ABSTRACT— Teaching others effectively may rely on knowledge about the mind as well as self-control processes. The goal of this investigation was to explore the role of theory of mind (ToM) and executive function (EF) in children's developing teaching skills. Children 3.5–5.5 years of age ( N = 82) were asked to teach a confederate learner how to play a board game and were administered multitask batteries of ToM and EF with mental age, sex, and memory capacity as controls. There was a developmental increase in children's teaching skills (e.g., older children taught longer, explained more rules, and used more strategies when teaching). Examined separately, both ToM and EF explained unique variance in teaching skills over and above controls. Taken together, EF was a significant predictor of teaching efficacy over and above ToM and controls, whereas the same did not hold true for ToM. These results suggest that ToM may be a necessary prerequisite for teaching to occur; however, EF skills appear to play a vital role in children's teaching efficacy.  相似文献

ABSTRACT

The demands on mathematical problem-solving have increased in almost all school systems internationally and may constitute a barrier for children with special educational needs (SEN). This study explored the role of fluid reasoning (FR), working memory (WM) and complex executive function of planning (EF) in children (N = 62) referred for assessment of SEN, and specifically of risk for mathematical difficulties (MD). Performances on FR, WM and complex EF of planning were used to predict risk for MD. Results showed that planning ability predicted children at risk for MD, beyond FR or WM ability, when comparing with children not at risk for MD. It was concluded that assessing the complex EF of planning in addition to FR and WM ability is crucial in identifying children at risk for MD. The importance of understanding how planning ability affects children’s mathematical problem-solving is discussed, in relation to assessment and teaching practices.  相似文献

Numerous studies suggest an association between language and executive function (EF), but evidence of a developmental relationship remains inconclusive. Data were collected from 75 deaf/hard-of-hearing (DHH) children and 82 hearing age-matched controls. Children were 6–11 years old at first time of testing and completed a battery of nonverbal EF tasks and a test of expressive vocabulary. These tasks were completed again 2 years later. Both groups improved their scores on all tasks over this period. DHH children performed significantly less well than hearing peers on some EF tasks and the vocabulary test at both time points. Cross-lagged panel models showed that vocabulary at Time 1 predicted change in EF scores for both DHH and hearing children but not the reverse.  相似文献

Using an epidemiological sample (N = 1,117) and a prospective longitudinal design, this study tested the direct and indirect effects of preverbal and verbal communication (15 months to 3 years) on executive function (EF) at age 4 years. Results indicated that whereas gestures (15 months), as well as language (2 and 3 years), were correlated with later EF (φs ≥ .44), the effect was entirely mediated through later language. In contrast, language had significant direct and indirect effects on later EF. Exploratory analyses indicated that the pattern of results was comparable for low‐ and not‐low‐income families. The results were consistent with theoretical accounts of language as a precursor of EF ability, and highlighted gesture as an early indicator of EF.  相似文献

Despite the extensive research demonstrating the importance of child executive functioning (EF) for school adjustment, little longitudinal work has formally examined developmental change in EF during the early school years. Based on a sample of 106 mother–child dyads, the current longitudinal study investigated patterns of growth in child performance on three executive tasks between kindergarten (Mage = 6 years) and Grade 3 (Mage = 9 years), and the predictive role of earlier mother–child attachment security in these patterns. The results suggest that early elementary school is a period of significant developmental improvement in child EF, although child performance on different EF tasks follows distinct trajectories across time. The study also provides evidence for a sustained relation between children's early attachment security and their ongoing acquisition of executive skills.  相似文献

The prefrontal cortex modulates executive control processes and structurally matures throughout adolescence. Consistent with these events, prefrontal functions that demand high levels of executive control may mature later than those that require working memory but decreased control. To test this hypothesis, adolescents (9 to 20 years old) completed nonverbal working memory tasks with varying levels of executive demands. Findings suggest that recall-guided action for single units of spatial information develops until 11 to 12 years. The ability to maintain and manipulate multiple spatial units develops until 13 to 15 years. Strategic self-organization develops until ages 16 to 17 years. Recognition memory did not appear to develop over this age range. Implications for prefrontal cortex organization by level of processing are discussed.  相似文献

