What the experimenter’s prime tells the observer’s brain

The presentation of a stimulus below the threshold of conscious awareness can exert an influence on the processing of a subsequent target. One such consequence of briefly presented “primes” is seen in the negative compatibility effect. The response time (RT) to determine the left—right orientation of an arrow (i.e., the target) is relatively slow if a prime is also an arrow whose direction corresponds to that of the target. When the direction of the arrow is opposite that of the prime, RTs are relatively fast. In four experiments, we examined whether the prime shifts attention from the location of the subsequent target and whether this attention shift influences target processing. Results showed that the prime does indeed move attention. The consequence of this attention movement is that the representation of direction is affected. Specifically, RTs to process an arrow are shorter if the arrow’s direction is compatible with the last shift of attention. Furthermore, this interference occurs at a conceptual level concerning the representation of left and right rather than at the motor planning level. We argue that a shift in attention brought about by the prime can create a negative compatibility-like effect.     

Intervening in the psychopath’s brain

Psychopathy is a disorder involving personality and behavioral features associated with a high rate of violent aggression and recidivism. This paper explores potential psychopharmacological therapies to modulate dysfunctional neural pathways in psychopaths and reduce the incidence of their harmful behavior, as well as the ethical and legal implications of offering these therapies as an alternative to incarceration. It also considers whether forced psychopharmacological intervention in adults and children with psychopathic traits manifesting in violent behavior can be justified. More generally, the paper addresses the question of how to weigh the psychopath’s presumptive right to non-interference in his brain and mind against the public interest in avoiding harm.     

Hong Kong’s Umbrella Movement and the promotion of deviance

ABSTRACT

As a social movement demanding universal suffrage, Hong Kong’s Umbrella Movement mobilized thousands of young protesters and fomented radical views stridently subversive of mainland China’s political interference. The social movement continues to promote further forms of deviance in the form of calling for independence. As the city and former British colony lacks the sovereignty of statehood and democracy, the movement’s non-conformity to law needs to be contextualized as a form of deviance. In contributing to the deviancy of social movements, we utilize data obtained from interviews with participants of the movement alongside those who opposed the protest to understand the East Asian cultural setting of the Umbrella Movement’s promotion of deviance.     

What the reader’s eye tells the mind’s ear: Silent reading activates inner speech

Although copious research has investigated the role of phonology in reading, little research has investigated the precise nature of the entailed speech representations. The present study examined the similarity of “inner speech” in reading to overt speech. Two lexical decision experiments (in which participants gave speeded word/nonword classifications to letter strings) assessed the effects of implicit variations in vowel and word-initial consonant length. Responses were generally slower for phonetically long stimuli than for phonetically short stimuli, despite equal orthographic lengths. Moreover, the phonetic length effects displayed principled interactions with common factors known to affect lexical decisions, such as word frequency and the similarity of words to nonwords. Both phonetic length effects were stronger among slower readers. The data suggest that acoustic representations activated in silent reading are best characterized as inner speech rather than as abstract phonological codes.     

Havighurst’s Social Roles Revisited

The purpose of this exploratory research was to review, update, and revise Havighurst’s classic social role studies for their relevance in contemporary society. Based on the input of expert panels, 13 roles, Association/Club Member, Citizen, Daughter/Son, Friend, Grandparent, Home/Services Manager, Kin/Relative, Learner, Leisure Time Consumer, Parent, Religious Affiliate, Spouse/Partner, and Worker, were incorporated into an instrument to assess social role importance. The instrument was administered to a stratified, quota sample of 300 respondents. Univariate repeated-measures analysis and Dunn’s test for multiple comparisons were conducted. Perceived social role importance ratings were established for age, gender, and socio-economic status (SES) groupings. The Friend role and a cluster of family-associated roles received the highest overall ratings. Many roles appeared to have a distinct age-related factor. SES differences, particularly among the lowest level, were also significant in many roles.     

Neuromythology of Einstein’s brain

The idea that the brain of the great physicist Albert Einstein is different from “average” brains in both cellular structure and external shape is widespread. This belief is based on several studies examining Einstein’s brain both histologically and morphologically. This paper reviews these studies and finds them wanting. Their results do not, in fact, provide support for the claim that the structure of Einstein’s brain reflects his intellectual abilities.     

