After the swim to cycle transition of a triathlon, perceived exertion (RPE) during cycling was higher than during a single cycling bout for 8 well-trained triathletes, but swimming in a drafting position led to lower RPE responses and energy cost of cycling than swimming alone. 相似文献

Major biases and stereotypes in group judgments are reviewed and modeled from a recurrent connectionist perspective. These biases are in the areas of group impression formation (illusory correlation), group differentiation (accentuation), stereotype change (dispersed vs. concentrated distribution of inconsistent information), and group homogeneity. All these phenomena are illustrated with well-known experiments, and simulated with an autoassociative network architecture with linear activation update and delta learning algorithm for adjusting the connection weights. All the biases were successfully reproduced in the simulations. The discussion centers on how the particular simulation specifications compare with other models of group biases and how they may be used to develop novel hypotheses for testing the connectionist modeling approach and, more generally, for improving theorizing in the field of social biases and stereotype change. 相似文献

One goal of this paper is to present an integrated tripartite model of violence, with a focus on structural violence within an oppression paradigm. Using qualitative and quantitative data from 27 women (70% African American and 30% European American) who participated in a national substance abuse treatment demonstration program, we describe a model of violence in which structural violence is presented within a transactional relationship with interpersonal, and intrapersonal violence. We suggest that the effects of structural, interpersonal, and intrapersonal violence are magnified when race and poverty are considered. The second goal of the paper is to present a preliminary test of the new model of violence. Results indicated that different levels and types of violence are interrelated. Implications of these findings for empowering solutions are suggested. 相似文献

Underemployment in America: Measurement and Evidence 总被引:4,自引:0,他引:4
An important way in which employment hardship has come to be conceptualized and measured is as underemployment. Underemployment goes beyond mere unemployment (being out of a job and looking for work), to include those who have given up looking for work, part-time workers whose employer(s) cannot give them full-time work, and the working poor. To provide needed background for the other articles in this special issue, we trace the history of the concept of underemployment, review existing empirical literature, offer a critique of the measurement of underemployment as conventionally operationalized, and provide up-to-date evidence on the trends and correlates of underemployment in the United States. 相似文献

Listening comprehension and working memory are impaired in attention-deficit hyperactivity disorder irrespective of language impairment 总被引:9,自引:0,他引:9
McInnes A Humphries T Hogg-Johnson S Tannock R 《Journal of abnormal child psychology》2003,31(4):427-443
This study investigated listening comprehension and working memory abilities in children with attention-deficit hyperactivity disorder (ADHD), presenting with and without language impairments (LI). A 4-group design classified a community sample (n = 77) of boys aged 9–12 into ADHD, ADHD + LI, LI, and Normal groups. Children completed tests of basic language and cognitive skills, verbal and spatial working memory, and passage-level listening comprehension. Multivariate analyses and post hoc comparisons indicated that ADHD children who did not have co-occurring LI comprehended factual information from spoken passages as well as normal children, but were poorer at comprehending inferences and monitoring comprehension of instructions. ADHD children did not differ from normal children in verbal span, but showed significantly poorer verbal working memory, spatial span, and spatial working memory. The ADHD + LI and LI groups were most impaired in listening comprehension and working memory performance, but did not differ from each other. Listening comprehension skills were significantly correlated with both verbal and spatial working memory, and parent–teacher ratings of inattention and hyperactivity/impulsivity. Findings that children with ADHD but no LI showed subtle higher-level listening comprehension deficits have implications for both current diagnostic practices and conceptualizations of ADHD. 相似文献

Experiment 1 indicated that when the White supervisor's negative treatment of a Black subordinate was unconstrained, participant race had no impact on attributions. Conversely, when the treatment was constrained, Black participants reported greater racist attributions than did White participants. Experiment 2 indicated that when the supervisor reported no response or a minimal negative response (i.e., indicating that he did not support his actions) after his negative treatment of the Black subordinate, Black participants reported greater racist attributions than did White participants. Conversely, when the supervisor's negative treatment was followed by a more extreme negative response, participant race had no impact on attributions. Experiment 3 indicated that Black participants were less likely than White participants to perceive a minimal negative response as reflecting a White supervisor's lack of support for his negative actions. Conversely, participant race had no impact on attributions of a Black supervisor's negative actions. 相似文献

Two studies examined perceptions of collective responsibility for the April 20, 1999, shootings at Columbine High School in Littleton, Colorado. Collective responsibility refers to the perception that others, besides the wrongdoers themselves, are responsible for the event. In Study 1, the authors assessed perceptions of the shooters' parents and their peer group (the Trenchcoat Mafia), whereas Study 2 tested perceptions of collective responsibility across a range of groups. In both studies, perceptions of a target group's entitativity predicted judgments of collective responsibility. This relationship was mediated by two situational construals that justify applying collective responsibility: responsibility by commission (encouraging or facilitating the event) and responsibility by omission (failing to prevent the event). Study 2 also determined that perceptions of authority predicted judgments of collective responsibility for the Columbine shootings and was mediated by inferences of omission. Future directions in collective responsibility research are discussed. 相似文献

The specificity of the right hemisphere (RH) contribution to the semantic processing of words is still debated. Indeed, the semantic impairments of right hemisphere damaged (RHD) subjects may be the expression of limited general cognitive resources rather than a specific impairment of semantic processing ([Monetta et al., 2001]; [Murray, 2000]). The purpose of this study was to evaluate the possibility that the N400 reflect the availability of cognitive resources through an analysis of its different amplitudes according to different semantic complexity level. Ten young adults without any history of neurological damage participated in a semantic categorization task with two different levels of difficulty based on prototypicality. Event related potential (ERP) signals from 64 electrodes were recorded. An N400 was observed during the processing of difficult words and distractors. The results show that the greatest N400 activation was observed during the processing of difficult words, thus reflecting a possible increase in the amount of required cognitive resources. 相似文献
