Previous research has clearly demonstrated that autism spectrum disorder (ASD) involves deficits in multiple neuropsychological functions, such as executive function (EF) and theory of mind (ToM). A conceptual distinction is commonly made between cool and hot EF. In ASD, continued attention has been paid to the cool areas of executive dysfunction. Cool EF has been strongly related to ToM, but research has not taken into account the association between hot EF and ToM in ASD. The present study investigated the associations between hot and cool EF and ToM in 56 school-aged children with ASD and 69 controls on tasks tapping cool EF (i.e., working memory, inhibition, planning), hot EF (i.e., affective decision making, delay discounting), and ToM (i.e., mental state/emotion recognition and false belief). Significant group differences in each EF measure support an executive dysfunction in both domains in ASD. Strong associations between delay discounting and ToM mental state/emotion recognition were found, suggesting that hot EF makes a unique contribution to ToM above and beyond cool EF in typical development and ASD. This study improves understanding of the profile of higher-order cognitive deficits in children with ASD, which may inform diagnosis and intervention.  相似文献

Executive function (EF) has been implicated in childhood aggression. Understanding of the role of EF in aggression has been hindered, however, by the lack of research taking into account the function and form of aggression and the almost exclusive focus on cool EF. This study examined the role of cool and hot EF in teacher reported aggression, differentiating between reactive and proactive as well as physical and relational aggression. Children (N = 106) completed laboratory tasks measuring cool (inhibition, planning, working memory) and hot EF (affective decision‐making, delay of gratification). Cool, but not hot, EF significantly contributed to understanding of childhood aggression. Inhibition was a central predictor of childhood aggression. Planning and working memory, in contrast, were significant independent predictors of proactive relational aggression only. Added to this, prosocial behaviour moderated the relationship between working memory and reactive relational aggression. This study therefore suggests that cool EF, particularly inhibition, is associated with childhood aggression across the different functions and forms.  相似文献

The main objective of this study is to investigate memory task performance in different age groups, irrespective of hearing status. Data are collected on a short-term memory task (WAIS-III Digit Span forward) and two working memory tasks (WAIS-III Digit Span backward and the Reading Span Test). The tasks are administered to young (20–30 years, n = 56), middle-aged (50–60 years, n = 47), and older participants (70–80 years, n = 16) with normal hearing thresholds. All participants have passed a cognitive screening task (Montreal Cognitive Assessment (MoCA)). Young participants perform significantly better than middle-aged participants, while middle-aged and older participants perform similarly on the three memory tasks. Our data show that older clinically normal hearing persons perform equally well on the memory tasks as middle-aged persons. However, even under optimal conditions of preserved sensory processing, changes in memory performance occur. Based on our data, these changes set in before middle age.  相似文献

This study tests the factor structure, measurement invariance, and correlates of the Childhood Executive Functioning Inventory (CHEXI) with a large and diverse sample of 3- to 5-year-olds (n = 844). Consistent with previous studies, a two-factor model that distinguishes working memory from inhibition provides the best fit to the observed data. This two-factor model has been shown to demonstrate strong measurement invariance for different subgroups of children (boys vs. girls, high vs. low income). Whereas boys tend to have greater working memory and inhibition difficulties (Cohen’s d = 0.15 and 0.20, respectively), children from low-income households tend to have more working memory problems than their peers from high-income households (Cohen’s d = 0.25). Finally, correlations between CHEXI scores, examiner reports of child behavior, and child performance on a battery of executive function (EF) tasks were investigated. CHEXI scores were found to be more consistently related to examiner reports of child behavior than child performance on EF tasks. Tthe strengths and weaknesses of the CHEXI as a questionnaire measure of EF are discussed, and directions for future research are suggested.  相似文献

Interrelations of two measurement methods (cognitive versus behavioral ratings) for executive function (EF) were examined and related to reading comprehension and math calculations in fourth and fifth grade students (n = 93) in the context of a diverse urban student population. Relations among measures within four EF processes (working memory, planning, inhibition and shifting) were modest; relations to academics were stronger. EF measures contributed to both academic outcomes even in the context of relevant covariates (age, language and educational program). Working memory was particularly important for reading comprehension across measurement type. Cognitive measures from all EF processes, particularly inhibition and planning, and behavioral ratings of working memory were important for math.  相似文献

The present study investigated sensitivity to age differences in a novel executive function (EF) battery for children aged 18 months to 5 years, and whether the pattern of associations among the measures was consistent with a hierarchical model of EF development. Participants (n = 261, aged 18–67 months) were administered a battery of novel tasks designed to assess 3 key EF components (working memory, inhibition, and shifting). The results indicate that the EF tasks were sensitive to age differences and provide partial support for the hierarchical model of EF development.  相似文献

