In this study, we investigated the perceptions of the life situations, experiences, psychosocial characteristics, and environments of 94 street youth in Bogotá, Columbia. We outlined the implications of our results for developmental theory, psychosocial competence theory, future research, public policy formation, program development, and direct intervention. 相似文献

Motion hyperacuity (phase) thresholds were measured for both lateral and stereoscopic oscillatory motion in both luminance and equiluminant red/green gratings of 2 cycles per degree. Thresholds for lateral chromatic motion did not exhibit the inhibitory fall-off at low temporal frequencies that was found for luminance motion. Phase thresholds for purely chromatic motion were substantially higher than those for luminance gratings, in proportion to the ratio of cone signal modulation, but they could be predicted from the corresponding contrast sensitivities for both types of stimulus. Stereomovement thresholds in luminance gratings showed the stereomovement suppression effect relative to monocular motion sensitivity previously reported for line stimuli, but purely chromatic gratings did not. Together with the lack of an inhibitory fall-off, these results imply that chromatic and luminance motion are processed by different neural pathways, and that the chrominance pathway is capable of supporting a strong percept of stereoscopic motion from purely chromatic gratings. 相似文献

Reliable taste detection thresholds in humans are difficult to obtain for either research or clinical purposes because ordinary taste stimuli cannot be generated and presented by means of a computer. However, in investigations of taste dysfunction, electrical taste stimulation (electrogustometry) is sometimes employed. Minute anodal direct currents are applied manually to the tongue, giving rise to an acid taste experience through the liberation of protons into the saliva. This experience accords with recent findings on the mechanisms underlying sour taste perception. The device described here is a safe and accurate constant-current device, operating under computer control at very low amperages, making it possible to apply modern psychophysical procedures to the measurement of evoked taste thresholds. 相似文献

Communities are increasingly being required by state and federal funders to achieve outcomes and be accountable, yet are often
not provided the guidance or the tools needed to successfully meet this challenge. To improve the likelihood of achieving
positive outcomes, the Getting To Outcomes (GTO) intervention (manual, training, technical assistance) is designed to provide
the necessary guidance and tools, tailored to community needs, in order to build individual capacity and program performance.
GTO is an example of a Prevention Support System intervention, which as conceptualized by the Interactive Systems Framework,
plays a key role in bridging the gap between prevention science (Prevention Synthesis and Translation System) and prevention
practice (Prevention Delivery System). We evaluated the impact of GTO on individual capacity and program performance using
survey- and interview-based methods. We tracked the implementation of GTO and gathered user feedback about its utility and
acceptability. The evaluation of GTO suggests that it can build individual capacity and program performance and as such demonstrates
that the Prevention Support System can successfully fulfill its intended role. Lessons learned from the implementation of
GTO relevant to illuminating the framework are discussed. 相似文献

ABSTRACT In 4 studies we examine the association between narcissism, self-construal, and cognitive–perceptual style, hypothesizing that high self-focus in combination with low other-focus (i.e., social atomization) is related to an analytic cognitive–perceptual style. Participants completed the Narcissistic Personality Inventory, the Self-Construal Scale, and measures of cognitive–perceptual style such as the Analysis-Holism Scale, the Embedded Figures Test, a visual illusion test, and a measure of the representativeness heuristic. We found evidence for a decontextualized cognitive–perceptual style in socially atomized participants, which included those high in narcissism and also those who had a combination of high independent and low interdependent self-construal. A meta-analytic integration of our findings found that narcissism was positively related to independent and negatively related to interdependent self-construal, and mediation analyses found some evidence that the relationship between self-construal and cognitive–perceptual style is partially mediated by narcissism. 相似文献

The current research examines observer reactions to disrespectful treatment of another ingroup member by an ingroup authority. In an empirical study which identifies both the moderating and mediating role of group identification in tandem, specifically with regard to the observed intragroup disrespect, relational motives appeared to underlie subsequent observer evaluations of the group as a whole. Respondents' pre‐transgression identification with the group in which the injustice occurred moderated reactions to intragroup disrespect; only when group members identified strongly with the group did they react to more severe disrespect with worse evaluations. Group identification also mediated the impact of disrespect on subsequent reactions toward the group. Additionally, the relationship between observed disrespect severity and post‐transgression identification with the group was further mediated by perceptions of membership value in the group.

Four studies (N = 643) supported the hypothesis that social exclusion would reduce the global perception of life as meaningful. Social exclusion was manipulated experimentally by having a confederate refuse to meet participants after seeing their videotaped introduction (Study 1) and by ostracizing participants in a computerized ball-tossing game (Study 2). Compared to control condition and acceptance conditions, social exclusion led to perceiving life as less meaningful. Exclusion was also operationalized as self-reported loneliness, which was a better predictor of low meaning than other potent variables (Study 3). Study 4 found support for Baumeister’s model of meaning (1991), by demonstrating that the effect of exclusion on meaning was mediated by purpose, value, and positive self-worth. 相似文献

The present research examined the effect of procedural fairness and trust in an authority on people's willingness to cooperate with the authority across a wide range of social situations. Prior research has shown that the presence of information about whether an authority can be trusted moderates the effect of procedural fairness. If no trust information is available, procedural fairness influences people's reactions. This is not the case when information about the trustworthiness of the authority is present. In the present article, it is argued that information about whether the authority can or cannot be trusted may also moderate the effect of procedural fairness in predicting levels of cooperation. Assuming that the use of fair procedures by authorities that cannot be trusted is less influential than is the enactment of procedures by trustworthy authorities, it is predicted that trust in authority moderates the influence of procedural fairness on cooperation in such a way that procedural fairness has a positive effect on cooperation primarily when trust in authority is high. Results from 4 studies (2 experimental studies and 2 field studies) provide supportive evidence for this interaction. 相似文献
