The influence of emotional prosody on the evaluation of emotional facial expressions was investigated in an event-related brain potential (ERP) study using a priming paradigm, the facial affective decision task. Emotional prosodic fragments of short (200-msec) and medium (400-msec) duration were presented as primes, followed by an emotionally related or unrelated facial expression (or facial grimace, which does not resemble an emotion). Participants judged whether or not the facial expression represented an emotion. ERP results revealed an N400-like differentiation for emotionally related prime-target pairs when compared with unrelated prime-target pairs. Faces preceded by prosodic primes of medium length led to a normal priming effect (larger negativity for unrelated than for related prime-target pairs), but the reverse ERP pattern (larger negativity for related than for unrelated prime-target pairs) was observed for faces preceded by short prosodic primes. These results demonstrate that brief exposure to prosodic cues can establish a meaningful emotional context that influences related facial processing; however, this context does not always lead to a processing advantage when prosodic information is very short in duration.  相似文献

Interaction between the cerebral hemispheres may allow both hemispheres to contribute their processing resources in order to cope efficiently with complex tasks [Banich, M. (1998). The missing link: the role of interhemispheric interaction in attentional processing. Brain and Cognition, 36, 128-157]. The current study investigated whether the benefits of interhemispheric interaction arise because of top-down knowledge about the task built up over the course of a block of trials or because of the processing demands present in a single trial. Participants performed a less computationally complex physical identity task and a more complex adding task on within-visual field and across-visual field trials. Task differences in interhemispheric interaction were compared between the blocked and mixed conditions to investigate whether frequent task switches altered the pattern of interhemispheric resource recruitment. A similar interaction between task difficulty and trial type (across- or within-visual field presentation) was obtained for both the blocked and mixed conditions. The degree of task-dependency of interhemispheric interaction was not altered in the mixed condition. This finding supports the view that interhemispheric interaction becomes beneficial in response to the processing demands of an individual trial rather than as a result of top-down task knowledge.  相似文献

The Satisfaction with Travel Scale (STS) has recently been developed to measure people’s satisfaction with travel. It supposedly consists of two affective and one cognitive dimension. As there have only been a few tests of its reliability and structure to date, this paper reports new tests using data on leisure trips from Ghent (Belgium). Differences in the reliability and structure of the STS by transport mode – car, public transport, bicycling and walking – are also considered. Overall, the results suggest that the specification of a single underlying dimension for affect rather than two offers a superior fit to the Ghent data, both for all modes combined and for car use and cycling separately. For public transport and walking a three-dimensional structure is more appropriate although individuals items do not load on the two affective dimensions as expected. Differences between previous studies and ours are partly caused by differences in how two of the scale’s items – alert/tired and confident/worried – are correlated with the other items. Future studies using the STS may want to adapt the structure of STS by omitting some items or replacing them with alternatives as this may reduce respondent burden and increase internal consistency of the STS.  相似文献

In this study, the effects of autonomy values and funding constraints on individual norms concerning merit pay decisions were examined. Policy-capturing regressions were performed on 72 students' answers to a pay-planning exercise. These regressions produced coefficients that described the participants' norms concerning the allocation of merit pay raises. Hierarchical analyses of variance showed that autonomy values had a significant and sizable effect on individual pay-for-performance norms. Results suggest that the administration of merit pay systems and future field studies should recognize that measuring individual values will help to explain the diversity of individual responses to the same merit pay system.  相似文献

This research examined how efforts to ensure demographic diversity in a work group affected perceptions of the competence of individuals who are likely targets of such efforts. In three experiments, 262 undergraduates gave their impressions and performance expectations of members of a group assembled to work on a task. When a diversity rationale rather than a merit rationale was provided for how the work group was assembled, both women (Studies 1 and 2) and Black men (Study 3) were perceived as less competent and were expected to be less influential. This effect occurred regardless of the proportional representation of women or the degree of the groups' heterogeneity. The diversity rationale also produced more negative characterizations than did another non‐merit‐based rationale: scheduling convenience.  相似文献