This report provides evidence of the influence of a tutorial “communication game” on fifth graders’ generative understanding of the integer number line. Students matched for classroom and pretest score were randomly assigned to a tutorial (n = 19) and control group (n = 19). The tutorial group students played a 13-problem game in which student and tutor each were required to mark the same position on a number line but could not see one another's activities. To resolve discrepant solutions, tutor and student constructed agreements about number line principles and conventions to guide subsequent placements. Pre-/posttest contrasts showed that (a) tutorial students gained more than controls and (b) agreement use predicted gain. Analyses of micro-constructions during play revealed properties of student learning trajectories.  相似文献

Three experiments reported here uniquely test the effectiveness of warm versus competent advertising strategy as a function of congruence with other elements of the advertising context. These are product involvement (Experiment 1, n = 96), consumers’ smartphone anxiety (Experiment 2, n = 60), or self-versus other-profitability (Experiment 3, n = 100). As expected, the “golden quadrant” (optimum warmth and competence for advertising effectiveness) does shift: Competence is more important for high-involving products, but warmth wins for highly anxious participants or when the highly involving service is accompanied by people-focused appeals. An expansion of the stereotype content model is discussed in the context of the congruity principle.  相似文献

Executive function (EF) deficit is a hallmark of Fetal Alcohol Spectrum Disorders (FASD), but the vast majority of available evidence comes from school-age children and adolescents. Very little is known about EF during the critical developmental period prior to 6 years of age in FASD. We evaluated EF in 39 children with FASD (3.0–5.5 years) and a comparison group of 50 age-matched, nonexposed controls. Measures included the EF Scale for Early Childhood and a Delay of Gratification task. Compared to age-matched controls, preschool children with FASD had impairments on the EF Scale and showed more impulsivity on the Delay of Gratification task. To confirm the EF Scale finding, FASD group performance was compared to a separate normative dataset (N = 1,400). Those with FASD performed below normal (M = –0.57, SD = 0.92). Within the FASD group, IQ was correlated with the EF Scale (partial = .60, = .001) and Delay of Gratification (partial = .58, = .005). EF Scale performance did not differ significantly across levels of FASD severity (fetal alcohol syndrome [FAS], partial FAS, or alcohol-related neurobehavioral disorder [ARND]). However, compared to normative data, those with FAS had the largest deficits (= –0.91 SD from the mean, SE = 0.23), followed by partial FAS (= –0.66 SD from the mean, SE = 0.26), then ARND (= –0.36 SD from the mean, SE = 0.20). These novel data show that EF deficits manifest well before the age of 6 years in children with FASD, that they occur across the spectrum, and that EF may be most impaired in children with more severe forms of FASD and/or lower IQs.  相似文献

Several studies find that male individuals are more altruistic toward attractive women, suggesting altruism may serve as a courtship display. Many studies exploring this phenomenon have used vignettes and facial images. We tested the sexual selection hypothesis as an explanation for altruistic behavior, where players played the dictator game with “live” participants. Two studies were conducted (Study 1, n = 212; Study 2, n = 188) where we manipulated stakes and anonymity between participants to explore the relationship between the dictator’s allocations and their perceived attractiveness of the recipient. We found no relationship between attractiveness and altruism. Dictators were consistently fair when allocating stakes, irrespective of the recipients’ attractiveness.  相似文献

The present study aims to assess how the processing of basic visual perceptual (VP) components (length, surface, orientation, and position) develops in typically developing (TD) children (n = 215, 4–14 years old) and adults (n = 20, 20–25 years old), and in children with cerebral palsy (CP) (n = 86, 5–14 years old) using the first four subtests of the Battery for the Evaluation of Visual Perceptual and Spatial processing in children. Experiment 1 showed that these four basic VP processes follow distinct developmental trajectories in typical development. Experiment 2 revealed that children with CP present global and persistent deficits for the processing of basic VP components when compared with TD children matched on chronological age and nonverbal reasoning abilities.  相似文献

Relatively little is known about episodic memory (EM: memory for personally-experienced events) and prospective memory (PM: memory for intended actions) in children born very preterm (VP) or with very low birth weight (VLBW). This study evaluates EM and PM in mainstream-schooled 7- to 9-year-olds born VP (≤ 32 weeks) and/or VLBW (< 1500 g) and matches full-term children for comparison (= 35 and = 37, respectively). Additionally, participants were assessed for verbal and non-verbal ability, executive function (EF), and theory of mind (ToM). The results show that the VP/VLBW children were outperformed by the full-term children on the memory tests overall, with a significant univariate group difference in PM. Moreover, within the VP/VLBW group, the measures of PM, verbal ability and working memory all displayed reliable negative correlations with severity of neonatal illness. PM was found to be independent of EM and cognitive functioning, suggesting that this form of memory might constitute a domain of specific vulnerability for VP/VLBW children.  相似文献

