Unconscious stimuli can influence participants’ motor behavior but also more complex mental processes. Recent research has gradually extended the limits of effects of unconscious stimuli. One field of research where such limits have been proposed is spatial cueing, where exogenous automatic shifts of attention have been distinguished from endogenous controlled processes which govern voluntary shifts of attention. Previous evidence suggests unconscious effects on mechanisms of exogenous shifts of attention. Here, we applied a cue-priming paradigm to a spatial cueing (...) task with arbitrary cues by centrally presenting a masked symmetrical prime before every cue stimulus. We found priming effects on response times in target discrimination tasks with the typical dynamic of cue-priming effects indicating that central symmetrical stimuli which have been associated with endogenous orienting can modulate shifts of spatial attention even when they are masked. Prime–Cue Congruency effects of perceptual dissimilar prime and cue stimuli suggest that these effects cannot be entirely reduced to perceptual repetition priming of cue processing. In addition, priming effects did not differ between participants with good and poor prime recognition performance consistent with the view that unconscious stimulus features have access to processes of endogenous shifts of attention.

A sample of Yukatek Maya children was tested on their capacity to attribute false beliefs to a variety of stimuli, both natural and non-natural. Children's capacity to correctly infer that humans have limited perceptual access, and are, therefore, not likely to know what is inside a container if the contents have been surreptitiously replaced, is shown to have significant consequences. Children who passed the test with the human stimulus showed a nuanced capacity to attribute similar or dissimilar knowledge (...) to other natural and non-natural entities, consistently with these entities' cultural representations. In contrast, those who failed the test with the human stimulus tended to attribute similar beliefs to all natural and non-natural entity stimuli. (shrink)

Although consumers increasingly claim to demand ethical products and state that they are willing to reward firms that are ethical, studies have highlighted that there is a significant gap between consumers’ explicit attitudes toward ethical products and their actual purchase behavior. This has major implications for firm policies revolving around business ethics. This research contributes to the understanding of the attitude–behavior gap in ethical consumption that literature has identified but not explored much. We utilize the model of dual attitudes as (...) a basis for the arguments presented in the paper and test them. We suggest that the gap in ethical consumerism exists because individuals have implicit as well as explicit attitudes, which are impacted differentially by stimuli and elicit dissimilar behavioral responses and thus have different implications for business ethics policies. Two longitudinal studies are conducted to better understand the impact of an individual’s dual attitudes on preferences and choice. Our findings support the presence of dual attitudes in consumers. Explicit attitudes are found to be easily influenced by the nature of the stimuli. On the other hand, implicit attitudes are relatively unaffected by the nature of the stimuli present and remain relatively constant. Based on the findings, implicit attitudes guide behavior and determine an individual’s preferences. Even though explicit attitudes react to the stimuli presented, our findings suggest they have no impact on the choice of consumers. These findings improve the understanding of ethical consumption, provide a reason as to why the attitude–behavior gap exists, provide a foundation for future researchers and help firms better understand the impact of perceived business on creating a behavioral shift in ethical consumption.

How do our brains represent distinct objects in consciousness? In order to consciously distinguish between objects, our brains somehow selectively bind together activity patterns of spatially intermingled neurons that simultaneously represent similar and dissimilar features of distinct objects. Gamma-band synchronous oscillations of neuroelectrical activity have been hypothesized to be a mechanism used by our brains to generate and bind conscious sensations to represent distinct objects. Most experiments relating GSO to specific features of consciousness have been published only in the (...) last several years. This brief review focuses on a wide variety experiments in which animals, including humans, discriminate between sensory stimuli and make these discriminations evident in their behavior. Performance of these tasks, in humans, is invariably accompanied by conscious awareness of both stimuli and behavior. Results of these experiments indicate that specific patterns of GSO correlate closely with specific aspects of conscious sensorimotor processing. That is, GSO appear to be closely correlated with neural generation of our most paradigmatic cognitive state: consciousness. (shrink)

