When personal identities confirm versus conflict with group identities: Evidence from an intergroup paradigm

Permissions were not obtained for sharing the full text of this article.This study provides an experimental investigation of the consequences of conflict between children's personal identities and experimentally manipulated group identities. Elementary-school-aged children (N = 82, ages 5-11) attending a summer school program rated their own academic and athletic abilities and were then randomly assigned to one of two novel groups. Children's views of the academic and athletic skills of the novel groups were assessed both before and after information about the groups' academic and athletic skills was manipulated via posters placed in their classrooms. Following the manipulation, children's self-views, ingroup identification, and intergroup attitudes were assessed. Results indicated that (a) in the absence of information about the novel groups, children projected their personal identities onto their ingroup identities, (b) children maintained their ingroup identities in the face of new information that should have altered their ingroup identities, and (c) more positive personal identities predicted ingroup bias, which in turn predicted happiness with one's ingroup membership. The latter finding suggests that a tendency for children to generalize from their idiosyncratic positive self-views, rather than an indiscriminate desire for self-enhancement or positivity, may be responsible for ingroup bias

Dispelling negative expectancies: The impact of interaction goals and target characteristics on the expectancy confirmation process

The present study examined the impact of the interaction goals of perceivers and the characteristics of targets of a negative expectancy on the expectancy confirmation process. Perceivers were led to expect that their future interaction partner might have difficulty performing well under pressure. Perceivers were also placed in an interaction setting that made one of two interaction goals relevant: whereas some were encouraged to consider the partner as a possible teammate for a cooperative game; others were encouraged to have a casual conversation. Orthogonal to the interaction manipulation, subjects interacted with a target whose expectancy-relevant characteristics, if discovered during the interaction, could either support or refute the expectancy. Results indicated that the interaction goals perceivers inferred from the interaction setting influenced the extent to which they probed for information relevant to their negative expectancies. Their search strategies influenced what they discovered about the target, and these strategy-dependent discoveries, in turn, shaped their final impressions of the target. From this we argue that both the interaction goals of the perceivers and the characteristics of the targets of a negative expectancy are critical determinants of the fate of negative expectancies.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/27441/1/0000481.pd

Explaining illness with evil: pathogen prevalence fosters moral vitalism

Pathogens represent a significant threat to human health leading to the emergence of strategies designed to help manage their negative impact. We examined how spiritual beliefs developed to explain and predict the devastating effects of pathogens and spread of infectious disease. Analysis of existing data in studies 1 and 2 suggests that moral vitalism (beliefs about spiritual forces of evil) is higher in geographical regions characterized by historical higher levels of pathogens. Furthermore, drawing on a sample of 3140 participants from 28 countries in study 3, we found that historical higher levels of pathogens were associated with stronger endorsement of moral vitalis- tic beliefs. Furthermore, endorsement of moral vitalistic beliefs statistically mediated the previously reported relationship between pathogen prevalence and conser- vative ideologies, suggesting these beliefs reinforce behavioural strategies which function to prevent infection. We conclude that moral vitalism may be adaptive: by emphasizing concerns over contagion, it provided an explanatory model that enabled human groups to reduce rates of contagious disease

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

Responses to Ingroup Moral Transgressions

When ingroup members behave immorally, when do other group members seize the moral high ground and denounce them? The current research probes the mechanisms that motivate such acts of moral courage.

Restoring Honor by Slapping or Disowning the Daughter

The psychological processes underlying honor violence against kin are poorly understood. We assumed that honor violence against daughters who violate a gendered norm is designed to uphold family honor and nurture positive links to the community. Four studies with Indian men supported this formulation. As expected, endorsement of honor violence (i.e., slapping or disowning the daughter) increased insofar as perceived community awareness of the violation increased. Moreover, endorsement of honor violence was especially common among those whose identities were closely aligned (“fused”) with their community. Finally, a desire to restore threatened family honor, rather than a motivation to prevent future dishonor, motivates honor violence against daughters; conversely, a desire to prevent future dishonor motivates constructive activities such as advising. Ironically, a benign, culturally universal desire to maintain positive ties to the community can encourage community members to endorse violence toward transgressive kin
