently forming assemblies of coherent oscillations under constraints of sensory input and prefrontal attentional mechanisms. Perception and conscious experience may be (...) based on such assemblies and sensory input to thalamic nuclei plays merely a constraining role in their formation. In schizophrenia, the ability of sensory input to modulate self-organisation of thalamocortical activity may be generally reduced. If during arousal thalamocortical self-organisation is underconstrained by sensory input, then attentional mechanisms alone may determine the content of perception and hallucinations may arise.

This article examines the neurobiological basis of the healing power attributed to shamanic practices in the Andes and Brazil in light of the pharmacology of neurotransmitters and the new technological explorations of brain functioning. The psychotropic plants used in shamanic psychiatric cures interfere selectively with the intrinsic neuromediators of the brain. Mainly they may alter: (1) the neuroendocrine functioning through the adrenergic system by controlling stressful conditions, (2) the dopaminergic system in incentive learning and emotions incorporation, (3) the serotoninergic system (...) in modulating behaviors, and mood, and (4) basic functions implied in anxiety or depression. PET scans and functional magnetic resonance imaging studies of hypnotic trance and altered states of consciousness may provide a useful model for the neurophysiological phenomena of shamanic drum-and-dance trance. The reorganization of cortical areas and the direct interconnections between the prefrontal cortex and the dopaminergic reward centers in the limbic system are of particular significance for human social judgment and symbolic processing. Those centers—including the hypothalamus and the amygdala (associated with psychosomatic equilibrium, memory, and emotion) are enhanced. This arousal may be amplified in order to induce a cathartic crisis—the shamanic trance. It is suggested that through this holistic approach the shaman empirically interferes in neurobiological dysfunctions. (shrink)

No single theory of the emotions dominates the whole of the Middle Ages. Instead, there are several competing accounts, and differences of opinion — sometimes quite dramatic — within each account. Yet there is consensus on the scope and nature of a theory of the emotions, as well as on its place in affective psychology generally. For most medieval thinkers, emotions are at once cognitively penetrable and somatic, which is to say that emotions are influenced by and vary with changes (...) in thought and belief, and that they are also bound up, perhaps essentially, with their physiological manifestations. This ‘mixed’ conception of emotions was broad enough to anchor medieval disagreements over details, yet rich enough to distinguish it from other parts of psychology and medicine. In particular, two kinds of phenomena, thought to be purely physiological, were not considered emotions even on this broad conception. First, what we now classify as drives or urges, for instance hunger and sexual arousal, were thought in the Middle Ages to be at best ‘pre-emotions’ fpropayyioney): mere biological motivations for action, not having any intrinsic cognitive object. Second, moods were likewise thought to be non-objectual somatic states, completely explicable as an imbalance of the bodily humours. Depression fmelancholia), for example, is the pathological condition of having an excess of black bile. Medieval theories of emotions, therefore, concentrate on paradigm cases that fall under the broad conception: delight, anger, distress, fear, and the like. The enterprise of constructing an adequate philosophical theory of the emotions in the Middle Ages had its counterpart in a large body of practical know-how. The medical literature on the emotions, for instance, was extensive, covering such subjects as the causal role of emotions in disease and recovery, the nerves as connecting the brain to the organs involved in the physiological manifestations of the emotions, and the effect of diet and nutrition on emotional responses..

