The ascription of mind to others is central to social cognition. Most research on the ascription of mind has focused on motivated, top-down processes. The current work provides novel evidence that facial width-to-height ratio (fWHR) serves as a bottom-up perceptual signal of humanness. Using a range of well-validated operational definitions of humanness, we provide evidence across five studies that target faces with relatively greater fWHR are seen as less than fully human compared to their relatively lower fWHR counterparts. We then present two ancillary studies exploring whether the fWHR-to-humanness link is mediated by previously established fWHR-trait links in the literature. Finally, three additional studies extend this fWHR-humanness link beyond measurements of humanness, demonstrating that the fWHR-humanness link has consequences for downstream social judgments including the sorts of crimes people are perceived to be guilty of and the social tasks for which they seem helpful. In short, we provide evidence for the hypothesis that individuals with relatively greater facial width-to-height ratio are routinely denied sophisticated, humanlike minds.

This chapter refers to the beliefs of individuals that occupied various positions in the structures of the old regime. For histoire des mentalités, the chapter tries to determine popular beliefs, elite beliefs, and beliefs about beliefs in accordance with reasons given in the Madisonian caveats. It also analyzes the behavior of the main agents in the economic and political system, which includes the peasantry, local authorities, several urban groupings, the parlements, provincial estates, the royal administration, the royal court, and the king himself. It includes the top-down beliefs of the authorities about their subjects and the bottom-up beliefs of the subjects about the authorities. This chapter also describes beliefs of the members of any group in the social hierarchy about other members of the same group.

The concept of living technology—that is, technology that is based on the powerful core features of life—is explained and illustrated with examples from artificial life software, reconfigurable and evolvable hardware, autonomously self-reproducing robots, chemical protocells, and hybrid electronic-chemical systems. We define primary (secondary) living technology according as key material components and core systems are not (are) derived from living organisms. Primary living technology is currently emerging, distinctive, and potentially powerful, motivating this review. We trace living technology's connections with artificial life (soft, hard, and wet), synthetic biology (top-down and bottom-up), and the convergence of nano-, bio-, information, and cognitive (NBIC) technologies. We end with a brief look at the social and ethical questions generated by the prospect of living technology.

I defend the case for an evolutionary theory of schizophrenia and the social brain, arguing that such an exercise necessitates a broader methodology than that familiar to neuroscience. I propose a reworked evolutionary genetic model of schizophrenia, drawing on insights from commentators, buttressing my claim that psychosis is a costly consequence of sophisticated social cognition in humans. Expanded models of social brain anatomy and the spectrum of psychopathologies are presented in terms of upper and lower social brain and top-down and bottom-up processes. Finally, I argue that cerebral asymmetry evolved as an emergent property of primary intrahemispheric reorganisation in hominoids.

