Measuring and Predicting Individual Differences in Executive Functions at 14 Months: A Longitudinal Study

This study of 195 (108 boys) children seen twice during infancy (Time 1: 4.12 months; Time 2: 14.42 months) aimed to investigate the associations between and infant predictors of executive function (EF) at 14 months. Infants showed high levels of compliance with the EF tasks at 14 months. There was little evidence of cohesion among EF tasks but simple response inhibition was related to performance on two other EF tasks. Infant attention (but not parent-rated temperament) at 4 months predicted performance on two of the four EF tasks at 14 months. Results suggest that EF skills build on simpler component skills such as attention and response inhibition.     

Expressive Vocabulary Predicts Nonverbal Executive Function: A 2-year Longitudinal Study of Deaf and Hearing Children

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.     

Executive Function and Reading Comprehension: A Meta-Analytic Review

This article presents a meta-analytic review of the relation between executive function and reading comprehension. Results (N = 6,673) supported a moderate positive association between executive function and reading comprehension (r = .36). Moderator analyses suggested that correlations between executive function and reading comprehension did not vary systematically by age range, type of executive function measure used, type of reading comprehension measure used, or whether the study was a dissertation or a published article but did vary by type of executive function examined in the studies. Studies linking specific executive functions with reading comprehension are then reviewed. The article concludes by discussing implications for a theoretical model of reading comprehension as well as for future research.     

Nonverbal Executive Function is Mediated by Language: A Study of Deaf and Hearing Children

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.     

Relations Between False Belief Understanding and Executive Function in Early Childhood: A Meta‐Analysis

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.     

The Function of Executive Function: Everyday Manifestations of Regulated Thinking in Preschool Settings

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.     

浅论汉语的停延规律及其功能

停延是指说话或朗读时语流中声音的中断和延连,它是汉语节律中最基本的特征之一.由于汉字没有词连写的习惯,书面上也缺少停延的标志,如果讲话或朗读时停延不当,便不能确切地表达说话者的思想感情,甚至还会产生歧义.所以本文从停延的种类、规律、功能等几个方面对汉语停延现象进行研究,以期能进一步正确把握汉语节奏规律,从而指导说话与朗读.     

The Effect of Executive Function on Biological Reasoning in Young Children: An Individual Differences Study

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.     

Knowing When to Be “Rational”: Flexible Economic Decision Making and Executive Function in Preschool Children

Failure to delay gratification may not indicate poor control or irrationality, but might be an adaptive response. Two studies investigated 3.5‐ and 4.5‐year‐old children's ability to adapt their delay and saving behavior when their preference (e.g., to delay or not delay) became nonadaptive. In Study 1 (N = 140), children's delay preference was associated with a risk of losing rewards. In Study 2 (N = 142), children's saving preference was associated with an inability to play an attractive game. Whereas baseline delaying and saving preferences were unrelated to a standardized executive function measure, children who switched to their nonpreferred choice scored higher, suggesting flexibility of decision‐making may be a more meaningful dependent variable than baseline performance in developmental research on self‐control.     

False‐Belief Understanding and Social Preference Over the First 2 Years of School: A Longitudinal Study

The role of false belief in establishing children's social relationships during the transition to school was examined and compared to other social cognitive constructs. One hundred and fourteen 5‐year‐olds were recruited during their 1st year of school (Time 1); 106 children were retained 1 year later. False belief, emotion expression recognition, empathy, verbal ability, and peer‐rated social preference were measured at both times. False belief at Time 1 had a direct influence on concurrent social preference, over and above the influence of emotion expression recognition and empathy. False belief made no independent contribution to later social preference accounting for stability in social preference. The role of social cognitive development is discussed with respect to how children establish and maintain their position in a peer group.     

Children's Teaching Skills: The Role of Theory of Mind and Executive Function

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.     

Fear of failure, 2 × 2 achievement goal and self-handicapping: An examination of the hierarchical model of achievement motivation in physical education

In this study, the hierarchical model of achievement motivation [Elliot, A. J. (1997). Integrating the “classic” and “contemporary” approaches to achievement motivation: A hierarchical model of approach and avoidance achievement motivation. In P. Pintrich & M. Maehr (Eds.), Advances in motivation and achievement (Vol. 10, pp. 143–179). Greenwich, CT: JAI Press] is used to investigate the motivational mechanism behind the relationship between fear of failure and self-handicapping adoption. A cross-sectional design was employed. The participants were 691 college students enrolled in physical education in Taiwan. Students completed the Performance Failure Appraisal Inventory (PEAI-S; Conroy, D. E., Willow, J. P., & Metzler, J. N. (2002). Multidimensional measurement of fear of failure: The performance failure appraisal inventory. Journal of Applied Sport Psychology, 14, 76–90), the Chinese 2 × 2 Achievement Goal Questionnaire for Physical Education (CAGQ-PE; Chen, L. H. (2007). Construct validity of Chinese 2 × 2 achievement goal questionnaire in physical education: Evidence from collectivistic culture. Paper presented at the 5th conference of the Asian South Pacific Association of Sport Psychology. Bangkok, Thailand) and the Self-Handicapping Scale (SHS; Wu, C. H., Wang, C. H., & Lin, Y. C. (2004). The exploratory and confirmatory factor analysis of self-handicap scale for sport. Journal of Higher Education in Physical Education, 6(1), 139–148). Structural equation modeling was conducted. Generally, the results showed that mastery-avoidance and performance-avoidance goals partially mediated the relationship between fear of failure and self-handicapping. The results are discussed in terms of the hierarchical model of achievement motivation, and its implications for physical education are also highlighted.