The work ‘Thinking and Feeling’ edited by Robert C. Solomon may be considered as a landmark in the history of the philosophy of the emotions. The work also has assembled together some of the best minds in the Anglo American Traditions. The central focus in this work is to mediate between the physiological arousal theories of emotions and the cognitive appraisal theories of emotions. My article is an attempt to mediate from my Asian background and in specific terms using (...) the Buddhist perspectives on emotion studies, to find answers, a subject on which I have worked over several decades. The Buddha has discouraged people in attempting to find ultimate answers to the body- mind relationships, but use pragmatic and practical perspectives for a two way interactionism. Thus, in the Buddhist analysis the mental and the cognitive, as well as bodily and the physiological are recognised, thus giving room for a holistic understanding of emotions concepts. In fact, Buddhism expects the body, feelings, perceptions, interpretations, and evaluations as facets of emotion concepts. The second point is the domination of the metaphor of reasons as the charioteer in managing unruly emotions in the West. But Buddhism introduces the factor of ‘mindfulness’ as an important ally in the management of emotions. My personal work in therapy and counselling has helped me to explore new dimensions for managing emotions through mindfulness practice. (shrink)

It is argued that constructionist theory provides only a partial account of how secure attachment leads to better social understanding. In addition to cooperative parent-child relations, the more efficient arousal and affect regulation system of secure infants, and developmental moderators of the processes of imitation, may play a part in explaining the association and offer clues as to how effective social understanding is generally acquired.

Written with clarity, wit, and rigor, The Philosophy of Art provides an incisive account of the core topics in the field. The first volume in the new Foundations of the Philosophy of the Arts series, designed to provide crisp introductions to the fundamental general questions about art, as well as to questions about the several arts (such as literature, music or painting). Presents a clear and insightful introduction to central topics and on-going debates in the philosophy of art. Eight sections (...) cover a wide spectrum of topics such as the interpretation of art, the relation between art and moral values, and the expression and arousal of emotion through art. Pedagogical features include full-color illustrations, vibrant examples, thought-provoking discussion questions and helpful suggested readings. (shrink)

Motivation and emotion are not clearly defined and differentiated in Rolls's The brain and emotion, reflecting a widespread problem in conceptualizing these phenomena. An adequate theory of emotion cannot be based upon reward and punishment alone. Basic mechanisms of arousal, agonistic, and prosocial motives-emotions exist in addition to reward-punishment systems.

The models of internal self-control that have recently been proposed by behavioral economists do not depict motivational interaction that occurs while temptation is present. Those models that include willpower at all either envision a faculty with a motivation ( strength ) different from the motives that are weighed in the marketplace of choice, or rely on incompatible goals among diverse brain centers. Both assumptions are questionable, but these models’ biggest problem is that they do not let resolutions withstand re-examination while (...) being challenged by impulsive alternatives. The economists’ models all attempt to make a single equilibrium preference predictable from a person’s prior incentives. This was the original purpose of these models’ hyperboloid ( β–δ ) delay discount functions, which have been widely justified by the assumption that a person’s intertemporal inconsistency (impulsiveness) can be accounted for by the arousal of appetite for visceral rewards. Although arousal is clearly a factor in some cases of intertemporal inconsistency, it cannot be blamed for others, and furthermore does not necessarily imply hyperboloid discounting. The inadequacy of β–δ functions is particularly evident in models of internal self-control. I have reviewed several of these models, and have argued for a return to pure hyperbolic discount function as originally proposed, the relatively high tails of which can motivate a recursive process of self-prediction and thereby the formation of self-enforcing intertemporal contracts. Such a process does not require a separately motivated faculty of will, or incompatible goals among brain centers; but it also does not permit the prediction of unique preferences from prior incentives.

, Derek Matravers defends a new version of the arousal theory of musical expressiveness. In this paper it is argued that for various reasons, including especially what the theory implies about the inappropriateness of certain kinds of response to music, we should reject Matravers's theory in favour of some form of cognitivism.

