Risk behavior during adolescence results in substantial morbidity and mortality. Sensation seeking consistently relates to engagement in risk behavior, but the psychological mediators of this relationship remain unclear. The current study demonstrates that adolescents’ judgments of the costs versus benefits of risk behavior were a significant mediator of this relationship. Participants were 406 racially and ethnically diverse adolescents ages 12-17 (M = 14.5, SD = 1.7; 48.3% female) who participated in a larger multi-site investigation of personality and neurocognitive predictors of risk behavior. Data were collected via self-report in a single laboratory session. Mediation of the relationship of sensation seeking to risk behavior was tested using structural equation modeling. Results indicated that higher levels of sensation seeking predicted weighing the benefits of risk behavior higher than its costs, which in turn predicted higher levels of risk behavior. Implications of these findings for understanding mechanisms underlying adolescents’ risk behavior and directions for future research are discussed.  相似文献

The experiments conducted aimed to investigate whether reduced accuracy when counting stimuli presented in rapid temporal sequence in adults with dyslexia could be explained by a sensory processing deficit, a general slowing in processing speed or difficulties shifting attention between stimuli. To achieve these aims, the influence of the inter-stimulus interval (ISI), stimulus duration, and sequence length were evaluated in two experiments. In the first that used skilled readers only, significantly more errors were found with presentation of long sequences when the ISI or stimulus durations were short. Experiment 2 used a wider range of ISIs and stimulus durations. Compared to skilled readers, a group with dyslexia had reduced accuracy on two-stimulus sequences when the ISI was short, but not when the ISI was long. Although reduced accuracy was found on all short and long sequences by the group with dyslexia, when performance on two-stimulus sequences was used as an index of sensory processing efficiency and controlled, group differences were found with presentation of stimuli of short duration only. We concluded that continuous, repetitive stimulation to the same visual area can produce a capacity limitation on rapid counting tasks in all readers when the ISIs or stimulus durations are short. While reduced accuracy on rapid sequential counting tasks can be explained by a sensory processing deficit when the stimulus duration is long, slower processing speed in the group with dyslexia explains the greater inaccuracy found as sequence length is increased when the stimulus duration is short.  相似文献

Successful communication requires that individuals attend to the perspective of their conversational partners and use this information to modify their behavior accordingly. This paper presents a framework by which to understand children’s communicative perspective-taking skills and, within this framework, outlines three routes by which children’s communicative perspective-taking performance can be disrupted. First, children may have difficulty in communicative contexts due to deficits in mentalizing ability whereby they are unable to appreciate another’s perspective. Second, children may have intact mentalizing abilities but do not have the cognitive skills to support the use of this information when generating communicative behaviors. Third, decreased social exposure may lead to exacerbated deficits in either mentalizing ability or the use of mentalistic information within communicative contexts. Patterns within both typical and atypical populations (i.e., autism, ADHD, and mood disorders) are reviewed.  相似文献

Elder mistreatment is now recognized as a worldwide social problem occurring in all racial and ethnic groups. The research on elder mistreatment started in the late 1970s and expanded its focus to ethnic elderly groups including Asian elders in the mid-1980s. Many researchers have explored the issues of elder mistreatment in conjunction with Asian elders’ culture and immigration backgrounds. This article reviews the state of the literature on elder mistreatment among Asians living in Asia or abroad to identify future directions of research, prevention, intervention, and policy. This research indicates that prevention, education, and intervention must take into account the cultural backgrounds of Asian elders and their family members. There is clearly a need for greater research into appropriate elder mistreatment prevention and intervention with Asian elders and their family members.  相似文献

Judgment is widely recognized as an important executive function, and deficits in judgment can lead to health risks, safety concerns, and hospitalizations. Surprisingly, relatively few tests of judgment have been developed specifically for older adults—a population particularly vulnerable to executive and functional declines. The Kitchen Picture Test (KPT) is a new screening measure of practical judgment. In two independent studies (Study 1, N = 99 nursing home patients; Study 2, N = 163 nursing home and assisted living patients), psychometric analyses confirmed strong evidence for reliability, construct validity, and predictive validity. A receiver operating characteristic (ROC) curve was calculated from sensitivity and 1-specificity values for diagnoses of dementia versus no dementia. A KPT cut score can be used for identifying persons to be referred to appropriate health-care professionals who have specific expertise in the evaluation and treatment of cognitive impairment.  相似文献

The structure and development of executive functioning (EF) have been intensively studied in typically developing populations, with little attention given to those with Special Educational Needs (SEN). This study addresses this by comparing the EF structure of 132 adolescents (11–14 years-old) with SEN and 138 adolescents not requiring additional support (Non-SEN peers). Participants completed verbal and non-verbal assessments of key components of EF: inhibition, working memory and switching. Confirmatory Factor Analysis on each group tested one-, two- and three-factor models of EF. In both groups, there was statistical support for the fit of one- and two-factor models with no model being clearly better than the others; there was little support for three-factor models. Parsimony suggests that the one-factor model best represents the structure of EF. In light of our results, the implications for the nature of EF in early adolescence in both SEN and Non-SEN groups are discussed.  相似文献

Youth who experience aggression at the hands of peers are at an increased risk for a variety of adjustment difficulties, including depressive and anxiety symptoms and lower self-esteem. The links between peer victimization and internalizing problems are robust, but less work has been done to identify individual-level protective factors that might mitigate these outcomes. The current study investigated whether hope served as a moderator of the prospective links from peer victimization to depressive and anxiety symptoms and self-esteem during adolescence. Participants included 166 high school students (64% female; 88% Black/African American). Youth completed self-report measures at three different time points across the Spring semester of an academic year. As predicted, hope interacted with peer victimization to predict changes in depressive and anxiety symptoms over the course of the semester. That is, for youth with low levels of hope, peer victimization predicted more stable patterns of depressive and anxiety symptoms. For adolescents with average levels of hope, however, peer victimization did not influence anxiety and depressive symptoms over time. Finally, for adolescents with high levels of hope, peer victimization predicted greater decreases in anxiety symptoms over time. Hope did not interact with peer victimization to predict self-esteem. Rather, hope uniquely predicted higher levels of self-esteem, whereas peer victimization uniquely predicted lower levels of self-esteem. The current study provides initial support for the notion that hope can serve as a protective factor among youth who are victims of peer aggression.
