Researchers previously have investigated the role of race in capital sentencing, and in particular, whether the race of the defendant or victim influences the likelihood of a death sentence. In the present study, we examined whether the likelihood of being sentenced to death is influenced by the degree to which a Black defendant is perceived to have a stereotypically Black appearance. Controlling for a wide array of factors, we found that in cases involving a White victim, the more stereotypically Black a defendant is perceived to be, the more likely that person is to be sentenced to death. 相似文献

Enhancing the transfer of computer-assisted training proficiency in geographically distributed teams
The authors examined factors that determine whether knowledge gained from computer-assisted (i.e., technology-based) team training in a geographically distributed team (GDT) context transfers to organizational results. They examined the moderating effects of team trust, technology support, and leader experience on the relation between teams' average individual training proficiency on a computer-assisted (i.e., CD-ROM-based) training program and team performance as assessed by team customer satisfaction ratings. Using data collected from 40 GDTs in a high-technology company, the authors found that the relation between teams' average training proficiency and team performance was complex and moderated by several factors. In particular, teams' average training proficiency had a positive association with customer satisfaction when GDTs were higher, rather than lower, in both trust and technology support and when team leaders had longer, rather than shorter, levels of tenure with their specific team. 相似文献

Younger and older African American and Caucasian American adults, who were matched by age (M age = 40.63 years), completed a survey on perceptions of aging and subjective age. The 2 groups did not differ in the age they considered someone to be old (M age = 74.5 years). However, when asked which age was the happiest age, African Americans chose a significantly younger age (M age = 18.26 years) than did Caucasian Americans (M age = 31.32 years), and this racial group difference interacted with age differences such that older Caucasian Americans named an older age than did younger Caucasian Americans. The authors found no such age difference for African Americans. When asked if old age was a happy time, 60% of Caucasian Americans answered yes, whereas only 2% of African Americans answered yes. These and other differences in images and concerns of old age and subjective age suggest a far more negative view of aging for African Americans and a need for changes in the provision of positive information about aging for this group. 相似文献

The authors interviewed a random sample of 306 university faculty as part of an annual university poll. Items focused on air travel concerns following 9/11, positive aspects of travel, and future travel intentions. Demographic factors were not significant predictors for men or women faculty. Faculty expressed positive attitudes toward travel, for example agreeing that travel allows them to demonstrate competency. Concerns about missing connections and delays elicited a larger percent of negative reactions than concerns about hijackings or security. Gender differences were not observed on individual items, but in regression analyses a composite of self-reported travel risk factors was more predictive of future travel plans for women than for men, although women expected to travel as much in the future as men. The results are consistent with positive psychology and speak to applied aspects of travel and tourism. 相似文献

The Roelofs effect is a distortion of perceived space that occurs when a large frame whose center is offset left or right from the objective midline is presented visually to an observer and causes a bias in the observer's subjective judgment of midline. Experiments were designed to test whether an isolated fragment (left or right end) of a Roelofs-inducing frame was capable of generating the Roelofs effect and to determine whether prior experience with intact frames would provide a top-down influence that would bias the Roelofs effect resulting from fragment presentation. Although the fragments did induce an effect, top-down information did not play a significant role even after a 5-day training paradigm. Instead, we found that the effect generated by an intact frame was equal in magnitude to the sum of the effects generated by the individual fragments. In addition, perception was found to be differentially affected by the two ends of the frame, with fragments falling in the right visual field causing a larger effect than those falling in the left. 相似文献

Semantic priming refers to a reduction in the reaction time to identify or make a judgment about a stimulus that has been immediately preceded by a semantically related word or picture and is thought to result from a partial overlap in the semantic associates of the two words. A semantic priming lexical decision task using spoken words was presented in event-related fMRI and behavioral paradigms. Word pairs varied in terms of semantic relatedness and the connectivity between associates. Thirteen right-handed subjects underwent fMRI imaging and 10 additional subjects were tested in a behavioral version of the semantic priming task. It was hypothesized priming would be greatest, reaction time fastest, and cortical activation reduced the most for related word pairs of high connectivity, followed by related word pairs of low connectivity, and then by unrelated word pairs. Behavioral and fMRI results confirmed these predictions. fMRI activity located primarily in bilateral posterior superior and middle temporal regions showed modulation by connectivity and relatedness. The results suggest that these regions are involved in semantic processing. 相似文献

The aim of this study was to determine whether Hebrew readers reference phonological information for the silent processing of unpointed Hebrew nouns. A research paradigm in which participants were required to perform consecutive same/different judgments regarding the identicalness of members of stimulus pairs was used for answering this question. Twenty-eight students (mean grade 4.9) participated in the study. The nouns used in preparing the word stimulus pairs were comprised of various amounts of syllabic information (monosyllabic versus bisyllabic) and differed in the degree this information was represented by their letter graphemes. The main findings suggest that the processing of the identicalness of unpointed Hebrew words may not involve the referencing of their phonological information. 相似文献

A national survey was administered in 1993-1994 (N = 360) and repeated in 2001 (N = 435) to assess the prevalence of homelessness as well as attitudes, opinions and knowledge regarding homelessness. No significant changes in prevalence were found, despite a strong US economy during most of the 7-8 year period. Respondents in 2001 had less stereotyped views of homeless people and were more supportive of services, but came to see homelessness as a less serious problem that was less often due to economic factors. This "mixed" set of findings may reflect both beliefs on the benefits of a good economy and an increased awareness of the complexity of homelessness. Across the surveys, younger, female, liberal, and less wealthy respondents demonstrated more sympathetic attitudes towards homeless people. 相似文献

Acculturation and Aggression in Latino Adolescents: A Structural Model Focusing on Cultural Risk Factors and Assets 总被引:1,自引:0,他引:1
The specific aim of this investigation was to map cultural factors associated with aggressive behavior in Latino adolescents. Interviews were conducted with a sample of 481 foreign- and U.S.-born Latino adolescents living in North Carolina and Arizona. Structural Equation Modeling was used to validate a conceptual model linking adolescent and parent culture-of-origin and U.S. cultural involvement, acculturation conflicts, and perceived discrimination to family processes (familism and parent-adolescent conflict) and adolescent aggression. Parent-adolescent conflict was the strongest cultural risk factor followed by perceived discrimination. Familism and adolescent culture-of-origin involvement were key cultural assets associated with less aggressive behavior. Exploratory mediation analyses suggested that familism and parent-adolescent conflict mediated the effects of acculturation conflicts, parent and adolescent culture-of-origin involvement, and parent U.S. cultural involvement on adolescent aggression. Implications for prevention programming were discussed. 相似文献
