ABSTRACT

Rumination and worry are two perseverative, negatively valenced thought processes that characterise depressive and anxiety disorders. Despite significant research interest, little is known about the everyday precipitants and consequences of rumination and worry. Using an experience sampling methodology, we examined and compared rumination and worry with respect to their relations to daily events and affective experience. Participants diagnosed with Major Depressive Disorder (MDD), Generalized Anxiety Disorder (GAD), co-occurring MDD–GAD, or no diagnosis carried an electronic device for one week and reported on rumination, worry, significant events, positive affect (PA), and negative affect (NA). Across the clinical groups, occurrences of everyday events predicted subsequent increases in rumination, but not worry. Further, higher momentary levels of rumination, but not worry, predicted subsequent decreases in PA and increases in NA. Thus, in these clinical groups, rumination was more susceptible to daily events and produced stronger affective changes over time. We discuss implications for theory and clinical intervention.  相似文献

Stereotype threat—a situational context in which individuals are concerned about confirming a negative stereotype—is often shown to impact test performance, with one hypothesized mechanism being that cognitive resources are temporarily co‐opted by intrusive thoughts and worries, leading individuals to underperform despite high content knowledge and ability (see Schmader & Beilock, 2012 ). We test here whether stereotype threat may also impact initial student learning and knowledge formation when experienced prior to instruction. Predominantly African American fifth‐grade students provided either their race or the date before a videotaped, conceptually demanding mathematics lesson. Students who gave their race retained less learning over time, enjoyed the lesson less, reported a diminished desire to learn more, and were less likely to choose to engage in an optional math activity. The detrimental impact was greatest among students with high baseline cognitive resources. While stereotype threat has been well documented to harm test performance, the finding that effects extend to initial learning suggests that stereotype threat's contribution to achievement gaps may be greatly underestimated.  相似文献

Deictic linking gestures, hand and arm motions that physically embody links being communicated between two or more objects in the shared communicative environment, are explored in a cross-cultural sample of mathematics instruction. Linking gestures are specifically examined here when they occur in the context of communicative analogies designed to link two distinct yet mutually informative representations. Video coding of eighth-grade mathematics lessons in the United States, Japan, and Hong Kong revealed that teachers in the higher achieving regions (Hong Kong and Japan) used reliably more linking gestures concurrent with verbal linkages than did U.S. teachers. Further, they were significantly more likely to tailor their gesture use to the recency of students’ experiences with source than U.S. teachers. The overall data align with growing evidence that U.S. teachers may not systematically capitalize on pedagogical opportunities to draw linkages between representations and that gestures may play a key role in doing so.  相似文献

Military personnel endure rigorous and demanding man-hours designated to monitoring and locating targets in tasks such as cyber defense and Unmanned Aerial Vehicle (UAV) operators. These tasks are monotonous and repetitive, which can result in vigilance decrement. The objective of the study was to implement a form of noninvasive brain stimulation known as transcranial DC stimulation (tDCS) over the left frontal eye field (LFEF) region of the scalp to improve cognitive performance. The participants received anodal and cathodal stimulation of 2 mA for 30 min as well as placebo stimulation on 3 separate days while performing the task. The findings suggest that anodal and cathodal stimulation significantly improves detection accuracy. Also, a correlation was detected between percent of eye closure (PERCLOS) and blinking frequency in relation to stimulation condition. Our data suggest that tDCS over the LFEF would be a beneficial countermeasure to mitigate the vigilance decrement and improve visual search performance.  相似文献

Gendered occupational segregation remains prevalent across the world. Although research has examined factors contributing to the low number of women in male-typed occupations – namely science, technology, engineering, and math – little longitudinal research has examined the role of childhood experiences in both young women's and men's later gendered occupational attainment. This study addressed this gap in the literature by examining family gender socialization experiences in middle childhood – namely parents' attitudes and work and family life – as contributors to the gender typicality of occupational attainment in young adulthood. Using data collected from mothers, fathers, and children over approximately 15 years, the results revealed that the associations between childhood socialization experiences (~ 10 years old) and occupational attainment (~ 26 years old) depended on the sex of the child. For sons but not daughters, mothers' more traditional attitudes toward women's roles predicted attaining more gender-typed occupations. In addition, spending more time with fathers in childhood predicted daughters attaining less and sons acquiring more gender-typed occupations in young adulthood. Overall, evidence supports the idea that childhood socialization experiences help to shape individuals' career attainment and thus contribute to gender segregation in the labor market.  相似文献

This study tests the effectiveness of three strategies [structured free recall (SFR), source monitoring, and error management] to reduce the impact of raters' stereotypes on evaluations of female leaders. Results reveal several three‐way interactions indicating that that the strategies became more effective as raters' implicit bias decreased. Findings show that the source monitoring and SFR methods were more effective than the error management strategy. The results have implications for improving opportunities for women to advance through the leadership ranks. This study adds to the literature by comparing multiple strategies to reduce the influence of individuals' biases in evaluations of women in leadership positions and revealing the importance of considering raters' implicit gender biases in evaluations.  相似文献

Despite positing a multiplicative model of performance, 3 recent studies failed to find support for a theoretically meaningful interaction between cognitive ability and trait motivation in predicting performance. We suggest that it is important to consider that these studies used trait–motivation constructs that are general in nature, rather than context–specific. Yet, existing theory and research suggests that it may be beneficial to use trait–motivation constructs that are expressly contextual, especially when investigating a multiplicative performance model. This study, therefore, compared general versus context–specific achievement motivation as moderators of the relationship between cognitive ability and performance. The proposition that only context–specific achievement motivation should interact with cognitive ability in predicting performance was supported. Implications are discussed.  相似文献

We investigated people's perception and knowledge of planar mirror reflections. People were accurate at deciding when they could first see their reflection as they approached a mirror from the side, but only if their reflection was visible. Most people stopped too early if the mirror was covered up. People also overestimated the size of the reflection of their face on the surface of a mirror if they were shown a covered mirror. Their accuracy improved somewhat if their reflection was visible but, unlike the first task, they still made striking errors. Perceptual feedback thus improved performance at predicting the behaviour of mirror reflections in both tasks but failed to eliminate errors in the second task. The overestimation of reflection size was not face-specific as it generalised to novel stimuli (paper ellipses) and it was found with both a matching response and for verbal size estimations. The early error in the first task appears to be due to an inaccurate belief that can be overridden by perceptual feedback. The overestimation in the second task is primarily caused by a powerful size-constancy effect.  相似文献

Two hundred and eleven undergraduate men and women were assigned to different instructional set conditions and asked to rate (1) the sexual risk depicted in a set of written items describing problem situations undergraduate women might face when dating or interacting socially with men, and (2) the effectiveness of responses to these situations, described by a set of response codes. Results revealed that sexual attitudes and instructional set were the strongest predictors of both ratings. Gender did, however, predict risk ratings for stranger and authority figure situations, with women rating these situations as more risky than men. In addition, women assigned to the risk instructional set condition rated refusal responses as more effective in decreasing risk than did men in the same condition. In contrast, women assigned to the popularity instructional set condition rated the same refusal responses as less effective in increasing popularity than did men in that condition.
