Executive functions enable flexible thinking, something young children are notoriously bad at. For instance, in the dimensional change card sort (DCCS) task, 3‐year‐olds can sort cards by one dimension (shape), but continue to sort by this dimension when asked to switch (to color). This study tests a prediction of a dynamic neural field model that prior experience with the postswitch dimension can enhance 3‐year‐olds' performance in the DCCS. In Experiment 1A, a matching game was used to preexpose 3‐year‐olds (n = 36) to color. This facilitated switching from sorting by shape to color. In 3 , 3‐year‐olds (n = 18) were preexposed to shape. This did not facilitate switching from sorting by color to shape. The model was used to explain this asymmetry. 相似文献

In laboratory medicine, several studies have described the most frequent errors in the different phases of the total testing process, and a large proportion of these errors occur in the pre-analytical phase. Schemes for registration of errors and subsequent feedback to the participants have been conducted for decades concerning the analytical phase by External Quality Assessment (EQA) organizations operating in most countries. The aim of the paper is to present an overview of different types of EQA schemes for the pre-analytical phase, and give examples of some existing schemes. So far, very few EQA organizations have focused on the pre-analytical phase, and most EQA organizations do not offer pre-analytical EQA schemes (EQAS). It is more difficult to perform and standardize pre-analytical EQAS and also, accreditation bodies do not ask the laboratories for results from such schemes. However, some ongoing EQA programs for the pre-analytical phase do exist, and some examples are given in this paper. The methods used can be divided into three different types; collecting information about pre-analytical laboratory procedures, circulating real samples to collect information about interferences that might affect the measurement procedure, or register actual laboratory errors and relate these to quality indicators. These three types have different focus and different challenges regarding implementation, and a combination of the three is probably necessary to be able to detect and monitor the wide range of errors occurring in the pre-analytical phase. 相似文献

Research Findings: Children's early academic achievement is supported by positive social and behavioral skills, and difficulties with these skills frequently gives way to underachievement. Social and behavioral problems often arise as a product of parent–child interactional patterns and environmental influences. Few studies have examined the role of a salient aspect of children's environments, community locale, in the relationship between parenting practices and child outcomes. Using a large, nationally representative sample, we examined whether preschool parenting practices and children's social-behavioral skills in kindergarten were related to geographic setting (rural vs. city, suburban, and town). Results indicated that rural children experienced greater difficulties with parent-reported externalizing behaviors. Furthermore, rural parents displayed less emotional support than parents in other settings. Preschool parenting behaviors were associated with social skills and behavior problems in kindergarten, as reported by both parents and teachers. Parents' emotional supportiveness was found to account for the relationship between geographic setting and parent-reported children's social skills, such that rural parents who provided less emotional support had children with lower social skills in kindergarten. Practice or Policy: Findings of this research indicate that rural children may face particular risk for behavioral issues and highlight the need for increased behavioral supports in rural communities. Moreover, our results suggest that interventions designed to promote parents' support of children's emotions may have particular utility for rural families. 相似文献

There has been growing interest in the mental health benefits of self‐compassion. This study was designed to establish norms on the Self‐Compassion Scale–Short Form, a popular measure of self‐compassion for individuals seeking counseling, and to examine group differences in self‐compassion based on gender, race/ethnicity, sexual orientation, previous counseling, and psychiatric medication use. Data for this study were collected through the Center for Collegiate Mental Health, a practice‐research network of more than 240 college and university counseling centers. 相似文献

A summarization task was used to study whether headings influence readers' representations of the topic structure of a text. College students (Experiments 1-3) and sixth- and eighth-graders (Experiment 3) summarized a multiple topic text that (a) included headings introducing every new subtopic, (b) included headings introducing half of the new subtopics, or (c) included no headings. In all experiments, topics were more likely to be included in a summary if they were signaled than if they were not signaled. This effect was magnified when the text was only half signaled: Signaled topics were more likely to appear in a summary if only half the text topics were signaled than if all of the topics were signaled; however, unsignaled topics were less likely to appear in a summary if half of the text topics were signaled than if none of the text topics were signaled. The findings demonstrate that readers rely heavily on headings in a task that emphasizes attention to a text's topic structure. It is suggested that previously observed signaling effects on text recall are mediated by effects on how readers represent a text's topic structure. Copyright 2001 Academic Press. 相似文献