A developmental theory of erotic/romantic attraction is presented that provides the same basic account for opposite-sex and same-sex desire in both men and women. It proposes that biological variables, such as genes, prenatal hormones, and brain neuroanatomy, do not code for sexual orientation per se but for childhood temperaments that influence a child's preferences for sex-typical or sex-atypical activities and peers. These preferences lead children to feel different from opposite-or same-sex peers — to perceive them as dissimilar, unfamiliar, and exotic. (...) This, in turn, produces heightened nonspecific autonomic arousal that subsequently gets eroticized to that same class of dissimilar peers: Exotic becomes erotic. Specific mechanisms for effecting this transformation are proposed. The theory claims to accommodate both the empirical evidence of the biological essen-. (shrink)

This essay offers a start on sorting out the relationships of argumentation and persuasion by identifying two systematic ways in which definitions of argumentation differ, namely, their descriptions of the ends and of the means involved in argumentative discourse. Against that backdrop, the traditional “conviction-persuasion” distinction is reassessed. The essay argues that the traditional distinction correctly recognizes the difference between the end of influencing attitudes and that of influencing behavior—but that it misanalyzes the means of achieving the latter (by focusing (...) on emotional arousal) and that it mistakenly contrasts “rational” and “emotional” means of influence. The larger conclusion is that understanding the relationships of the phenomena of argumentation and persuasion will require close attention to characterizations of communicative ends and means.

Several recent lines of inquiry have pointed to the amygdala as a potential lesion site in autism. Because one function of the amygdala may be to produce autonomic arousal at the sight of a signi¢cant face, we compared the responses of autistic children to their mothers’ face and to a plain paper cup. Unlike normals, the autistic children as a whole did not show a larger response to the person than to the cup. We also monitored sympathetic activity in (...) autistic children as they engaged in a wide range of everyday behaviours. The children tended to use self-stimulation activities in order to calm hyper-responsive activity of the sympathetic (`¢ght or £ight’) branch of the autonomic nervous system. A small percentage of our autistic subjects had hyporesponsive sympathetic activity, with essentially no electrodermal responses except to self-injurious behaviour. We sketch a hypothesis about autism according to which autistic children use overt behaviour in order to control a malfunctioning autonomic nervous system and suggest that they have learned to avoid using certain processing areas in the temporal lobes.

Pain is an important focus for consciousness research because it is an avenue for exploring somatic awareness, emotion, and the genesis of subjectivity. In principle, pain is awareness of tissue trauma, but pain can occur in the absence of identifiable injury, and sometimes substantive tissue injury produces no pain. The purpose of this paper is to help bridge pain research and consciousness studies. It reviews the basic sensory neurophysiology associated with tissue injury, including transduction, transmission, modulation, and central representation. In (...) addition, it highlights the central mechanisms for the emotional aspects of pain, demonstrating the physiological link between tissue trauma and mechanisms of emotional arousal. Finally, we discuss several current issues in the field of pain research that bear on central issues in consciousness studies, such as sickness and sense of self. (shrink)

I offer an account of theories useful in addressing the question of whether children are young theoreticians whose development can be regarded as the product of theory change. I argue that to regard a set of propositions as a theory is to be committed to evaluating that set in terms of its explanatory power. If theory change is the substance of cognitive development, we should see patterns of affect and arousal consonant with the emergence and resolution of explanation-seeking curiosity. (...) Affect has largely been ignored as a potential source of support or disconfirmation for the "theory theory" of development. (shrink)

In this article I evaluate recent attempts to illuminate the human infant cry from an evolutionary perspective. Infants are born into an uncertain parenting environment, which can range from indulgent care of offspring to infanticide. Infant cries are in large part adaptations that maintain proximity to and elicit care from caregivers. Although there is not strong evidence for acoustically distinct cry types, infant cries may function as a graded signal. During pain-induced autonomic nervous system arousal, for example, neural input (...) to the vocal cords increases cry pitch. Caregivers may use this acoustic information, together with other cues, to guide caregiving behavior. Serious pathology, on the other hand, results in chronically and severely abnormal cry acoustics. Such abnormal crying may be a proximate cause of adaptive infant maltreatment, in circumstances in which parents cut their losses and reduce or withdraw investment from infants with low survival chances. An increase in the amount of crying during the first few months of life is a human universal, and excessive crying, or colic, represents the upper end of this normal increase. Potential signal functions of excessive crying include manipulation of parents to acquire additional resources, honest signaling of need, and honest signaling of vigor. Current evidence does not strongly support any one of these hypotheses, but the evidence is most consistent with the hypothesis that excessive early infant crying is a signal of vigor that evolved to reduce the risk of a reduction or withdrawal of parental care. Key Words: colic; crying; early infant crying; honest signaling; infanticide; parental care; parent-offspring conflict; separation call; vocalization. (shrink)

