Different action patterns for cooperative and competitive behaviour

The aim of the present study is to elucidate the influence of context on the kinematics of the reach-to-grasp movement. In particular, we consider two basic modes of social cognition, namely cooperation and competition. In two experiments kinematics of the very same action - reaching-to-grasp a wooden block - were analyzed in two different contexts provided by a cooperative task and competitive task. For the 'cooperation' tasks two participants were required to reach and grasp their respective objects and to cooperate to join the two objects in specific configurations in the middle of the working surface. For the 'competition' tasks, the two participants had to compete to place their own object first in the middle of the working surface. Results revealed specific kinematic patterns for cooperation and competition which were distinct from similar actions performed by each participant in isolation. Further, during the cooperation tasks, a high level of correlation between key kinematical parameters of the two participants was found. In accordance with evidence from neuroimaging, developmental and social psychology our results suggest the existence of motor patterns which reflect the intention to act in a social context.     

Consistency-based compliance across cultures

A field study investigated cross-cultural differences in choice-congruent behavior and its impact on compliance. U.S. and Asian participants received a request to complete an online survey and a month later they were approached with a larger, related request. Compliance with the initial request had a stronger impact on subsequent compliance among the U.S. participants than among the Asian participants. Despite their lower rate of compliance with the initial request, the U.S. participants who chose to comply were more likely than their Asian counterparts to agree to the subsequent request. Further analyses revealed that this effect was driven by differences in the individualistic/collectivistic orientation of the participants from the two cultures. Within both cultures, the more individualistic participants showed stronger consistency with their earlier compliance than the more collectivistically oriented participants.     

Victim’s innocence, social categorization, and the threat to the belief in a just world

This research studies people’s reactions to the suffering of victims, examining the hypothesis of the belief in a just world (BJW) (Lerner, 1980) according to which the awareness of innocent victims threatens people’s BJW, and extending the scope of BJW theory to intergroup contexts. An implicit measure of the threat to the BJW (Hafer, 2000a) is used in this research. After participants viewed a videotaped film containing the victimization story they performed an emotional modified Stroop task. Study 1 examined the threat to the BJW as function of the innocence of the victim at an interpersonal level of analysis. Results show that only the innocent victim threatens the observer’s BJW. Study 2 examined the threat to the BJW as function of the victim’s group and of the victim’s innocence. Results show that an ingroup victim threatens the participant’s BJW more than a victim belonging to an outgroup.     

The development of expert face processing: are infants sensitive to normal differences in second-order relational information?

Sensitivity to second-order relational information (i.e., spatial relations among features such as the distance between eyes) is a vital part of achieving expertise with face processing. Prior research is unclear on whether infants are sensitive to second-order differences seen in typical human populations. In the current experiments, we examined whether infants are sensitive to changes in the space between the eyes and between the nose and the mouth that are within the normal range of variability in Caucasian female faces. In Experiment 1, 7-month-olds detected these changes in second-order relational information. Experiment 2 extended this finding to 5-month-olds and also found that infants detect second-order relations in upright faces but not in inverted faces, thereby exhibiting an inversion effect that has been considered to be a hallmark of second-order relational processing during adulthood. These results suggest that infants as young as 5 months are sensitive to second-order relational changes that are within the normal range of human variability. They also indicate that at least rudimentary aspects of face processing expertise are available early in life.     

Status generalization in context: The moderating role of groups

Status generalization has been described as a process directly linking social status at the societal level to influence in interpersonal interactions, providing one mechanism through which status inequalities in society are maintained. It is argued in this paper that groups can moderate status generalization when a status characteristic is non-prototypical of the group. Two experiments are reported that measured the relative influence of an older and younger target within different group contexts: an undergraduate student group and a broader university group. In both experiments, the older target was more influential than the younger target in the context of the university group, but the younger target was more influential in the context of the undergraduate student group. Findings are discussed in relation to status generalization and referent informational influence as separate influence processes.     

Completed vs. interrupted priming: Reduced accessibility from post-fulfillment inhibition

We conceptualized an interrupted priming task as a state of an unfulfilled goal and a completed priming task as a post-fulfillment state. The accessibility of a primed construct was measured with both lexical decision and impression formation procedures. Lexical decisions showed enhanced accessibility of prime-related constructs after interrupted priming and reduced accessibility of the prime-related construct after completed priming. Replicating previous findings [Martin, L. L. (1986). Set/reset: Use and disuse of concepts in impression formation. Journal of Personality and Social Psychology, 51, 493-504], an ambiguous target was assimilated to the primed construct after interrupted priming, and was contrasted away from the primed construct after completed priming. Together, these results suggest that task fulfillment instigates inhibition of accessible constructs, in addition to (or instead of) a process of suppressing accessible constructs upon encountering a new target. These findings demonstrate how motivation can affect accessibility through inhibition as well as through suppression.     

A grotesque and dark beauty: How moral identity and mechanisms of moral disengagement influence cognitive and emotional reactions to war

Two studies examine the extent to which moral identity and moral disengagement jointly drive reactions to war. Study 1 finds support for a hypothesized positive relationship between moral disengagement and the perceived morality of a highly punitive response to the perpetuators of the September 11th attacks. It also finds that this effect was eliminated for participants who place high self-importance on their moral identities. Study 2 finds that moral disengagement effectively reduced the extent to which participants experienced negative emotions in reaction to abuses of Iraqi detainees by American soldiers; however, the effectiveness of moral disengagement was negated when participants’ moral identities were primed.     

Multiple Cues in Social Perception: The Time Course of Processing Race and Facial Expression

The purpose of the present study was to examine the time course of race and expression processing to determine how these cues influence early perceptual as well as explicit categorization judgments. Despite their importance in social perception, little research has examined how social category information and emotional expression are processed over time. Moreover, although models of face processing suggest that the two cues should be processed independently, this has rarely been directly examined. Event-related brain potentials were recorded as participants made race and emotion categorization judgments of Black and White men posing either happy, angry, or neutral expressions. Our findings support that processing of race and emotion cues occur independently and in parallel, relatively early in processing.     

The role of egocentrism and focalism in the emotion intensity bias

People sometimes judge their emotions, preferences, and attitudes to be more intense than those of other people. Two experiments tested whether this emotion intensity bias in direct comparisons results from two non-motivated cognitive processes—egocentrism and focalism. In Study 1, the intensity bias was found even when comparing a friend’s preferences to peers. In Study 2, attention given to own versus other’s preferences, and the referent of the comparison (self or others) were manipulated. Results indicated that attention to others reduced the bias, presumably by reducing egocentrism. Consistent with focalism, the bias also emerged when a friend was the target of comparison, and the bias was eliminated when the self was the referent rather than the target of comparison. In the discussion, we evaluate these accounts in light of some alternative explanations for the intensity bias.     

The role of social norm clarity in the influenced expression of prejudice over time

Social influence has been shown to be a powerful, but underexamined, tool in altering prejudice-related attitudes. Most notably, hearing one person condemn or condone discrimination can influence another person to do the same (Blanchard, Crandall, Brigham, & Vaughn, 1994). The current study assesses a potential underlying mechanism that may determine the extent to which participants are socially influenced to alter their prejudice-related beliefs: the clarity of the social norm regarding the expression of prejudice. In addition, the study assesses longer-term effects of social influence (see Stangor, Sechrist, & Jost, 2001). Results from 270 participants revealed that the extent of social influence was predicted by the clarity of the social norm for displaying prejudice and that participants were influenced both immediately and one month later by others’ opinions. We discuss the theoretical implications of the finding that one person can produce lasting change in another person’s prejudice-related belief system.
