Despite a general perception that violent or scary television creates anxiety in children, the research literature is small and disparate. A meta‐analysis quantifies the impact of scary television and film on children's internalizing emotions (fear, anxiety, sadness, and sleep problems). Scary television has a relatively small impact on children's internalizing emotions (r = .18) overall, and this association was not significantly moderated by whether the televised material was factual (e.g., news) or fictional or contained violence. Children under 10 were more susceptible to scary TV. The overall result contrasts with the dramatic effects found for individual children within studies, suggesting that research is needed to unpick the factors that moderate the effect that scary television has on children. 相似文献

Priming students for whole-class interaction: using interdependence to support behavioral engagement
Student interaction at a whole-class level is tied to learning outcomes, but encouraging students to engage with their peers at a whole-class level is difficult. While little research has sought to promote student engagement with one another at this level, one factor that has been shown to increase student interaction in pairs and small groups is student–student interdependency. Yet, to date, no studies have attempted to examine the impact of prior interdependency at this smaller scale on students’ interactions as a whole-class. The current study tested this relationship in an undergraduate class learning science content (n?=?19) through structuring interdependency (task and resource) during science learning. Students completed six science learning sessions each of which included a science learning activity followed by a whole-class concept mapping task. Students were audio and video recorded during the whole-class task, and then individual student behavior was coded in 10 s intervals during the first 10 min of each session. Generalized regression results showed that adding small group interdependency during learning predicted significantly more student science discussion (R2?=?.05) and supportive interactions (R2?=?.16), while predicting decreased expressions of science misunderstanding (R2?=?.07) during the whole-class task. Additionally, the combination of task and resource interdependency predicted a further decrease in student expressions of misunderstanding (R2?=?.07), but also increased student social distraction in comparison to task interdependency alone (R2?=?.28). Together these findings suggest that prior interdependency can be leveraged to increase student behavioral engagement at the whole-class level. 相似文献

Recent interest has emerged in understanding the neural mechanisms by which deficits in emotion regulation (ER) early in development may relate to later depression. Corticolimbic alterations reported in emotion dysregulation and depression may be one possible link. We examined the relationships between emotion dysregulation in school age, corticolimbic resting-state functional connectivity (rs-FC) in preadolescence, and depressive symptoms in adolescence. Participants were 143 children from a longitudinal preschool onset depression study who completed the Children Sadness Management Scale (CSMS; measuring ER), Child Depression Inventory (CDI-C; measuring depressive symptoms), and two resting-state MRI scans. Rs-FC between four primary regions of interest (ROIs; bilateral dorsolateral prefrontal cortex [dlPFC] and amygdala) and six target ROIs thought to contribute to ER were examined. Findings showed that ER in school age did not predict depressive symptoms in adolescence, but did predict preadolescent increases in dlPFC-insula and dlPFC-ventromedial PFC rs-FC across diagnosis, as well as increased dlPFC-dorsal anterior cingulate cortex (dACC) rs-FC in children with a history of depression. Of these profiles, only dlPFC-dACC rs-FC in preadolescence predicted depressive symptoms in adolescence. However, dlPFC-dACC connectivity did not mediate the relationship between ER in school age and depressive symptoms in adolescence. Despite the absence of a direct relationship between ER and depressive symptoms and no significant rs-FC mediation, the rs-FC profiles predicted by ER are consistent with the hypothesis that emotion dysregulation is associated with abnormalities in top-down control functions. The extent to which these relationships might confer greater risk for later depression, however, remains unclear. 相似文献

Demonstrations of retrospective revaluation suggest that remembered stimuli undergo a reduction in association with the unconditioned stimulus (US) present during learning. Conversely, demonstrations of mediated conditioning in flavor-conditioning experiments with rats suggest that remembered stimuli undergo an increase in association with the US present during learning. In a food allergy prediction task with 23 undergraduates, we demonstrated simultaneous backward conditioned inhibition and mediated conditioning effects. These results are compatible with the hypothesis that the direction of change (decrease or increase) in associative strength depends on whether the remembered stimulus was of a different category (conditioned stimulus/antecedent) or the same category (US/outcome) as the presented US. 相似文献

Vaesen disregards a plausible alternative to his position, and so fails to offer a compelling argument for unique cognitive mechanisms. We suggest an ecological alternative, according to which divergent relationships between organism and environment, not exotic neuroanatomy, are responsible for unique cognitive capacities. This approach is pertinent to claims about primate cognition; and on this basis, we argue that Vaesen's inference from unique skills to unique mechanisms is unwarranted. 相似文献

This study examined full-time faculty in Christian, faith-based colleges and universities and investigated the type of impact their participation in the decision-making process had on job satisfaction. Previous studies have examined relationships among faculty at state universities and community colleges, yet little research has been examined in the area of full-time faculty at faith-based universities. This study sampled 145 full-time faculties at faith-based universities and examined the demographic variables of gender, age, years of teaching experience, degree, rank and salary groups, and participation. Regression analysis indicated that there were no significant relationships, while t-tests and analysis of variance (ANOVA) revealed no significant differences. Discussion of the findings focused on possible reasons these findings differ from those in studies investigating public colleges and universities. 相似文献

Abstract Theoretical and empirical developments with the locus of control construct demonstrate that it is a context-specific multidimensional construct that has implications for stress and well-being. In this paper, the multidimensionality of work-specific locus of control is explored by subjecting Spector's work locus of control scale to principal components analysis. Using samples of 221 university staff and 399 accountants, a two-dimensional structure was uncovered; external agents control and personal control. Correlations with constructs that have been theoretically and empirically associated with locus of control indicate slightly divergent results for the two dimensions, thus demonstrating the importance of treating locus of control as a domain-specific multidimensional construct. In addition, test-retest data with a subsample of 246 accountants suggested that work locus of control may be thought of as a state rather than trait measure. 相似文献
