I did not expect to be dreaming: Explaining realization in lucid dreams with a Bayesian framework

The commonsense view is that a lucid dream starts when the dreamer realizes that they are currently dreaming. The notion of realization, however, has been accepted at face value, with little consideration of whether the dreamer realizes that they are dreaming in the sense of actual reasoning, or if it is a mere epiphenomenon of lucid dream initiation. This article offers a solution to this problem by, first, arguing that the transition to lucidity can occur as a result of successful reasoning, and second, building a model of this reasoning in terms of probabilistic reasoning. The established Bayesian model explains realization in lucid dreams taking under consideration two factors: the beliefs that the dreamer holds on what is generally probable and improbable, and the dreamer’s admissibility of being in a dream. Defended against important objections, the model offers an explanation of lucid dream initiation, relevant for future research on dreaming.     

Direct social perception of others’ subjective time

In this paper, I deploy Gallagher et al.’s theory of Direct Social Perception (DSP) to help explain how we perceive others’ subjective time. This process of second-person temporal perception plays an important role in interpersonal interaction, yet is often glossed over in discussions of intersubjectivity. Using A.D. Craig (2009) ‘awareness’ model of subjective time to unify converging evidence that subjective time is embodied, affective, and situated, I argue that subjective time cannot be considered as a hidden or invisible aspect of a private mind, but is partially externally visible through our gestures, expressions, and other behaviours as they unfold within a particular context. My central thesis is that, in face to face interactions, we are able to directly perceive these visible components of other people’s subjective time. This is made possible by our “enculturated” (Menary, 2015) and enactive perceptual faculties. The process of social perception is not a passive, unidirectional affair where static information about one person’s subjective time is transmitted to the other, but rather inextricably linked with action (both at the personal and subpersonal level) and interaction effects produced by a dynamic coupling between participants. Such an enactive perspective reveals how others’ subjective time can be perceived in everyday interactions.     

空间交互研究新视角：多重社会因素的影响

空间交互是人类生存和社交的重要内容, 主要包括语言交流和视角采择两大范畴。对空间交互策略和效率的影响因素的研究, 传统上集中于空间因素, 近年来逐渐开始关注各种社会因素, 包括个体自身的社会认知特质、交互对象的社会属性和空间环境中的社会线索, 并从不同角度提出了理论解释。未来研究应关注社会认知与空间认知的跨领域融合, 考察更加多元的空间交互对象, 最终建立一个整合空间和社会因素的空间交互理论框架。     

Social competence in early childhood: An empirical validation of the SOCIAL model

Social skills are the basis of human interactions and functioning in society. Social competence (SC) is thought to evolve gradually during childhood and adolescence via the interplay of multiple factors. In particular, the early years of life are marked by the emergence of basic social abilities and constitute the foundation for successful social development. The biopsychosocial SOcio-Cognitive Integration of Abilities modeL (SOCIAL) posits that internal (child-based), external (environment), and cognitive factors are critical to SC in the context of normal brain maturation; but this has yet to be shown empirically and comprehensively. This study tested the SOCIAL model in a sample of typically developing preschool children. Parents of 103 children (M = 67.59 months, SD = 11.65) completed questionnaires and children underwent neuropsychological assessment of executive functioning (EF), communication skills and social cognition. Three-step hierarchical regression analyses (1) Internal factors, 2) External factors, 3) Cognitive factors) confirmed that each step of the regression model significantly predicted SC. In the final model, general cognitive and socio-cognitive factors significantly predicted SC above and beyond internal and external factors: children with lower temperamental negative affect and less parent-reported executive dysfunction, as well as better non-verbal communication and theory of mind had better SC. Our findings support the conceptual SOCIAL model, and highlight the importance of internal, external, and cognitive factors for SC in the preschool years. Identification of factors associated with early social development can inform both normative and clinical approaches to identifying intervention loci and optimizing SC in those at risk for maladaptive social functioning.     