In a 1967 article, A. C. Graham made the claim that 情 qing should never be translated as "emotions" in rendering early Chinese texts into English. Over time, sophisticated translators and interpreters have taken this advice to heart, and qing has come to be interpreted as "the facts" or "what is genuine in one." In these English terms all sense of interrelationality is gone, leaving us with a wooden, objective stasis. But we also know, again partly through the work of (...) Graham, that interrelationality was of fundamental importance in the early Chinese cosmology and that qing, by later carrying the meaning of "emotions," expressed that interrelationality. I take as my project in this article the recovery of an emotional adumbration in the qing of early Chinese texts, notably the Mencius, from which Graham begins his discussion. With an eye to explicating qing in the Mencius, and with a sensitivity to an implied notion of interrelationality in early texts, I survey early literature from the Shu Jing to late commentaries on the Yi Jing. I find that usages of qing and contexts in which qing is used inevitably illuminate it as key term in the evocation of interrelationality, shading it with emotional overtones. Emotions, of course, are inherently interrelational, and even more so in a Chinese world in which the internal and the external are in constant communication by way of a cosmic interchange of arousal and response among all things. That qing, as a term which later comes to explicitly mean "emotions," should have a centuries old convention of emotional connotation prior to its explicit definition should come as no surprise. The corroboration of this supposition entails a complex investigation and analysis, however, and it is a preliminary step in this investigation and analysis that I undertake here. (shrink)

What we perceive is the product of an intrinsic process and not part of external physical reality. This notion is consistent with the philosophical position of transcendental idealism but also agrees with physiological findings on the thalamocortical system. -Frequency rhythms of discharge activity from thalamic and cortical neurons are facilitated by cholinergic arousal and resonate in thalamocortical networks, thereby transiently forming assemblies of coherent oscillations under constraints of sensory input and prefrontal attentional mechanisms. Perception and conscious experience may be (...) based on such assemblies and sensory input to thalamic nuclei plays merely a constraining role in their formation. In schizophrenia, the ability of sensory input to modulate self-organisation of thalamocortical activity may be generally reduced. If during arousal thalamocortical self-organisation is underconstrained by sensory input, then attentional mechanisms alone may determine the content of perception and hallucinations may arise.

In drawing on my own research and collaborative work with Karl Pribram, I show that love (affective attachment) and power (social control) play a central role in psychosocial evolution. When these relations are coupled in a self-regulating system of cooperative interactions, brain growth is stimulated, mind and agency develop, and stable forms of collective social organization are generated. Focusing on the endogenous dynamics of social collectives, the article is organized in four parts. (A "social collective" is defined as a (...) durable arrangement of relations among two or more individuals that is distinguished by shared membership and collaboration in relation to a common function or goal.) Part I summarizes evidence from developmental neuropsychology and social science to show that stable psychosocial organization, across the human life span, is associated with social interaction organized along two dimensions. One dimension involves love, positive affective attachment, and the second involves power, social regulation of the aroused affective energy. Part II draws on Piaget's theory of cooperation and Bradley and Pribrams' theory of communication to describe how mind and agency are generated, and how stable organization is produced, respectively, from the relations involved in the arousal and regulation of affective energy. Combining elements of the two theories, Part III presents a sketch of a holographic model of collective organization in which goal-directed behavior is generated by a feed-forward process involving imaging and information processing of interaction along the two dimensions. Part IV shows how the model accounts for the emergence of human agency within the context of a more general evolutionary theory, such as Laszlo's. The article concludes with a discussion of my approach for building a "fully human theory of evolution.". (shrink)