Executive function (EF) encompasses higher-order mental processes necessary for the conscious control of thought and action in the service of goals. Once thought not to apply to children at all, EF is now at the center of a burgeoning body of research on young children over the last 10–15 years indicating that it is a critical foundation of school readiness and performance. Despite the widely agreed relevance of EF to the transition to formal learning, findings have not yet been applied to preschool classrooms in any widespread way. Part of the reason for this is that despite general agreement on the broad definition of EF, the subdomains EF comprises—especially in early life while it is emerging—are still a matter of debate. It is therefore a challenge to bring the relevant concepts down to an even further level of granularity, i.e., specific behaviors ecologically grounded in everyday preschool interactions. We took the initial steps of this challenge by curating EF-related behaviors from the extant literature, expert and master teacher interviews, and observations in high-quality preschool classrooms into a new protocol called Preschool-Setting Executive Function. This observational system includes child behaviors as well as teacher support behaviors that encourage children’s organized, higher-order thinking. We then employed the final protocol in an additional set of classrooms to provide an initial assessment of its usefulness in identifying “EF in context.” Results indicate (1) EF and EF-support behaviors are low-frequency occurring, (2) children are more engaged in organized thinking than teachers are in the support of it, (3) teachers’ presence, especially if they are expanding play, promotes children’s real-time EF-behaviors. Results are discussed in terms of how this system may be used as a basis for future professional development to enhance teacher practice around the promotion of EF.  相似文献

This study examined age-related changes in complex executive function (EF) in a large, representative sample (N = 2,036) aged 5 to 17 using the Cognitive Assessment System (CAS; Naglieri & Das, 1997a). Relations between complex EF and academic achievement were examined on a sub-sample (N = 1,395) given the Woodcock-Johnson Tests of Achievement-Revised (Woodcock & Johnson, 1989). Performance on the three complex EF tasks improved until at least age 15, although improvement slowed with increasing age and varied some across tasks. Moreover, the different developmental patterns in the correlations between completion time and accuracy provide clues to developmental processes. Examination of individual achievement subtests clarified the specific aspects of academic performance most related to complex EF. Finally, the correlation between complex EF and academic achievement varied across ages, but the developmental pattern of the strength of these correlations was remarkably similar for overall math and reading achievement, suggesting a domain-general relation between complex EF and academic achievement.  相似文献

This study examined the extent to which executive function (EF) mediated associations of socioeconomic status (SES) and home-environment quality with academic readiness (math, letter and word identification, and knowledge of story-and-print concepts). Forty-nine 54–66-month old children and their mothers participated in a home observation and laboratory visit. Hierarchical regression analyses revealed the EF mediated associations between SES and math outcomes. These findings were observed after controlling for child verbal abilities. Implications for the role of verbal ability in EF, the developmental context in predicting EF, and the influence of EF on academic readiness are discussed.  相似文献

Executive functioning (EF) is a key cognitive process for development. Little is known about EF in Kindergarten children at risk for developmental coordination disorder (DCD), despite this age being one of the most critical and intensive period of motor and cognitive development. In our investigation we compared EF in kindergarten children at risk for DCD with Typically Developing (TD) children. Participants were 36 Italian children, 18 at risk for DCD (9 boys and 9 girls) who had a mean age of 4.6 years and 18 TD (9 boys and 9 girls) who had a mean age of 4.6. Executive functions were measured by tasks targeting cold executive functioning (working memory, fluency, inhibitory control) and two assessments of hot executive functioning (Snack Delay and Gift Wrap). Significant differences were found between children at risk for DCD and TD children on cold EF tasks of visuo-spatial working memory abilities, fluency and inhibitory control, but not on hot EF tasks. The findings suggest that it is advisable to implement preschool cognitively challenging physical activities programmes.  相似文献

