Group socialization and prejudice: the social transmission of intergroup attitudes and beliefs

In order to examine the social transmission of prejudice in the military, attitudes and beliefs of Francophone (minority) and Anglophone (majority) prospective military officers toward their own and other groups were assessed at the beginning and at the end of a four‐year officer‐training program. Consistent with social dominance theory and system justification theory, majority group members become significantly more negative toward outgroups (e.g. Francophones, civilians and immigrants) and more likely to internalize beliefs that legitimize the economic gap between Francophones and Anglophones in Canada. Moreover, as predicted on the basis of self‐categorization theory, the results show that identification with the category ‘Canadian Forces Officers’ assessed at the midpoint in the program, moderates the change in intergroup attitudes and beliefs. Finally, minority group members did not internalize negative stereotypes of their own group. These results provide important evidence for the role of group socialization in the explanation of intergroup attitudes and beliefs and suggest that social identification is a key factor in group socialization, consistent with self‐categorization theory.

Endogenous cortisol level interacts with noradrenergic activation in the human amygdala

Animal studies show that high cortisol levels exert their effect on stressful task performance via modulation of the amygdala. Availability of noradrenaline in this brain region appears to be a critical prerequisite for this effect. This relationship between noradrenaline and cortisol is explained by an animal model where the amygdala constitutes a crucial region for this interaction. In humans this model has not been extensively tested so far. In a previously reported study human subjects (aged 20.93+/-2.38) were scanned using fMRI when watching sets of emotional and neutral pictures after taking the beta-adrenergic antagonist propranolol or placebo. Stimulus sets consisted of 92 pictures, divided in four emotional categories that ranged from neutral scenes of domestic objects (CAT1) to extremely negative scenes of mutilation or accidents (CAT4). Confrontation with arousing emotional pictures, accompanied by increased noradrenaline levels, evoked increased amygdala activation under placebo but not under betablocker condition. This new and additional analysis of this data set was carried out to determine the effect of differential endogenous cortisol levels on amygdala activation. Cortisol levels during scanning were determined using salivary samples and subjects were post hoc divided in a High (n=14) and Low cortisol group (n=14). When subjects were watching emotional stimuli, presumably associated with enhanced noradrenaline (NA) levels, amygdala activation was contrasted between the two cortisol groups. We hypothesized that emotional stimuli would elicit more amygdala activation in the High than in the Low cortisol group. Here we demonstrate indeed a significant interaction effect of the endogenous cortisol level with increasing activation in the amygdala under placebo but not under betablocker condition, thereby extending the rodent based model of a synergistic effect of the two stress hormones to the human.

Recalling semantic information about personally known faces and voices

Previous research that investigated whether biographical information about familiar people is harder to retrieve from voices than from faces produced contrasting results. However, studies that used a strict control of the content of spoken extracts reported that semantic information about familiar people is easier to retrieve when recognising a face than when recognising a voice. In all previous studies faces and voices of famous people were used as stimuli. In the present study, personally familiar people's voices and faces (standard faces and blurred faces) were used. Presenting such people (i.e., participants’ teachers) allowed controlling still more strictly the content of the spoken extracts since it was possible to ask all the target persons to speak the same words. In addition, it was previously stressed that we encounter famous people's faces in the media more frequently than we hear their voice. This methodological difficulty was presumably reduced when teachers’ faces were presented. Present results showed a significant decrease in retrieval of biographical information from familiar voices relative to blurred faces even though the level of overall recognition was similar for blurred faces and voices. The role of the relative distinctiveness of voices and faces is discussed and further investigation is proposed.     

The Balance-Scale Dilemma: Either the Subject or the Experimenter Muddles Through

We examined two critiques of rule-assessment methodology: (a) the method does not take into consideration other rules that subjects use to solve problems, and (b) its multiple-choice format misrepresents subjects' cognitive level. In Study 1, high school students completed a paper-and-pencil, multiple-choice balance scale questionnaire. Their performance was assessed with Siegler's original rules and a revised set of rules that included an addition and a qualitative proportionality rule. Results showed that Siegler's Rule 3 was not homogeneous and that distinguishing specific patterns of answers among Rule 3 subjects increased the diagnostic value of the rule-assessment methodology. In Study 2, we compared rule-assessment methodology to the Piagetian clinical model. High school students solved balance-scale problems within each method. Results indicated an overall match between Piagetian levels and Siegler's rules, with the exception of Rule 3, suggesting again the pertinence of specifying alternative rules.     

Gender and Compensation: Understanding the Impact of Gender and Gender Stereotypes in Children’s Rewards

Children’s understanding of rewards for task completion was examined in the context of gender, and gender-based stereotypes. Eighty-eight children (43 girls, M_overall?=?58.39 months) completed a measure assessing gender-based occupational stereotypes. This measure, along with gender, was used to predict children’s self-reward for undergoing the testing, as well as their reward for a fictional other child having undergone the same procedure. The methodology provided a novel approach for studying reward allocation in children, as it did not require children to divide resources between themselves and another child for completing the same task. An occupation-based stereotype measure was found to predict the self-reward, as well as the reward allocated to the other child. In addition, the participant’s gender predicted self-reward, and an interaction between participant gender and gender of the experimenter contributed to predicting the other child reward. Overall, these findings suggest that gender and gender-based stereotyping have an impact on reward allocation of young children. Implications of these results in the context of reward allocation research among children and adult populations are discussed.

Investigating Correlates of Self-Regulation in Early Childhood with a Representative Sample of English-Speaking American Families

Children who possess less self-regulatory skill are at a disadvantage when compared to children who demonstrate greater skill at regulating their emotions, cognitions and behavior. Children with these regulatory deficits have difficulty connecting with peers, generating relationships with teachers, negotiating their social world, and succeeding academically. By understanding the correlates of self-regulatory abilities, interventions can be developed to ensure that children at-risk for poor self-regulation receive the support necessary to enhance their regulatory skills. Using data from a nationally representative survey of English-speaking American parents with children between the ages of two and eight (n = 1,141), we evaluated a host of demographic and parenting variables to isolate the correlates of self-regulation. Older children were found to have fewer regulatory problems than younger children while children from low-income homes and male children were found to have greater problems with self-regulation. Minority status, household composition (single vs multi-parent), and parental education were not significant correlates of self-regulation. Findings also illustrate the powerful relationship between parenting style and self-regulation. Parents who rely on nurturing parenting practices that reinforce the child’s sense of autonomy while still maintaining a consistent parenting presence (i.e., authoritative parenting) have children who demonstrate stronger self-regulatory skills. Parents who exert an excess of parental control (i.e., authoritarian parents) have children with weaker self-regulatory skills. And lastly, parents who have notable absence of control (i.e., permissive parents) are more likely to have children with considerable regulatory deficits. Results offer implications for both practitioners and scholars.