Dewey’s Social Ontology: A Pragmatist Alternative to Searle’s Approach to Social Reality

Dewey’s social ontology could be characterized as a habit ontology, an ontology of habit qua second nature that offers us an account of intentionality, social statuses, institutions and norms in terms of habituations. Such an account offers us a promising alternative to contemporary intentionalist and deontic approaches to social ontology such as Searle’s. Furthermore, it could be the basis of a social ontology better suited to explain both the maintenance and the transformation of social reality.     

On the Very Idea of Social Construction: Deconstructing Searle’s and Hacking’s Critical Reflections

The starting point of the following inquiry addresses John Searle’s and Ian Hacking’s most prominent critique of contemporary “constructionism” in the 1990s. It is stimulated by the astonishing fact that neither Hacking nor Searle take into account Peter Berger’s and Thomas Luckmann’s classical essay and sociological masterpiece The Social Construction of Reality in their contributions. Critically revisiting Searle’s and Hacking’s critique on the so-called constructivist approach, the article demonstrates that both authors have failed to put forth a sociologically valid understanding of the approach in question. The following analysis aims to deconstruct the conceptualizations offered by Searle and Hacking, and to reconstruct and defend the original sense of the term “social construction” as most prominently introduced by Berger and Luckmann to sociology, and social sciences in general.     

Using an AI creativity system to explore how aesthetic experiences are processed along the brain’s perceptual neural pathways

With the increased sophistication of AI techniques, the application of these systems has been expanding to ever newer fields. Increasingly, these systems are being used in modeling of human aesthetics and creativity, e.g. how humans create artworks and design products. Our lab has developed one such AI creativity deep learning system that can be used to create artworks in the form of images and videos. In this paper, we describe this system and its use in studying the human visual system and the formation of aesthetic experiences. Specifically, we show how time-based AI created media can be used to explore the nature of the dual-pathway neuro-architecture of the human visual system and how this relates to higher cognitive judgments such as aesthetic experiences that rely on these divergent information streams. We propose a theoretical framework for how the movement within percepts such as video clips, causes the engagement of reflexive attention and a subsequent focus on visual information that are primarily processed via the dorsal stream, thereby modulating aesthetic experiences that rely on information relayed via the ventral stream. We outline our recent study in support of our proposed framework, which serves as the first study that investigates the relationship between the two visual streams and aesthetic experiences.     

All Justice is Social but it’s not all Social Justice

I take social injustice to be injustice perpetrated on members of society by laws and public social practices. I take social justice to be the struggle to right social injustice. After explaining these ideas, I then address the question: why are so many people opposed to the very idea of social justice? I offer a number of explanations, among them, that to acknowledge that there is social injustice in one’s society often requires considerable change on one’s part.     

Social processes affecting the mnemonic consequences of rumors on children’s memory

This research examined whether the impact of overheard rumors on children’s memory for their experiences varies as a function of social processes. The results of two experiments revealed that the very same errant rumor had different consequences for children’s recollections depending on the degree and type of social interactions they had with peers after exposure to the rumor. In both experiments, 3- to 5-year-olds overheard a false rumor about a recently experienced event and then were interviewed about the event 1 week later. In Experiment 1, children were more likely to report experiencing rumored-but-nonoccurring information if they were allowed to interact naturally with peers following exposure to the rumor than if they were prevented from peer exchange. In Experiment 2, exposure to the rumor induced greater memory contamination if it was planted among familiar peers than if it was encountered among strangers.     

