Ethnic identity, self-esteem, and ethnocentrism: a study of social identity versus multicultural theory of development

Social identity theory (SIT) proposes that the more strongly individuals identify with their group, the less favorable attitudes they hold toward dissimilar groups. In contrast, multicultural theory proposes that affirmation toward one's group--particularly with respect to ethnicity--should correspond with higher levels of acceptance toward dissimilar groups. These competing theories were examined with 486 non-Hispanic White, African American, and Hispanic/Latino university students to determine if support would be found for either theory. Consistent with SIT, levels of ethnic identity correlated significantly with levels of ethnocentrism for Whites and Hispanics but not for African Americans. African Americans obtained significantly higher ethnic identity and self-esteem scores than the other 2 groups. Implications of the findings are discussed.     

How conscious experience and working memory interact

Active components of classical working memory are conscious, but traditional theory does not account for this fact. Global Workspace theory suggests that consciousness is needed to recruit unconscious specialized networks that carry out detailed working memory functions. The IDA model provides a fine-grained analysis of this process, specifically of two classical working-memory tasks, verbal rehearsal and the utilization of a visual image. In the process, new light is shed on the interactions between conscious and unconscious aspects of working memory.     

Keeping Up with the Cloneses -- Issues in Human Cloning

The advent of cloning animals has created a maelstrom of social concern about the ethical issues associated with the possibility of cloning humans. When the ethical concerns are clearly examined, however, many of them turn out to be less matters of rational ethics than knee-jerk emotion, religious bias, or fear of that which is not understood. Three categories of real and spurious ethical concerns are presented and discussed: 1) that cloning is intrinsically wrong, 2) that cloning must lead to bad consequences, and 3) that cloning harms the organism generated. The need for a rational ethical framework for discussing biotechnological advances is presented and defended.     

College Students’ Perceptions of Peers Who Cheat1

Two studies investigated the efficacy of 3 theoretical models in explaining college students judgments of peers who cheat and of accomplices who assist cheaters. The value pluralism model predicted that accomplices who acted for money would be judged more harshly than those who acted from friendship; the attributional model predicted that cheaters whose actions were caused by internal controllable factors would be judged more harshly than those who actions were caused by external uncontrollable factors, and the relative preference model predicted that students who saw themselves as more likely to act as the cheater and accomplice did would make less harsh judgments. Overall, the results provided the best support for the relative preference model.
