The aim of this study is to investigate whether sluggish cognitive tempo (SCT) symptoms are associated with neurocognitive task performance and ratings of real-world executive functioning (EF) in preschoolers at risk for attention-deficit/hyperactivity disorder (ADHD). The associations between parent- and teacher-rated SCT symptoms and neuropsychological task performance and ratings of EF in 61 4-year-old preschool children (51 boys, 10 girls) with self-regulation difficulties were examined, with regression analyses controlling for the effects of ADHD inattention symptoms. In the study sample, higher teacher-rated SCT symptoms are significantly associated with poorer performance on tasks of visual-perceptual abilities, auditory and visual attention, sustained and selective attention, inhibitory control, pre-numerical/numerical concepts, and slower processing speed, but SCT symptoms are not significantly associated with working memory, attention shifting or cognitive flexibility when controlling for ADHD inattention. Higher parent-rated SCT symptoms are significantly associated with visual-perceptual abilities. ADHD inattention symptoms are more strongly associated than SCT with daily life EF ratings; neither parent- nor teacher-rated SCT symptoms are significantly associated with daily life ratings of inhibition, working memory, or planning/organization after controlling for ADHD inattention. This study suggests that SCT symptoms contribute to EF deficits at least on neurocognitive tasks assessing visual-perceptual/spatial abilities, attention to detail and processing speed, as observed in this sample of young children at risk for ADHD, and may be an important intervention target. 相似文献

We examined the relation between emotion and susceptibility to misinformation using a novel paradigm, the ambiguous stimuli affective priming (ASAP) paradigm. Participants (N = 88) viewed ambiguous neutral images primed either at encoding or retrieval to be interpreted as either highly positive or negative (or neutral/not primed). After viewing the images, they either were asked misleading or non-leading questions. Following a delay, memory accuracy for the original images was assessed. Results indicated that any emotional priming at encoding led to a higher susceptibility to misinformation relative to priming at recall. In particular, inducing a negative interpretation of the image at encoding led to an increased susceptibility of false memories for major misinformation (an entire object not actually present in the scene). In contrast, this pattern was reversed when priming was used at recall; a negative reinterpretation of the image decreased memory distortion relative to unprimed images. These findings suggest that, with precise experimental control, the experience of emotion at event encoding, in particular, is implicated in false memory susceptibility. 相似文献

The goal of this study was to examine the relationship between characteristics of early childhood mental health consultation (ECMHC) and changes in the quality of teacher–child interactions. One hundred forty‐one early childhood teachers, serving 3‐ to 5‐year‐olds in publically funded early education programs in the state of Arkansas, participated in this study. All childcare sites and preschool programs participating in the study received ECMHC through the Arkansas Early Childhood Mental Health Consultation Project over a period of 3 years. Findings from this study suggest that teachers exposed to ECMHC through their employment at one of the project sites made significant gains toward high‐quality teacher–child interactions relative to their initial levels of quality. In particular, delivery aspects of ECMHC and teachers’ experiences of ECMHC predicted change in quality of teacher–child interactions. Findings suggest that ECMHC may be a promising professional development intervention for teachers in early childhood settings and that specific characteristics of consultation may be particularly influential in impacting change in those settings. 相似文献

This study examined the moderating effects of family conflict and gender on the relationship between community violence and
psychosocial development at age 18. The study sample consisted of 728 children and families who were part of the Infant Health
and Development Program study of low-birth-weight, pre-term infants. In this sample, adolescent psychosocial outcomes were
predicted by community violence differently for male and female children and based on their experiences of conflict at home.
For male children, being in a high conflict family as a child exacerbated the negative effects of community violence such that internalizing problems (depression
and anxiety) and risk-taking behaviors increased as community violence increased, while being in a low conflict family protected the child against the negative impacts of the community. For female adolescents, there were no
moderating effects of family conflict on the relationship between community violence and externalizing problems. Moderating
effects for internalizing problems demonstrated that being in low conflict families did not serve as protection against community violence for girls as was demonstrated for boys. These findings
demonstrate the long-term effects of community violence on child development, highlighting the importance of gender and family
context in the development of internalizing and externalizing problems. 相似文献