Multiple sclerosis,emotion perception and social functioning

People with multiple sclerosis (MS) can experience problems in interpreting others’ emotions from faces or voices. However, to date little is known about whether difficulties in emotion perception in MS are related to broader aspects of social functioning. Also, there are few studies reporting the effect of MS on more ecologically valid assessments of emotion perception using multimodal videos. The current study looks at (1) the effect of MS on perceiving emotions from faces, voices and multimodal videos; (2) the possible role of slowed processing and executive dysfunction in emotion perception problems in MS and (3) the relationship between emotion perception and broader social functioning in MS. 53 people with MS and 31 healthy controls completed tasks of emotion perception and cognition, and assessed their levels of social support and social participation. Participants with MS performed worse than demographically matched controls on all measures of emotion perception. Emotion perception performance was related to cognitive measures in those with MS. Also, significant associations were found between emotion perception difficulties in MS and poorer social function. In particular, people with MS who had poorer emotion perception also reported lower levels of social support from their friends, and regression analysis showed that this prediction was maintained even when disease severity and cognitive function were taken into account. These results show that problems with emotion perception in MS extend to more realistic tasks and may predict key aspects of social functioning.     

Taxonomies of aggressive behavior: A preliminary report

It has been widely and regularly suggested that aggression is not a unitary concept but rather an omnibus term concealing important and distinct subclasses of behavior. Psychologists have offered various categorical schemes highlighting motivation and form as distinguishing criteria. Many writers have also noted the social relativity of dermitions of classes of aggression and called for a consideration of lay conceptions of aggressive behavior. The present paper explores the correspondence between psychologists' and laypersons' categorizations of aggressive acts. Ten short scenarios of aggression were generated to embody systematic permutations of form and motive as suggested by the published work of social psychologists. Subjects rated every pairwise combination in terms of perceived similarity. The data were subjected to three-factor, multidimensional scaling. The resulting structure indicated that subjects' ratings were not random and reflected consideration of motive (hostile, normative, instrumental, status) and of direct versus indirect form. The data were thus in close correspondence with the classifications generated by psychologists. The desirability of refining this technique and extending it to other cultural and subcultural groups is discussed.     

Person perception when aggressive or nonaggressive sports are primed

Previous research investigating the factors contributing to sports spectator violence has focused primarily on conscious processes such as the disinhibiting effects of aggressive models and physiological arousal. The current research borrows a methodology from social cognition work to examine the role of passive, category accessibility effects on fan hostility. Prior research has indicated that as a schema becomes more accessible in memory, the use of it to encode subsequent information is increased. It was therefore hypothesized that individuals for whom the category of hostility had been unobtrusively primed with aggressive-sports names (e.g., boxing) would rate an ambiguous target person as more hostile and as more likely to prefer hostile activities relative to persons who were primed with sports names which were not associated with violence (e.g., golf). The results supported the hypotheses, with subjects who were primed with aggressive-sports rating an unrelated target person's behavior as significantly more hostile and as more likely to prefer aggressive activities relative to subjects exposed to sentences containing references to nonaggressive-sports. Discussion includes the potential ramifications for spectator aggression at sporting events.     

Too exhausted to go to bed: Implicit theories about willpower and stress predict bedtime procrastination

While most people are aware of the importance of sleep for their health, well-being, and performance, bedtime procrastination is a pervasive phenomenon that can be conceptualized as a case of self-control failure (Kroese et al., Frontiers in Psychology, 5, 2014, 1). Two daily diary studies (N₁ = 185, N₂ = 137) investigated beliefs about willpower and stress as interactive predictors of bedtime procrastination. Beliefs about willpower capture whether people think of their willpower as limited resource that gets easily depleted (limited theory) or as something that remains regardless of previous acts of self-control (non-limited theory). Results show that after a stressful day, people with a limited versus non-limited theory procrastinate more on going to bed, while there is no difference in bedtime procrastination on less stressful days. Thus, ironically, limited theorists who should be more concerned with recovering their resources after a stressful day sleep less the following night.     

Geographic patterns of implicit age bias and associations with state-level health outcomes across the United States

Negative attitudes toward aging are pervasive in society and may be detrimental to people's health as they become older. Older people tend to report feeling significantly younger than their chronological age, often as a way of psychologically distancing themselves from the stigma of old age. However, attitudes and behaviors toward aging may differ across regional contexts. We examined associations among state-level patterns of bias against older adults and state-level health outcomes across the United States. Data from 803,009 respondents (ages: 15–94) across 50 U.S. states (and the District of Columbia) revealed geographic variation in implicit age bias. Higher state-level implicit age bias was associated with poorer state-level health outcomes among adults ages 65+. Older adults living in states high in implicit age bias showed greater age-group dissociation compared to older adults living in states low in implicit age bias. Findings highlight potential consequences of implicit age bias and invite further research on the long-term health implications of individual age-group dissociation in response to regional age bias.
