Previous studies (for example, Bregman & Killen, 1999; Eccles, Wigfield, & Schiefele, 1998; Jacobs, 1991;Jacobs & Eccles, 2000) have demonstrated the important role that parents' attitudes play in shaping their children's later self-perceptions and achievement behaviors. Studies indicate that in the math and science arena, parents' perceptions of their children's abilities as well as their own values about math and science are related to their children's later self-perceptions and values for achieving in these domains. The previous work suggests that parents are conveying their attitudes and values about math to their children through their words and actions; however, little research has documented the ways in which parents' beliefs and specific behaviors might promote positive achievement attitudes and behaviors in their children. The goal of the study reported here was to document relations between parents' math and science--promotive behaviors and attitudes and their children's later activity choices, values, and achievement in these subjects. 相似文献

Body dissatisfaction in married women: the role of spousal influence and marital communication patterns 总被引:1,自引:1,他引:0
Family factors and the media have been established as determinants of body satisfaction, yet little research has looked at the contribution of spousal influence in body dissatisfaction. Marital quality and satisfaction can be a protective factor in the health of women, while high rates of criticism have been associated with poorer health outcomes. The present study investigated the relationship between perceptions of family and spousal factors and body dissatisfaction in married women. Additionally, the impact of marital communication was investigated. Seventy-seven married women completed self-report questionnaires assessing familial body-focused comments, spousal evaluation of a wife’s body, marital communication patterns, and body dissatisfaction. After controlling for weight status, women’s perceptions of familial body-focused comments and spousal evaluation emerged as significant predictors of body dissatisfaction. It was also found that more destructive communication patterns moderated the effect of perceived spousal evaluation on body dissatisfaction. This study provides some context for understanding the impact of specific influences on women’s body dissatisfaction. 相似文献

The philosophy guiding evidence-based treatment and its application to decision-making in stuttering treatment is described. Limitations to the use of evidence-based treatment principles to guide stuttering treatment, namely the lack of a substantial treatment research literature that can serve as the basis for meta-analyses and systematic reviews of effective treatment studies, are bemoaned. Guidelines are provided to aid clinicians in their own conduct of critical evaluations of treatment research. EDUCATIONAL OBJECTIVES: The reader will learn about and be able to (1) describe the four steps that characterize evidence-based practice, (2) evaluate previous efforts to develop practice guidelines for stuttering, (3) assess the importance of an evidence-based approach to stuttering treatment, and (4) discuss the need for more research that will contribute to the evidence base. 相似文献

Many differences in brain activity have been reported between persons who stutter (PWS) and typically fluent controls during oral reading tasks. An earlier meta-analysis of imaging studies identified stutter-related regions, but recent studies report less agreement with those regions. A PET study on adult dextral PWS (n = 18) and matched fluent controls (CONT, n = 12) is reported that used both oral reading and monologue tasks. After correcting for speech rate differences between the groups the task-activation differences were surprisingly small. For both analyses only some regions previously considered stutter-related were more activated in the PWS group than in the CONT group, and these were also activated during eyes-closed rest (ECR). In the PWS group, stuttering frequency was correlated with cortico-striatal-thalamic circuit activity in both speaking tasks. The neuroimaging findings for the PWS group, relative to the CONT group, appear consistent with neuroanatomic abnormalities being increasingly reported among PWS. 相似文献

We investigate laypeople's beliefs about the causes of and solutions to out‐group dehumanization and prejudice. Specifically, we examine whether nonexperts recognize the role that beliefs in the human–animal divide play in the formation and reduction of intergroup biases, as observed empirically in the interspecies model of prejudice. Interestingly, despite evidence in the present study that human–animal divide beliefs predict greater dehumanization and prejudice, participants strongly rejected the human–animal divide as a probable cause of (or solution to) dehumanization or prejudice. We conclude with a meta‐analytic test of the relation between human–animal divide and prejudice (mean r = .34) in the literature, establishing the human–animal divide as an important but largely unrecognized prejudice precursor. Applied implications for the development and implementation of prejudice interventions are considered. 相似文献

The 2 studies reported here use observational data from message boards to investigate how adolescents solicit and share information related to self-injurious behavior. Study 1 examines the prevalence and nature of these message boards, their users, and most commonly discussed topics. Study 2 was intended to explore the correlations between content areas raised for discussion. Both studies were intended to shed light on the role of message boards in spreading information about self-injurious practices and influencing help-seeking behavior. More than 400 self-injury message boards were identified. Most are populated by females who describe themselves as between 12 and 20 years of age. Findings show that online interactions clearly provide essential social support for otherwise isolated adolescents, but they may also normalize and encourage self-injurious behavior and add potentially lethal behaviors to the repertoire of established adolescent self-injurers and those exploring identity options. 相似文献

Permutation procedures to compute exact and resampling probability values associated with measures of association for ordered r x c contingency tables are described. Comparisons with asymptotic probability values demonstrated that exact and resampling permutation procedures were preferred for sparse contingency tables. 相似文献

Goodman and Kruskal's tau measure of categorical association is advanced as a replacement for conventional measures of effect size for r x c contingency tables. Goodman and Kruskal's tau is an asymmetric measure of categorical association which is based entirely on the observed data and possesses a clear interpretation in terms of proportional reduction in error. Comparisons with conventional measures of effect size based on chi-squared such as Pearson's phi2, Tschuprow's T2, and Cramer's V2 demonstrate the advantages of employing tau as a measure of effect size. 相似文献
