The Social Nature of Perception and Action

ABSTRACT— Humans engage in a wide range of social activities. Previous research has focused on the role of higher cognitive functions, such as mentalizing (the ability to infer others' mental states) and language processing, in social exchange. This article reviews recent studies on action perception and joint action suggesting that basic perception–action links are crucial for many social interactions. Mapping perceived actions to one's own action repertoire enables direct understanding of others' actions and supports action identification. Joint action relies on shared action representations and involves modeling of others' performance in relation to one's own. Taking the social nature of perception and action seriously not only contributes to the understanding of dedicated social processes but has the potential to create a new perspective on the individual mind and brain.     

Neurobehavioral sequelae of child sexual abuse.

This study examined intellectual and memory functioning in a sample of sexually abused children compared to demographically and age-matched controls. The severity of abuse and other pertinent factors were also examined in relation to cognitive performance. Elevated levels of psychopathology were present in the abused children, as well as diminished performance on tasks influenced by attention/concentration. However, after controlling for differences in IQ and socioeconomic status (SES), significant differences in memory function were not found. Results are discussed in the context of stress effects on cognition and the potential resiliency of cognitive function in children undergoing treatment for sexual abuse.     

CORRELATES OF RELATIONSHIP SATISFACTION IN LESBIAN COUPLES

This study broadens the construct of intimate relationships to include the experience of lesbian couples. Various psychological variables were assessed in both partners of 275 lesbian couples who considered themselves to be dual career. Because of the paucity of information on lesbian relationships in the literature, considerable attention is first given to describing this sizable sample. Individual and couple scores on each variable were correlated with relationship satisfaction scores. Among individuals, role conflict and personal autonomy were found to correlate negatively with relationship satisfaction, whereas dyadic attachment, power, intimacy, self-esteem, and life satisfaction were all positively correlated with relationship Satisfaction. Although career commitment was not correlated with relationship satisfaction among individuals, differences between partners'levels of career commitment correlated negatively with each partner's relationship satisfaction. The findings counter extant stereotypes regarding lesbian relationships and provide a more accurate basis for developing an heuristic model of intimate relationships among women.     

Developmental changes in personal goal orientation from young to late adulthood: from striving for gains to maintenance and prevention of losses

Using a multimethod approach, the authors conducted 4 studies to test life span hypotheses about goal orientations across adulthood. Confirming expectations, in Studies 1 and 2 younger adults reported a primary growth orientation in their goals, whereas older adults reported a stronger orientation toward maintenance and loss prevention. Orientation toward prevention of loss correlated negatively with well-being in younger adults. In older adults, orientation toward maintenance was positively associated with well-being. Studies 3 and 4 extend findings of a self-reported shift in goal orientation to the level of behavioral choice involving cognitive and physical fitness goals. Studies 3 and 4 also examine the role of expected resource demands. The shift in goal orientation is discussed as an adaptive mechanism to manage changing opportunities and constraints across adulthood.     

Effects of antisocial personality, cocaine and opioid dependence, and gender on eye movement control

Substance-dependent patients have been reported to exhibit abnormal smooth pursuit and saccadic eye movements. However, contrasts of the effects of different substances and the effects of comorbid psychiatric symptoms such as antisocial personality have rarely been performed. Separate analyses examined the effects of cocaine dependence, opioid dependence, or antisocial personality disorder. In each analysis, sex was included as an additional grouping factor. The dependent measures were the gain of smooth pursuit eye movement and the delay and accuracy of saccadic eye movement. Analyses of covariance indicated that both cocaine dependence and antisocial personality, but not opiate dependence, were associated with a significant reduction in gain of smooth pursuit eye movement. Cocaine dependence and antisocial personality also slowed the onset of saccadic eye movements, but only in men. No group differences were found in the accuracy of saccadic eye movements. The results suggest that the neurophysiological effects of cocaine dependence and antisocial personality overshadow the effects of heroin. The significance of these findings for visual attention and reading skill has yet to be assessed.     

Breaking the waves: age differences in electrical brain activity when reading text with distractors

The authors tested whether older adults have greater difficulty than younger adults in ignoring task-irrelevant information during reading as a result of age-related decline in inhibitory processes. Participants were shown target sentences containing distractor words. They were instructed to read aloud each sentence and ignore distractors. The N400 event-related potential (ERP) was used to measure the extent of semantic processing of target and distracting information. It showed that younger adults semantically processed both target and distracting material, whereas online processing of target sentences in older adults was disrupted by the distractors. In older adults, memory for target information related to their susceptibility to distraction and inhibition efficiency. Implications for age-differences in inhibitory control, working memory, and resource capacity are discussed.     

The interaction of personality and job scope in predicting turnover

The interaction of employee personality characteristics and job scope in the prediction of turnover was studied. One hundred and nine individuals employed as machine operators (low-scope job) and scientific and technical personnel (high-scope job) within a large manufacturing organization were the sample. No direct relationships were found between personality characteristics and turnover for the combined sample of employees on high- and low-scope jobs. When correlational analyses were carried out within job scope samples it was evident that personality and job scope interacted in predicting turnover. For employees on high-scope jobs, turnover was negatively related to the need for achievement and positively related to the need for affiliation. Turnover was negatively related to the need for affiliation among employees on low-scope jobs. The implications of these findings for future research on turnover were discussed.