Research on the effects of adolescent employment on primarily middle‐class youth suggests that intense employment, working more than 15 or 20 hours during the school year, is associated with increased participation in risky behavior. Despite these findings, scholars who focus on the development of youth living in low‐income urban areas often hypothesize that adolescent employment will have beneficial effects on this population. There is some evidence that adolescent employment is associated with increased educational achievement and adult employment for low‐income urban youth. The impact of adolescent employment on future engagement in risky behavior across levels of neighborhood deprivation and employment intensity was investigated on a sample of 1,057 adolescents from the Project on Human Development in Chicago Neighborhoods, a longitudinal study of neighborhood effects on development. After controlling for individual characteristics, intense employment during adolescence did predict increased use of cigarettes and alcohol and having a greater number of sexual partners 2 years after employment was measured. There were no significant interactions between neighborhood SES and adolescent employment status on involvement in risky behavior. These findings suggest that intense adolescent employment is associated with detrimental developmental outcomes for youth regardless neighborhood context.  相似文献

Neighborhood characteristics have been shown to impact child well-being. However, it remains unclear how these factors combine with family characteristics to influence child development. The current study helps develop that understanding by investigating how neighborhoods directly impact child and adolescent behavior problems as well as moderate the influence of family characteristics on behavior. Using multilevel linear models, we examined the relationship among neighborhood conditions (poverty and social capital) and maternal depression on child and adolescent behavior problems. The sample included 741 children, age 5–11, and 564 adolescents, age 12–17. Outcomes were internalizing (e.g. anxious/depressed) and externalizing (e.g. aggressive/hyperactive) behavior problems. Neighborhood poverty and maternal depression were both positively associated with behavior problems for children and adolescents. However, while neighborhood social capital was not directly associated with behavior problems, the interaction of social capital and maternal depression was significantly related to behavior problems for adolescents. This interaction showed that living in neighborhoods with higher levels of social capital attenuated the relationship between maternal depression and adolescent behavior problems and confirmed the expectation that raising healthy well-adjusted children depends not only on the family, but also the context in which the family lives.  相似文献

The current research suggests that perceptions of stranger harassment experiences (i.e., experiencing unwanted sexual attention in public) are altered by the context of the situation. Study one investigated which elements of the situation (context) might be most influential in increasing fear and enjoyment of the catcalling experience. Attractiveness and age of the perpetrator, time of day, and whether the victim was alone or with friends were some of the categories that were selected as influencing both fear and enjoyment. Study two used a perspective taking methodology to ask women to predict a target character’s emotions, fears, and behaviors in harassment situations that varied by context. Results mirror the sexual harassment literature and suggest that harassment by younger and attractive men is viewed as less harassing. Exploratory analyses were also conducted with women’s personal experiences with stranger harassment as well as gender differences in perceptions. Context plays a vital role in interpretation of stranger harassment.  相似文献

The current study adopts an intervention approach that begins with the assumption that the quality of a person’s lived experience is at the core of well-being and health behavior change. Specifically, the present study used a well-being enhancement process grounded in eudaimonia to explore the connection among eudaimonia, indicators of psychological well-being (i.e., personal growth, subjective vitality, self-determination, and life engagement), and physical activity. Participants in the intervention group engaged in 8 weekly, group eudaimonic well-being enhancement (the Well-Being Way, WBW) sessions with assessments at Weeks 1, 8, and 12 (follow-up), and were compared to a comparison group that did not participate. A series of 2?×?3 (Group by Time) repeated measures ANOVAs along with follow-up paired comparisons t-tests were conducted to compare the WBW and comparison groups across time. Results indicated that the WBW group exhibited significant increases in two indices of psychological well-being (trait subjective vitality and self-determination) and in their physical activity levels. The comparison group showed no changes in any of the variables. The results of an exploratory regression analysis provided some evidence that WBW participants who experienced the greatest gains in life engagement and trait subjective vitality also exhibited significant increases in level of physical activity. Discussion focuses on the implications of the Well-Being Way approach for the enhancement of positive well-being and future possibilities for eudaimonic-based approaches to health behavior change.  相似文献

One hundred fifty-five men and 233 women, aged 20 to 79 years, were asked to name both the most wise and the most interpersonally wise persons they knew personally and to give the age and sex of each. Participants were also asked for the areas in which their nominees were particularly wise. Overall, men and women responded similarly. The subjects tended to nominate individuals who were older than they were; the difference between their own age and their nominees' age decreased with increasing age. Subjects nominated males more often than females as wise and this tendency increased with the subjects' age. With the exception of older women, participants nominated females more often than males as interpersonally wise. When asked to report the areas in which their wise nominees were particularly wise, subjects tended to mention specific skill areas (e.g., business or science) for male nominees and interpersonal skill areas for female nominees.Please note that Nancy W.