I focus on a number of issues arising from Depue & Collins's target article that require further consideration: (1) data that fail to confirm extraversion effects in positive incentive experiments; (2) the role of personality factors, other than extraversion, in dopamine agonism on positive mood states; (3) the role of extraversion in nonspecific arousal, indicating that extraversion may not be an homogeneous trait; and (4) the problem of identifying neurobiologically important traits from existing structural models of personality. I applaud (...) the heuristic value of the model presented and suggest ways in which aspects of the model may be used to identify the personality traits associated with positive incentive motivation.

Neuronal aggregates involved in conscious awareness are not evenly distributed throughout the CNS but comprise key components referred to as the neural network correlates of consciousness (NNCC). A critical node in this network is the posterior cingulate, precuneal, and retrosplenial cortices. The cytological and neurochemical composition of this region is reviewed in relation to the Brodmann map. This region has the highest level of cortical glucose metabolism and cytochrome c oxidase activity. Monkey studies suggest that the anterior thalamic projection likely (...) drives retrosplenial and posterior cingulate cortex metabolism and that the midbrain projection to the anteroventral thalamic nucleus is a key coupling site between the brainstem system for arousal and cortical systems for cognitive processing and awareness. The pivotal role of the posterior cingulate, precuneal, and retrosplenial cortices in consciousness is demonstrated with posterior cingulate epilepsy cases, midcingulate lesions that de-afferent this region and are associated with unilateral sensory neglect, observations from stroke and vegetative state patients, alterations in blood flow during sleep, and the actions of general anesthetics. Since this region is critically involved in self reflection, it is not surprising that it is similarly a site for the NNCC. Interestingly, information processing during complex cognitive tasks and during aversive sensations such as pain induces efforts to terminate self reflection and result in decreased processing in posterior cingulate and precuneal cortices.

In 'Belief-In and Belief in God' ("Religious Studies", 28, 1992), J. N. Williams suggests that belief in God cannot be rational unless one has rational beliefs that God exists. While agreeing with his conclusion (though not with his statement of it), I disagree at almost every step with his method of arriving at it. In particular I suggest that Williams goes astray concerning the dual aspect of belief in, the nature of performatives, the arousal of belief states, and the (...) correct account of belief in God.

The primary purpose of depictive works of pornography, we take it, is sexual arousal through sexually explicit representations; what we callprototypical pornography satisfies those aims through the adoption of a ceteris paribus maximally realistic depictive style. Given that the purpose of sexual arousal seems best fulfilled by establishing the most robust connections between the viewer and the depictive subject, we find it curious that not all works of pornography aspire to prototypical status. Accordingly, we target for philosophical scrutiny (...) several non-standard but putatively pornographic forms: Tijuana Bibles, hentai manga, and slash-fiction. We find that works of these genres possess certain depictively or fictively oriented properties that appear at least prima facie incompatible with prototypical pornography, and thereby to pose two pressing questions that anyprima facie viable analysis of pornography must answer: the depiction question and the fiction question. By answering these questions, we can not only arrive at a deeper understanding of the aims of pornography and the reasons for which significant sub-genres of pornography might diverge from the prototypical ideal, but also perhaps better understand what lies at pornography’s edge, and so better understand the ways in which pornography might relate to what lies beyond.

