Previous research has shown that 6-month-olds evaluate others on the basis of their social behaviors--they are attracted to prosocial individuals, and avoid antisocial individuals (Hamlin, Wynn & Bloom, 2007). The current studies investigate these capacities prior to 6 months of age. Results from two experiments indicate that even 3-month-old infants evaluate others based on their social behavior towards third parties, and that negative social information is developmentally privileged.  相似文献

Whites in community samples utilize mental health services at a much higher rate than African Americans (Kessler, et al., 2005). Is this also the case among those in jails? In this study of jail inmates (229 African American, 185 White) there were no race difference in the overall need for mental health treatment (63% of participants had significant symptoms on the Personality Assessment Inventory) but race differences in the level and types of symptoms were evident. Additionally, while Whites were more likely to report pre-incarceration treatment there were no differences in treatment seeking or access to mental health programs while in jail, implying that if barriers to treatment in the community were removed (cost/insurance, location/transportation, time) racial disparities in treatment utilization may be reduced.  相似文献

Many theories assume that preknowledge of an upcoming target helps visual selection. In those theories, a top-down set can alter the salience of the target, such that attention can be deployed to the target more efficiently and responses are faster. Evidence for this account stems from visual search studies in which the identity of the upcoming target is cued in advance. In five experiments, we show that top-down knowledge affects the speed with which a singleton target can be detected but not the speed with which it can be localized. Furthermore, we show that these results are independent of the mode of responding (manual or saccadic) and are not due to a ceiling effect. Our results suggest that in singleton search, top-down information does not affect visual selection but most likely does affect response selection. We argue that such an effect is found only when information from different dimensions needs to be integrated to generate a response and that this is the case in singleton detection tasks but not in other singleton search tasks.  相似文献

This study tested the effects of distraction using virtual-reality (VR) technology on acute pain tolerance in young adults. Forty-one undergraduate students, aged 18-23 years, used a VR head-mounted display helmet, steering wheel, and foot pedal to play an auto racing video game while undergoing exposure to very cold water (cold pressor set at 1 °C). Two different game views were tested that were hypothesized to affect the degree to which participants felt "present" in the virtual environment: a first-person view, in which the participant saw the virtual environment through the eyes of the game character being manipulated; and a third-person view, in which the participant viewed the game character from a distance. The length of time participants tolerated the cold-water exposure (pain tolerance) under each distraction condition was compared to a baseline (no distraction) trial. Subjects also rated the degree to which they felt "present" in the virtual environment after each distraction trial. Results demonstrated that participants had significantly higher pain tolerance during both VR-distraction conditions relative to baseline (no distraction) trials. Although participants reported a greater sense of presence during the first-person condition than the third-person condition, pain-tolerance scores associated with the two distraction conditions did not differ. The types of VR applications in which presence may be more or less important are discussed.  相似文献

Abstract. Beginning with a series of questions designed to peak reader curiosity and expose key challenges for mid‐career faculty, the authors uncover several issues in post‐tenure faculty life and work, and they reflect on images for understanding and responding to these challenges. Topics identified include mid‐career as an opportunity for deeper investment in one's teaching, challenges associated with competing claims for time, shifts in research that can accompany the transition to mid‐career, challenges in dealing with an increasing generational gap between oneself and one's students, responsibilities associated with being a longer‐term member of a faculty, and feelings of fatigue and occasional alienation from one's educational institution and/or church.  相似文献

Research has shown that explanations for selection decisions may influence a variety of applicant perceptions and behavior, but an understanding of how and why this occurs remains largely unknown. This study attempts to understand the effects of explanations by adopting Kelley's (1967, 1972) covariation model of the attribution process. Specifically, explanations that vary on consensus, distinctiveness, and consistency covariation information should produce predictable effects on applicant perceptions and attributions. Results from 2 studies, the first a laboratory study and the second a field study with actual applicants, support the utility of the covariation model for understanding the influence of explanations for selection decisions on locus attributions, fairness, self‐perceptions, and organizational attractiveness. These results suggest that the covariation model may be a useful means to construe the explanation‐attribution‐perception relationship, and thus provide a number of theoretical and practical implications.  相似文献

Data from a national online organization that matches volunteers with service organizations places volunteers were analyzed to answer questions regarding the impact of the September 11, 2001, attacks on volunteering in the United States. Results showed that: (a) following September 11, there was a dramatic increase in the number of people who offered to volunteering, and the increase lasted for about 3 weeks; (b) the greatest increase in volunteering occurred for crisis‐related organizations, but volunteering increased significantly for all kinds of charities and service organizations; and (c) the demographic correlates of volunteering changed little in the wake of the attacks. The results are discussed in the context of psychological theories of the factors that motivate prosocial actions.  相似文献

The schema approach to self‐concept was used to investigate the association between body‐weight self‐conception and self‐esteem, negative affect states, and disordered eating behavior in women with anorexia nervosa (n= 26) or bulimia nervosa (N= 53) using experience sampling methodology. We predicted that self‐esteem would be lower and unpleasant affect and disordered eating behaviors would be higher when the body‐weight self‐schema was activated in working memory compared to when non‐weight‐related self‐schemas were activated. Participants recorded the currently activated self‐schema, self‐esteem, affect, and behavior in response to an alarm‐watch signal 5 times daily for 5 days. Activation of the body‐weight self‐schema was associated with lower self‐esteem and higher negative affect, but not higher levels of disordered eating behavior. Low self‐esteem and negative affect, however, were associated with disordered eating behavior. Findings have important implications for treatment of eating disorders.  相似文献

The relationship between the quality of previous work experience with a coworker who was disabled, job‐related expectancies of employees with disabilities, and affective reactions to employees with disabilities was investigated. Data from individuals who had worked with a coworker who was disabled were collected via an Internet‐based survey. The quality of previous experience with coworkers with disabilities predicted job‐related expectancies of employees with disabilities and affective reactions to employees with disabilities. More positive work experiences were associated with more positive expectancies and affective reactions. The relationship between previous experience and affective reactions was mediated by job‐related expectancies. Perceptions of increased job difficulty that were attributed to a coworker who was disabled predicted less positive job‐related expectancies and affective reactions.  相似文献
