Gender displays in portrait photographs

Following the research of Goffman (1976) and Henley (1977) on sex differences in nonverbal behavior, 1,296 portrait photographs from high school and university yearbooks and from the media files of a university were analyzed for sex differences. Females smiled with a significantly greater frequency and expansiveness than males and head canted significantly more than males. Results supporting the hypothesis that males would face the camera more directly than females failed to reach the acceptable significance level. The prediction that persons working in opposite-sex roles would deintensify their gender displays failed to gain support.The author expresses appreciation to Bill Drell and Andrea Wilson for their assistance in data collection.     

The generalization of deferred imitation in enculturated chimpanzees (Pan troglodytes)

Deferred imitation of object-related actions and generalization of imitation to similar but not identical tasks was assessed in three human-reared (enculturated) chimpanzees, ranging in age from 5 to 9 years. Each ape displayed high levels of deferred imitation and only slightly lower levels of generalization of imitation. The youngest two chimpanzees were more apt to generalize the model's actions when they had displayed portions of the target behaviors at baseline, consistent with the idea that learning is more likely to occur when working within the "zone of proximal development." We argue that generalization of imitation is the best evidence to date of imitative learning in chimpanzees. Electronic Publication     

Talking facilitates cognitive-emotional processes of adaptation to an acute stressor

The authors examined the influence of talking and the social context of talking on cognitive-emotional processes of adjustment to stressors. Two hundred fifty-six undergraduates viewed a stressful stimulus and were then assigned to a no-talk control condition or 1 of 3 talk conditions: talk alone, talk to a validating confederate, or talk to an invalidating confederate. Two days later, they were reexposed to the stressor. Compared with individuals in the no-talk condition, those in the talk alone and validate conditions had a lower level of intrusive thoughts in the 2-day interim, and they had lower perceived stress when reexposed to the stressor. The effects of talking and validation on perceived stress appeared to be mediated by lowered intrusions. The benefits of talking were diluted when disclosures were invalidated. These findings suggest that talking about acute stressors can facilitate adjustment to stressors through cognitive resolution.     

Motor performance under three levels of trait anxiety and stress

In general, the interactive effects of trait anxiety and stress on motor performance have been neglected in assessing the viability of the inverted-U hypothesis. The present investigation tested the inverted-U hypothesis using three levels of trait anxiety and psychological stress. Performance results produced an inverted-U curve for the three levels of stress, with subjects in the moderate-stress condition displaying the highest performance. In addition, a significant trait anxiety x stress interaction indicated that high trait-anxious subjects performed best in the low-stress condition, while low trait-anxious subjects performed best in the high-stressed condition. The discussion concerns theories attempting to explain the relationship between anxiety and motor performance.     

Examining changes in relationship adjustment and life satisfaction in marriage

The current study examined the association between relationship adjustment and life satisfaction before marriage to 6 years into marriage in a sample of 126 couples. Results showed that both premarital relationship adjustment and premarital life satisfaction uniquely predicted marital adjustment 6 years into marriage. Premarital life satisfaction, but not premarital relationship adjustment, predicted life satisfaction 6 years into marriage. While premarital relationship adjustment scores were not uniquely associated with future life satisfaction scores, changes in relationship adjustment were positively associated with future life satisfaction. These findings are supportive of the idea that helping people to improve their relationships may increase overall life satisfaction. The findings also suggest that, while an individual's base level of life satisfaction may set some parameters for the course of relationship adjustment, changes in life satisfaction over time impact marital adjustment. Starting marriage with higher life satisfaction may increase chances for a happier marriage. Overall, the findings suggest that life satisfaction plays a role in marital adjustment over time, and that it is important to consider life satisfaction as not only an outcome associated with relationship adjustment but also as a predictor of relationship adjustment.     

Boredom proneness in anger and aggression: effects of impulsiveness and sensation seeking

The present study was a replication and extension of Rupp and Vodanovich’s (1997) work on the role of boredom proneness in anger expression and aggression. In addition to replicating their primary analyses, impulsiveness and sensation seeking were included to determine the potential impact of these variables on the relationships between boredom proneness and anger and aggression. Two hundred and twenty-four college student volunteers completed measures of boredom proneness, impulsiveness, sensation seeking, anger expression, and aggression. Findings were consistent with Rupp and Vodanovich (1997) but demonstrated more pervasive effects of external boredom proneness on aggression. Hierarchical multiple regression analyses demonstrated that the relationships between external boredom proneness and trait anger, anger expression/control, and aggression persisted even after accounting for impulsiveness and sensation seeking. Boredom due to a lack of external stimulation predicted one’s propensity to experience anger, maladaptive anger expression, aggression, and deficits in anger control.     

It's not that bad: Social challenges to emotional disclosure enhance adjustment to stress

Studies conducted in the United States (n=115) and Spain (n=146) examined how talking about an acute stressor in different social contexts influences cognitive, emotional, and physiological adjustment. In both studies, female college students viewed a video dramatizing a real-life, gang rape scene on two separate days. After the first viewing, participants were randomly assigned to one of four social conditions: no talk, talk alone about their reactions, talk to a validating confederate about their reactions, or talk to a challenging confederate about their reactions. Participants in the challenge condition showed the greatest emotional, cognitive, and physiological benefits across cultures, whereas participants in the validate and talk conditions evidenced only modest benefits. These findings suggest that the social context of disclosure has a strong influence on adjustment processes and that providing an alternative and more sanguine perspective can help individuals recover from acute stressors.
