Social Dominance Orientation,Gender, and Increasing Educational Exposure1

Using a large panel sample of undergraduates, we measured the social dominance orientation (SDO) scores of men and women once a year across a 4½‐year period. Employing repeated‐measures ANOVAs, we found that, even after controlling for the character of students' academic majors (hierarchy enhancing or hierarchy attenuating), males showed significantly higher SDO scores than did females across the entire college career. The data are discussed in terms of the invariance hypothesis within social dominance theory.     

Prediction in infants and adults: A pupillometry study

Adults use both bottom‐up sensory inputs and top‐down signals to generate predictions about future sensory inputs. Infants have also been shown to make predictions with simple stimuli and recent work has suggested top‐down processing is available early in infancy. However, it is unknown whether this indicates that top‐down prediction is an ability that is continuous across the lifespan or whether an infant's ability to predict is different from an adult's, qualitatively or quantitatively. We employed pupillometry to provide a direct comparison of prediction abilities across these disparate age groups. Pupil dilation response (PDR) was measured in 6‐month olds and adults as they completed an identical implicit learning task designed to help learn associations between sounds and pictures. We found significantly larger PDR for visual omission trials (i.e. trials that violated participants’ predictions without the presentation of new stimuli to control for bottom‐up signals) compared to visual present trials (i.e. trials that confirmed participants’ predictions) in both age groups. Furthermore, a computational learning model that is closely linked to prediction error (Rescorla‐Wagner model) demonstrated similar learning trajectories suggesting a continuity of predictive capacity and learning across the two age groups.     

Intragroup dissonance: Responses to ingroup violation of personal values

The present research draws on cognitive dissonance theory [Festinger, L. (1957). A theory of cognitive dissonance. Stanford, CA: Stanford University Press] and social identity theory [Tajfel, H. (Ed.). (1978). Differentiation between social groups. London: Academic Press] to examine how group members respond to discrepancies between their personal values and the behavior of an ingroup. In two experiments we manipulated whether participants’ ingroup violated a personal value (providing basic healthcare in Experiment 1 and self-reliance in Experiment 2) and measured participants’ emotional responses and strategies for reducing discomfort. As expected, individuals experienced psychological discomfort (but not negative self-directed emotion), when an ingroup, but not when an outgroup, violated a personal value, and this discomfort mediated participants’ disidentification with their group (Experiment 1) and value-adherence activism (Experiment 2).     

Assimilation,multiculturalism, and colorblindness: Mediated and moderated relationships between social dominance orientation and prejudice

Using correlational and experimental data, we examined the degree to which personal and perceived normative support for the acculturation ideologies of assimilation, multiculturalism, and colorblindness mediated and moderated the relationship between social dominance orientation (SDO) and prejudice among 299 White students at three American colleges. Correlational results indicated that personal support for the acculturation ideologies mediated the SDO–prejudice relationship. Personal support for assimilation (a hierarchy-enhancing ideology) positively related to SDO; multiculturalism and colorblindness (hierarchy-attenuating ideologies) negatively related to SDO. An experimental manipulation varied whether assimilation, multiculturalism, or colorblindness was considered normative in the United States. In addition to a control, a fifth condition primed the Obama presidency. SDO related most strongly to prejudice toward American immigrants and ethnic minorities when assimilation norms and the Obama presidency were primed. Efforts to reduce the associations between SDO and prejudice are discussed in terms of highlighting hierarchy-attenuating national norms of multiculturalism and colorblindness.     

How does celebrity meaning transfer? Investigating the process of meaning transfer with celebrity affiliates and mature brands

The influence of celebrity spokespersons has largely been examined using source models from the communication literature that feature explicit persuasive messages. Alternatively, theorizing by McCracken (1989) offers a more comprehensive explanation based on meaning transfer. Our research elaborates McCracken's model by investigating a cognitive process underlying meaning transfer. Evaluative conditioning procedures are used as the tool to expose this process. To assess celebrity influence as it may operate in the marketplace, well-known brands and well-known celebrities are featured. The results support, at the individual level, McCracken's theoretical axiom concerning meaning transfer from celebrity affiliate to brand.     

