Trusting outgroup, but not ingroup members, requires control: neural and behavioral evidence.
Trust and cooperation often break down across group boundaries, contributing to pernicious consequences, from polarized political structures to intractable conflict. As such, addressing such conflicts require first understanding why trust is reduced in intergroup settings. Here, we clarify the structure of intergroup trust using neuroscientific and behavioral methods. We found that trusting ingroup members produced activity in brain areas associated with reward, whereas trusting outgroup members produced activity in areas associated with top-down control. Behaviorally, time pressure-which reduces people's ability to exert control-reduced individuals' trust in outgroup, but not ingroup members. These data suggest that the exertion of control can help recover trust in intergroup settings, offering potential avenues for reducing intergroup failures in trust and the consequences of these failures
Investigating the Early Stages of Person Perception: The Asymmetry of Social Categorization by Sex vs. Age
The wealth of information provided by facial cues presents challenges to our understanding of these early stages of person perception. The current study aimed to uncover the dynamics of processing multiply categorizable faces, notably as a function of their gender and age. Using a modified four-choice version of a mouse-tracking paradigm (which assesses the relative dominance of two categorical dimensions), the relative influence that sex and age have on each other during categorization of infant, younger adult, and older adult faces was investigated. Results of these experiments demonstrate that when sex and age dimensions are simultaneously categorized, only for infant faces does age influence sex categorization. In contrast, the sex of both young and older adults was shown to influence age categorization. The functional implications of these findings are discussed in light of previous person perception research
Democrats and Republicans Can Be Differentiated from Their Faces
Background: Individuals ’ faces communicate a great deal of information about them. Although some of this information tends to be perceptually obvious (such as race and sex), much of it is perceptually ambiguous, without clear or obvious visual cues. Methodology/Principal Findings: Here we found that individuals ’ political affiliations could be accurately discerned from their faces. In Study 1, perceivers were able to accurately distinguish whether U.S. Senate candidates were either Democrats or Republicans based on photos of their faces. Study 2 showed that these effects extended to Democrat and Republican college students, based on their senior yearbook photos. Study 3 then showed that these judgments were related to differences in perceived traits among the Democrat and Republican faces. Republicans were perceived as more powerful than Democrats. Moreover, as individual targets were perceived to be more powerful, they were more likely to be perceived as Republicans by others. Similarly, as individual targets were perceived to be warmer, they were more likely to be perceived as Democrats. Conclusions/Significance: These data suggest that perceivers ’ beliefs about who is a Democrat and Republican may be based on perceptions of traits stereotypically associated with the two political parties and that, indeed, the guidance of these stereotypes may lead to categorizations of others ’ political affiliations at rates significantly more accurate than chanc

Physical Therapists’ Nonverbal Communication Predicts Geriatric Patients’ Health Outcomes
Two studies explored the link between health care providers' patterns of nonverbal communication and therapeutic efficacy. In Study 1, physical therapists were videotaped during a session with a client. Brief samples of therapists' nonverbal behavior were rated by naive judges. Judges' ratings were then correlated with clients' physical, cognitive, and psychological functioning at admission, at discharge, and at 3 months following discharge. Therapists' distancing behavior was strongly correlated with short- and long-term decreases in their clients' physical and cognitive functioning. Distancing was expressed through a pattern of not smiling and looking away from the client. In contrast, facial expressiveness, as revealed through smiling, nodding, and frowning, was associated with short- and long-term improvements in functioning. In Study 2, elderly subjects perceived distancing behaviors of therapists more negatively than positive behaviors.Psycholog