This volume is by no means out of place for a reader in the twenty first century as resemblances between the age of the machine and our own digital age are surprisingly numerous, particularly with reference to the patterns of intellectual response to unprecedented stimuli. The worrisome parallelisms and analogues are purposefully kept off stage for the imaginative audience to complement the plot of the real drama of the Industrial Revolution as it was witnessed by such imaginative medievalist 'knights' (...) as Carlyle, Cobbett, Southey, Pugin, Ruskin and Morris, intelligent thinkers who performed the universal 'type' rather than the subjective or egocentric in so far as their intellectual responses to the discrepancy between two dissimilar epochs was concerned. The reader is, therefore, expected to be engaged with the arguments of the 'neo-feudal', the 'moral-aesthetic' and the utopian 'social-aesthetic' arguments at the core of the book both imaginatively and intellectually. On the first level, he is requested to shuttle between two centuries separated by the length of a different century. On the second, however, he is expected not only to appreciate the artistically excellent literary works of prominent belletrists, but also to examine the clever polemics they developed as methods of treatment and persuasion aiming at a solution of the social and psychological problems that arose from the incongruity between the present and the past, with specific references to such significant concepts as those of time, history, progress and authority which are examined against the superheated touchstones of democratization, liberty, laissez-faire ethics, mechanization, poverty and social protest in the industrial city.

Despite the fact that animal behavior involves a particularly powerful form of niche construction, few researchers have considered how the environmental impact of behavior may feed back to influence the evolution of the cognitive underpinnings of behavior. I explore a model that explicitly incorporates niche construction while tracking cognitive evolution. Agents and their stimuli are modeled as coevolving populations. The agents are born with “weights” attached to behaviors in a repertoire. Further, these agents are able to change these weights (...) based on previous success and an inherited learning parameter. Both the agent and the stimulus receive payoffs through a behavioral interaction . The behaving agent exhibits niche construction through its effects on stimuli , which can feed back to influence the value of different cognitive strategies. Here I focus on two forms of niche construction: the stimulus and responding agent have common interests and the stimulus and agent have dissimilar interests . The form of niche construction qualitatively affects cognitive evolution . Given a mutualism between the stimulus and responding agent, rapid learning and “fixed” behavioral distributions evolve. Given an antagonism between the stimulus and agent, slower learning and “flexible” behavioral distributions evolve. I discuss these results in light of findings from the fields of ethology, psychology, and evolutionary ecology. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:How to Reason Beyond Reason? Toward a Philosophical Understanding of MadnessWouter Kusters, PhD (bio)To analyze the situation of madness on the ground, we need a grounded perspective, close to the situation at hand. The closer we come to the subject under scrutiny, the clearer its outlines, fine-grained details, and its dynamics, and the better we reach an explanation and understanding. The closer the approach, however, the higher the chances (...) are of becoming myopic and losing the connections with broader—or higher—perspectives: the view from above. It has been due to philosophical and historical approaches from above to the practices of philosophically inspired psychiatry that we may gain new insights into what is going on on the ground—and underground. This article by Garson provides such a view that may lead to a change in perspective, a new way to draw boundaries on the ground, to discover similarities and dissimilarities through space and time, without thereby losing the lived connection to the problematic ground.Garson proposes to replace a binary opposition of madness (in the sense of sick or insane) versus sanity (in the sense of healthy), with a triad of concepts, sanity, madness, and idiocy, taken from the work of philosophers of psychiatry avant la lettre in the early modern times, Locke, Kant, Wigan, and Heinroth. This triad is to be understood in terms of reason, where idiocy consists of the diminishment of some aspects of reason, while madness would be characterized by a perversion of reason. By examining how this perversion—or more neutrally said, this change—of reason was conceived by the four thinkers, Garson sheds a new light on research and theory within the philosophy of madness and the philosophy of psychiatry today. He examines the question of “how is it that the mad person “has” reason, but is still not reasonable?” with the help of the four authors mentioned above (of which I discuss three).In answering this question, Garson refers specifically to my work as an example of “exactly the kind of ontology we need for rethinking madness in a positive manner—not necessarily ‘positive’ in the sense of good, helpful, or ennobling, but in the sense of going beyond a mere lack, absence, or failure.” I wholeheartedly agree with this assessment, [End Page 317] and Garson’s proposal of this tripartite schema is helpful and valuable for thinking through how we can further nourish a positive view of madness, especially with reference to Mad Pride.Locke and HeinrothGarson discusses some fragments from Locke and concludes that according to Locke “the mad person, in contrast to the idiot, possesses reason by virtue of possessing an intact inferential capacity. What ultimately makes them mad, and not reasonable, is that their premises are flawed by the unhinged power of association.” So, with Locke the capacity for inferential logic is not disturbed, and in that sense reason is intact. The unreasonable behavior would be due, according to Locke, to an unbridled increase in imagination and associations, which are taken for reality. Instead of reason the capacity to align imagination and reality is afflicted. When we translate this Lockean view into contemporary terms, we could say that it is not their cognition, their way of processing stimuli that is problematic, but their being overwhelmed by impressions or stimuli. This is akin to “bottom-up” theories: Something is wrong with perception or experience, and ‘higher’ capacities of cognition and reasoning remain intact. Reason may seem ‘perverted,’ but at a closer look, this is a result of their being victim to anomalous experience, too many stimuli or too strong imaginations.Heinroth also explicitly distinguishes madness from idiocy, that is, from a diminishment of mental capacities. Instead, he considers madness as a reaction to what Garson calls “a reality that is too awful to bear.” Madness is then “a wholesome desire of nature to cure a perversion through another perversion.” Again, madness is then not in itself a diminishment of reason, but an attempt to cure something that went wrong, in a way that is also only seemingly wrong (perverted reason). Madness then is again within reason, but this core of intact reason is... (shrink)

