This study examines the impact of the “Great Recession” (from December 2007 to June 2009) on 8th and 10th graders in the USA, using annual nationally representative data from the Monitoring the Future study. Historical changes in youth adjustment (self‐esteem, depressed mood, risk taking, aggression and property crime), school achievement (grade point average [GPA], time spent on homework and educational expectations) and structured and unstructured activities (volunteering, employment, sports and evenings out for fun) were examined between 1991 and 2014. Overall, there were only slight changes in mean levels of adjustment, achievement and most youth activities. However, the percentage of youth working during the school year did decline during the Great Recession. Several longer‐term trends were also evident, though not directly tied to the Great Recession. These include an increase in GPA, a decrease in time spent on homework, rising educational expectations and more time spent volunteering. Future work should assess how the shift to unpaid work activities (e.g. volunteering and internships) among youth is impacting the transition from school to work in the contemporary economy, and whether the Great Recession had deleterious impacts for younger children or among youth whose parents lost work or had their homes foreclosed.  相似文献

In a sample of detained male adolescents (n = 107; Mean age = 15.50; SD = 1.30), we tested whether anxiety moderated the association of CU traits with self-report and computerized measures of affective (emotional reactivity) and cognitive (affective facial recognition and Theory of Mind [ToM]) empathy. Hierarchical regression analyses revealed that CU traits were negatively associated with self-reports of affective empathy and this association was not moderated by level of anxiety. Significant interactions revealed that CU traits were negatively associated with cognitive empathy (self-report) only at high levels of anxiety, whereas CU traits were positively associated with cognitive empathy on the ToM task only at low levels of anxiety. CU traits were also associated with greater fear recognition accuracy at low levels of anxiety. Implications for understanding and treating different variants of CU traits (i.e., primary and secondary) are discussed.  相似文献

The aim of this article is to illustrate how a discourse‐oriented approach would open new theoretical and methodological perspectives to the study of community identity. Here outlined is the idea that community identity is discursively constructed by members in order to lend meaning to experience. An analysis of how community identity is constructed in subjects' discourse with reference to the local context is presented. Copyright © 2004 John Wiley & Sons, Ltd.  相似文献

Autism spectrum disorder (ASD) and typically developed (TD) adult participants viewed pairs of scenes for a simple "spot the difference" (STD) and a complex "which one's weird" (WOW) task. There were no group differences in the STD task. In the WOW task, the ASD group took longer to respond manually and to begin fixating the target "weird" region. Additionally, as indexed by the first-fixation duration into the target region, the ASD group failed to "pick up" immediately on what was "weird". The findings are discussed with reference to the complex information processing theory of ASD (Minshew & Goldstein, 1998 ).  相似文献

Through his development of Rational Emotive Behaviour Therapy (REBT), Albert Ellis was a major contributor to the development of cognitive behaviour therapy. This article reviews key aspects of REBT, the distinction between unhealthy and healthy emotions, and the role irrational and rational beliefs play in relation to these emotions. As with other areas of psychology, the focus of REBT over the years has been dominated by negative emotional experiences. In an attempt to address this and further develop REBT, the present article reviews recent claims from the realm of social psychology that positive illusions promote mental health. Consequently, it is proposed that a similar dichotomy of healthy and unhealthy positive emotions also exists, and a basic framework for working with this positive dichotomy is introduced.  相似文献

A major ethical concern in research with criminal offenders is the potential for abuse due to coercive influences that may adversely affect offenders' capacity to give voluntary consent to participate in research conducted in correctional settings. Despite this concern, to date there have been almost no systematic scientific investigations of the extent to which offenders themselves perceive that coercion occurs in these settings or that it is likely to influence their decisions about research participation. In a sample of over 600 ethnically diverse men and women recruited from various prisons and community corrections facilities in Texas and Florida, we used a vignette-based survey concerning a hypothetical research project to measure and compare offenders' global perceptions of coercive processes, as well as the differential salience and perceived coercive influence of specific factors (e.g., coercion by other inmates, inducements from staff). Somewhat surprisingly, across multiple outcome measures our participants on average reported relatively little in the way of significant coercive influences on their capacity to make voluntary decisions concerning research participation. Implications and directions for future research on coercive influences in offender research are discussed.  相似文献

This study examined the structure of a self-report measure of the forms and functions of aggression in 855 adolescents (582 boys, 266 girls) aged 12 to 19 years recruited from high school, detained, and residential settings. The Peer Conflict Scale (PCS) is a 40-item measure that was developed to improve upon existing measures and provide an efficient, reliable, and valid assessment of four dimensions of aggression (i.e., reactive overt, reactive relational, proactive overt, and proactive relational) in youths. Confirmatory factor analyses showed that a 4-factor model represented a satisfactory solution for the data. The factor structure fit well for both boys and girls and across high school, detained, and residential samples. Internal consistency estimates were good for the 4 factors, and they showed expected associations with externalizing variables (i.e., arrest history, callous-unemotional traits, and delinquency). Reactive and proactive subtypes showed unique associations consistent with previous literature. Implications for the use of the PCS to assess aggression and inform intervention decisions in diverse samples of youths are discussed.  相似文献

Although the use of semantic information about the world seems ubiquitous in every task we perform, it is not clear whether we rely on a scene’s semantic information to guide attention when searching for something in a specific scene context (e.g., keys in one’s living room). To address this question, we compared contribution of a scene’s semantic information (i.e., scene gist) versus learned spatial associations between objects and context. Using the flash-preview–moving-window paradigm Castelhano and Henderson (Journal of Experimental Psychology: Human Perception and Performance 33:753–763, 2007), participants searched for target objects that were placed in either consistent or inconsistent locations and were semantically consistent or inconsistent with the scene gist. The results showed that learned spatial associations were used to guide search even in inconsistent contexts, providing evidence that scene context can affect search performance without consistent scene gist information. We discuss the results in terms of hierarchical organization of top-down influences of scene context.  相似文献

This exploratory cross-sectional study examined fluid cognitive skills and standardized verbal IQ scores in relation to cultural engagement amongst Tohono O'odham children (N = 99; ages 7 to 12 years). Guardians with higher socioeconomic status engaged their children in more cultural activities, and participation in more cultural activities contributed to higher standardized verbal IQ scores. Mean cognitive skill scores varied as a function of age and Tohono O'odham language knowledge. Children who understood and/or spoke Tohono O'odham started out with lower average scores than did children with no language knowledge, but mean scores generally increased in the older age groups such that they were equal to or higher than those of nonspeakers by age 9. Children with higher fluid cognitive skill scores had higher standardized verbal IQ scores than did children with lower scores.  相似文献