Relevance of the listener’s motor system in recalling phrases enacted by the speaker

Memory for series of action phrases improves in listeners when speakers accompany each phrase with congruent gestures compared to when speakers stay still. Studies reveal that the listeners’ motor system, at encoding, plays a crucial role in this enactment effect. We present two experiments on gesture observation, which explored the role of the listeners’ motor system at recall. The participants listened to the phrases uttered by a speaker in two conditions in each experiment. In the gesture condition, the speaker uttered the phrases with accompanying congruent gestures, and in the no-gesture condition, the speaker stayed still while uttering the phrases. The participants were then invited, in both conditions of the experiments, to perform a motor task while recalling the phrases proffered by the speaker. The results revealed that the advantage of observing gestures on memory disappears if the listeners move at recall arms and hands (same motor effectors moved by the speaker, Experiment 1a), but not when the listeners move legs and feet (different motor effectors from those moved by the speaker, Experiment 1b). The results suggest that the listeners’ motor system is involved not only during the encoding of action phrases uttered by a speaker but also when recalling these phrases during retrieval.     

Type and Spontaneity: Beyond Alfred Schutz’s Theory of the Social World

Alfred Schutz’s theory of the social world, often neglected in philosophy, has the potential to capture the interplay of identity and difference which shapes our action, interaction, and experience in everyday life. Compared to still dominant identity-based models such as that of Jürgen Habermas, who assumes a coordination of meaning built on the idealisation of stable rules (primarily those of language), Schutz’s theory is an important step forward. However, his central notion of a “type” runs into a difficulty which requires constructive criticism. Against the background of Schutz’s theory of meaning inspired by Bergson and Husserl, his idea of types “taken for granted until further notice” is shown to express a primacy of identity which, in the final analysis, leads into the implausible scenario of ‘ubiquitous tunnel vision’. This makes it necessary to go beyond Schutz and assume an inherently motivated tendency towards difference in meaning termed ‘spontaneity’. Where spontaneity and the opposed tendency towards identity of meaning work together in the application of types, they enable embodied subjects to interact with the world and with each other in the routine yet flexible and sometimes innovative ways which we all know.     

Social Media’s Influence on Business-to-Business Sales Performance

The implementation of social media technology in a firm’s marketing strategy has been adopted by some forward-thinking sales forces. Sharing content and building a network of contacts are the principles behind social media. The utilization of social media (e.g., LinkedIn and Twitter) for reaching business-to-business clients is a relatively new phenomenon with performance outcomes essentially unknown. Data were collected from 1,699 business-to-business salespeople from over 25 different industries. Using structural equation modeling, the findings support that social media has a positive relationship with sales processes (creating opportunities and relationship management) and relationship sales performance.     

Minds at rest? Social cognition as the default mode of cognizing and its putative relationship to the "default system" of the brain

The “default system” of the brain has been described as a set of regions which are ‘activated’ during rest and ‘deactivated’ during cognitively effortful tasks. To investigate the reliability of task-related deactivations, we performed a meta-analysis across 12 fMRI studies. Our results replicate previous findings by implicating medial frontal and parietal brain regions as part of the “default system”.However, the cognitive correlates of these deactivations remain unclear. In light of the importance of social cognitive abilities for human beings and their propensity to engage in such activities, we relate our results to findings from neuroimaging studies of social cognition. This demonstrates a remarkable overlap between the brain regions typically involved in social cognitive processes and the “default system”.We, henceforth, suggest that the physiological ‘baseline’ of the brain is intimately linked to a psychological ‘baseline’: human beings have a predisposition for social cognition as the default mode of cognizing which is implemented in the robust pattern of intrinsic brain activity known as the “default system”.     

Subjectively different emotional schematic faces not automatically discriminated from the brain’s bioelectrical responses

The present study investigates how the brain automatically discriminates emotional schematic faces, as indicated by the mismatch responses, and how reliable these brain responses are. Thirty-three healthy volunteers participated in the vMMN EEG experiment with four experimental sets differing from each other by the type of standard (object with scrambled face features) and the type of deviants (Angry, Happy and Neutral schematic faces) presented. Conscious subjective evaluations of valence, arousal and attention catching of the same stimuli showed clear differentiation of emotional expressions. Deviant faces elicited rather similar vMMN at frontal and occipital sites. Bayesian analyses suggest that vMMN does not differ between angry and happy faces. Neutral faces, however, did not yield statistically significant vMMN at occipital leads. Pearson’s correlation and intra-class correlation analyses showed that the brain’s reactions to the stimuli were highly stable within individuals across the experimental sets, whereas the mismatch responses were much more variable.