This paper shows the brain correlates of Cloninger’s personality model during the presentation of social scenarios under positive or negative valence situations. Social scenarios were constructed when participants played the Dictator game with two confederates that had two opposites roles as the cooperator and non-cooperator. Later the same day during a fMRI scanning session, participants read negative and positive situations that happened to confederates in the past. Participants were asked to think “how do you think those people felt during that (...) situation?” A dissimilarity matrix between stimuli were obtained from fMRI results. Results shown that Harm Avoidance trait people make use of right middle frontal gyrus and left superior frontal gyrus to discriminate between Coop and NoCoop. Cooperation as a trait makes use of the right superior temporal gyrus and the right precuneus to discriminate between Coop and NoCoop in positive social scenarios. Finally, Self-directedness trait people make use of the right inferior parietal lobe to discriminate between Coop and NoCoop in negative social scenarios and the right precuneus to discriminate between Coop and Strangers. An intuitive link between discrimination findings and behavioral patterns of those personality traits is proposed. (shrink)

In a variety of synaesthesia, photisms result from affect-laden stimuli as emotional words, or faces of familiar people. For R, who participated in this study, the sight of a familiar person triggers a mental image of "a human silhouette filled with colour". Subjective descriptions of synaesthetic experiences induced by the visual perception of people's figures and faces show similarities with the reports of those who claim to possess the ability to see the aura. It has been proposed that the (...) purported auric perception may be easily explained by the presence of a specific subtype of cross-modal perception. We analyse the subjective reports of four synaesthetes who experience colours in response to human faces and figures. These reports are compared with descriptions of alleged auric phenomena found in the literature and with claims made by experts in esoteric spheres. The discrepancies found suggest that both phenomena are phenomenologically and behaviourally dissimilar. (shrink)

Fold‐switching proteins, which remodel their secondary and tertiary structures in response to cellular stimuli, suggest a new view of protein fold space. For decades, experimental evidence has indicated that protein fold space is discrete: dissimilar folds are encoded by dissimilar amino acid sequences. Challenging this assumption, fold‐switching proteins interconnect discrete groups of dissimilar protein folds, making protein fold space fluid. Three recent observations support the concept of fluid fold space: (1) some amino acid sequences interconvert between (...) folds with distinct secondary structures, (2) some naturally occurring sequences have switched folds by stepwise mutation, and (3) fold switching is evolutionarily selected and likely confers advantage. These observations indicate that minor amino acid sequence modifications can transform protein structure and function. Consequently, proteomic structural and functional diversity may be expanded by alternative splicing, small nucleotide polymorphisms, post‐translational modifications, and modified translation rates.

In this paper, we delimit the moments in which, in “Doctrine of the Similar” and in “On the Mimetic Faculty”, reading and Sprache (speech, language, language) are inseparably linked to the category of “non-sensuous similarities.” In this conception, the analogical-proportional representation of traditional mimesis is dislocated by a rhetori- cal conception of symbolic experiences given by different semiotic forms. Moreover, the idealist ground of the symbolic is relocated in the specific area of language, in which the perception of similarities is (...) mediated by the instance of reading under the predominance of the dissimilar. Our fundamental purpose resides in exposing how this production of similarities, in contrast to those of the relational schematism of classical logicism and with the ground of idealistic determination of Kantian aesthetics, shows its paradoxical grounds in the mimetic reading.