Hume claims that moral assessments refer to character; it is character of which we morally approve and disapprove. This essay explores what Hume means by “character.” Is it true that moral assessments refer to character, and should Hume think this given his other commitments in moral philosophy and moral psychology? I discuss two prominent themes—namely, Hume’s views on moral responsibility; and Hume’s comparison of moral feelings with feelings of love—to see what light these themes can shed on Hume’s broader views (...) about moral assessment. I argue that at least according to a traditional understanding of the term, character could not plausibly have a role to play in Hume’s account of moral assessment, but that Hume’s moral theory could require a conception of character different from this traditional one: a conception according to which character need not be the standard one that holds character to be consistent, stable, and well-integrated. In morally assessing others, we do not do so on the basis of their characters (at least in any robust sense of character), but on the basis of their motivational states. My account of Hume’s theory of the responsibility, passions and the moral sentiments leaves intact the central Humean insights about the conditions for action and the arousal of the moral sentiment, suggesting what Hume could have said, both more plausibly and without undermining the key features of his moral psychology. And it also shows that Hume’s moral theory has no need for a robust conception of character. (shrink)

US Supreme Court rulings concerning sanctions for juvenile offenders have drawn on the science of brain development and concluded that adolescents are inherently less mature than adults in ways that render them less culpable. This conclusion departs from arguments made in cases involving the mature minor doctrine, in which teenagers have been portrayed as comparable to adults in their capacity to make medical decisions. I attempt to reconcile these apparently incompatible views of adolescents’ decision-making competence. Adolescents are indeed less mature (...) than adults when making decisions under conditions that are characterized by emotional arousal and peer pressure, but adolescents aged 15 and older are just as mature as adults when emotional arousal is minimized and when they are not under the influence of peers, conditions that typically characterize medical decision-making. The mature minor doctrine, as applied to individuals 15 and older, is thus consistent with recent research on adolescent development. (shrink)

Depue & Collins propose that extraversion should be separated from the impulsivity-constraint dimension of personality, and that the VTA dopamine system is the primary engine of extraversion. Although their focus is on personality traits, it may be useful to consider the evidence on psychological state changes, related both to affective arousal and to drug effects. This evidence shows that there are inherent relations between extraversion and impulsivity-constraint, and that there are influences of dopamine on impulsivity-constraint that are not consistent (...) with the Depue & Collins model. Increased positive affect leads to increased extraversion, and this is associated with more impulsivity and less constraint. The evidence on drug effects shows that greater dopaminergic control is associated with more constraint, and with anxiety and vigilance rather than positive affect. (shrink)

Durkheimian solidarity, especially in regard to religion, is reanalyzed in terms of recent developments in the neurosciences and evolution. Neurophysiological studies indicate that religious arousers can piggyback on reward circuitry established by natural selection for interpersonal attachments. This piggybacking is rooted in uneven evolutionary changes in cognitive capacities, emotional arousal capabilities, and preconscious screening rules for rewarding arousal release. Uneven development means that only a special class of enhanced arousers embedded in macro social structures can tap some of (...) the reservoirs of expanded arousal release protected by these screening rules. It becomes imperative that part of collective social life offers these special arouser packages. Beginning with religion and inequality, the social construction of enhanced arousers leaves a trail across human history. However, this trail is not quite what Durkheim had in mind. (shrink)

The standard account of arousal seems on the surface relatively straight forward. Its basic meaning is to awaken someone, reading him for activity. Physiologically, this involves stimulating the cerebral cortex into a general state of wakefulness and attention. The aroused subject shows an increased heart rate and blood pressure. Psychologically, sensory alertness, mobility and readiness to respond all mark the aroused state. As all the experts agree, arousal involves more than the simple presence of an external stimulation. It (...) requires impulses that are external and internal to the body. To be effective, the external impulses must find a corresponding response. Thus, it is no good trying to wake someone up by a sound outside of the range of his hearing. Similarly, the genital displays of one species will not cause sexual arousal in another. In neither case, can the external impulses activate the inner impulses or drives. This requires the presence of appropriate stimuli. Thus, the sight and smell of food arouses appetite. It awakens the drive of hunger, which is directed towards the food. Similarly, the sight, odor and touch of the sexual partner brings about sexual arousal and activation of the corresponding sexual drive. Even in the case of arousal from sleep by such varied stimuli as a light being turned on, a noise, or the touch of a person fit into the pattern of an inner impulse or drive being activated by an external impulse. The drive in this case is towards the various stimuli that our senses prime us to receive. Our need for such is as basic as that for food. Placed in a situation of sensory deprivation, the mind attempts to make up their loss by generating hallucinations. The German phenomenologist, Edmund Husserl, spoke in this context of “non-objectifying instincts.” They designate an instinctive “interest in the data and fields of sensation—before the objectification of sense data,” that is, before there is “a thematically actualizable object” for the drive to fasten on.[i] In each of these examples, hunger, sex, or simple sensation, the external stimuli trigger internal processes primed to response..

