Basketball experts, non-experts, and novices were studied for differences in their self-regulatory forethought and self-reflection processes regarding their free-throw shooting. Forty-three adolescent boys participated individually in the study, which involved a practice session in a gymnasium. The subjects were queried regarding their forethought goals, strategy choice, self-efficacy as well as their self-reflection attributions and feelings of satisfaction as they practiced their shooting. Among the significant results, experts set more specific goals, selected more technique-oriented strategies, made more strategy attributions, and displayed higher levels of self-efficacy than non-experts and novices. Forethought phase processes intercorrelated significantly as did self-reflection phase processes. In addition, self-reflection attributions were predictive of forethought strategy selection during further efforts to learn. The results were discussed in terms of a social cognitive model of self-regulation.  相似文献

Resiliency theory posits that some youth exposed to risk factors do not develop negative behaviors due to the influence of promotive factors. This study examines the effects of cumulative risk and promotive factors on adolescent violent behavior and tests two models of resilience—the compensatory model and the protective model—in a sample of adolescent patients (14–18 years old; n = 726) presenting to an urban emergency department who report violent behavior. Cumulative measures of risk and promotive factors consist of individual characteristics and peer, family, and community influences. Hierarchical multiple regression was used to test the two models of resilience (using cumulative measures of risk and promotive factors) for violent behavior within a sample of youth reporting violent behavior. Higher cumulative risk was associated with higher levels of violent behavior. Higher levels of promotive factors were associated with lower levels of violent behavior and moderated the association between risk and violent behaviors. Our results support the risk-protective model of resiliency and suggest that promotive factors can help reduce the burden of cumulative risk for youth violence.  相似文献

Research on the formation of sanction risk perceptions has concentrated virtually exclusively on the bases of legal sanction perceptions. This article examines the correlates of extralegal risk perceptions. Theoretical arguments relate previous offending experiences to current perceptions of self-imposed (guilt) and socially imposed (social disapproval) sanctions. The empirical implications of these arguments are tested. Findings indicate that individuals' perceptions of the risk of social disapproval are associated with their own offending experiences, and individuals' perceptions of the risk of guilt are associated with their friends', as well as their own offending experiences. The findings suggest that research on the formation and modification of sanction risk perceptions should not be limited to perceptions of legal sanctions.  相似文献

For various nonnormal distributions, the power of the Student t test can be increased if continuous measures are transformed to ranks before the test is performed. The power of the test can also be increased almost as much and, even more for some distributions, if measures are replaced by dichotomous variables with the values 0 and 1, instead of ranks. Similarly, the power of a significance test of correlation can be increased if scores are transformed to ranks, that is, with the use of the Spearman rank correlation method. Power can also be increased almost as much and in some cases even more if dichotomous variables are introduced, that is, if the phi coefficient is used as a measure of correlation.  相似文献

Transgender, gender variant, and/or gender nonconforming persons are marginalized and pathologized in society and communities. The advent and widespread use of social media introduce an entirely new avenue of expression where cyber bullying and verbal assaults are common. Yet, social media also has the capacity to reach more people in more places, thus presenting a potentially powerful platform for advocacy. Grounded in digital critical participatory action research, the authors present a multimedia advocacy project that highlights advocacy strategies in which counselors can utilize social media to raise awareness, promote inclusion, and resolve microaggressions toward transgender persons.  相似文献

From the perspective of signal detection theory, different lineup instructions may induce different levels of response bias. If so, then collecting correct and false identification rates across different instructional conditions will trace out the receiver operating characteristic (ROC)—the same ROC that, theoretically, could also be traced out from a single instruction condition in which each eyewitness decision is accompanied by a confidence rating. We tested whether the two approaches do in fact yield the same ROC. Participants were assigned to a confidence rating condition or to an instructional biasing condition (liberal, neutral, unbiased, or conservative). After watching a video of a mock crime, participants were presented with instructions followed by a six‐person simultaneous photo lineup. The ROCs from both methods were similar, but they were not exactly the same. These findings have potentially important policy implications for how the legal system should go about controlling eyewitness response bias.Copyright © 2017 John Wiley & Sons, Ltd.  相似文献

Paraprofessionals need adequate training and supports to assist young children with autism spectrum disorders to engage in appropriate social interactions during small group activities with their peers. In this study, we used in situ coaching and brief post-session feedback to improve the use of environmental arrangement, prompting, and praise by three paraprofessionals working in inclusive classrooms. Results suggested the brief coaching intervention was effective for improving target behaviors. In addition, generalized use of behaviors and child outcomes were positive. In situ feedback is a promising practice for improving use of evidence-based practices by non-certified personnel in early childhood settings.  相似文献

This study investigated the multigenerational impact of mothers’ own exposure to physical maltreatment on internalizing symptoms in her child after accounting for her parenting practices, depression, and the child’s own exposure to stressful life events. Children (n?=?101, ages 5–16), predominantly African American, were recruited into this cross sectional study using ethnographic mapping and targeted sampling for high-risk neighborhoods. Mothers reported retrospectively on their own exposure to physical maltreatment in childhood, their parenting practices, as well as current depressive symptoms. Maternal report of her child’s exposure to stressful life events and child behavior was also collected. Maternal childhood exposure to physical maltreatment was significantly associated with her child’s internalizing symptoms (p?=?.004); this effect remained after accounting for child sex, maternal depressive symptoms, harsh parenting practices, and the child’s own exposure to stressful life events. Formal tests of mediation through these pathways were non-significant. Findings suggest mothers’ experience of childhood maltreatment contributes uniquely to children’s internalizing symptoms, potentially through previously uncharacterized pathways. Examination of additional behavioral, psychosocial and biological pathways may help better describe the multi-generational effects of child maltreatment.  相似文献

The Type I error probability and the power of the independent samples t test, performed directly on the ranks of scores in combined samples in place of the original scores, are known to be the same as those of the non‐parametric Wilcoxon–Mann–Whitney (WMW) test. In the present study, simulations revealed that these probabilities remain essentially unchanged when the number of ranks is reduced by assigning the same rank to multiple ordered scores. For example, if 200 ranks are reduced to as few as 20, or 10, or 5 ranks by replacing sequences of consecutive ranks by a single number, the Type I error probability and power stay about the same. Significance tests performed on these modular ranks consistently reproduce familiar findings about the comparative power of the t test and the WMW tests for normal and various non‐normal distributions. Similar results are obtained for modular ranks used in comparing the one‐sample t test and the Wilcoxon signed ranks test.  相似文献
