Coordinated action relies on shared representations between interaction partners: people co-represent actions of others in order to respond appropriately. However, little is known about the social factors that influence shared representations. We investigated whether actions performed by in-group and out-group members are represented differently, and if so,(More)
Since the early twentieth century, psychologists have known that there is consensus in attributing social and personality characteristics from facial appearance. Recent studies have shown that surprisingly little time and effort are needed to arrive at this consensus. Here we review recent research on social attributions from faces. Section I outlines(More)
The amygdala is thought to perform a number of social functions, and has received much attention for its role in processing social properties of faces. In particular, it has been shown to respond more to facial expressions than to neutral faces, and more to positively valenced and negatively valenced faces than faces in the middle of the continuum. However,(More)
People rapidly form impressions from facial appearance, and these impressions affect social decisions. We argue that data-driven, computational models are the best available tools for identifying the source of such impressions. Here we validate seven computational models of social judgments of faces: attractiveness, competence, dominance, extroversion,(More)
OBJECTIVE The implementation of intensive insulin therapy in the intensive care unit is accompanied by an increase in hypoglycemia. We studied the relation between hypoglycemia on intensive care unit mortality, because the evidence on this subject is conflicting. DESIGN Retrospective database cohort study. SETTING An 18-bed medical/surgical intensive(More)
People make rapid and consequential social judgments from minimal (non-emotional) facial cues. There has been rapid progress in identifying the perceptual basis of these judgments using data-driven, computational models. In contrast, our understanding of the neural underpinnings of these judgments is rather limited. Meta-analyses of neuroimaging studies(More)
How do we model the complexity of social perception? A major methodological problem is that the space of possible variables driving social perceptions is infinitely large, thus posing an insur-mountable hurdle for conventional approaches. Here, we describe a set of data-driven methods whose objective is to identify quantitative relationships between(More)
More than 40 years of research have shown that people favor members of their ingroup in their impressions, attitudes, and behaviors. Here, we propose that people also form different mental images of minimal ingroup and outgroup members, and we test the hypothesis that differences in these mental images contribute to the well-established biases that arise(More)
Individuals perceive their own group to be more typical of a shared superordinate identity than other groups are. This in-group projection process has been demonstrated with both self-report and indirect measures. The two studies reported here extend this research to the visual level, specifically, within the domain of faces. Using an innovative(More)