Synesthetes can be distinguished from nonsynesthetes on a variety of experimental tasks because their concurrent synesthetic experiences can affect task performance if these experiences match or conflict with some aspect of the stimulus. Here, we tested grapheme‐color synesthetes and nonsynesthetic control participants using a novel perceptual similarity task to assess whether synesthetes’ concurrent color experiences influence perceived grapheme similarity. Participants iteratively arranged graphemes and, separately, their associated synesthetic colors in a display, such that similar items were placed close together and (...) dissimilar items further apart. The resulting relative inter‐item distances were used to calculate the pair‐wise (dis)similarity between items in the set, and thence to create separate perceptual representational dissimilarity matrices (RDMs) for graphemes and colors, on an individual basis. On the assumption that synesthetes’ similarity judgments for graphemes would be influenced by their concurrent color experiences, we predicted that grapheme and color RDMs would be more strongly correlated for synesthetes than nonsynesthetes. We found that the mean grapheme‐color RDM correlation was indeed significantly higher in synesthetes than nonsynesthetes; in addition, synesthetes’ grapheme‐color RDM correlations were more likely to be individually statistically significant, even after correction for multiple tests, than those of nonsynesthetes. Importantly, synesthetes’ grapheme‐color RDM correlations scaled with the consistency of their grapheme‐color associations as measured by their Synesthesia Battery (SB) scores. By contrast, the relationship between SB scores and grapheme‐color RDM correlations for nonsynesthetes was not significant. Thus, dissimilarity analysis quantitatively distinguished synesthetes from nonsynesthetes, in a way that meaningfully reflects a key aspect of synesthetic experience. (shrink)

In Nicomachean Ethics II 4 Aristotle famously raises a puzzle concerning moral habituation, and he seems to dissolve it by recourse to the analogy between moral virtue and skills. A new interpretation of the chapter is offered on the basis of an important evaluative dissimilarity then noted by Aristotle, one almost universally disregarded by interpreters of the chapter. I elucidate the nature of the dissimilarity in question and argue for its paramount importance for understanding Aristotle’s conception of moral agency. I (...) also show that it is the particularly intricate and puzzling character of the chapter that has prevented scholars from noticing such a dissimilarity and from integrating it to the interpretation of the chapter.

This paper considers whether an analogy between distance and dissimilarlity supports the thesis that degree of dissimilarity is distance in a metric space. A straightforward way to justify the thesis would be to define degree of dissimilarity as a function of number of properties in common and not in common. But, infamously, this approach has problems with infinity. An alternative approach would be to prove representation and uniqueness theorems, according to which if comparative dissimilarity meets certain qualitative conditions, then it (...) is representable by distance in a metric space. I will argue that this approach faces equally severe problems with infinity. (shrink)

Although analogical reasoning has long been a popular method of reasoning in bioethics, current literature does not sufficiently grasp its variety. We assert that the main shortcoming is the fact that an analogy's value is often judged on the extent of similarity between the source situation and the target situation, while in (bio)ethics, analogies are often used because of certain dissimilarities rather than in spite of them. We make a clear distinction between dissimilarities that aim to reinforce a similar approach (...) in the source situation and the target situation and dissimilarities that aim to undermine or denounce a similar approach. The former kind of dissimilarity offers the analogy more normative force than if there were no dissimilarities present; this is often overlooked by authors who regard all relevant dissimilarities as detrimental to the analogy's strength. Another observation is that an evaluation of the normative force of an analogy cannot be made independently of moral principles or theories. Without these, one cannot select which elements in an analogy are morally relevant nor determine how they should be interpreted. (shrink)

In this essay, I examine the role of dissimilarity in scientific representation. After briefly reviewing some of the philosophical literature which places a strong emphasis on the role of similarity, I turn to examine some work from Carroll and Borges which demonstrates that perfect similarity is not valuable in the representational use of maps. Expanding on this insight, I go on to argue that this shows that dissimilarity is an important part of the representational use of maps—a point I then (...) extend to the case of scientific representation. Relying on some work from Latour, I argue that dissimilarity plays an essential role in representational practice, by providing novel forms of manipulation and use which affords the achievement of various epistemic and nonepistemic aims. After showing how this point connects to some other literature on scientific representation, I discuss some examples of the value of dissimilarity in the use of representational vehicles. Overall, I argue that to understand scientific representation, we will need to consider more than just similarity. We will need to explore dissimilarities as well. (shrink)

It has become customary in modern behavioristics to speak of stimuli as though they elicit responses from organisms. But logically this is absurd, for analysis of the grammatical roles of stimulus and response concepts shows that stimuli and responses differ in logical type from causes and effects. The "S elicits R" formula thus stands revealed as elliptical for a more complicated form of assertion. The trouble with this ellipsis, however, is that by suppressing vital components of formal structure (...) in behavioral principles, it has led to gratuitous assumptions about the environmental antecedents of behavior and seriously undermined the ability of behavior theory to assimilate the "higher mental processes.".