Recent advances in cognitive neurosciences compellingly suggest that the human brain does not have a single cognitive system, but two parallel cognitive systems. These two systems normally blend more or less perfectly in the human mind. Only the failure of one reveals the existence of the other in a way that would otherwise be difficult to discern. This research has established that “human beings have evolved two parallel ways of thinking. One, which you might call people-thinking, mentalistic cognition – or more simply mentalism – is wholly concerned with understanding human beings, their minds, motives, and emotions; the other, which by contrast you could call things-thinking or mechanistic cognition, is concerned with understanding and interacting with the physical, non-human universe of inert objects“.In other words, the social brain works entirely differently from mechanistic thinking, using altogether different neural pathways. The current view in the cognitive sciences supports the dual process theory that distinguishes between analytical and intuitive styles of information processing. These two styles – analytical and intuitive – broadly correspond to mechanistic and mentalistic cognition modes. Analytical processing involves abstract, rule-based, logical and deliberate thought, whereas the intuitive style is implicit and contextualized, taking advantage of associations.These two styles can be viewed as the polar ends of a single continuum, best understood as processing modes which individuals move in and out of in a continuous manner, depending on the situational dynamics.However, these two cognitive styles can become the preferences for cognition and learning if one prevails over the other.The general discussions on higher cognitive processes usually do not cite evidence from the studies of clinical population groups. In my view, such discussions are necessary. In a clinical condition, the cognitive preference inevitably becomes a bias, even a strong bias for thinking and behaviour. The clinical conditions have genetic and epigenetic causes, even if these are only partly known. According to the Extreme Male Brain theory explaining autism, the continuum of cognitive capabilities extends between the natural faculties of empathizing and systemizing in the human brain.In neuroscience studies, the term anti-correlated networks of the brain has been coined to describe the phenomenon of alternating activation, in which mechanical tasks were able to deactivate the regions associated with social reasoning, and social tasks deactivated the regions associated with mechanical reasoning.The first mode of thinking is mechanistic and operates in a more bottom-up manner, being highly sensitive to the type of stimulus. However, the mentalizing system is more top-down, and is influenced by the cognitive context and much less by the surface characteristics of stimuli.The Imprinted Brain Theory describes the diametrical model of the social brain connecting the two cognition modes with mental illnesses. This model establishes a continuum of the intellectual capabilities of the social brain, extending from high mentalism in the psychotic spectrum to low mentalism in autistic spectrum conditions. Accordingly, human talents can be divided into two large groups – these with excellent people skills and those with elevated mechanistic skills. Because of anti-correlation, both groups have deficiencies in the respective opposite domain. Autistic savantism is an example of elevated mechanistic and less than average mentalistic capabilities. The imprinted brain theory suggests that a reversed pattern of elevated mentalistic talent with reduced mechanistic abilities is found in psychotic savantism, a previously unsuspected condition.The mentalistic kind of knowledge tends to be ideological, contextual, holistic, top-down, centrally coherent and globally connected. Mechanistic thinking is wired to find insights and patterns on the local level, and tends to be non-contextual, reductionist, bottom-up, and noncentrally coherent. Numerous clinical studies have shown an increased local processing style in autistic spectrum conditions, whereas the psychotic spectrum exhibits an increased global processing bias. The global style has an advantage in social tasks and the local processing bias in mechanistic tasks. A genius is someone who has elevated levels of talent in both modes of thinking.

While many phonological patterns target classes of sounds that can be defined phonetically, a large number of patterns in descriptive grammars involve sounds that cannot be easily characterised in phonetic terms. This finding suggests that phonological patterns themselves must be taken into account when learning phonological representations, and that phonological classes may emerge in learning from both phonetic factors (bottom-up) and phonological patterns (top-down). The current work presents a case of a phonetically unnatural class in South Bolivian Quechua that is active in the phonology of the language, and provides experimental support that this class is referred to by speakers’ grammars. While many cases of phonetically unnatural classes have been documented in descriptions of language patterns, in most cases there is little or no evidence that these patterns or classes are represented by speakers as they are described by linguists.

We propose a social model of spontaneous self-organization generating criticality and resilience, called Self-Organized Temporal Criticality (SOTC). The criticality-induced long-range correlation favors the societal benefit and can be interpreted as the social system becoming cognizant of the fact that altruism generates societal benefit. We show that when the spontaneous bottom-up emergence of altruism is replaced by a top-down process, mimicking the leadership of an elite, the crucial events favoring the system’s resilience are turned into collapses, corresponding to the falls of the leading elites. We also show with numerical simulation that the top-down SOTC lacks the resilience of the bottom-up SOTC. We propose this theoretical model to contribute to the mathematical foundation of theoretical sociology illustrated in 1901 by Pareto to explain the rise and fall of elites.

The respective roles of the neuropeptides arginine vasopressin (AVP) and oxytocin (OXT) in modulating social cognition and for therapeutic intervention in autism spectrum disorder have not been fully established. In particular, while numerous studies have demonstrated effects of oxytocin in promoting social attention the role of AVP has not been examined. The present study employed a randomized, double-blind, placebo (PLC)-controlled between-subject design to explore the social- and emotion-specific effects of AVP on both bottom-up and top-down attention processing with a validated emotional anti-saccade eye-tracking paradigm in 80 male subjects (PLC = 40, AVP = 40). Our findings showed that AVP increased the error rate for social (angry, fearful, happy, neutral and sad faces) but not non-social (oval shapes) stimuli during the anti-saccade condition and reduced error rates in the pro-saccade condition. Comparison of these findings with a previous study (sample size: PLC = 33, OXT = 33) using intranasal oxytocin revealed similar effects of the two peptides on anti-saccade errors but a significantly greater effect of AVP on pro-saccades. Both peptides also produced a post-task anxiolytic effect by reducing state anxiety. Together these findings suggested that both AVP and OXT decrease goal-directed top-down attention control to social salient stimuli but that AVP more potently increased bottom-up social attentional processing.
