This study investigated listening comprehension and working memory abilities in children with attention-deficit hyperactivity disorder (ADHD), presenting with and without language impairments (LI). A 4-group design classified a community sample (n = 77) of boys aged 9–12 into ADHD, ADHD + LI, LI, and Normal groups. Children completed tests of basic language and cognitive skills, verbal and spatial working memory, and passage-level listening comprehension. Multivariate analyses and post hoc comparisons indicated that ADHD children who did not have co-occurring LI comprehended factual information from spoken passages as well as normal children, but were poorer at comprehending inferences and monitoring comprehension of instructions. ADHD children did not differ from normal children in verbal span, but showed significantly poorer verbal working memory, spatial span, and spatial working memory. The ADHD + LI and LI groups were most impaired in listening comprehension and working memory performance, but did not differ from each other. Listening comprehension skills were significantly correlated with both verbal and spatial working memory, and parent–teacher ratings of inattention and hyperactivity/impulsivity. Findings that children with ADHD but no LI showed subtle higher-level listening comprehension deficits have implications for both current diagnostic practices and conceptualizations of ADHD.  相似文献

This study assessed the performance of the PC-PTSD in diagnosing postdeployment posttraumatic stress disorder (PTSD) in a cohort of Air Force Medical Services personnel (N = 18,530). The prevalence of PTSD in the cohort was 5.18% based on medical record data. The area under the receiver operating characteristic curve was 0.69, indicating poor classification accuracy. Sensitivity was 47.55%, specificity was 90.68%, positive predictive value was 21.79%, and negative predictive value was 96.94%. The positive and negative likelihood ratios were 5.10 and 0.58, respectively. Several risk factors were found to be associated with a diagnosis of postdeployment PTSD: being a nurse, being enlisted in the medical service career field, being enlisted in the mental health service career field, those over age 30, being a member of the Active Duty service component, and having one’s first deployment be to Iraq. Being an officer was found to be a protective characteristic. These factors could potentially improve screening for PTSD among Air Force healthcare personnel.  相似文献

School counselors play a crucial role in the prevention, assessment, treatment, and overall management of eating‐related problems among children and adolescents. This article provides a framework for conceptualizing these difficulties on a continuum of severity and includes recommendations at each level for intervention and consultation. Collaboration with other professionals is encouraged when confronted with these multifaceted issues. Efforts by school counselors are vital to prevention and recovery from eating disorders.  相似文献

Despite the prevalence of and risk associated with disordered eating, there are few guidelines for counselors on how to conduct an eating disorder assessment. Given the importance of the clinical interview, the purpose of this article is to provide recommendations for the assessment and diagnosis of eating disorders that (a) specifically focus on assessment in the context of a clinical interview and (b) can be used by counselors whether or not they specialize in eating disorder treatment.  相似文献

采用事件相关电位技术(ERP),通过简单赌博任务,操纵结果预期的效价(输或赢)与风险(高风险与低风险),考察了个体对结果预期阶段的效价和风险评估的脑内时程动态加工过程。脑电结果发现:(1)在N2成分上,结果预期的效价主效应显著,预期输比预期赢能够引起更大的N2波幅;结果预期的风险主效应不显著。(2)在N500成分上,效价与风险之间的交互作用边缘显著,进一步简单效应分析发现,在预期输的条件下,肯定会输的N500波幅显著大于可能会输;而在预期赢的条件下,肯定会赢与可能会赢之间的N500波幅差异不显著。这说明,在不确定决策过程中的结果预期阶段,个体可能先对结果预期的效价进行加工,然后再对风险进行评估。  相似文献

Children's talk about the mind has been scarcely studied in non‐English speakers. For this reason, this longitudinal study documents age‐related changes in German‐speaking children's internal state language. At 24, 30 and 36 months, children were administered general language tests and their internal state vocabulary levels were obtained via parental report. The developmental transition from a vocabulary rich in physiological, perceptual and desire terms to a vocabulary rich in a wider range of mental concepts confirmed previous research with French‐speaking and English‐speaking children and research in children's internal state comprehension. Further, children's category scores proved to be developmentally stable. Finally, with increasing age, children's category scores became more specifically related to each other, independent of general language skills. The results are discussed in regard to the universality of children's talk about the mind. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

The current study examined gender differences in mothers' and fathers' internal state language (ISL), children's use of ISL, and whether ISL was related to parents' ratings of the children's social skills. Fifty‐seven (28 boys, 29 girls) toddler/preschool children (M age = 32.5 months, SD = 5.38 months) were observed separately with their mothers and fathers in their homes while they discussed pictures of children's facial expressions of emotions. Parents completed a questionnaire concerning their child's social–emotional behaviours (i.e. BASC‐2). Parents used more ISL with sons compared with daughters, and sons used more ISL with mothers than with fathers. No overall differences were found between mothers' and fathers' ISL. Children's social skills as rated by mothers were predicted by mothers' ISL comments, whereas children's social skills as rated by fathers were predicted by children's age and fathers' ISL clarifications. Implications and limitations of the study are discussed. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

To date, various measurement approaches have been proposed to assess emotional intelligence (EI). Recently, two new EI tests have been developed based on the situational judgment test (SJT) paradigm: the Situational Test of Emotional Understanding (STEU) and the Situational Test of Emotion Management (STEM). Initial attempts have been made to examine the construct‐related validity of these new tests; we extend these findings by placing the tests in a broad nomological network. To this end, 850 undergraduate students completed a personality inventory, a cognitive ability test, a self‐report EI test, a performance‐based EI measure, the STEU, and the STEM. The SJT‐based EI tests were not strongly correlated with personality and fluid cognitive ability. Regarding their relation with existing EI measures, the tests did not capture the same construct as self‐report EI measures, but corresponded rather to performance‐based EI measures. Overall, these results lend support for the SJT paradigm for measuring EI as an ability.  相似文献

Although past research provided some clues about the relation of language use with mental health, the mediatory functions of personality variables in this relationship have been ignored. This research examined the mediatory role of self‐concept clarity in the relationship between language use perceived by individuals and mental health indicators including anxiety, depression, and alexithymia. Based on the theoretical framework suggested by ?im?ek (2010), two studies sought to test two alternative structural equation models in data from university students in the first study (n = 250) and data from other groups in the second study (n = 331). The first model assumed that the relationship of language use with anxiety, depression, and alexithymia was mediated by self‐concept clarity. The second model tested the mediatory role of both anxiety and self‐concept clarity in this relationship. The results of the first study showed that the second model fitted better to the data than the first. Consistent with the first study, the results of the second study confirmed that the second model produced better goodness of fit statistics than the first model.  相似文献