Most people believe that the future will bring them more good things than bad, and therefore have high hopes for the future (MacLeod et al. Cogn Emot 10:69–85, 1996). However, many patients with mood disorders do not hold this positive belief about the future. At the extreme, low expectations of positive outcomes in the future can lead to feelings of hopelessness (O’Connor et al. Psychol Health Med 5:155–161, 2000). This paper aims to extend the literature on subjective probability of future events, using a mood induction paradigm to examine the effects of transient mood change on perceived likelihood of future events in a non-clinical community sample. Participants rated likelihood of future events from a standardized list and from their own lives. Ratings were made in both normal and experimentally-induced positive or negative mood. Results show that self-generated future events were perceived to be more likely than those from a standardized list, and that negative mood significantly biased perceived likelihood of other-generated future events. Participants rating standardized list events saw positive outcomes as less likely and negative outcomes as more likely in induced negative mood than they did in normal mood. Mood had no effect on ratings of self-generated events. Possible directions for future research are discussed.

In order to assess the accuracy of time-use reports, 80 young adults were observed for 2-hour periods, and were interviewed about their activities by a different person the following day. Two experiments were performed. In the first, three different levels of cognitive enhancement were used to improve recall accuracy. Subjects were 60 California college students, 20 per group. In the second study the maximum enhancement condition was replicated with 20 Guatemalan subjects, similar in age, sex and level of education to the California subjects. Both the accuracy of their recall of specific activities, and the accuracy of their time-duration estimates were calculated. Results indicated that the enhancement conditions in Study 1 significantly increased both the number of activities recalled accurately (from 40 to 63 per cent) and the amount of time accurately recalled (from 58 to 70 per cent). In Study 2 the Guatemalans recalled 60 per cent of their activities accurately, and recalled as much time accurately as the Californians. The Guatemalans were significantly more likely to underestimate their time. In other words, when they made errors, these were almost always underestimations. Most of the recall error could be accounted for by forgetting an activity altogether, rather than by estimating its time inaccurately.  相似文献

Leadership theory has long sought to find traits associated with effective leadership. This study uses the five-factor model of personality to investigate the relationship between the personality of supervisors and aggregated attitudes of subordinates. Results from 131 supervisors and 467 subordinates support the notion that supervisor personality is related to subordinate attitudes. Overall, high levels of supervisor Agreeableness, Emotional Stability and Extraversion, plus low levels of Conscientiousness are related to subordinate ratings of satisfaction with supervisor, overall satisfaction, affective commitment and turnover intentions. However, the relationships are somewhat weak and differ across specific criteria. Implications for these findings are discussed.  相似文献

Embodied views of cognition argue that cognitive processes are influenced by bodily experience. This implies that when people make spatial judgments about human bodies, they bring to bear embodied knowledge that affects spatial reasoning performance. Here, we examined the specific contribution to spatial reasoning of visual features associated with the human body. We used two different tasks to elicit distinct visuospatial transformations: object-based transformations, as elicited in typical mental rotation tasks, and perspective transformations, used in tasks in which people deliberately adopt the egocentric perspective of another person. Body features facilitated performance in both tasks. This result suggests that observers are particularly sensitive to the presence of a human head and body, and that these features allow observers to quickly recognize and encode the spatial configuration of a figure. Contrary to prior reports, this facilitation was not related to the transformation component of task performance. These results suggest that body features facilitate task components other than spatial transformation, including the encoding of stimulus orientation.  相似文献