Although the role of IQ in developmental dyslexia remains ambiguous, the dominant clinical and research approaches rely on a definition of dyslexia that requires reading skill to be significantly below the level expected given an individual's IQ. In the study reported here, we used functional MRI (fMRI) to examine whether differences in brain activation during phonological processing that are characteristic of dyslexia were similar or dissimilar in children with poor reading ability who had high IQ scores (discrepant readers) and in children with poor reading ability who had low IQ scores (nondiscrepant readers). In two independent samples including a total of 131 children, using univariate and multivariate pattern analyses, we found that discrepant and nondiscrepant poor readers exhibited similar patterns of reduced activation in brain areas such as left parietotemporal and occipitotemporal regions. These results converge with behavioral evidence indicating that, regardless of IQ, poor readers have similar kinds of reading difficulties in relation to phonological processing. 相似文献

Saccade stop signal and target step tasks are used to investigate the mechanisms of cognitive control. Performance of these tasks can be explained as the outcome of a race between stochastic go and stop processes. The race model analyses assume that response times (RTs) measured throughout an experimental session are independent samples from stationary stochastic processes. This article demonstrates that RTs are neither independent nor stationary for humans and monkeys performing saccade stopping and target-step tasks. We investigate the consequences that this has on analyses of these data. Nonindependent and nonstationary RTs artificially flatten inhibition functions and account for some of the systematic differences in RTs following different types of trials. However, nonindependent and nonstationary RTs do not bias the estimation of the stop signal RT. These results demonstrate the robustness of the race model to some aspects of nonindependence and nonstationarity and point to useful extensions of the model. 相似文献

In this study we assessed individual differences among preschoolers' emotion understanding, verbal ability, and gender role behavior. Fifty-three children (M = 3 years, 5 months; 26 girls, 27 boys) participated in task that used puppets to assess their understanding of simple (happy, sad) and complex emotions (proud, embarrassed) and a standard vocabulary task. Parents completed a questionnaire on the frequency of their children's gender-typed behavior. Results indicated positive associations between children's total emotion understanding and both general verbal ability (particularly for boys) and parents' perceptions of stereotypic feminine behaviors. Gender analysis revealed that, independent of vocabulary ability, girls scored higher than boys on emotion labeling and understanding of complex emotions, especially the concept of pride. Results are discussed in relation to individual differences and effects of sociocultural context. 相似文献

Research suggests that individual differences in math abilities correlate with approximate representations of quantity that are supported by a primitive Approximate Number System (ANS). However, relatively little research has addressed the direction of this association in early childhood. Here we examined the development of the ANS and math ability longitudinally in 3- to 5-year-old children. Children were observed at three time points roughly six months apart; they completed a nonsymbolic numerical comparison task that measured ANS precision and a standardized math assessment. A series of cross-lagged panel models was then estimated to explore the associations between ANS precision and math ability over time. Bidirectional associations between ANS precision and math ability emerged: Early ANS precision was related to children’s later math skills, and early math ability also significantly predicted children’s later ANS precision. Evidence for mutual enhancement over time between the ANS and symbolic math ability adds to our growing understanding of the ANS and how the ANS and math knowledge interact. 相似文献

The use of multi‐source feedback has proliferated in the United States in recent years; however, its usefulness in other countries is unknown. Using a large sample of American managers (n=3793), this study first replicated earlier studies demonstrating that simultaneous consideration of self and other ratings of leadership skills is important for managerial performance ratings. In addition, the impact of self–other agreement on performance was investigated among 2732 managers in five European countries (U.K., Germany, France, Denmark, Italy). Results indicated that the effect of self and other ratings in the prediction of performance differs between the U.S. and the European countries in that the simultaneous inclusion of both self and other ratings is generally less useful in those countries than in the U.S. Further, the effect of self–other agreement varies among the European countries. Implications for multi‐source feedback interventions as well as multi‐national personnel management are discussed. 相似文献
