Trust and the value of overconfidence: a Bayesian perspective on social network communication

The paper presents and defends a Bayesian theory of trust in social networks. In the first part of the paper, we provide justifications for the basic assumptions behind the model, and we give reasons for thinking that the model has plausible consequences for certain kinds of communication. In the second part of the paper we investigate the phenomenon of overconfidence. Many psychological studies have found that people think they are more reliable than they actually are. Using a simulation environment that has been developed in order to make our model computationally tractable we show that in our model inquirers are indeed sometimes better off from an epistemic perspective overestimating the reliability of their own inquiries. We also show, by contrast, that people are rarely better off overestimating the reliability of others. On the basis of these observations we formulate a novel hypothesis about the value of overconfidence.     

Event perception: a mind-brain perspective

People perceive and conceive of activity in terms of discrete events. Here the authors propose a theory according to which the perception of boundaries between events arises from ongoing perceptual processing and regulates attention and memory. Perceptual systems continuously make predictions about what will happen next. When transient errors in predictions arise, an event boundary is perceived. According to the theory, the perception of events depends on both sensory cues and knowledge structures that represent previously learned information about event parts and inferences about actors' goals and plans. Neurological and neurophysiological data suggest that representations of events may be implemented by structures in the lateral prefrontal cortex and that perceptual prediction error is calculated and evaluated by a processing pathway, including the anterior cingulate cortex and subcortical neuromodulatory systems.     

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.     

The perception of women's status in Israel as a social problem

This study examines the perception of the status of women in Israel as a social problem, its cognitive structure and its correlates. The 994 respondents included a sample of university students, nurses, and female army officers. In general, the results suggest that feminist issues are perceived as less severe than most other social problems and that men perceive feminist issues as significantly less severe than do women. Factor analyses indicate that men and women think about social problems differently and that women have a broader more integrated conception of sex inequality. Sex, religiosity, education, and occupational context were all found to be significant predictors of perceptions of women's issues as social problems.     

Exchanging social positions: Enhancing perspective taking within a cooperative problem solving task

When people occupy different social positions within a cooperative task they experience discrepant role and situation demands and thus have divergent perspectives. The reported research predicts that exchanging social positions within a cooperative task can overcome divergences of perspective. This prediction was tested in two experiments using the Communication Conflict Situation. The first experiment (n = 88) found that position exchange increased the ability of dyads to solve a communication conflict arising through discrepant perspectives. The second experiment (n = 120) found that the effect of position exchange exceeds that of purely cognitive perspective taking, thus suggesting that it cannot be reduced to a purely cognitive process. Exchanging social positions is a newly identified and powerful social mechanism through which perspective taking, within a cooperative task, can be enhanced.

The social reality of the imaginary audience: a grounded theory approach

Traditional approaches to understanding the imaginary audience are challenged in this study. Three hundred sixty-one British schoolchildren (aged 14 and 15 years) were asked to express their worries and concerns, using grounded theory methodology. Qualitative responses were collated and coded according to emerging categories, with "what other people think" identified as the central concern. In particular, the findings are used to critique Elkind's (1967) theory of adolescent egocentrism. Data presented in this study suggest that adolescents worry about what other people think because there are real personal and social consequences. Such concerns are seen as being based in social reality and are not imaginary as Elkind suggested. In conclusion, new methodologies which place young people at the center of the analysis are advocated.     

Rethinking communication apprehension: a Myers-Briggs perspective

This study is an examination of relationships between Myers-Briggs personality type preferences, based on Jungian theory, and communication apprehension. Results showed that participants who preferred introversion or sensing reported significantly higher levels of communication apprehension in general and across the group, dyadic, meeting, and public contexts than did participants who preferred extraversion or intuition. In addition, participants who preferred feeling reported higher levels of communication anxiety in the public context than those who preferred thinking. Findings support the assumption that communication apprehension is biologically based, suggest that the Myers-Briggs type preference framework offers an alternative way of understanding communication apprehension, and point out the need for new approaches to understanding the phenomenon of communication apprehension.     

Demystifying social cognition: a Hebbian perspective

For humans and monkeys, understanding the actions of others is central to survival. Here we review the physiological properties of three cortical areas involved in this capacity: the STS, PF and F5. Based on the anatomical connections of these areas, and the Hebbian learning rule, we propose a simple but powerful account of how the monkey brain can learn to understand the actions of others by associating them with self-produced actions, at the same time discriminating its own actions from those of others. As this system appears also to exist in man, this network model can provide a framework for understanding human social perception.     

Interpersonal feedback: a social relations perspective

The social relations model (SRM; Kenny, 1994) is a statistical model for studying interpersonal perception and behavior that can be meaningfully applied to the group therapy situation. It consists of four primary components that correspond to (a) the general emotional or attitudinal climate of the group, (b) the perspective of the perceiver providing the feedback, (c) the group's consensual view of the target who receives the feedback, and (d) the unique relationship between the perceiver and the target. Because of its rigor and specificity, the components of the SRM may serve as a heuristic for thinking about interpersonal feedback in group therapy. A case example is used to demonstrate how an SRM perspective could guide therapists' ways of conceptualizing feedback.     