Knowledge about the etiology of Autism Spectrum Disorders (ASDs) is increasing, but causes remain elusive for most cases. Genetic counselors are positioned to help families that have children with ASDs despite uncertainty regarding etiology. To determine how genetic counselors might best provide services, an anonymous survey was conducted with 255 parents whose children were diagnosed on the autism spectrum. Questions concerned: 1) their perceptions of ASD cause(s) and 2) recurrence risk, 3) whether perceived risk affected family planning decisions, 4) whether parents had received genetic services, and 5) how genetic counselors might assist families. The most prevalent perceived cause was genetic influences (72.6%). Most parents’ recurrence risk perceptions were inaccurately high and significantly affected family planning. Only 10% had seen a genetic professional related to an ASD. Parents provided several suggestions for genetic counselor best practices. Findings indicate the importance of genetic counselor awareness of parent perceptions in order to best help families who have children with ASDs.  相似文献

Results from empirical studies on the role of religiosity and spirituality in dealing with stress are frequently at odds, and the present study investigated whether level of religiosity and spirituality is related to the way in which religious coping is used relative to other coping strategies. A sample of 616 university undergraduate students completed the Brief COPE (Carver in Int J Behav Med 4:92?C100, 1997) questionnaire and was classified into groups of participants with lower and higher levels of religiosity and spirituality, as measured by the WHOQOL-SRPB (WHOQOL-SRPB Group in Soc Sci Med 62:1486?C1497, 2006) instrument. For participants with lower levels, religious coping tended to be associated with maladaptive or avoidant coping strategies, compared to participants with higher levels, where religious coping was more closely related to problem-focused coping, which was also supported by multigroup confirmatory factor analysis. The results of the present study thus illustrate that investigating the role of religious coping requires more complex approaches than attempting to assign it to one higher order factor, such as problem- or emotion-focused coping, and that the variability of findings reported by previous studies on the function of religious coping may partly be due to variability in religiosity and spirituality across samples.  相似文献

Although most scholars find that religious involvement is negatively related to depression, questions still remain regarding how individuals benefit from such involvement and evidence from nationally representative samples is rare. In this paper, I expand upon previous research by considering three types of general religious involvement (attendance at religious services, religious salience, and spiritual help-seeking) and three types of effects (linear, curvilinear, and stress-buffering). Using Americans' Changing Lives (House 1989)—a large, nationally representative, and longitudinal data set—I find a U-shaped effect of religious salience on depression, no significant independent effect of service attendance, and a positive effect of spiritual help-seeking. I also find that spiritual help-seeking and religious salience exhibit significant stress-buffering effects, but that these occur only when individuals experience multiple negative life events, and not when they experience any single type of discrete event. The theoretical implications of these effects are discussed, both as they contribute to research on the life stress paradigm and research on the psychology of religion.  相似文献

Empathy is an important psychological concept influencing social interaction. However, knowledge about its etiological components is still scarce. Estimates for the heritability of empathy range between 0 and 70 % depending on the sample, method of measurement, and level of aggregation. In this study, we investigated the heritability of empathy using an extended twin design. We employed the self-report questionnaire Interpersonal Reactivity Index and an emotion recognition task (Reading the Mind in the Eyes Test). N = 742 twins and non-twin siblings were investigated. For affective empathy and the behavioral paradigm, we found heritability estimates between 52 and 57 %. For cognitive empathy, genetic variance was smaller (27 %), indicating that the heritability of empathy depends on the measured subcomponent, which could be relevant for intervention programs like empathy or compassion trainings. Environmental influences on empathy are mainly effects of non-shared environment, which is an important finding for our understanding of the development of empathy.  相似文献

A questionnaire about how academic performance is evaluated and the importance of teaching and research was completed by 265 faculty at a UK research university. Factor analysis followed by t-tests showed that male faculty had a more realistic understanding of how their research is evaluated, rate the importance of research to their careers more highly, and are more likely than women to work over hours through choice. Women faculty are more likely than men to work over hours because of teaching workload and rate the importance of a teaching qualification more highly, despite giving similar ratings as men to the importance of teaching to their career. The implications for differential rates of promotion are discussed.  相似文献
