Lewis's dynamic systems approach is a refreshing change from the reflexology of most neuroscience, but it could go a step further: It could include the expected rewardingness of an emotion in the recursive feedback loop that determines whether the emotion will occur. Two possible objections to such a model are discussed: that emotions are not deliberate, and that negative emotions should lose out as instrumental choices.

Fractal time fluctuations of the spectral “1/f” form are universal in natural self-organizing systems. Neurobiology is uniquely infused with fractal fluctuations in the form of statistically self-similar clusters or bursts on all levels of description from molecular events such as protein chain fluctuations, ion channel currents and synaptic processes to the behaviors of neural ensembles or the collective behavior of Internet users. It is the thesis of this essay that the brain self-organizes via a vertical collation of these spontaneous events (...) in order to perceive the world and generate adaptive behaviors. REM sleep, which coalesces from self-similar clusters of burst-within-burst behavior during ontogeny, is essential to cognitive-emotional function, and has recurrent fractal organization. Empirical fMRI observations further support the association of fractal fluctuations in the temporal lobes, brainstem and cerebellum during the expression of emotional memory, spontaneous fluctuations of thought and meditative practice. Cognitive-emotional integration arises as amygdaloid-brainstem-cerebellar systems harmonize the vertical “1/f” symphony of coupled isochronous cortical oscillations in the pursuit of mindfulness.

Research only alluded to by Preston & de Waal (P&deW) indicates the disproportionate involvement of some brain regions in the perception and experience of certain emotions. This suggests that the neural substrate of primitive emotional contagion has some emotion-specific aspects, even if cognitively sophisticated forms of empathy do not. Goals for future research include determining the ways in which empathy is emotion-specific and dependent on overt or covert perception.

Two studies explore the frequently reported finding that affective forecasts are too extreme. In the first study, driving test candidates forecast the emotional consequences of failing. Test failers overestimated the duration of their disappointment. Greater previous experience of this emotional event did not lead to any greater accuracy of the forecasts, suggesting that learning about one's own emotions is difficult. Failers' self-assessed chances of passing were lower a week after the test than immediately prior to the test; this difference correlated (...) with the magnitude of individual immediate disappointments, suggesting the presence of a cognitive strategy for recovering from disappointments. A second study investigated the theory that undue focus on the differences between present and future biases affective forecasts. “Defocusing” that induced low-level construals of the future reduced the extremeness of affective forecasts but a higher-level construal did not. We conclude that a focusing effect may bias affective forecasts. (shrink)

Bridging between psychological and neurobiological systems requires that the system components are closely specified at both the psychological and brain levels of analysis. We argue that in developing his dynamic systems theory framework, Lewis has sidestepped the notion of a psychological level systems model altogether, and has taken a partisan approach to his exposition of a brain-level systems model.

Recent research has yielded an explosion of literature that establishes a strong connection between emotional and cognitive processes. Most notably, Antonio Damasio draws an intimate connection between emotion and cognition in practical decision making. Damasio presents a "somatic marker" hypothesis which explains how emotions are biologically indispensable to decisions. His research on patients with frontal lobe damage indicates that feelings normally accompany response options and operate as a biasing device to dictate choice. What Damasio's hypothesis lacks is a theoretical model (...) of decision making which can advance the conceptual connection between emotional and cognitive decision making processes. In this paper we combine Damasio's somatic marker hypothesis with the coherence theory of decision put forward by Thagard and Millgram. The juxtaposition of Damasio's hypothesis with a cognitive theory of decision making leads to a new and better theory of emotional decisions. (shrink)

Rolls's book, The brain and emotion is an important and valuable contribution to our understanding of the brain mechanisms that underlie emotional processes. Its explanatory value is less obvious when it comes to psychological and philosophical issues concerning the nature of emotions.

In this chapter, I outline dynamic models of motivation and emotion. These turn out not to be autonomous subsystems, but, instead, are deeply integrated in the basic interactive dynamic character of living systems. Motivation is a crucial aspect of particular kinds of interactive systems -- systems for which representation is a sister aspect. Emotion is a special kind of partially reflective interaction process, and yields its own emergent motivational aspects. In addition, the overall model accounts for some of the crucial (...) properties of consciousness. (shrink)

Understanding how emotions emerge is difficult without determining what characteristic of the trigger actually triggers them. Knowing whether emotional experiences self-stabilize is difficult without remembering what other processes are set in play as the emotion emerges. It is not clear either that positive feedback is required for the emergence of emotion or that an attractor model captures well what is happening when an emotion arises.

