Does social exclusion motivate interpersonal reconnection? Resolving the "porcupine problem".

Evidence from 6 experiments supports the social reconnection hypothesis, which posits that the experience of social exclusion increases the motivation to forge social bonds with new sources of potential affiliation. Threat of social exclusion led participants to express greater interest in making new friends, to increase their desire to work with others, to form more positive impressions of novel social targets, and to assign greater rewards to new interaction partners. Findings also suggest potential boundary conditions to the social reconnection hypothesis. Excluded individuals did not seem to seek reconnection with the specific perpetrators of exclusion or with novel partners with whom no face-to-face interaction was anticipated. Furthermore, fear of negative evaluation moderated responses to exclusion such that participants low in fear of negative evaluation responded to new interaction partners in an affiliative fashion, whereas participants high in fear of negative evaluation did not.

They all look the same to me (unless they're angry): from out-group homogeneity to out-group heterogeneity.

People often find it more difficult to distinguish ethnic out-group members compared with ethnic in-group members. A functional approach to social cognition suggests that this bias may be eliminated when out-group members display threatening facial expressions. In the present study, 192 White participants viewed Black and White faces displaying either neutral or angry expressions and later attempted to identify previously seen faces. Recognition accuracy for neutral faces showed the out-group homogeneity bias, but this bias was entirely eliminated for angry Black faces. Indeed, when participants' cognitive processing capacity was constrained, recognition accuracy was greater for angry Black faces than for angry White faces, demonstrating an out-group heterogeneity bias.

Functional projection: how fundamental social motives can bias interpersonal perception.

Results from 2 experimental studies suggest that self-protection and mate-search goals lead to the perception of functionally relevant emotional expressions in goal-relevant social targets. Activating a self-protection goal led participants to perceive greater anger in Black male faces (Study 1) and Arab faces (Study 2), both out-groups heuristically associated with physical threat. In Study 2, participants' level of implicit Arab-threat associations moderated this bias. Activating a mate-search goal led male, but not female, participants to perceive more sexual arousal in attractive opposite-sex targets (Study 1). Activating these goals did not influence perceptions of goal-irrelevant targets. Additionally, participants with chronic self-protective and mate-search goals exhibited similar biases. Findings are consistent with a functionalist, motivation-based account of interpersonal perception.

When authorities' commands backfire: attributions about consensus and effects on deviant decision making.

The perception of consensus typically produces conformity, but specific attributional circumstances may produce deviance instead. Ironically, the command of an authority figure may create one such circumstance. Participants were presented with scenarios in which they had to make a choice between 2 options. Prior to their decision, they observed others all making a single choice. In some conditions, this consensus occurred following an authority's explicit command to make that choice. Results revealed the hypothesized effect--the authority's command led participants to make deviant decisions-and revealed that this effect was moderated by the authority's continued presence, expertise, the target(s) of the command, and the ability of perceivers to use their cognitive resources.

Psychology and culture.

Psychological processes influence culture. Culture influences psychological processes. Individual thoughts and actions influence cultural norms and practices as they evolve over time, and these cultural norms and practices influence the thoughts and actions of individuals. Large bodies of literature support these conclusions within the context of research on evolutionary processes, epistemic needs, interpersonal communication, attention, perception, attributional thinking, self-regulation, human agency, self-worth, and contextual activation of cultural paradigms. Cross-cultural research has greatly enriched psychology, and key issues for continued growth and maturation of the field of cultural psychology are articulated.

Fear of the dark: interactive effects of beliefs about danger and ambient darkness on ethnic stereotypes.

Two studies examined effects of ambient darkness and chronic beliefs about danger on activation of stereotypes about Blacks. Chronic beliefs were measured by a Belief in a Dangerous World (BDW) questionnaire. In Study, 1, participants in either a dimly lit or dark room saw photos of Black men and rated the extent to which specific traits described the cultural stereotype of Blacks. In Study 2, participants in either a well-lit or dark room completed reaction-time tasks assessing implicit associations between Blacks and evaluative attributes. Separate measures assessed stereotypes connoting danger versus those that are merely derogatory. Results revealed BDW x Darkness interactions on activation of danger-relevant stereotypes: BDW positively predicted activation in dark but not in light conditions. It appears that chronic beliefs about danger can facilitate activation of functionally relevant stereotypes, but this effect occurs primarily under circumstances (such as darkness) that heuristically suggest vulnerability to harm. Conceptual implications are discussed.

Selective pressures on the once and future contents of ethnic stereotypes: effects of the communicability of traits.

It is hypothesized that traits that are most likely to be the subject of social discourse (i.e., most communicable) are most likely to persist in ethnic stereotypes over time and that this effect is moderated by the extent to which an ethnic group is the subject of social discourse. Study 1 yielded communicability ratings of 76 traits. Study 2 tested the relation between a trait's communicability and its presence in stereotypes of 4 Canadian ethnic groups. Study 3 tested the relation between a trait's communicability and its persistence over time in stereotypes of 8 American ethnic groups. Results supported the hypotheses. A communication-based analysis of stereotypes appears helpful in predicting persistence and change in the contents of stereotypes of real groups in the real world.