The current study investigated the extent to which executive functions (EF) affect how prior knowledge predicts hypermedia learning outcomes in primary school children. Learning outcomes were: individual knowledge and transfer, and dyadic assignment quality. Eighty-seven same-sex dyads participated in a hypermedia WebQuest assignment about the heart and living a healthy lifestyle. EF measures were action control and attention control. Dyadic analyses were performed using actor-partner interdependence models with dyads distinguished by EF. Analyses showed that one's own pre-test predicted one's own and partner's post-test for both higher and lower EF dyad members. Furthermore, for dyad members with relative higher EF only, their own and partner's pre-test predicted transfer. Finally, the lower action control dyad member's pre-test and the higher attention control dyad member's pre-test predicted assignment quality. These results show the importance of EF and prior knowledge for deeper conceptual understanding in a collaborative learning setting.  相似文献

The purpose of this study was to examine what components of executive function (EF) – inhibition, shifting and updating/working memory – predict reading comprehension in young adults. Ninety university students (65 females, 25 males; mean age = 21.82 years) were assessed on shifting (Planned Connections and Colour/Shape Shifting), inhibition (Colour‐Word Stroop and Number Stroop), updating/working memory (Digit Memory and Listening Span), reading fluency (Word Reading Efficiency), vocabulary (Peabody Picture Vocabulary Test), and reading comprehension (Nelson‐Denny Reading Test). The results of path analysis indicated that only shifting predicted directly reading comprehension. These findings extend those of previous studies showing that different EF components predict different reading outcomes and suggest that EF has a place in reading comprehension models over and above traditional predictors of reading comprehension such as reading fluency and vocabulary.  相似文献

The association between executive function (EF) and theory of mind (ToM) has been hotly debated for 20 years. Competing accounts focus on: task demands, conceptual overlap, or functional ties. Findings from this meta‐analytic review of 102 studies (representing 9,994 participants aged 3–6 years) indicate that the moderate association between EF and one key aspect of ToM, false belief understanding (FBU) is: (a) similar for children from different cultures, (b) largely consistent across distinct EF tasks, but varies across different types of false belief task, and (c) is asymmetric in that early individual differences in EF predict later variation in FBU but not vice versa. These findings support a hybrid emergence‐expression account and highlight new directions for research.  相似文献

Executive functioning (EF) is a strong predictor of children's and adolescents' academic performance. Although research indicates that EF can increase during childhood and adolescence, few studies have tracked the effect of EF on academic performance throughout the middle school grades. EF was measured at the end of Grades 6–9 through 21 teachers' and 22 teacher assistants' assessments of 322 adolescents from disadvantaged backgrounds who attended an urban, chartered middle/high school. Assessment of EF was done through the completion of the Behavior Rating Inventory of Executive Function (BRIEF). BRIEF global executive composite scores (GEC) predicted both current and future English/language arts, mathematics, science, social studies, and Spanish annual grade point averages (GPAs). The effect of BRIEF GEC scores often overshadowed the effects of gender, poverty, and having an individual education plan; the other, non–BRIEF-related effects retained slightly more impact among teacher assistant–derived data than teacher-derived data. The strong relationships between BRIEF GEC scores and these GPAs also remained constant over these 4 years: There was little evidence that EF changed over the measured grades or that the relationship between EF and grades itself regularly changed. The findings indicate that EF scores during early middle grades can well predict academic performance in subsequent secondary-school grades. Although methodological constraints may have impeded the abilities of other factors (i.e., poverty) to be significantly related to GPAs, the effects of EF were strong and robust enough to prompt us to recommend its use to guide long-term, academic interventions.  相似文献

Abstract

The present study aimed to examine the potential importance of orthographic flexibility for Chinese reading acquisition. Orthographic flexibility is a novel concept that represents the ability to manage and switch attention among multiple aspects of orthographic information. A total of 92 Chinese kindergarten children at age 6 were assessed on measures of orthographic flexibility, orthographic knowledge, executive functions (EF) skills (i.e. cognitive flexibility and working memory) and Chinese word reading. Results of hierarchical regressions showed that orthographic flexibility uniquely and significantly contributed to word reading beyond the effects of established predictors, namely orthographic knowledge and EF skills. Path analysis further indicated that orthographic flexibility significantly mediated the contribution of EF skills to word reading. These findings provided theoretical insights into the linkage between domain-general EF skills and domain-specific reading ability. The present study also provided practical implication that training on orthographic flexibility in addition to orthographic knowledge could be beneficial to early acquisition of Chinese word reading.  相似文献