The primary aim of the present 1-year longitudinal study among university employees (N = 1314) was to investigate individual development of perceived employability (PE) by utilizing a person-centred approach. Thus, we identified latent classes of PE across 1 year based on growth mixture modelling. In addition, the latent classes were characterized by perceived job insecurity and the type of employment contract and its changes over the 1-year time period. The results showed four latent classes of PE that differed in the level and the direction of mean-level changes over time. These latent classes were: (1) stable relatively high PE (n = 641); (2) unstable decreasing PE (n = 45); (3) unstable increasing PE (n = 24); and (4) stable relatively low PE (n = 603). Perceived job insecurity associated with the latent class membership of PE. That is, low levels of perceived job insecurity were associated with favourable PE classes (i.e., “stable relatively high” and “unstable increasing employability”), whereas high levels of job insecurity associated with unfavourable PE classes (i.e., “stable relatively low” and “unstable decreasing employability”). Furthermore, transitions from temporary to permanent job contract occurred more often in the favourable than in unfavourable PE classes, but transitions from permanent to temporary contract were more likely in the unfavourable classes. Thus, our study indicated a substantial amount of heterogeneity in the development of PE across 1 year.  相似文献

The role of focusing 4-year-olds' attention on “feeling” or “looking” was examined in three experiments by testing predictions about children's memory for their interactions with an adult partner as they engaged in a collaborative task. Children made collages with an adult partner, and they were later asked to remember who placed the pieces on the collage. Children were more likely to claim they placed pieces actually placed by their partner (Experiments 1, 2, and 3), unless directed to think about how their partner looked when placing the partner's pieces (Experiments 1 and 3). False claims were observed after children were directed to think about how it would “feel” to perform the actions, whether motoric instructions were focused on the self (Experiment 2, N = 48) or partner (Experiment 1, N = 40, and Experiment 3, N = 24). Furthermore, false claims (referred to as I did it errors) were positively associated with accurate collage memory (Experiment 3). These findings suggest that adopting a perspective during encoding that involves “feeling” movements—whether focused on the self or partner—plays an important role in children's memory for collaboration (in this context, memory for contributions made by children or their adult partners to the completion of a collage). A focus on “feeling” may be a way to “enter into” the experiences of another, promoting anticipation and recoding, which may lead to better learning in both collaborative and non-collaborative contexts.  相似文献

The present study examines the role of emotion in the self-critical process of individuals with anger problems. Self-criticism is a prevalent intra-personal feature which greatly impacts an individual’s emotion. So far, it is unclear, which emotions individuals with maladaptive anger experience when they work through their self-criticism. Using a quasi-experimental design, the present study compared n = 23 anger-prone under-graduate students to n = 22 controls on process indices of contempt, fear, shame, anger and global distress, as well as on their access to underlying need, as participants were working through personalized self-critical content. This was achieved using a single-session enactment from emotion-focused therapy, augmented with a standardized procedure for priming participants to focus on their unmet needs. Findings suggested that this work on self-criticism reduced for both groups distress, fear and shame, as well as increased assertive anger (McNemar tests significant at p = .05). More centrally, anger-prone individuals expressed more self-contempt (t(1, 44) = 3.65; p < .05), and they had more difficulty in accessing their underlying need (χ2 = 5.35; p < .05), when compared to controls. These results have implications for clinical work with anger-prone individuals, and clarify key features in the use of enactment interventions when working towards emotional resolution. The present study also demonstrates the use of personalized stimuli in the context of clinically relevant quasi-experimental research on emotional processes.  相似文献

Children are at risk for cognitive difficulties following the diagnosis and treatment of a brain tumor. Longitudinal studies have consistently demonstrated declines on measures of intellectual functioning, and recently it has been proposed that specific neurocognitive processes underlie these changes, including working memory, processing speed, and attention. However, a fine-grained examination of the affected neurocognitive processes is required to inform intervention efforts. Radiation therapy (RT) impacts white matter integrity, likely affecting those cognitive processes supported by distributed neural networks. This study examined working memory and attention in children during the early delayed stages of recovery following surgical resection and RT. The participants included 27 children diagnosed with pediatric brain tumor, treated with (n = 12) or without (n = 15) RT, who completed experimental and standardized measures of working memory and attention (n-back and digit span tasks). Children treated with radiation performed less well than those who did not receive radiation on the n-back measure, though performance at the 0-back level was considerably poorer than would be expected for both groups, perhaps suggesting difficulties with more basic processes such as vigilance. Along these lines, marginal differences were noted on digit span forward. The findings are discussed with respect to models of attention and working memory, and the interplay between the two.  相似文献