In his target article, Barsalou cites current work on emotion theory but does not explore its relevance for this project. The connection is worth pursuing, since there is a plausible case to be made that emotions form a distinct symbolic information processing system of their own. On some views, that system is argued to be perceptual: a direct connection with Barsalou's perceptual symbol systems theory. Also relevant is the hypothesis that there may be different modular subsystems within emotion and the (...) perennial tension between cognitive and perceptual theories of emotion. (shrink)

This review focuses on the theory of emotion outlined in Chapter 3 of Rolls's The brain and emotion. It is proposed that Rolls's emphasis on a relatively simple neurobiologically derived emotion scheme does not allow him to present a comprehensive account of emotion. Consequently, high-level cognitive processes, such as appraisal, end up being retained in the theory despite Rolls's skepticism about their utility. An argument is put forward that the concept of appraisal in the emotion literature is more than semantic (...) convention and actually allows us to talk about multiple functional-level routes to the generation of emotion – a characteristic of the latest generation of theories in the cognition-emotion literature.

EEG evidence supports the view that each cerebral hemisphere maintains a scale-free network that generates and maintains a global state of chaos. By its own evolution, and under environmental impacts, this hemispheric chaos can rise to heights that may either escape containment and engender incontinent action or be constrained by predictive control and yield creative action of great power and beauty.

Spinoza speculated on how ethics could emerge from biology and psychology rather than disrupt them and recent evidence suggests he might have gotten it right. His radical deconstruction and reconstruction of ethics is supported by a number of avenues of research in the cognitive and neurosciences. This paper gathers together and presents a composite picture of recent research that supports Spinoza’s theory of the emotions and of the natural origins of ethics. It enumerates twelve naturalist claims of Spinoza that now (...) seem to be supported by substantial evidence from the neurosciences and recent cognitive science. I focus on the evidence provided by Lakoff and Johnson in their summary of recent cognitive science in Philosophy in the Flesh: The Embodied Mind and Its Challenge to Western Thought (1999); by Antonio Damasio in his assessment of the state of affective neuroscience in Descartes’ Error (1994) and in The Feeling of What Happens (1999) (with passing references to his recent Looking for Spinoza (2003); and by Giacomo Rizzolatti, Vittorio Gallese and their colleagues in the neural basis of emotional contagion and resonance, i.e., the neural basis of primitive sociality and intersubjectivity, that bear out Spinoza’s account of social psychology as rooted in the mechanism he called attention to and identified as affective imitation.

Attempts to integrate diverse phenomena in terms of common processes are much needed in psychology, but definitional precision is a necessary preliminary to explanation. It is also preferable to use caution in juxtaposing concepts from different realms of discourse.

Rolls discusses various adaptive explanations of physiological processes and the emotions. We give a critical analysis of some of these from the perspective of behavioural ecology. While agreeing with the approach adopted by Rolls, we identify topics that could have been better presented by making use of the existing literature.

Two putative functions of emotion experience — its roles in intentional action and in social understanding — were investigated using a group of individuals (repressors) known to have impaired anxiety experience. Repressors, low-anxious, high-anxious, and defensive high-anxious individuals were asked to give a public presentation, and then given the opportunity to avoid the presentation. Repressors were the group most likely to avoid giving the presentation, but were the least likely to give an emotional explanation for their avoidance. By contrast, they (...) were not less likely than other groups to provide negative emotional explanations of another person’s behaviour in a film clip. We concluded that: (1) repressors are impaired in self- but not in other-explanation using emotion, implying that “simulation” is not the method used by repressors to ground their folk psychology, (2) the intentional avoidance shown by repressors is indicative of some intact first-order phenomenal anxiety experience but that they lack second-order awareness of this anxiety experience.

This paper has two aims: (1) to point the way towards a novel alternative to cognitive theories of emotion, and (2) to delineate a number of different functions that the emotions play in cognition, functions that become visible from outside the framework of cognitive theories. First, I hold that the Higher Order Representational (HOR) theories of consciousness — as generally formulated — are inadequate insofar as they fail to account for selective attention. After posing this dilemma, I resolve it in (...) such a manner that the following thesis arises: the emotions play a key role in shaping selective attention. This thesis is in accord with A. Damasio’s (1994) noteworthy neuroscientific work on emotion. I then begin to formulate an alternative to cognitive theories of emotion, and I show how this new account has implications for the following issues: face recognition, two brain disorders (Capgras’ and Fregoli syndrome), the frame problem in A. I., and the research program of affective computing. (shrink)

LeDoux (1996) has identified a sub-cortical neural circuit that mediates fear responses in rats. The existence of this neural circuit has been used to support the claim that emotion is a non-cognitive process. In this paper I argue that this sub-cortical circuit cannot have a role in the explanation of emotions in humans. This worry is raised by looking at the properties of this neural pathway, which does not have the capacity to respond to the types of stimuli that are (...) generally taken to trigger emotion responses. In particular, the neurons in this pathway cannot represent the stimulus as a complete object or event, rather they represent the simple information that is encoded at the periphery. If it is assumed that an object or event in the world is what, even in simple cases, causes an emotion, then this sub-cortical pathway has limited use in a theory of emotion. (shrink)