Longitudinal data were obtained from 157 children aged 3 years 3 months to 5 years 6 months at Time 1. At Time 2 these children had aged an average of 12 months. Theory of mind (ToM) and executive functioning (EF) were measured at both time points. Results suggest that Time 1 ToM scores predict Time 2 EF scores. Detailed examination of sibling influences suggests that benefits—in terms of advanced ToM development—accrue to children with siblings versus without, and to those with a larger number of child‐aged siblings. Any advance in either area (ToM or EF) is likely to benefit the other, and early sibling interaction appears to act as a catalyst.  相似文献

This study investigated relationships between SRL and EF in a sample of 254 school-aged adolescent males. Two hypotheses were tested: that self-reported measures of SRL and EF are closely related and that as different aspects of EF mature during adolescence, the corresponding components of SRL should also improve, leading to an age-related increase in the correlation between EF and SRL. Two self-report instruments were used: the strategies for self-regulated learning survey (SSRLS) and the behavioural rating instrument of executive function (BRIEF). Strong correlations between the measures of EF and SRL were found, especially in areas associated with metacognitive processes. Correlations between EF and SRL were found, with weaker correlations between behavioural regulation and SRL were found to be weaker for the younger participants in the sample while the relationship between EF and SRL appears to grow stronger during the initial years of high school even though self-reported levels of EF along with motivation for SRL and important components of SRL such as goal setting and planning were found to decrease with age. Decreasing levels of motivation for learning during adolescence are speculated to moderate the deployment of SRL and EF in a school context.  相似文献

Studies have suggested that language and executive function (EF) are strongly associated. Indeed, the two are difficult to separate, and it is particularly difficult to determine whether one skill is more dependent on the other. Deafness provides a unique opportunity to disentangle these skills because in this case, language difficulties have a sensory not cognitive basis. In this study, deaf (n = 108) and hearing (n = 125) children (age 8 years) were assessed on language and a wide range of nonverbal EF tasks. Deaf children performed significantly less well on EF tasks, even controlling for nonverbal intelligence and speed of processing. Language mediated EF skill, but the reverse pattern was not evident. Findings suggest that language is key to EF performance rather than vice versa.  相似文献

Intact and Impaired Memory Functions in Autism   总被引：21，自引：0，他引：21  
This study examined memory functions in individuals with autism. Based on previous evidence of executive function (EF) deficits, we hypothesized that subjects with autism would demonstrate a pattern of intact and imparred memory functions similar to that found in other groups with EF deficits, such as patients with frontal lobe pathology. We compared the performance of high-functioning children and adolescents with autism (n = 19) and clinical comparison subjects (n = 19) matched on sex, CA, and VIQ on measures of memory and EF. The group with autism performed significantly worse than comparison subjects on measures of temporal order memory, source memory, supraspan free recall, working memory, and EF, but not on short- and long-term recognition, cued recall, or new learning ability, consistent with the predictions of the EF theory. The cognitive measures were significantly more intercorrelated in the autism group than the comparison group, consistent with a limit in central cognition.  相似文献

There is substantial variance in the age at which children construct and deploy their first explicit theory of biology. This study tests the hypothesis that this variance is due, at least in part, to individual differences in their executive function (EF) abilities. A group of 79 boys and girls aged 5–7 years (with a mean age of 6½ years) were presented with two test batteries: (a) a biology battery that probed their understanding of life, death, and body functions and (b) an EF battery that tested working memory, inhibition, and set‐shifting skills. Individuals' EF scores significantly predict their biology scores, even after controlling for age and verbal IQ.  相似文献