Second-order arithmetic and class theory are second-order theories of mathematical subjects of foundational importance, namely, arithmetic and set theory. Despite the similarity in appearance, there turned out to be significant mathematical dissimilarities between them. The present paper studies various principles in class theory, from such a comparative perspective between second-order arithmetic and class theory, and presents a few new dissimilarities between them.

The anchoring effect is a form of cognitive bias in which exposure to some piece of information affects its subsequent numerical estimation. Previous studies have discussed which stimuli, such as numbers or semantic priming stimuli, are most likely to induce anchoring effects. However, it has not been determined whether anchoring effects will occur when a number is presented alone or when the semantic priming stimuli have an equivalent dimension between a target and the stimuli without a (...) number. We conducted five experimental studies using stimuli to induce anchoring effects. We found that anchoring effects did not occur when a number was presented alone or when phrases to induce semantic priming were used without presenting a number. These results indicate that both numerical and semantic priming stimuli must be presented for anchoring effects to occur. Our findings represent a substantial contribution to the literature on anchoring effects by offering insights into how these effects are generated. (shrink)

Transient changes in DNA torsional tension are generated by environmental stimuli and transcriptional activity. In eukaryotic cells, these changes can only be accommodated by a chromatin structure that is flexible. This property of chromatin may be essential to the regulation of eukaryotic gene activity.

The symbolic world of Corpus Areopagiticum is considered here from the prospect of the dichotomy in similar and dissimilar similarity (the images). The dissimilar images are divided into decent, average andthe distant ones. The similarand dissimilar images of Areopagite describe the world system by cataphatic and apophatic approach. The apophatic one seems to be noticeably more important for the author, as in denial (what God is not) or as in applying of unworthy predicates concerning him, his fundamental (...) transcendence and unknowability become more expressive. Similarand dissimilar images are both the divine names from the NewTestament and the Old Testament respectively. They allow the agent of cognition get closer to the understanding of the universe structure. The divine names correspond to the so-called universal concepts which are considered in the works of contemporary linguistic conceptualistics. Anthropomorphic and zoomorphic characters of the Scripture belong to the dissimilar images, such as parts of the human body, wild animals etc. The most distant dissimilar images should be analyzed as the manifestations of the human passions applied to the naming or description of God. This is the most controversial aspect of the dissimilar similarities because of their provocative character for a profane reader. Thomas Aquinas, one of the ardent admirers of the Corpus, has denied it while considering the theory of images ("The Mystical Theology"). The works of Areopagite have become an example of combining the Eastern and Western traditions ofargumentation which still remains within the framework of the Christian experience. (shrink)

Upon consideration of the unconditioned and particularly the conditioned stimuli that have been proposed to participate in the generation of incentive motivational states and, by extension, of extraversion, the nature of the contribution of NAS DA becomes less clear.

How might such stimuli affect the ability of experience-dependent processes to introduce stable individual differences in the development and expression of extraversion trait (...) levels? (shrink)

Recently there has been a great deal of argument about what justifies references to representational states in explanations of behavior. I discuss Jerry Fodor's claim that it is necessary to ascribe representational states to organisms that respond to "nonnomic properties" of stimuli. Zenon Pylyshyn's (apparently equivalent) claim that it is necessary to ascribe representational states to organisms that respond to "nonprojectable properties" of stimuli and Fodor's claim that an organism's ability to respond to nonnomic properties of stimuli (...) is a criterion of its having representational states. I argue that if Fodor's account of how organisms respond to nonnomic properties of stimuli is correct, we could always replace explanations that appeal to nonnomic properties of stimuli with explanations that appeal only to nomic properties of stimuli. I also argue that, according to Fodor's account, we could not determine whether an organism is responding to nonnomic properties of stimuli unless we already knew whether the explanation of the response includes a reference to a representational state. Thus, given Fodor's account, there is no noncircular way of arguing that it is necessary to ascribe representational states to organisms because they respond to nonnomic properties of stimuli. Finally, I argue that Fodor has not actually provided an account of how organisms respond to nonnomic properties of stimuli and I discuss the prospects of a different strategy for linking the nonnomic properties of stimuli to representational states.
