Differential susceptibility to discipline: the moderating effect of child temperament on the association between maternal discipline and early childhood externalizing problems.

This study investigated the interaction of child temperament and maternal discipline in the prediction of externalizing problems in early childhood. Interaction effects were evaluated in a sample of 227 one- to three-year-old children with relatively high externalizing problems scores on the Child Behavior Checklist/1 1/2-5. Child temperament was reported by the mothers, maternal discipline was observed in a laboratory session, and child outcome measures included both mother-reported externalizing problems and observed physical aggression. Results indicate that children with difficult temperaments are more susceptible to negative discipline (i.e., they showed more externalizing problems) as well as more susceptible to positive discipline (i.e., they showed fewer externalizing problems and less physical aggression), as compared with children with relatively easy temperaments. These findings provide empirical evidence for the differential susceptibility hypothesis and suggest directions for enhancing the effectiveness of interventions aimed at reducing early childhood externalizing problems.     

Some surprising findings on the involvement of the parietal lobe in human memory

The posterior parietal lobe is known to play some role in a far-flung list of mental processes: linking vision to action (saccadic eye movements, reaching, grasping), attending to visual space, numerical calculation, and mental rotation. Here, we review findings from humans and monkeys that illuminate an untraditional function of this region: memory. Our review draws on neuroimaging findings that have repeatedly identified parietal lobe activations associated with short-term or working memory and episodic memory. We also discuss recent neuropsychological findings showing that individuals with parietal lobe damage exhibit both working memory and long-term memory deficits. These deficits are not ubiquitous; they are only evident under certain retrieval demands. Our review elaborates on these findings and evaluates various theories about the mechanistic role of the posterior parietal lobe in memory. The available data point towards the conclusion that the posterior parietal lobe plays an important role in memory retrieval irrespective of elapsed time. However, the available data do not support simple dichotomies such as recall versus recognition, working versus long-term memory. We conclude by formalizing several open questions that are intended to encourage future research in this rapidly developing area of memory research.     

Explanations of success and derailment in upper-level management positions

Using an inventory based on findings from several qualitative studies, this investigation developed eight dimensions distinguishing successful senior managers from those who had derailed. Results showed that bosses' ratings of 86 successful senior managers on the eight dimensions were significantly higher than those of 83 who had derailed, providing empirical support for many of the earlier qualitative findings. Comparing the successful managers to the derailed suggests dimensions otherwise overlooked which are important to consider when assessing managerial talent.     

Resolutions of control episodes between well and affectively ill mothers and their young children

Control interactions between 87 well and affectively ill mothers and their 15- to 51-month-old children were studied. Spontaneously occurring control interventions (conceptualized as episodes of interaction between mother and child) were coded from 90 minutes of videotaped interactions in a naturalistic laboratory apartment setting. The results suggest developmental changes in mother-child interaction in the 2nd to 4th years of life: the increase of the rate of immediate maternal success (p less than .05) and compromise (p less than .05), on the decrease in maternal use of power (ultimate success by enforcement, p less than .01). Well mothers achieved compromise with their children, particularly daughters, more often than did affectively ill mothers (p less than .05). Affectively ill mothers more often than well mothers avoided confrontation with their children (p less than .05). The impairments in control interventions of affectively ill mothers were exacerbated by the severity of the disorder.