Exploring the Intersecting Health Risks of Substance Abuse,Sexual Risk,and Violence for Female South African Teen Dropouts

The study sought to better understand the cultural contexts of the risks for adolescent females who have dropped out of school. Focus groups were conducted with 37 Black and Coloured females aged 13 to 17 in Cape Town, South Africa. Data were analysed using content analysis. Methamphetamine, cannabis, and alcohol were used by both, however, Black teens also used methaqualone and Coloured teens used heroin and ecstasy. Some teens traded sex for drugs and others did so at the request of their drug-addicted mothers. Teens revealed high rates of violence, including rape, and many myths and barriers about condom use, revealing risky sex behaviours. Conclusion—Cultural nuances between the two groups will help inform the adaptation of an HIV prevention intervention.     

The role of representational status and item complexity in parent–child conversations about pictures and objects

Mother–child conversations about pictures systematically differ from mother–child conversations about objects: Pictures are more likely than objects to elicit talk about kinds, whereas objects are more likely than pictures to elicit talk about individuals. The purpose of the current study is to examine whether this difference between pictures and objects is explained by differences in item complexity. Mothers and their 4-year-old children were randomly assigned to one of two conditions: simple or complex. In each condition, participants viewed 12 toy objects and 12 pictures, matched for content. The items were either highly detailed (complex condition) or very plain (simple condition). Replicating previous research, mothers and children provided relatively more focus on kinds when talking about pictures, and relatively more focus on individuals when talking about objects. The current results go further, however, to demonstrate that this effect is independent of the items’ complexity. We therefore propose that the picture–object difference is not due to low-level differences in amount of perceptual detail provided, but rather is due to the greater ease with which pictures serve as representations [DeLoache, J. S. (1991). Symbolic functioning in very young children: Understanding of pictures and models. Child Development, 62, 736–752]. These data indicate the ways in which a fundamental conceptual distinction between kinds and individuals arises in different linguistic expressions and in different contexts.     

Intergroup consensus/disagreement in support of group-based hierarchy: an examination of socio-structural and psycho-cultural factors

A meta-analysis examined the extent to which socio-structural and psycho-cultural characteristics of societies correspond with how much gender and ethnic/racial groups differ on their support of group-based hierarchy. Robustly, women opposed group-based hierarchy more than men did, and members of lower power ethnic/racial groups opposed group-based hierarchy more than members of higher power ethnic/racial groups did. As predicted by social dominance theory, gender differences were larger, more stable, and less variable from sample to sample than differences between ethnic/racial groups. Subordinate gender and ethnic/racial group members disagreed more with dominants in their views of group-based hierarchy in societies that can be considered more liberal and modern (e.g., emphasizing individualism and change from traditions), as well as in societies that enjoyed greater gender equality. The relations between gender and ethnic/racial groups are discussed, and implications are developed for social dominance theory, social role theory, biosocial theory, social identity theory, system justification theory, realistic group conflict theory, and relative deprivation theory.

Memory and brain volume in adults prenatally exposed to alcohol

The impact of prenatal alcohol exposure on memory and brain development was investigated in 92 African-American, young adults who were first identified in the prenatal period. Three groups (Control, n=26; Alcohol-related Neurodevelopmental Disorder, n=36; and Dysmorphic, n=30) were imaged using structural MRI with brain volume calculated for multiple regions of interest. Memory was measured using the Verbal Selective Reminding Memory Test and its nonverbal counterpart, the Nonverbal Selective Reminding Memory Test, which each yielding measures of learning and recall. For both Verbal and Nonverbal Recall and Slope, linear trends were observed demonstrating a spectrum of deficits associated with prenatal alcohol exposure. Dysmorphic individuals performed significantly poorer than unexposed controls on 5 of 6 memory outcomes. Alcohol-exposed individuals demonstrated significantly lower total brain volume than controls, as well as lower volume in a number of specific regions including hippocampus. Mediation analyses indicated that memory performance associated with effects of prenatal alcohol exposure was mediated from dysmorphic severity through hippocampal volume, particularly right hippocampus. These results indicate that the association between the physical effects of prenatal alcohol exposure and deficits in memory are mediated by volumetric reduction in specific brain regions.
