Psychosocial costs of racism to Whites: Understanding patterns among university students

This investigation adds to the growing body of scholarship on the psychosocial costs of racism to Whites (PCRW), which refer to consequences of being in the dominant position in an unjust, hierarchical system of societal racism. Extending research that identified 5 distinct constellations of costs of racism (L. B. Spanierman, V. P. Poteat, A. M. Beer, & P. I. Armstrong, 2006), the authors used multinomial logistic regression in the current study to examine what factors related to membership in 1 of the 5 PCRW types during the course of an academic year. Among a sample of White university freshmen (n = 287), the authors found that (a) diversity attitudes (i.e., universal diverse orientation and unawareness of privilege) explained PCRW type at entrance, (b) PCRW type at entrance explained participation in interracial friendships at the end of the year, (c) 45% of participants changed PCRW type during the course of the year, and (d) among those who changed type, particular PCRW types at entrance resulted in greater likelihood of membership in particular PCRW types at the end of the year.

Continuity and change in social and physical aggression from middle childhood through early adolescence

For a sample followed from age 9–13 (N=281), this investigation examined developmental trajectories for social and physical aggression as measured by teacher ratings. Trajectories for both forms of aggression were estimated first separately, then jointly. Mean levels of both social and physical aggression decreased over time for the overall sample, but with high variability of individual trajectories. Subgroups followed high trajectories for both social and physical aggression. Joint estimation yielded six trajectories: low stable, low increasers, medium increasers, medium desisters, high desisters, and high increasers. Membership in the high increaser group was predicted by male gender, unmarried parents, African American ethnicity, and maternal authoritarian and permissive parenting. Permissive parenting also predicted membership in the medium increaser group. This is one of the first studies to examine social aggression longitudinally across this developmental period. Though the results challenge the claim that social aggression is at its peak in early adolescence, the findings emphasize the importance of considering different developmental trajectories in trying to understand origins and outcomes of aggression.

Extraversion predicts individual differences in women’s face preferences

Extraversion is positively associated with various indices of women’s mate quality (e.g., facial symmetry and attractiveness). Since such indices are thought to predict variation in women’s preferences for masculine men, we investigated the relationships between each of the ‘Big 5’ personality factors and women’s preferences for facial masculinity. Extraversion, but not the other four personality factors, was positively correlated with women’s preferences for masculinity in men’s, but not women’s, faces. Additionally, extraversion mediated the positive relationship between women’s self-rated attractiveness and their preferences for masculinity in men’s faces, suggesting that extraversion may play a role in condition-dependent mate preferences. Unexpectedly, openness to experience was associated with women’s preferences for femininity in faces of both sexes and this association was independent of that between extraversion and women’s preferences for masculine men. This is the first study that we know of to implicate personality traits in individual differences in women’s preferences for masculine men.     

Developmental shifts in fMRI activations during visuospatial relational reasoning

To investigate maturational plasticity of fluid cognition systems, functional brain imaging was undertaken in healthy 8-19 year old participants while completing visuospatial relational reasoning problems similar to Raven's matrices and current elementary grade math textbooks. Analyses revealed that visuospatial relational reasoning across this developmental age range recruited activations in the superior parietal cortices most prominently, the dorsolateral prefrontal, occipital-temporal, and premotor/supplementary cortices, the basal ganglia, and insula. There were comparable activity volumes in left and right hemispheres for nearly all of these regions. Regression analyses indicated increasing activity predominantly in the superior parietal lobes with developmental age. In contrast, multiple anterior neural systems showed significantly less activity with age, including dorsolateral and ventrolateral prefrontal, paracentral, and insula cortices bilaterally, basal ganglia, and particularly large clusters in the midline anterior cingulate/medial frontal cortex, left middle cingulate/supplementary motor cortex, left insula-putamen, and left caudate. Findings suggest that neuromaturational changes associated with visuospatial relational reasoning shift from a more widespread fronto-cingulate-striatal pattern in childhood to predominant parieto-frontal activation pattern in late adolescence.     

Conceptualization and measurement of temporal focus: The subjective experience of the past,present, and future

Temporal focus is the attention individuals devote to thinking about the past, present, and future, and the concept is important because it affects how people incorporate perceptions about past experiences, current situations, and future expectations into their attitudes, cognitions, and behavior. However, temporal focus has not been clearly defined nor situated in a nomological network of constructs. In addition, existing measures of temporal focus suffer from various shortcomings. In this paper, we advance the concept of temporal focus by critically examining its conceptualization, developing a new measure of temporal focus (Temporal Focus Scale; TFS), and evaluating the validity (i.e., construct, convergent, discriminant, nomological, and predictive validity) of the TFS across four studies. We conclude that understanding how individuals focus their attention toward the past, present, and future clarifies their responses to explicit and implicit temporal information, which suggests that a variety of research streams would benefit from incorporating the concept of temporal focus.     

Maternal control style and the mastery motivation of one-year-olds

Forty-one mothers and their 12-month-old infants participated in a study of the effects of maternal control style on infant mastery motivation. Three scales were designed to assess maternal control style during a mother-infant play session. Mastery motivation was assessed in an experimenter-administered structured toy play procedure. Three components, persistence, competence, and affect, comprised the measure of mastery motivation. Mothers also completed questionnaires on child-rearing attitudes, infant temperament, and control style. Results showed that maternal attitudes and behavior were correlated with infant mastery motivation. More specifically: autonomy-oriented control behavior, sensitive care and knowledge of child-rearing were positively related to infant mastery motivation. The results provide converging evidence regarding the multiple aspects of maternal behavior which affect infant motivation.
