The widely used and cited Social Readjustment Rating Scale developed by Holmes and Rahe (1967) was comprehensively revised and updated. The new instrument, containing 51 major life events, was administered to a national sample of 5000. Respondents were asked to rate the stressfulness of each life event on a 1–100 scale. Completed surveys were returned by 3122 individuals (62.4%). Responses were analyzed using repeated measures MANOVA and profile analysis. Major results included: (a) statistically and practically significant differences in mean ratings for the 51 life events; (b) five overlapping themes in the top 20 rated life events—death and dying, healthcare, crime and the criminal justice system, financial/economic issues, and family-related issues; and (c) an amazing level of agreement concerning perceived life event stressfulness, regardless of gender, age, or income level.  相似文献

Both theory and empirical evidence suggest that adolescents engage in risk behaviour to gain mature status, thereby becoming popular among their peers. Using a cross-sectional design with 20 school classes from higher secondary schools in Austria and the Netherlands, associations between risk behaviour and social status in late adolescence were examined (N = 408, Mage = 16.95, SD = 0.81, 50% male). Popularity and likeability were assessed as distinct facets of social status in adolescence using peer nominations. Self-reported risk behaviour included alcohol, tobacco and marijuana use, as well as sexual intercourse. Using a latent variable approach, results showed that in accordance with our assumptions, risk behaviour was strongly associated with popularity, but not with likeability. This study shows that in Austria and the Netherlands, associations between risk behaviour and social status among peers are in line with findings from outside of Europe. Theoretical and practical implications of these results are discussed and proposals for future research are given.  相似文献

This study aimed to explore the peer group's role in childhood aggression. Participants (N = 356), aged 8.92 to 13.67 years (M = 11.22, SD = .96), were asked to pretend that they had been placed in a team and were then provided with information regarding their team's norms (aggression vs. helping) and their position within the team (prototypical vs. peripheral). Subsequently, participants were asked to rate the likelihood that they would directly or indirectly aggress towards another team. When compared to children in the helping norm condition, those in the aggression norm condition reported a significantly higher likelihood of engaging in direct and indirect aggression. For indirect aggression, prototypical members of aggressive groups also reported being more likely to engage in such behaviour than peripheral members of these groups did. Further, peripheral members of aggressive groups reported a greater likelihood of engaging in indirect aggression than either peripheral or prototypical members of helping groups. The contribution of these results to our understanding of the group mechanisms underlying childhood aggression is discussed.  相似文献

This study examined motivational effects of feedback on motor learning. Specifically, we investigated the influence of social-comparative feedback on the learning of a balance task (stabilometer). In addition to veridical feedback (error scores reflecting deviation from the target horizontal platform position) about their own performance after each trial, two groups received false normative information about the “average” score of others on that trial. Average performance scores indicated that the participant's performance was either above (better group) or below (worse group) the average, respectively. A control group received veridical feedback about trial performance without normative feedback. Learning as a function of social-comparative feedback was determined in a retention test without feedback, performed on a third day following two days of practice. Normative feedback affected the learning of the balance task: The better group demonstrated more effective balance performance than both the worse and control groups on the retention test. Furthermore, high-frequency/low-amplitude balance adjustments, indicative of more automatic control of movement, were greater in the better than in the worse group. The control group exhibited more limited learning and less automaticity than both the better and the worse groups. The findings indicate that positive normative feedback had a facilitatory effect on motor learning.  相似文献

Two experiments investigated the role that different face regions play in a variety of social judgements that are commonly made from facial appearance (sex, age, distinctiveness, attractiveness, approachability, trustworthiness, and intelligence). These judgements lie along a continuum from those with a clear physical basis and high consequent accuracy (sex, age) to judgements that can achieve a degree of consensus between observers despite having little known validity (intelligence, trustworthiness). Results from Experiment 1 indicated that the face's internal features (eyes, nose, and mouth) provide information that is more useful for social inferences than the external features (hair, face shape, ears, and chin), especially when judging traits such as approachability and trustworthiness. Experiment 2 investigated how judgement agreement was affected when the upper head, eye, nose, or mouth regions were presented in isolation or when these regions were obscured. A different pattern of results emerged for different characteristics, indicating that different types of facial information are used in the various judgements. Moreover, the informativeness of a particular region/feature depends on whether it is presented alone or in the context of the whole face. These findings provide evidence for the importance of holistic processing in making social attributions from facial appearance.  相似文献

Previous research has found age-related declines in social perception tasks as well as the ability to engage in joint attention and orienting covert attention (i.e., absence of eye movements) in response to an eye gaze cue. We used an overt gaze following task to explore age differences in overt gaze following whilst people searched for a target. Participants were faster to detect targets appearing at the looked-at location, and although the gaze cue biased the direction in which saccades were executed, no age differences were found in overt gaze following. There were, however, age effects relating to involuntary eye movements. In the younger adults, anticipatory saccades were biased in the direction of the gaze cue, but this bias was not observed in the older group. Moreover, in the younger adults, saccades that followed the gaze were initiated more rapidly, illustrating the reflexive nature of gaze following. No such difference was observed in the older adults. Importantly, our results showed that whilst the general levels of gaze following were age invariant, there were age-related differences in the reflexive components of overt gaze following.  相似文献

This article addresses the multiple definitions of social class in African American people and how the therapist's understanding of these definitions is important in therapeutic interventions with African American women. The article discusses: (a) the traditional ways in which social class has been defined in social science and the limits of these conceptualizations; (b) the multiple definitions of class within the African American community; and (c) treatment concerns for African American women based on class issues. Clinicians working with African American and other women who vary by class should be able to assess how class variables influence their therapeutic interventions with these women.  相似文献

Recent research findings suggest that reinforcing stimuli may be differentially effective as response requirements increase. We extended this line of research by evaluating responding under increasing schedule requirements via progressive‐ratio schedules and behavioral economic analyses. The differential effectiveness of preferred stimuli in treating destructive behavior maintained by automatic reinforcement also was examined. Results showed that one of two stimuli was associated with more responding under increasing schedule requirements for the 4 participants. Furthermore, stimuli associated with more responding under increasing schedule requirements generally were more effective in treating destructive behavior than stimuli associated with less responding. These data suggest that progressive‐ratio schedules and behavioral economic analyses may be useful for developing a new technology for reinforcer identification. From a clinical perspective, these results suggest that two reinforcers may be similarly effective for low‐effort tasks and differentially effective for high‐effort tasks.  相似文献