We compared trajectories of terminal cognitive decline in older Black (n = 3372) and White (n = 1756) persons from a defined population who completed tests of episodic memory and perceptual speed at 3-year intervals for up to 18 years. During a mean of 9.9 years of observation, 1608 Black persons and 902 White persons died. Preterminal decline of episodic memory did not differ by race. Terminal episodic memory decline began earlier in Black persons (mean of 4.3 years before death) than in White persons (mean = 3.9 years) and progressed more slowly. By contrast, terminal decline of perceptual speed began earlier in White persons (mean = 5.0 years) than in Black persons (mean = 4.5 years). Rate of perceptual speed decline was more rapid in White persons than in Black persons in both the preterminal and terminal periods. The results indicate that terminal cognitive decline occurs in Black persons but suggest that the rate of cognitive decline during the terminal period is less rapid in Black persons than in White persons.  相似文献

Aspects of executive functioning (EF) have been put forward as endophenotypes in obsessive- compulsive disorder (OCD) and meta-analyses support EF underperformance in adult samples. Childhood-onset OCD has been suggested to constitute a separate neurodevelopmental subtype of the disorder but studies on neuropsychological functioning in childhood OCD are limited. The aim of the present study was to investigate performance-based EF in pediatric OCD using observed and latent variable analyses. A case-control design was applied including 50 unmedicated children and adolescents with OCD aged 7–17 years of which 70% were female, 50 pairwise age and gender matched non-psychiatric controls (NP) and 38 children and adolescents with mixed anxiety disorders (MA). Participants underwent structured diagnostic interviews and assessment with a battery encompassing cool EF tasks of working memory, set shifting, inhibition, and planning, and hot EF tasks of decision making and dot probe paradigm affective interference. First, groups were compared on observed variables with multilevel mixed-effects linear regression and analysis of variance. Then the latent structure of cool EF was tested with confirmatory factor analysis (CFA) and groups were compared on the CFA scores. No significant differences between groups appeared on individual cool EF tasks. On the hot EF tasks the OCD group displayed significant interference effects on the dot probe paradigm OCD-specific stimuli relative to NP, but not compared to MA and no group differences emerged for decision making. In the CFA a one-factor solution showed best fit, but the groups did not differ significantly on the resulting latent variable. The present study does not support cool or hot EF impairments in childhood OCD.  相似文献

Several studies suggest impaired executive functions (EFs) in children with externalizing behavior problems and average intelligence (e.g., IQ > 85). Even though children with mild to borderline intellectual disabilities (MBID) are at higher risk of developing externalizing behavior problems compared to children with average intelligence, it is not yet clear if impaired EFs are also associated with the occurrence of externalizing behavior problems in children with MBID. In the current study, we therefore assessed three EF components (inhibition, cognitive flexibility, and working memory) as well as processing speed in children with MBID and externalizing behavior problems (= 71) versus children with MBID with no such problems (= 70). This was accomplished using a well-established computerized test battery. Even after IQ was controlled for, the children with MBID and externalizing behavior problems showed more impaired working memory performance. Differences for inhibition performance and processing speed were also found but less consistent across the tasks used to measure these aspects of EF. Cognitive flexibility was not more impaired in children with both MBID and externalizing behavior problems relative to children with MBID only. Our findings highlight working memory as a potential target to enhance the treatment of children with MBID and externalizing behavior problems.  相似文献

Although cognitive theories of anxiety suggest that anxious individuals are characterized by abnormal threat‐relevant schemas, few empirical studies have estimated the nature of these cognitive structures using quantitative methods that lend themselves to inferential statistical analysis. In the present study, socially anxious (n = 55) and non‐anxious (n = 62) participants completed 3 Q‐Sort tasks to assess their knowledge of events that commonly occur in social or evaluative scenarios. Participants either sorted events according to how commonly they personally believe the events occur (i.e. “self” condition), or to how commonly they estimate that most people believe they occur (i.e. “other” condition). Participants' individual Q‐Sorts were correlated with mean sorts obtained from a normative sample to obtain an estimate of schema abnormality, with lower correlations representing greater levels of abnormality. Relative to non‐anxious participants, socially anxious participants' sorts were less strongly associated with sorts of the normative sample, particularly in the “self” condition, although secondary analyses suggest that some significant results might be explained, in part, by depression and experience with the scenarios. These results provide empirical support for the theoretical notion that threat‐relevant self‐schemas of anxious individuals are characterized by some degree of abnormality.  相似文献
