Little is known about how components of executive function (EF) jointly and uniquely predict different aspects of academic achievement and how this may vary across cultural contexts. In the current study, 119 Chinese and 139 American preschoolers were tested on a battery of EF tasks (i.e., inhibition, working memory, and attentional control) as well as academic achievement tasks (i.e., reading and mathematics). Results demonstrate that although working memory performance in both cultures was comparable, Chinese children outperformed American children on inhibition and attentional control tasks. In addition, the relation between components of EF and achievement was similar in the two countries. Working memory uniquely predicted academic achievement, with some intriguing patterns in regard to tasks requiring complex processing. Inhibition uniquely predicted counting but did not uniquely predict calculation. Attentional control predicted most aspects of achievement uniformly and was the most robust predictor for reading in both countries. In sum, the data provide insight into both cultural variability and consistency in the development of EF during early childhood. 相似文献

The present research tested the proposition that nostalgia serves an existential function by bolstering a sense of meaning in life. Study 1 found that nostalgia was positively associated with a sense of meaning in life. Study 2 experimentally demonstrated that nostalgia increases a sense of meaning in life. In both studies, the link between nostalgia and increased meaning in life was mediated by feelings of social connectedness. Study 3 evidenced that threatened meaning increases nostalgia. Study 4 illustrated that nostalgia, in turn, reduces defensiveness following a meaning threat. Finally, Studies 5 and 6 showed that nostalgia disrupts the link between meaning deficits and compromised psychological well-being. Collectively, these findings indicate that the provision of existential meaning is a pivotal function of nostalgia. 相似文献

Background. Previous research has found links between being a victim of bullying and reporting more unhealthy eating behaviours and cognitions, particularly in girls. However, little is known about the factors that might mediate these relationships. Aim. The present study compared the relationships between bullying, emotional adjustment, restrained eating, and body dissatisfaction in adolescent boys and girls. Sample/method. Self‐report data were collected from a sample of 11‐ to 14‐year‐olds (N= 376) on experiences of bullying, emotional symptoms, and unhealthy eating and shape‐related attitudes and behaviours. Results. Bullying, emotional symptoms, restrained eating, and body dissatisfaction were all correlated. Emotional symptoms were found to significantly mediate the relationships between verbal bullying with body dissatisfaction in girls but not in boys. Conclusions. Findings suggest that the experience of being verbally bullied places adolescent girls at risk of developing emotional problems which can then lead to body dissatisfaction. Longitudinal research is necessary to disentangle these pathways in more detail to facilitate the development of informed interventions to support children who are being bullied. 相似文献

Measuring behavioral regulation in four societies 总被引:1,自引:0,他引:1

The present study examined the psychometric properties of scores from a direct measure of behavioral regulation, the Head-Toes-Knees-Shoulders task (HTKS) with 3- to 6-year-old children in the United States, Taiwan, South Korea, and China. Specifically, we investigated (a) the nature and variability of HTKS scores, including relations to teacher-rated classroom behavioral regulation; and (b) relations between the HTKS and early mathematics, vocabulary, and literacy skills. Higher HTKS scores were significantly related to higher teacher ratings of classroom behavioral regulation in the United States and South Korea but not in Taiwan and China. Also, higher HTKS scores were significantly related to higher early mathematics, vocabulary, and literacy skills beyond the influence of demographic variables and teacher-rated classroom behavioral regulation. These initial findings suggest that HTKS scores may be interpreted as reflecting early behavioral regulation in these 4 societies and that behavioral regulation is important for early academic success in the United States and in Asian countries. 相似文献

Chaotic home lives are correlated with behavior problems in children. In the study reported here, we tested whether there was a cross-lagged relation between children's experience of chaos and their disruptive behaviors (conduct problems and hyperactivity-inattention). Using genetically informative models, we then tested for the first time whether the influence of household chaos on disruptive behavior was environmentally mediated and whether genetic influences on children's disruptive behaviors accounted for the heritability of household chaos. We measured children's perceptions of household chaos and parents' ratings of children's disruptive behavior at ages 9 and 12 in a sample of 6,286 twin pairs from the Twins Early Development Study (TEDS). There was a phenotypic cross-lagged relation between children's experiences of household chaos and their disruptive behavior. In genetically informative models, we found that the effect of household chaos on subsequent disruptive behavior was environmentally mediated. However, genetic influences on disruptive behavior did not explain why household chaos was heritable. 相似文献

A key criticism of the main diagnostic tool in psychiatry, the Diagnostic and Statistical Manual of Mental Health Disorders (DSM-IV), is that it lacks a biological footing. In this article, we argue for a biological approach to psychiatry based on 'neurocognitive endophenotypes', whereby changes in behavioural or cognitive processes are associated with discrete deficits in defined neural systems. We focus on the constructs of impulsivity and compulsivity as key examples of the approach and discuss their possible cross-diagnostic significance, applying them to co-morbidities and commonalities across a range of disorders (attention-deficit/hyperactivity disorder, substance dependence, obsessive-compulsive disorder and eating disorders). We argue that this approach has important implications for the future classification of psychiatric disorders, genetics and therapeutics. 相似文献

Prior research has established significant relations between measures of sensory ability and cognitive function in adults of different ages, and several explanations for this relation have been proposed. One explanation is that sensory abilities restrict cognitive processing, a second is that cognitive abilities influence assessments of sensory ability, and a third is that both sensory function and cognition are affected by a common, potentially age-based, third factor. These explanations were investigated using mediation and moderation analyses, with near visual acuity as the sensory measure and scores on visual speed tests and auditory memory tests as the cognitive measures. Measures of visual acuity, speed, and memory were obtained from three moderately large samples, two cross-sectional (N?=?380, N?=?4,779) and one longitudinal (N?=?2,258), with participants ranging from 18 to 90 years of age. The visual acuity and cognitive measures had different age trajectories, and the visual acuity–cognition relations were similar in each 5-year age band. The results suggest that the age-related differences and changes in near visual acuity are unlikely to contribute to the age-related differences and changes in speed and memory measures. 相似文献

Many therapists believe clients must pay a fee in order for therapy to be effective. This study conducted a review of 1,125 client records in a southeastern university’s marriage and family therapy training clinic to determine how paying fees impacted therapy attendance and outcomes. The results indicated that the amount of fee paid did not predict therapy attendance or outcomes. These findings, consistent with previous research, suggest that fee payment has limited impact on achievement of therapeutic gains. 相似文献
