What matters most? The relative role of mentoring and career capital in career success

This study used a career capital framework to compare the relative role of mentoring and three other forms of career capital (human, agentic, and developmental network capital) in predicting career success. Using a three-wave longitudinal design we found that mentoring added value, above and beyond the other forms of career capital, in predicting promotions and advancement expectations. However, although mentoring mattered for career success, it represented just a part of a constellation of career resources that are embedded within individuals and their relationships. Implications for future research are discussed.     

Interpersonal trust and organizational citizenship behavior

This study investigates the relationship between certain individual level determinants of interpersonal trust and its impact on organizational citizenship behavior. The participants (N=303) were top, middle, and lower level executives from manufacturing and services sectors. The results indicate that interaction frequency, consistency, and competence are significant predictors of interpersonal trust. Interpersonal trust is positively associated with organizational citizenship behavior, and it also partially mediated the relationship between individual level factors and organizational citizenship behavior. The results imply that the development of trust at the interpersonal level may be used as a strategy to motivate the employees to engage in extra role behaviors to ensure improved individual and organizational performance.     

Reduced right hemisphere activation in severely abused violent offenders during a working memory task: An fMRI study

This study uses functional magnetic resonance imaging (fMRI) to address two important gaps in our knowledge of brain functioning and violence: (1) What are the brain correlates of adults in the community who have suffered severe physical abuse early in life and who go on to perpetrate serious violence in adulthood? (2) What characterizes those who experience severe physical abuse but who refrain from serious violence? Four groups of participants recruited from the community (controls, severe physical child abuse only, serious violence only, and severely abused, seriously violent offenders) underwent fMRI while performing a visual/verbal working memory task. Violent offenders who had suffered severe child abuse show reduced right hemisphere functioning, particularly in the right temporal cortex. Abused individuals who refrain from serious violence showed relatively lower left, but higher right, activation of the superior temporal gyrus. Abused individuals, irrespective of violence status, showed reduced cortical activation during the working memory task, especially in the left hemisphere. Brain deficits were independent of IQ, history of head injury, task performance, cognitive strategy, and mental activity during the control task. Findings constitute the first fMRI study of brain dysfunction in violent offenders, and indicate that initial right hemisphere dysfunction, when combined with the effects of severe early physical abuse, predisposes to serious violence but that relatively good right hemisphere functioning protects against violence in physically abused children.

Memory for information about sex differences

To test the selective recall hypothesis, male and female adolescents listened to a tape recording of 30 “findings” about sex differences. Fifteen of the findings were pro-female and 15 were anti-female. After being given free recall and then cued recall tests, the subjects completed the British version of the attitudes towards women scale. Multiple regression analysis supported the prediction that males, and those with more negative attitudes to wards women, recalled less pro- and more anti-female items, and vice versa. The importance of selective recall to studies of social cognition is discussed.     

Hand Preference in India

The degree of asymmetric handedness was measured by a 22-item hand preference questionnaire in a sample of 442 Indian subjects. Factor analysis of the data for right-handers yielded four item-clusters: Gross activities, skilled activities (general), skilled activities (specific), and activities subject to social pressure. Identical analysis for left-handers yielded three item-clusters: Activities that are executed with difficulty, with ease, and with greater frequency. The degree of asymmetric handedness in right-handers was positively (high) correlated with an index of social pressure against left-hand use, especially for the items, writing and eating. The correlation was negative (moderate) in left-handers, however, who had preferred the right hand for eating purposes.
