Sex differences in the association of math achievement with visual-spatial and verbal working memory: Does the type of math test matter?

Previous research on sex differences in mathematical achievement shows mixed findings, which have been argued to depend on types of math tests used and the type of solution strategies (i.e., verbal versus visual-spatial) these tests evoke. The current study evaluated sex differences in (a) performance (development) on two types of math tests in primary schools and (b) the predictive value of verbal and visual-spatial working memory on math achievement. Children (N = 3175) from grades 2 through five participated. Visual-spatial and verbal working memory were assessed using online computerized tasks. Math performance was assessed five times during two school years using a speeded arithmetic test (math fluency) and a word problem test (math problem solving). Results from Multilevel Multigroup Latent Growth Modeling, showed that sex differences in level and growth of math performance were mixed and very small. Sex differences in the predictive value of verbal and visual-spatial working memory for math performance suggested that boys seemed to rely more on verbal strategies than girls. Explanations focus on cognitive and emotional factors and how these may interact to possibly amplify sex differences as children grow older.     

Predicting the Early Developmental Course of Symptoms of Attention Deficit Hyperactivity Disorder

Data from the National Institute of Child Health and Human Development Study of Early Child Care were examined to test whether: attention deficit/hyperactivity disorder (ADHD) symptoms remain stable from 54 months through early elementary school; behavioral inhibition and attention deficits assessed at 54 months predict ADHD symptoms in elementary school, even after controlling for their temporal stability; and early behavioral inhibition and attention deficits moderate the longitudinal stability in ADHD symptoms. Data were examined using continuous and categorical measures of symptoms. Modest stability in ADHD symptoms from 54 months to third grade was found. Measures of inhibition and inattention predicted later teacher ratings uniquely, but no evidence was found for moderation. Measures of preschool behavioral inhibition also predicted “persistently at risk status” defined by elevated teacher ratings over time. Results are discussed in terms of executive and motivational facets of inhibition that may be related to early signs of ADHD.     

Sex Differences in Perception: Exploring the Integration of Sensory Information with Respect to Vision and Proprioception

Inter- and intra-modal matching by right hand preferred Norwegian adults were tested using a matching task. The task required them to locate target pins visually, proprioceptively or in combination, while matching was always carried out without vision. When combined scores for both hands were analysed, the females showed superior performance in the intra-modal matching condition. For both groups, when the scores for the two hands were treated separately, superior performance was obtained in using the right hand to match under the visual condition. The only significant sex difference relative to hand preference was that the females matched the target more accurately with the right hand in the intra-modal matching condition. These findings are discussed relative to inter-hemispheric processing     

Forming and reacting to overall fairness: A cross-cultural comparison

This study compared the cross-cultural formation and reactions toward overall fairness perception of employees from the US, China, Korea, and Japan. Distributive justice was related to overall fairness less strongly for Americans and Japanese than for Chinese and Koreans. In contrast, interactional justice was related to overall fairness more strongly for Americans and Japanese than for Chinese and Koreans. As expected, materialism seems to provide a coherent account of these cultural differences. In addition, overall fairness showed a stronger effect on turnover intention for Americans than for Chinese and Koreans. For job satisfaction, the effect of overall fairness was stronger for Americans than for Chinese, Koreans, and Japanese. Power distance seems to provide an adequate account of these cultural differences.     

Family Therapy, You Make Me Feel Like Dancing

In this article we use our experience with ballroom dancing to revisit three central systemic/relational ideas—summativity, pragmatics/aesthetics, and communication—in order to reaffirm our theoretical grounding in family therapy and to connect that grounding to community-mindedness in therapy. Community-mindedness consists of deliberate attention to the socially constructed grand narratives that dominate clients and therapists in the process of therapy. A detailed example is provided.

Is Personality Related to Assessment Center Performance? That Depends on How Old You Are

Despite compelling arguments that performance in the assessment center (AC) should be related to personality, past research has failed to demonstrate a consistent link between personality and AC performance. This study investigated whether managerial candidates’ age could be moderating, and thus obscuring, specific personality–AC performance relations. A large sample of managers (N = 371) participated in an AC and also completed the leadership relevant personality scales of achievement, dominance, and exhibition from the Personality Research Form-E (PRF-E; Jackson, D. N. (1984). Manual for the personality research form. Port Huron, MI: Research Psychologists Press). Consistent with hypotheses, age moderated the relations of dominance and exhibition with AC performance (p < .05), such that dominance and exhibition were more strongly related to AC performance for older as opposed to younger managers. Results were discussed in terms of their implications for the criterion-related and construct validity of ACs.

Contrast and Rater-Perspective Effects on Judgments of Sexual Harassment Severity: What He Thinks She Thinks,and Vice Versa

We looked at whether ratings biases can influence judgments people make about sexually harassing behaviors. Online participants (N = 176) read and rated the severity of complaint scenarios describing different incidents of alleged harassment. We manipulated: (1) contrast effects, by having people judge other, independent scenarios before judging a target scenario, and (2) rater-perspective effects, by having people judge from both a self- and then an opposite-gender perspective. For the former, we hypothesized that if judgments about harassment are qualitatively similar to judgments made in other areas (e.g., performance appraisal), they too should show contrast effects. For the latter, we hypothesized people would use stereotypes about the other gender, thereby overestimating the true (i.e., self-perspective driven) gender difference. Results supported both hypotheses, suggesting that decision makers should be aware of the possible influence of biases when judging whether behaviors constitute harassment.
