Executive function is foundational for cognitive development. Previous research has shown both gross motor skills and physical activity to be related to executive function. However, evidence for these relationships in the preschool years, as well as in low‐ and middle‐income countries is lacking. Therefore, this study aimed to investigate the relationships between components of executive function (inhibition, shifting and working memory) and gross motor skills (locomotor skills and object control skills) in a sample of preschool children from urban and rural low‐income settings in South Africa. Results revealed that inhibition and working memory, but not shifting, were associated with gross motor skills. More specifically: inhibition was associated with both locomotor [β = 0.20, p = 0.047] and object control skills [β = 0.24, p = 0.024], whereas working memory was only associated with locomotor skills [β = 0.21, p = 0.039]. Physical activity was not associated with inhibition and shifting but was negatively associated with working memory. These results elaborate a growing evidence base linking executive function and gross motor skills in the early years, and it is the first to look at specific associations of locomotor and object control skills with executive function in the South African context (a low‐ and middle‐income country). 相似文献
In this longitudinal study, we assessed 88 Hong Kong Chinese typically developing kindergarteners' Chinese character reading accuracy four times with 6‐month intervals over 1.5 years with the first testing point in the fall of the second year of kindergarten (K2), during which morphological awareness, phonological awareness, orthographic awareness, visual–spatial relationships, and nonverbal IQ were tested (Time 1). The latent growth curve modeling showed that reading development in Chinese of typically developing kindergarteners followed a cumulative linear trajectory, suggesting that children with higher initial reading ability develop reading ability at a faster rate. Additionally, morphological awareness at K2 positively and uniquely predicted a linear growth pattern of character reading between K2 and K3 over 1.5 years, a period in which formal teaching and learning Chinese takes place in Hong Kong. Contributing to the literature, these findings highlighted the unique significance of morphological awareness in the growth rate of reading: Typically developing children with better early morphological awareness tend to have a higher initial point of reading ability and, more importantly, a faster growth rate, resulting in a wider discrepancy of developmental outcomes between low‐ and high‐ performers. The results suggest that greater attention should be focused on the development of morphological awareness in early readers, given its salient role in Chinese reading development. 相似文献
This study used a novel approach to examine the link between gender ability stereotype endorsement and academic interests by examining not only stereotypes people hold within the domains of mathematics and language arts, but also between them. Grade 6 and 8 students (285 males, 363 females) reported their degree of stereotype endorsement and interest in these two academic domains. Results of path analyses revealed that stereotype endorsement within and between domains accounted for gender differences in interest. In language arts, endorsing a stereotype that females are more competent than males predicted subsequent interest in the domain and accounted for the greater language arts interest among females. In mathematics, however, the perception that males are more competent in mathematics relative to language arts was linked to students’ interest in this domain and accounted for the interest gap between genders. These results suggest that students’ interests relate to endorsed stereotypes that are either driven by a perceived gender superiority within one domain—when females are viewed as more competent than males in language arts—or a gender superiority between two domains—when males are viewed as more competent in mathematics relative to language arts. Considering not only stereotypes favoring a gender within one domain, but also between domains, provides a more accurate portrait of students’ actual stereotypes and can be useful to better understanding how the interest gap emerges.

There has been some debate about whether infants 10 months and younger can use featural information to individuate objects. The present research tested the hypothesis that negative results obtained with younger infants reflect limitations in information processing capacities rather than the inability to individuate objects based on featural differences. Infants aged 9.5 months saw one object (i.e. a ball) or two objects (i.e. a box and a ball) emerge successively to opposite sides of an opaque occluder. Infants then saw a single ball either behind a transparent occluder or without an occluder. Only the infants who saw the ball behind the transparent occluder correctly judged that the one-ball display was inconsistent with the box-ball sequence. These results suggest that: (a) infants categorize events involving opaque and transparent occluders as the same kind of physical situation (i.e. occlusion) and (b) support the notion that infants are more likely to give evidence of object individuation when they need to reason about one kind of event (i.e. occlusion) than when they must retrieve and compare categorically distinct events (i.e. occlusion and no-occlusion). 相似文献
The authors examine the effectiveness of norm misperception education in decreasing disordered eating. One hundred seven 1st-year college women completed questionnaires assessing their own and others' actual and ideal body size as well as their own disordered eating and were then randomly assigned to read either a norm misperception or a control brochure. Participants completed questionnaires immediately after reading the brochures and again 3 months later. Although there were no main effects of brochure condition at the follow-up, participants who primarily compared themselves with other college women and who read the norm misperception brochure had higher actual and ideal weight as well as less frequent disordered eating. The discussion focuses on the theoretical and applied implications of these findings. 相似文献
Teacher preparation programs are under scrutiny for their role in the troubled American educational system. If American education is to improve, teacher educators must identify and encourage teachers to use effective teaching practices. A promising technique for increasing use of teaching practices is providing feedback to teachers on newly acquired behaviors. The focus of this study was to examine the effects of immediate corrective feedback on one specific teaching behavior, use of three-term contingencies, to preservice teachers. A multiple baseline design across participants was used to evaluate the effects of immediate corrective feedback, delivered via a wireless FM listening system. Immediate corrective feedback (as compared with delayed feedback) was shown to be an effective way to increase preservice teacher completion of three-term contingency trials by all participants. These findings and other considerations for additional research using feedback are addressed. 相似文献
