An invariant dimensional liability model of gender differences in mental disorder prevalence: evidence from a national sample

Epidemiological studies of categorical mental disorders consistently report that gender differences exist in many disorder prevalence rates and that disorders are often comorbid. Can a dimensional multivariate liability model be developed to clarify how gender impacts diverse, comorbid mental disorders? We pursued this possibility in the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC; N = 43,093). Gender differences in prevalence were systematic such that women showed higher rates of mood and anxiety disorders, and men showed higher rates of antisocial personality and substance use disorders. We next investigated patterns of disorder comorbidity and found that a dimensional internalizing-externalizing liability model fit the data well, where internalizing is characterized by mood and anxiety disorders, and externalizing is characterized by antisocial personality and substance use disorders. This model was gender invariant, indicating that observed gender differences in prevalence rates originate from women and men's different average standings on latent internalizing and externalizing liability dimensions. As hypothesized, women showed a higher mean level of internalizing, while men showed a higher mean level of externalizing. We discuss implications of these findings for understanding gender differences in psychopathology and for classification and intervention.     

The independent effects of skin tone and facial features on Whites' affective reactions to Blacks

Research on skin tone and Afrocentric features provides evidence that people use phenotypes (visible physical characteristics) to make inferences about the degree to which stereotypes about the racial group apply to the individual (i.e., to make impressions of others). However, skin tone and Afrocentric features have been confounded in prior research on this topic. The present study examines whether facial features (lip thickness, nose width) have effects on Whites' affective reactions to Black targets, above and beyond the well-documented skin tone effect by experimentally crossing variation in facial features and skin tone. The results showed that both skin tone and facial features independently affected how negatively, as opposed to positively, Whites felt toward Blacks using both implicit and explicit measures. The findings that Whites reacted more negatively toward Blacks with darker skin tone and more prototypical facial features than toward Blacks with lighter skin tone and less prototypical facial features on the explicit measure may indicate that Whites are unaware of the negative effects that Blacks' phenotypes can have on their racial attitudes. The present study demonstrated that subtle facial features, in addition to salient skin tone, also play an important role when predicting Whites' feelings about Blacks. One implication is that it is important to raise people's awareness about the effects that Blacks' phenotypes can have on their attitudes.     

Subliminal priming and effects of hand dominance

In the masked priming paradigm, motor responses to targets are influenced by previously presented subliminal primes, and are guided by facilitatory and inhibitory mechanisms that depend on prime-target compatibility/duration. In this study, we evaluate subliminal-driven priming in right- and left-handers during unimanual as well as bimanual tasks. The data from the unimanual tasks confirmed that prime-target compatibility affects performance as a function of prime-target duration. In a bimanual setting, the preferred hand benefitted from facilitation in both handedness groups whereas the non-preferred hand showed a positive priming effect only in left-handers. This denotes that left-handers are more susceptible to response activation of either hand. In addition, inhibitory priming had a stronger effect on the non-preferred than preferred hand, independent of handedness group. Overall, the findings suggest that subliminal-driven mechanisms that assist adaptive motor behavior are sensitive not only to extrinsic (task-related) factors such as prime-target compatibility but also to intrinsic (performer-related) factors such as hand dominance. The data further provide support for handedness-specific effects in motor functions and underline a significant role of hand dominance in the control of bimanual actions.     

The perceptual span during foveally-demanding visual target localization

Foveally-induced processing load deteriorates target localization performance in vision-guided tasks. Here, participants searched for a target embedded among coded distractors. High processing load was effected by instructing some participants to use the coded distractors to guide their search for the target. Other participants (in the low processing load condition) were not apprised of the code. The experiment examined whether increased processing load alters the span of effective processing (i.e. perceptual span) by (a) reducing its size, (b) altering its shape, or (c) reducing its size and altering its shape. The results demonstrated a reduction in the size of the perceptual span, with no significant change to its shape. It is argued that when distractors are processed beyond simply rejecting them as non targets, the perceptual span shrinks with increasing processing load. The findings are discussed in contrast to a general interference theory that predicts a change in vision-guided performance without a shrinking of the perceptual span.     

