Age‐related differences in sensory functioning, processing speed, and working memory have been identified as three significant predictors of the age‐related performance decline observed in complex cognitive tasks. Yet, the assessment of their relative predictive capacity and interrelations is still an open issue in decision making and cognitive aging research. Indeed, no previous investigation has examined the relationships of all these three predictors with decision making. In an individual‐differences study, we therefore disentangled the relative contribution of sensory functioning, processing speed, and working memory to the prediction of the age‐related decline in cognitively demanding judgment and decision‐making tasks. Structural equation modeling showed that the age‐related decline in working memory plays an important predictive role, even when controlling for sensory functioning, processing speed, and education. Implications for research on decision making and cognitive aging are discussed. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

Aboriginal children in Canada are at high risk of fetal alcohol spectrum disorder (FASD) but there is little research on the cognitive impact of prenatal alcohol exposure (PAE) in this population. This paper reviews the literature on parent report of executive functioning in children with FASD that used the Behavior Rating Inventory of Executive Function (BRIEF). New data on the BRIEF is then reported in a sample of 52 Aboriginal Canadian children with FASD for whom a primary caregiver completed the BRIEF. The children also completed a battery of neuropsychological tests. The results reveal mean scores in the impaired range for all three BRIEF index scores and seven of the eight scales, with the greatest difficulties found on the Working Memory, Inhibit and Shift scales. The majority of the children were reported as impaired on the index scores and scales, with Working Memory being most commonly impaired scale. On the performance-based tests, Trails B and Letter Fluency are most often reported as impaired, though the prevalence of impairment is greater for parent ratings than test performance. No gender difference is noted for the parent report, but the boys had slightly slower intellectual functioning and were more perseverative than the girls on testing. The presence of psychiatric comorbidity is unrelated to either BRIEF or test scores. These findings are generally consistent with prior studies indicating that parents observe considerable executive dysfunction in children with FASD, and that children with FASD may have more difficulty with executive functions in everyday life than is detected by laboratory-based tests alone. 相似文献

There is considerable evidence for an association between obesity and impaired executive function (EF) in adolescents and adults. However, little research has examined EF in overweight or obese children. Furthermore, data on EF in underweight individuals is lacking. In addition, there is no consensus on the directionality of the relationship between Body Mass Index (BMI) and EF, and longitudinal studies are rare. Thus, the present study examined whether children differ in their performance on a battery of EF tasks depending on their weight status (underweight, normal-weight, overweight), and investigated the longitudinal cross-lagged associations between EF and BMI. Hot EF (delay of gratification, affective decision-making), cool EF (attention shifting, inhibition, working memory [WM] updating), and BMI were assessed in 1,657 German elementary-school children at two time points, approximately one year apart. Overweight children exhibited slightly poorer attention shifting, WM updating, and affective decision-making abilities as compared to normal-weight children. Unexpectedly, they did not show any deficits in inhibition or delay of gratification. EF levels of underweight children did not differ significantly from those of normal-weight children. Furthermore, poor attention shifting and enhanced affective decision-making predicted a slightly higher BMI one year later, and a higher BMI also predicted poorer attention shifting and WM updating one year later. The latter association between BMI and subsequent EF scores, however, diminished when controlling for socioeconomic status. Results indicate that hot and cool EF plays a role in the weight development of children, and might be a promising factor to address in preventive interventions. 相似文献

This study aimed to evaluate the degree to which the Behavior Rating Inventory of Executive Function (BRIEF) and Child Behavior Checklist (CBCL) measure overlapping vs. distinct constructs in pediatric patients with mild traumatic brain injury (TBI), and to examine the demographic and injury correlates of such constructs as well as those of cognitive test performance. A total of 100 parents completed the BRIEF and the CBCL within 1 to 12 months after the injury of their child. Groups were contrasted based on the presence vs. absence of impairment on, respectively, the BRIEF and the CBCL. Exploratory maximum likelihood factor analysis was used to evaluate latent constructs. Correlates of the various factor scores were evaluated through regression analysis and contrasted with those of a test of verbal learning and memory.The results revealed that the BRIEF and the CBCL disagree about the presence vs. absence of impairment in about one quarter of cases. A prior history of attention deficit/hyperactivity disorder (ADHD) was associated with an increased likelihood of impairment on both the BRIEF and the CBCL, whereas prior outpatient psychiatric treatment was associated with the increased likelihood of selective impairment on the CBCL. Latent constructs manifested themselves along cognitive regulation, emotional adjustment and behavioral regulation factors. Whereas premorbid characteristics were the exclusive correlates of these factors, performance on a test of verbal learning and memory was negatively affected by intracranial lesions on neuroimaging.It is concluded that the BRIEF and the CBCL offer complementary and non-redundant information about daily functioning after pediatric mild TBI. The correlates of cognitive test performance and parental behavior ratings after such injuries are different and reflect a divergence between premorbid and injury-related influences. 相似文献

应用项目反应理论对《中国士兵人格问卷》的项目分析 总被引:4,自引:0,他引:4
采用项目反应理论(IRT)对《中国士兵人格问卷》进行项目分析。计算机呈现中国士兵人格问卷(CSPQ)对100,523名适龄男性青年进行测验,随机抽取2676名任一维度标准分均低于70的定为合格组;将任一维度大于70分并经专业人员访谈不合格的274名定为不合格组;从精神病院抽取男性年龄相当的221名缓解期精神分裂症患者定为精神病组,并完成CSPQ测验。运用基于IRT的双参数Logistic模型进行分析;结果发现,区分度参数超过区间(0.30,4.00)的条目删除前后,被试的能力值与标准分均存在显著相关;精神病组的测验分数经IRT分析,图形曲线与不合格组有高度吻合。研究结果说明,在测验精度基本相同的条件下,应用IRT可以减少施测条目,提高测验效率,可在一定程度上更精确地区分被试的特质水平 相似文献

Rüdiger Bittner argues that regret is not useful and so it is always unreasonable to feel and express it. In this paper, I argue that regret is often reasonable because regret has a communicative function: it communicates where we stand with respect to things we have done and outcomes that we have caused. So, I not only argue that Bittner’s argument is unsuccessful, I also shed light on the nature and purpose of regret. 相似文献

This study utilized performance-based and self-report measures to examine differences in executive functions in college students with and without histories of childhood maltreatment. On the performance-based measures of executive function, all scores fell within the normal range for age. However, participants in the childhood maltreatment group reported more problems with metacognition than those without history of maltreatment. Severity of childhood maltreatment was associated with poorer cognitive inhibition/switching and phonetic fluency. Although significant group differences were found on a laboratory-based task of executive function, performance across the other tasks was generally similar. However, those with a history of maltreatment reported more problems with metacognition, suggesting a potential avenue for brief interventions focused on improving metacognitive skills important for success in the college environment. Implications and suggestions for future research are discussed. 相似文献