Making the audience a key participant in the science communication process

The public communication of science and technology has become increasingly important over the last several decades. However, understanding the audience that receives this information remains the weak link in the science communication process. This essay provides a brief review of some of the issues involved, discusses results from an audience-based study, and suggests some strategies that both scientists and journalists can use to modify media coverage in ways that can help audiences better understand major public issues that involve science and technology.

Pigeon pattern perception: limits on perspective invariance

Two experiments are reported in which the response of pigeons to perspective transformations of a pattern target was measured. In the first experiment an alphabet letter was taken as the pattern target (the 'positive') and the response to its perspective transforms was compared to the response to nontarget letters ('negatives') over the course of discrimination training. In the second experiment irregular quadrilaterals were used as positives and the responses to slight perspective deformations of the prototypes were compared to the responses to random transformations of the same magnitude under steady-state conditions. The amount of differential responding depended on the type of transformation. There was no differential response to targets rotated in the picture plane or around the horizontal axis in either experiment. There was differential response to small reductions and enlargements of the target. There was also differential response to translated targets, and this was seen irrespective of the amount of displacement. Results from targets rotated around the vertical axis were erratic, some target-plus-angle combinations elicited differential responding, but most did not. The erratic responses are attributed to symmetries in pattern elements that were abstracted as critical features. Pigeons therefore exhibit no true rotation invariance, limited size invariance, and complete shift invariance. It is argued that size invariance, but not position invariance, may depend on prior exposure to the alternatives.     

Emotion perception from a componential perspective

The common conceptual understanding of emotion is that they are multi-componential, including subjective feelings, appraisals, psychophysiological activation, action tendencies, and motor expressions. Emotion perception, however, has traditionally been studied in terms of emotion labels, such as “happy”, which do not clearly indicate whether one, some, or all emotion components are perceived. We examine whether emotion percepts are multi-componential and extend previous research by using more ecologically valid, dynamic, and multimodal stimuli and an alternative response measure. The results demonstrate that observers can reliably infer multiple types of information (subjective feelings, appraisals, action tendencies, and social messages) from complex emotion expressions. Furthermore, this finding appears to be robust to changes in response items. The results are discussed in light of their implications for research on emotion perception.     

Forces affecting perception of product comments on social‐WOM: An interactive,relational communication perspective

An attempt is made to explore the predicting factors of the perception of product comments on word‐of‐mouth through social media (social‐WOM). The concept of the Social Information Processing theory is borrowed to develop a 4‐stage framework in which 4 determinants drive the 2 perceptions of sWOM product comments through 2 sequential intervening mediators. The field study is conducted in Taiwan. Survey data are collected from a sample of 408 participants. The findings show that, in a social media community, intimacy, dominance, and informality alleviate the perception of environmental uncertainty, which in turn stimulates the involvement of sWOM product comments; eventually, both the outcome variables of trustability and quality of these comments arise. Additionally, task orientation and intimacy and dominance are able to drive community members to perceive the 2 outcome perceptions through the direct pathway of involvement. Furthermore, environmental uncertainty is capable of straightforwardly evoking the quality of comments.     

Interpersonal perception in a social context

Interpersonal perception among well-acquainted individuals in a social context was studied. High acquaintance was expected to provide perceivers with a large sample of target behaviors across situations. In turn, memory for acquaintances should be organized by social group and personality characteristics, as predicted by the social context-personality index theory. Differentiation of the target's traits in memory should produce a target effect on perception that is stronger than the perceiver effect. Furthermore, evidence for accuracy, meta-accuracy, independence of self- and other-perception, and reciprocity of affect were anticipated. A social relations analysis of data from a multiple-interaction, reciprocal design was used to study these phenomena. At the individual level, analyses indicated that perceptions of targets were determined primarily by target characteristics and secondarily by perceiver construction of the judgment. Also, perceivers judged targets as targets judged themselves, and targets knew in general how perceivers viewed them. Self- and other-perceptions were largely independent. Surprisingly, we did not observe dyadic meta-accuracy.     

Effects of alcohol on person perception: a social cognitive neuroscience approach

The acute effects of alcohol on cognitive processing of expectancy violations were investigated using event-related brain potentials and a cued recall task to index attentional and working memory processes associated with inconsistency resolution. As predicted, expectancy-violating behaviors elicited larger late positive potentials (LPP) and were recalled better than expectancy-consistent behaviors. These effects were moderated by alcohol and the valence of initial expectancies. For placebo group participants, positive targets performing negative behaviors elicited the largest LPP responses and were recalled best. For those in the alcohol groups, negative targets behaving positively elicited the largest LPP and recall responses. These findings suggest that alcohol does not globally impair working memory processes in person perception but instead changes the nature of valenced information processing. Findings are discussed in the context of alcohol's effects on working memory processes, reward sensitivity, and the prefrontal cortical structures thought to mediate them.