This study investigated the relationship between dream emotion and dream character identification. Thirty-five subjects provided 320 dream reports and answers to questions on characters that appeared in their dreams. We found that emotions are almost always evoked by our dream characters and that they are often used as a basis for identifying them. We found that affection and joy were commonly associated with known characters and were used to identify them even when these emotional attributes were inconsistent with those of (...) the waking state. These findings are consistent with the finding that the dorsolateral prefrontal cortex, associated with short-term memory, is less active in the dreaming compared to the wake brain, while the paleocortical and subcortical limbic areas are more active. The findings are also consistent with the suggestion that these limbic areas have minimal input from the dorsolateral prefrontal cortex in the dreaming brain. (shrink)

Rolls's preliminary definitions of emotion and speculative restriction of consciousness, including emotional sentience, to humans, display behaviorist prejudice. Reinforcement and causation are not by themselves sufficient conceptual resources to define either emotion or the directedness of thought and motivated action. For any adequate definition of emotion or delimitation of consciousness, new physiology, such as Rolls is contributing to, and also the resources of other fields, will be required.

A common objection to adaptationist accounts of human emotions is that they ignore the influence of culture. If complex emotions like guilt, shame and romantic jealousy are largely culturally determined, how could they be biological adaptations? Dual inheritance models of gene/culture coevolution provide a potential answer to this question. If complex emotions are developmentally ‘scaffolded' by norms that are transmitted from parent to offspring with reasonably high fidelity, then these emotions can evolve to promote individual reproductive interests. This paper draws (...) on case studies of emotional development to illustrate how complex emotions satisfy these conditions. Many of the norms and parenting strategies influencing emotional development are absorbed during the early stages of life when a child is in primary contact with its parents and before the onset of complex cognition. These conditions make it likely that emotion-governing norms are transmitted vertically and with relatively little cognitive ‘contamination'. ‡Thanks to Mark Colyvan, Paul Griffiths, Alexander Rosenberg, and John Wilkins for helpful comments on previous drafts. †To contact the author, please write to: Department of Philosophy, University of Queensland, Brisbane, Queensland 4072, Australia; e-mail: s.linquist@uq.edu.au.

Erdelyi argues persuasively for his unified theory of repression. Beyond this, what can studying repression bring to our understanding of other aspects of emotional function? Here we consider ways in which work on repression might inform the study of, on one hand, emotional memory, and on the other, the emotional numbing seen in patients with chronic persistent depersonalization symptoms.

The James–Lange theory considers emotional feelings as perceptions of physiological body changes. This approach has recently resurfaced and modified in both neuroscientific and philosophical concepts of embodiment of emotional feelings. In addition to the body, the role of the environment in emotional feeling needs to be considered. I here claim that the environment has not merely an indirect and thus instrumental role on emotional feelings via the body and its sensorimotor and vegetative functions. Instead, the environment may have a direct (...) and non-instrumental, i.e., constitutional role in emotional feelings; this implies that the environment itself in the gestalt of the person–environment relation is constitutive of emotional feeling rather than the bodily representation of the environment. Since the person–environment relation is crucial in this approach, I call it the relational concept of emotional feeling. After introducing the relational concept of emotional feeling, the present paper investigates the neurophilosophical question whether current neuroimaging data on human emotion processing and anatomical connectivity are empirically better compatible with the “relational” or the “embodied” concept of emotional feeling. These data lend support to the empirical assumption that neural activity in subcortical and cortical midline regions code the relationship between intero- and exteroceptive stimuli in a relational mode, i.e. their actual balance, rather than in a translational mode, i.e., by translating extero- into interoceptive stimulus changes. Such intero-exteroceptive relational mode of neural coding may have implications for the characterization of emotional feeling with regard to phenomenal consciousness and intentionality. I therefore conclude that the here advanced relational concept of emotional feeling may be considered neurophilosophically more plausible and better compatible with current neuroscientific data than the embodied concept as presupposed in the James–Lange theory and its modern neuroscientific and philosophical versions.

Emotion theories in present philosophical discussion propose different models of relationship between feeling and appraisal. The multicomponent model considers appraisal as separate component and distinguishes it from feeling and physiological body changes thus presupposing what may be called 'disembodied' and 'disembedded' appraisal as representational. The recently emerged concept of enactment, in contrast, argues that appraisal is closely linked to feeling and physiological body changes presupposing what can be called 'embodied' and 'embedded' appraisal as relational. The aim of the paper is (...) to investigate which concept of appraisal, the 'disembedded' or the 'embedded' one, is better compatible with current neuroimaging data on emotion processing and thus neurophilosophically more tenable. The 'disembodied' and 'disembedded' concept implies distinct and independent brain regions underlying feeling and appraisal whereas 'embodied' and 'embedded' appraisal implies overlapping and dependent brain regions. Recent neuroimaging studies demonstrate that medial and lateral prefrontal cortical regions are involved in both feeling and appraisal and that there seems to be reciprocal modulation between these regions. Though preliminary, these data suggest that feeling and appraisal are associated with different patterns of neural activity across overlapping and interdependent brain regions. I therefore conclude that current neuroscientific evidence is rather in favor of the 'embodied' and 'embedded' concept of appraisal as relational than the one of 'disembodied' and 'disembedded' appraisal as representational that is presupposed in current multicomponent theories of emotions.