Early theorists (Freud and Darwin) speculated that extremely shy children, or those with anxious temperament, were likely to have anxiety problems as adults. More recent studies demonstrate that these children have heightened responses to potentially threatening situations reacting with intense defensive responses that are characterized by behavioral inhibition (BI) (inhibited motor behavior and decreased vocalizations) and physiological arousal. Confirming the earlier impressions, data now demonstrate that children with this disposition are at increased risk to develop anxiety, depression, and comorbid (...) substance abuse. Additional key features of anxious temperament are that it appears at a young age, it is a stable characteristic of individuals, and even in non-threatening environments it is associated with increased psychic anxiety and somatic tension. To understand the neural underpinnings of anxious temperament, we performed imaging studies with 18- fluoro-deoxyglucose (FDG) high-resolution Positron Emission Tomography (PET) in young rhesus monkeys. Rhesus monkeys were used because they provide a well validated model of anxious temperament for studies that cannot be performed in human children. Imaging the same animal in stressful and secure contexts, we examined the relation between regional metabolic brain activity and a trait-like measure of anxious temperament that encompasses measures of BI and pituitaryadrenal reactivity. Regardless of context, results demonstrated a trait-like pattern of brain activity (amygdala, bed nucleus of stria terminalis, hippocampus, and periaqueductal gray) that is predictive of individual phenotypic differences. Importantly, individuals with extreme anxious temperament also displayed increased activity of this circuit when assessed in the security of their home environment. These findings suggest that increased activity of this circuit early in life mediates the childhood temperamental risk to develop anxiety and depression.. (shrink)

Shors & Matzel (1997) suggest replacing the question “Is LTP a mechanism of learning?” with “Is LTP a mechanism of arousal and attention?” However, the failure of experiments to verify the LTP-learning hypothesis may arise not because it is untrue, but because in its current guise, it is not properly testable. If so, then the LTP-attention hypothesis is untestable, as well.

Noradrenergic pathways are involved in mediating the central and peripheral effects of physiological arousal. The aim of the present study was to investigate the role of noradrenergic transmission in moral decision-making. We studied the effects in healthy volunteers of propranolol (a noradrenergic beta-adrenoceptor antagonist) on moral judgement in a set of moral dilemmas pitting utilitarian outcomes (e.g., saving five lives) against highly aversive harmful actions (e.g., killing an innocent person) in a double-blind, placebo-controlled, parallel group design. Propranolol (40 mg (...) orally) significantly reduced heart rate, but had no effect on self-reported mood. Importantly, propranolol made participants more likely to judge harmful actions as morally unacceptable, but only in dilemmas where harms were ‘up close and personal’. In addition, longer response times for such personal dilemmas were only found for the placebo group. Finally, judgments in personal dilemmas by the propranolol group were more decisive. These findings indicate that noradrenergic pathways play a role in responses to moral dilemmas, in line with recent work implicating emotion in moral decision-making. However, contrary to current theorising, these findings also suggest that aversion to harming is not driven by emotional arousal. Our findings are also of significant practical interest given that propranolol is a widely used drug in different settings, and is currently being considered as a potential treatment for post-traumatic stress disorder in military and rescue service personnel.
