Data from the in-school survey of the National Longitudinal Study of Adolescent Health on girls and boys who claim a Mexican, Puerto Rican, or Cuban heritage were employed to test two hypotheses: (1) Participating in a school-based sport is associated with self-esteem, and (2) school attachment and a sense of physical well-being mediate this relationship. The first hypothesis was partially confirmed in that participation in school sports was associated with self-esteem among Mexican American adolescent girls and boys, Puerto Rican girls, and Cuban American boys, but not among Cuban American girls nor Puerto Rican boys. The second hypothesis was confirmed in that, where there was a significant relationship between participating in a school sport and self-esteem, school attachment and physical well-being mediated this relationship. The results underscore the need to study psychosocial processes separately among Latino subgroups and to examine gender within each subgroup.  相似文献

Inhibition of return (IOR) refers to slower reaction times when a target appears unpredictably in the same location as a preceding cue, rather than in a different location. In the present study, frontal images of human faces were presented intact as face configurations, were rearranged to produce scrambled-face configurations, or were pixilated and randomized to produce nonface configurations. In an orienting paradigm designed to elicit IOR, face and scrambled-face stimuli were used as cues (Experiment 1), as targets (Experiment 2), or along with pixilated nonface stimuli as both cues and targets (Experiment 3). The magnitude of IOR for subsequent localization targets was unaffected by cue configuration. Likewise, the magnitude of IOR was unaffected by target configuration. These results suggest that IOR is a "blind" mechanism that is unaffected by the mere occurrence of biologically relevant cue and target stimuli.  相似文献

We examined the relation between child maltreatment and non-suicidal self-injury (NSSI). Participants were 86 adolescents who completed measures of child maltreatment, self-criticism, perceived criticism, depression, and NSSI. Analyses revealed significant, small-to-medium associations between specific forms of child maltreatment (physical neglect, emotional abuse, and sexual abuse) and the presence of a recent history of NSSI. Emotional and sexual abuse had the strongest relations with NSSI, and the data supported a theoretical model in which self-criticism mediates the relation between emotional abuse and engagement in NSSI. Specificity for the mediating role of self-criticism was demonstrated by ruling out alternative mediation models. Taken together, these results indicate that several different forms of childhood maltreatment are associated with NSSI and illuminate one mechanism through which maltreatment may be associated with NSSI. Future research is needed to test the temporal relation between maltreatment and NSSI and should aim to identify additional pathways to engagement in NSSI.  相似文献

Moral text processing was used as an ecologically valid method for assessing implicit and explicit moral understanding and development. The authors tested undergraduates, seminarians, and graduate students in political science and philosophy for recall of moral narratives and moral expository texts. Multivariate analyses of covariance using educational experience as an independent variable, age and moral judgment score as covariates, and recall of embedded moral arguments as a dependent variable revealed a relation between education and level of moral arguments recalled. Lower stage moral reasoning was best recalled by undergraduates, whereas higher stage reasoning was best recalled by graduate students, with seminarians intermediate for both types of text. Moral judgment score was related to recall of the highest level moral arguments even when age and educational experience were controlled. Moral judgment development appeared to be particularly helpful in recall of expository compared with narrative texts.  相似文献

Given women's communally oriented socialization and social pressures to find romantic partners, many heterosexual women may derive self-worth from having romantic relationships (relationship contingency). Across two studies, we explored whether relationship contingency heightens women's body shame. Studies 1A and 1B found that relationship contingency causes body shame among women. In Study 2, relationship contingency predicted greater bulimic symptoms, which was mediated fully by greater body shame. Using both experimental methods and structural equation modeling, these studies demonstrate a link between relationship contingency and body shame that is not explained by appearance contingency (basing self-esteem on one's physical appearance). Results are discussed in terms of self-objectification theory, contingencies of self-worth, mate preferences, and close relationships.  相似文献

Neural control of behavior: countermanding eye movements   总被引:4,自引:0,他引:4  
Understanding the self-control of action entails knowledge about how actions are initiated, how planned actions are canceled and how the consequences of actions are registered. We have investigated neural correlates of these processes using the countermanding paradigm – a task that required subjects to occasionally cancel a planned speeded response, and an analysis that provides an estimate of the time needed to cancel a planned movement. By monitoring the activity of single neurons in the frontal cortex of macaque monkeys performing this task we have distinguished signals responding to the visual stimuli, other signals that control the production of movements, and still other signals that seem to monitor behavior.

This study is an investigation of the effectiveness of an individually administered mood induction procedure compared with an equivalent procedure administered to a group. Seventy-nine nondepressed individuals (25 men, 54 women) were randomly assigned to either a depressive or a neutral mood induction in an individual or a group setting. In each procedure, the mood induction involved the Velten self-statement procedure (E. Velten, 1968) enhanced by related mood music. Overall, both the individual and group induction procedures were effective in producing a depressed mood state, and their effectiveness was unrelated to social desirability or the sex of the participant. However, the group procedure was more vulnerable to individual differences in response, and its use in research on depression requires stringent criteria for mood change.  相似文献

This report describes some recent examinations of the ability of aphasic patients to construct syntactically governed dependency relations in real time. The data show that Wernicke's patients can link the elements of dependency relations in the same way as neurologically intact subjects, even for sentences that they do not understand. Broca's patients, by contrast, are shown to be unable to create such links, even for sentences that they do understand. These data underline the isolability of this stage of syntactic analysis and they suggest that comprehension limitations statable in syntactic terms can be traced to changes in cortically localizable processing resources.  相似文献

The purposes of this study were to examine young adolescent functioning over a 2-year period after divorce and to assess the role of two family factors, interpersonal conflict and the parent-adolescent relationship, in predicting such functioning. One hundred and twelve young adolescents, their mothers, and their social studies teachers served as participants. One-half of the adolescent were from recently divorced families and one-half were from married families. Mothers completed measures concerning interparental conflict and the parent-adolescent relationship, adolescents completed a measure of the relationship, and teachers completed measures assessing four areas of adolescent functioning. The results indicated that adolescents from divorced families were functioning less well than those from married families. There were no changes in adolescent functioning and the parent-adolescent relationship from the first to second year postdivorce. High levels of interparental conflict in divorced families were associated with more parent-adolescent relationship problems. In turn parent-adolescent relationships problems served as the best predictor of concurrent and subsequent difficulty in adolescent functioning.This study was supported, in part, by the William T. Grant Foundation and the University of Georgia's Institute for Behavioral Research.  相似文献
