Gender differences in adult word learning

In prior work, women were found to outperform men on short-term verbal memory tasks. The goal of the present work was to examine whether gender differences on short-term memory tasks are tied to the involvement of long-term memory in the learning process. In Experiment 1, men and women were compared on their ability to remember phonologically-familiar novel words and phonologically-unfamiliar novel words. Learning of phonologically-familiar novel words (but not of phonologically-unfamiliar novel words) can be supported by long-term phonological knowledge. Results revealed that women outperformed men on phonologically-familiar novel words, but not on phonologically-unfamiliar novel words. In Experiment 2, we replicated Experiment 1 using a within-subjects design, and confirmed gender differences on phonologically-familiar, but not on phonologically-unfamiliar stimuli. These findings are interpreted to suggest that women are more likely than men to recruit native-language phonological knowledge during novel word-learning.     

Drive and Direction: Empathy with Intended Targets Moderates the Proactive Personality–Job Performance Relationship via Work Engagement

Proactive employees are self-starting and driven. Thus, they typically exhibit high levels of work engagement. While work engagement reflects the degree to which employees are attentive and absorbed when performing their work tasks, it does not guarantee effective job performance unless their actions are strategic. We draw on Grant and Ashford’s (2008) proactivity framework to develop a drive and direction contingency model that expands our understanding of how and when proactive personality predicts job performance via work engagement. We argue that employee’s drive (represented by the positive relation of proactive personality with work engagement) predicts job performance only when the employee also has high (vs. low) empathy with their intended targets, such as customers. Empathy with intended targets allows employees to understand and feel their targets’ concerns and feelings, thus providing a direction that guides their work engagement to address their targets’ interests and predict job performance. Results from a multiple-source (employees, supervisors, and organizational records) lagged (T1–T2) field study and a lab experiment support our model. We discuss the implications, limitations, and future directions of our findings.     

The ripple effect of personality on social structure: self-monitoring origins of network brokerage

Despite growing interest in social network brokerage, its psychological antecedents have been neglected. One possibility is that brokerage relates to self-monitoring personality orientation. High self-monitors, relative to low self-monitors, in adapting their self-presentations to the demands of different groups, may occupy positions as brokers between disconnected social worlds. For 162 Korean expatriate entrepreneurs in a Canadian urban area, the results showed that those high in self-monitoring tended to occupy direct brokerage roles within the Korean community--in terms of their direct acquaintances being unconnected with each other. Those high in self-monitoring also tended to occupy indirect brokerage roles--in terms of the acquaintances of their acquaintances being unconnected with each other. Finally, for recent arrivals, those high in self-monitoring tended to establish ties to a wider range of important non-Korean position holders outside the community. These results (which controlled for strongly significant effects of network size on individuals' brokerage within the community) suggest a ripple effect of self-monitoring on social structure and contribute to a clearer understanding of how personality relates to brokerage at different levels.     

Noninvasive Brain Stimulation over the M1 Enhances Bimanual Force Control Ability: A Randomized Double-Blind Sham-Controlled Study

Well-coordinated bimanual force control is common in daily life. We investigated the effects of anodal transcranial direct current stimulation (tDCS) over the primary motor cortex on bimanual force control. Under a cross-over study, young adults (n = 19; female = 6, male = 13) completed three bimanual force control tasks at 5%, 25%, and 50% of bimanual maximum voluntary force (BMVF) before and after real or sham tDCS. Real tDCS enhanced accuracy at all BMVF, reduced variability at 5% BMVF, and increased coordination at 5% BMVF. Real tDCS improved force control at 5% and 25% BMVF, and especially increased bimanual coordination at 5% BMVF. These findings might have implications for establishing interventions for patients with hand force control deficits.     

Substance use and delinquency among adolescents with childhood ADHD: The protective role of parenting

Several domains of parenting have been identified as important for adolescent well-being. Whether these same domains are equally beneficial for adolescents with ADHD histories remains an empirical and clinically important question. This study examined whether parental knowledge of their teen's activities and whereabouts, consistency, support, and parent-adolescent conflict are associated with substance use and delinquency similarly for adolescents with and without a diagnosis of ADHD in childhood. A sample of 242 adolescents, 142 diagnosed with ADHD in childhood and prospectively followed into adolescence, and 100 without ADHD in childhood, were the focus of study. The relations between adolescent-reported outcomes (i.e., substance use and delinquency) and parenting behaviors were tested using latent variable modeling to determine both the effects of general (common) and specific (unique) parenting behaviors for participants with and without a history of ADHD. Adolescents' report of parental knowledge was a significant correlate of delinquency and substance use above and beyond other parenting variables and the variance in common across the parenting variables. More knowledge was associated with less delinquency and substance use for all participants, but parental knowledge was more strongly associated with alcohol use for adolescents with versus without childhood ADHD. These correlational findings suggest that, despite the increased difficulty of parenting youths with ADHD histories, actions taken by parents and youth to increase parental awareness may provide some protection against behavioral transgressions known to be elevated in this population.

General And Culturally Specific Factors Influencing Black And White Rape Survivors' Self-Esteem

Grounded in a culturally inclusive ecological model of sexual assault recovery framework, the influence of personal (e.g., prior victimization), rape context (e.g., degree of injury during last assault), and postrape response factors (e.g., general and cultural attributions, rape related coping) on self-esteem of Black and White college women, who were survivors of attempted and completed rape, were examined. As predicted, Black and White women identified similar general variables (e.g., general attributions) as important in the recovery process. Black women, however, identified a cultural factor (i.e., cultural attributions) as more important in influencing their reactions to the last rape compared to their White counterparts. Using path analysis, findings from this cross-sectional study indicated that severity of the last assault and prior victimization were related to lower self-esteem indirectly through avoidance coping strategies, and victim blame attributions for the latter. Results also suggested that the link between cultural attributions and self-esteem was explained through victim blame attributions, primarily for Black participants. The model accounted for 26% of variance in self-esteem.