The Impact of Neighborhood Factors on the Well-Being of Survivors of Intimate Partner Violence Over Time

Intimate partner violence (IPV) is a pervasive social problem impacting the psychological well-being of millions of US women annually. The extant literature draws our attention to the devastating mental health effects of IPV, but largely overlooks how ecological factors may further explain survivors' well-being. This study examined how neighborhood disadvantage may contribute to survivors' compromised well-being, in addition to the abuse women experienced. Neighborhood disorder and fear of victimization significantly impacted survivors' well-being, over and above abuse. Although between-women effects of neighborhood disorder and fear were unrelated to change in women's depression or quality of life (QOL), significant within-woman effects were detected. Change in neighborhood disorder was negatively associated with change in QOL, and this relationship was fully mediated by fear. While no direct relationship between change in neighborhood disorder and depression was detected, an indirect effect through survivors' fear was revealed. Implications for future research and practice are discussed.     

What's mom got to do with it? Contributions of maternal executive function and caregiving to the development of executive function across early childhood

Executive functions (EFs; e.g. working memory, inhibitory control) are mediated by the prefrontal cortex and associated with optimal cognitive and socio‐emotional development. This study provides the first concurrent analysis of the relative contributions of maternal EF and caregiving to child EF. A group of children and their mothers (n = 62) completed age‐appropriate interaction (10, 24, 36 months) and EF tasks (child: 24, 36, and 48 months). Regression analyses revealed that by 36 months of age, maternal EF and negative caregiving behaviors accounted for unique variance in child EF, above and beyond maternal education and child verbal ability. These findings were confirmed when using an early child EF composite‐our most reliable measure of EF – and a similar pattern was found when controlling for stability in child EF. Furthermore, there was evidence that maternal EF had significant indirect effects on changes in child EF through maternal caregiving. At 24 months, EF was associated with maternal EF, but not negative caregiving behaviors. Taken together, these findings suggest that links between negative caregiving and child EF are increasingly manifested during early childhood. Although maternal EF and negative caregiving are related, they provide unique information about the development of child EF.

The eternal yearning

Parker Palmer defines spirituality as ‘the eternal yearning to be connected with something larger than our own egos’ (2003, 121). This yearning is an innate human need that transcends age, culture, ethnicity and belief. Despite deficit assumptions about young people, they are drawn to this need to surmount the ego and contribute to something larger than their own wants and needs. Two counter stories of young people involved in social activism outline how this is achieved. These are stories of contribution, compassion, empathy and understanding. Implications for schools are outlined including the range of learning that social activism inspires.     

What are you dieting for? The role of lay theories in dieters' goal setting

Through a qualitative study of a sample of Weight Watchers dieters, this research provides insight about the relationship between goal setting and lay theories—people's basic assumptions about the malleability of their personal attributes. We find that dieters set very different types of superordinate and subordinate goals depending on the lay theory (entity vs. incremental) they hold. Dieters who hold entity theory, which underscores immutability of abilities, set superordinate goals focused on avoiding negative social evaluations. These dieters also seem to set subordinate goals that minimize effort in diet, physical activity, and the use of group meetings necessary for weight loss. Among dieters holding incremental theory, which emphasizes malleability of abilities through learning, weight loss is guided by superordinate goals that promote change in the self. Incremental‐theory dieters also set subordinate goals that encourage rather than limit revamping lifestyle. These findings offer contributions to lay theories and goal setting in consumer research as well as implications for developing more successful weight‐loss practices.

Purity matters more than harm in moral judgments of suicide: Response to Gray (2014)

Many people judge suicide to be immoral. We have found evidence that these moral judgments are primarily predicted by people’s belief that suicide taints the soul and by independent concerns about purity. This finding is inconsistent with accounts that define morality as fundamentally based upon harm considerations. In this commentary, we respond to a critique of our finding, and we provide further support for our original conclusions. Even when applying new exclusion criteria to our data, an examination of effect sizes demonstrates that concerns about purity robustly and meaningfully explain variance in moral judgments of suicide. While harm concerns sometimes predict moral judgments of suicide alongside purity concerns, they reliably explain a much smaller proportion of the variance than do purity concerns. Therefore, data from six studies continue to suggest that the relevance of harm concerns for moral judgments of suicide is substantially overshadowed by the contribution of purity concerns.
