The generation effect involves an improvement in memory when learners must complete or modify materials. Several researchers have suggested that this effect involves enhanced access to learners' existing memory representations; therefore, the effect should be less effective with meaningless, low meaningful, or unfamiliar material. In the present study, the authors conducted 4 experiments in which legal nonwords were used, and they found no generation effect. In another 2 experiments in which familiar clichés were contrasted with new sentences and with unfamiliar sentences from textbooks, the results showed a greatly reduced generation effect for the new, unfamiliar material. Those findings suggest that memory strategies that depend on the generation effect will have limited effectiveness when they are applied to new or unfamiliar material.  相似文献

This research examined the hypothesis that gender gaps in voting stem from differences in the extent to which men and women agree with candidates' issue stances. Two initial experiments portraying candidates by their sex and attitudes and a third experiment that also included information about political party produced the predicted attitudinal gender-congeniality effect: Participants of each sex reported greater likelihood, compared with participants of the other sex, of voting for the candidate who endorsed positions typically favored more by their own sex than the other sex. In addition, this gender-congeniality effect was present among Republican and independent participants but absent among Democratic participants because Democratic men as well as women favored candidates who advocated the positions typically favored by women. Interpretation invoked the importance of group interest based on gender as an influence on women's voting.  相似文献

The current study sought to provide a better understanding of the reactions of bone-marrow volunteers to the possibility of donating by examining these volunteers in the context of their closest relationships. Using Tesser's (1988) self-evaluation maintenance (SEM) model as a guide, we examined the influence of spouses who are also volunteers on each member of the couple's distress levels and on the marrow volunteer's ambivalence about donating. We also examined the independent effects of known risk factors for donation-related distress and the combined effects of spouse volunteer status and these risk factors on distress levels. Questionnaire data were collected from 278 couples selected from 39 bone-marrow donor centers. Results demonstrated that when spouses of potential donors were engaged in any type of volunteer activity, members of the couple felt greater anxiety than when spouses were not volunteers. Additionally, other variables were found to have a conjoint effect with spouse volunteer status on volunteer and spouse anxiety levels.  相似文献

Parenting and family interventions have repeatedly shown effectiveness in preventing and treating a range of youth outcomes. Accordingly, investigators in this area have conducted a number of studies using statistical mediation to examine some of the potential mechanisms of action by which these interventions work. This review examined from a methodological perspective in what ways and how well the family-based intervention studies tested statistical mediation. A systematic search identified 73 published outcome studies that tested mediation for family-based interventions across a wide range of child and adolescent outcomes (i.e., externalizing, internalizing, and substance-abuse problems; high-risk sexual activity; and academic achievement), for putative mediators pertaining to positive and negative parenting, family functioning, youth beliefs and coping skills, and peer relationships. Taken as a whole, the studies used designs that adequately addressed temporal precedence. The majority of studies used the product of coefficients approach to mediation, which is preferred, and less limiting than the causal steps approach. Statistical significance testing did not always make use of the most recently developed approaches, which would better accommodate small sample sizes and more complex functions. Specific recommendations are offered for future mediation studies in this area with respect to full longitudinal design, mediation approach, significance testing method, documentation and reporting of statistics, testing of multiple mediators, and control for Type I error.  相似文献

In several previous studies, 18‐month‐old infants who were directly addressed demonstrated more robust imitative behaviors than infants who simply observed another's actions, leading theorists to suggest that child‐directed interactions carried unique informational value. However, these data came exclusively from cultural communities where direct teaching is commonplace, raising the possibility that the findings reflect regularities in infants' social experiences rather than responses to innate or a priori learning mechanisms. The current studies consider infants' imitative learning from child‐directed teaching and observed interaction in two cultural communities, a Yucatec Mayan village where infants have been described as experiencing relatively limited direct instruction (Study 1) and a US city where infants are regularly directly engaged (Study 2). Eighteen‐month‐old infants from each community participated in a within‐subjects study design where they were directly taught to use novel objects on one day and observed actors using different objects on another day. Mayan infants showed relative increases in imitative behaviors on their second visit to the lab as compared to their first visit, but there was no effect of condition. US infants showed no difference in imitative behavior in the child‐directed vs. observed conditions; however, infants who were directly addressed on their first visit showed significantly higher overall imitation rates than infants who observed on their first visit. Together, these findings call into question the idea that child‐directed teaching holds automatic or universal informational value.  相似文献

Many community mental health centers have implemented peer treatment models that employ recovered former clients as cost‐efficient adjunct providers. The effectiveness of these and other peer‐administered interventions (PAIs) for treating depression symptoms has not been well‐established. The current study is a meta‐analysis of PAIs’ effects on depression symptoms. Twenty‐three eligible studies were identified. Study characteristics were coded by multiple raters, random‐effects models were used to compare mean effect sizes, and mixed‐effects models were used to test for moderation. PAIs produced significant pre‐post reductions in depression symptoms (d = .5043 [95 % CI .3675–.6412]). In direct comparisons, PAIs performed as well as non‐peer‐administered interventions (.0848 [?.1455–.3151]), and significantly better than no‐treatment conditions (.2011 [.0104–.3918]). PAIs that involved a professional in a secondary treatment role were significantly less effective than those that were purely peer‐administered, and educational/skills‐based PAIs produced better outcomes than those that were mainly supportive. Follow‐up data, when available, indicated that PAIs’ benefits were maintained. PAIs reduce depression symptoms and warrant further study. The clinical significance of PAIs’ benefits, and whether they are better suited as stand‐alone or adjunct treatments, remain to be established. Implications for the roles of mental health professionals are discussed.  相似文献

Service use disparities have been noted to impede under‐resourced families' ability to access high‐quality services for their child with autism spectrum disorder (ASD). These disparities are particularly relevant for parent‐mediated interventions and may suggest a lack of fit between these interventions and the needs of under‐resourced community settings. This study used Roger's Diffusion of Innovations theory to guide community partnerships aimed at understanding the perceived compatibility, complexity, and relative advantage of using an evidence‐based, parent‐mediated intervention (Project ImPACT) within a Medicaid system. Three focus groups were conducted with 16 Medicaid‐eligible parents, and three focus groups were conducted with 16 ASD providers operating within a Medicaid system. Across all groups, parents and providers reported general interest in using Project ImPACT. However, primary themes emerged regarding the need to (a) reduce the complexity of written materials; (b) allow for a more flexible program delivery; (c) ensure a strong parent–therapist alliance; (d) involve the extended family; and (e) help families practice the intervention within their preexisting routines. Results are discussed as they relate to the design and fit of evidence‐based, parent‐mediated interventions for under‐resourced community settings.  相似文献

This study focused on the extent to which religion, spirituality, and political beliefs predicted counseling students' perceptions of psychological safety and appreciation of differences in their programs. The authors used hierarchical regression models to analyze data from 264 students from 4 different institutions. Results indicated that student age, political conservatism, extrinsic religiosity, and intrinsic spirituality were significant predictors of perceived psychological safety and appreciation of differences. The authors discuss implications of these findings.  相似文献

This quantitative study examined professional identity development and orientation for 489 counseling practitioners, educators, and trainees as predicted by participant‐identified sex and engagement in professional activities. Differences between male and female participants regarding aspects of professional identity were evaluated. Discriminant analysis results indicate sex differences in professional identity development. Additional regression analysis revealed a significant predictive relationship between professional engagement and professional identity orientation and development.  相似文献
