Predicting conjunction typicalities by component typicalities

In two studies, we investigated to what extent typicalities in conjunctive concepts phrased as relative clauses—such aspets that are also birds—can be predicted from simple functions of constituent typicalities and from extensions of such functions. In a first study, analyses of a large aggregated data set, based on seven different experiments, showed that a calibrated minimum rule model and some extensions of this model accounted for a very large part of the variance in the conjunction typicalities. The same models can also account for the so-called guppy effect. A psychological explanation is presented, which states that typicalities in contrast categories, likepets that are not birds andbirds that are not pets, further improve the prediction of conjunction typicalities. This hypothesis is tested in a second study.     

Ethical issues in genetics

The first section of the Notes on Moral Theology reviews ethical issues in genetics through the lenses of privacy-confidentiality; risk-benefit analysis in relation to prenatal diagnosis and gene therapy; and freedom-determinism/human dignity in the context of cloning. The author provides an overview of developments in genetics and highlights thematic issues common to these developments.     

Preschool Children's Emotional Expressions with Peers: The Roles of Gender and Emotion Socialization

This study examined whether mothers and fathers reported using different emotion socialization strategies and whether these differences were related to preschoolers' gender and emotional expressiveness during peer play. Ninety percent of the children were Caucasian, 6% were Asian-American, and 4% were Mexican-American. The positive expressive behavior of 82 preschoolers participating in two conflict eliciting situations with two same gender peers were coded. The scores for the two sessions were averaged. All of the mothers and 63 of the fathers were administered three emotion socialization questionnaires. Results revealed that girls expressed more positive emotion than boys. In addition, mothers and fathers also reported using different emotion socialization practices and, in some cases, this was dependent upon their child's gender. The findings also showed that mothers' and fathers' reports of emotion socialization practices were differentially related to children's emotionally expressive behavior during peer play. In addition, fathers' emotion socialization practices accounted for unique variance in children's emotionally expressive behavior over and above that explained by the maternal emotion socialization variables. These findings highlight the importance of mothers' and fathers' emotion socialization practices for preschoolers' emotional competence in emotionally challenging situations with peers.     

How attributional ambiguity shapes physiological and emotional responses to social rejection and acceptance

The authors examined White and Black participants' emotional, physiological, and behavioral responses to same-race or different-race evaluators, following rejecting social feedback or accepting social feedback. As expected, in ingroup interactions, the authors observed deleterious responses to social rejection and benign responses to social acceptance. Deleterious responses included cardiovascular (CV) reactivity consistent with threat states and poorer performance, whereas benign responses included CV reactivity consistent with challenge states and better performance. In intergroup interactions, however, a more complex pattern of responses emerged. Social rejection from different-race evaluators engendered more anger and activational responses, regardless of participants' race. In contrast, social acceptance produced an asymmetrical race pattern--White participants responded more positively than did Black participants. The latter appeared vigilant and exhibited threat responses. Discussion centers on implications for attributional ambiguity theory and potential pathways from discrimination to health outcomes.     

Eavesdropping on social life: The accuracy of stranger ratings of daily behavior from thin slices of natural conversations

In two studies the authors examined the accuracy of stranger ratings of daily behavior based on thin slices of natural conversations. Methodologically, the studies extend past research by using a behavioral accuracy criterion, benchmarking zero-acquaintance accuracy against target and informant accuracy, and employing a representative design that sampled contexts from targets’ daily situations. Theoretically, the studies investigate how stereotypes influence the accuracy of first impressions depending on their sample-based validity. Across both studies, after listening to five conversational snippets (2.5 min total), the ratings of strangers were as accurate as the targets’ and informants’ ratings. Further, ratings for gender-stereotypic behaviors with a kernel of truth resulted in greater initial accuracy than ratings for gender-stereotypic behaviors with no kernel of truth.     

Predictors of Protest Among Anti‐Globalization Demonstrators1

Anti‐globalization protest is analyzed as a function of ideological opposition to social hierarchy and identification with the social movement. Demonstrators (N = 145) at the Summit of the Americas in Québec City in April 2001 completed measures of social dominance orientation (SDO), social identification with the anti‐globalization movement, and the likelihood of engaging in various protest behaviors. Results supported the hypothesis that social identification mediates the link between SDO and inclinations toward 2 forms of collective action (anti‐globalization protest and indirect protest), whereas non‐normative protest tended to be endorsed most strongly by male demonstrators. These relationships inform theoretical perspectives on politicized collective identity and the social psychology of social movement participation.
