The development of cognitive control enables children to better resist acting based on distracting information that interferes with the current action. Cognitive control improvement serves different functions that differ in part by the type of interference to resolve. Indeed, resisting to interference at the task‐set level or at the response‐preparation level is, respectively, associated with cognitive flexibility and inhibition. It is, however, unknown whether the same neural mechanism underlies these two functions across development. Studies in adults have revealed the contribution of midfrontal theta (MFT) oscillations in interference resolution. This study investigated whether MFT is involved in the resolution of different types of interference in two age groups identified as corresponding to different latent structures of executive functions. Preschool (4–6 years) and school children (6–8 years) were tested with a task involving interference at the response level and/or the task‐set level while (electroencephalogram) EEG was recorded. Behaviorally, response time and accuracy were affected by task‐set. Both age groups were less accurate when the interference occurred at the task‐set level and only the younger group showed decreased accuracy when interference was presented at the response‐preparation level. Furthermore, MFT power was increased, relative to the baseline, during the resolution of both types of interference and in both age groups. These findings suggest that MFT is involved in immature cognitive control (i.e., preschool and school‐ages), by orchestrating its different cognitive processes, irrespective of the interference to resolve and of the level of cognitive control development (i.e., the degree of differentiation of executive functions).  相似文献

大量从“能力”角度来探讨个体早期数学发展的研究仅专注于儿童早期的数学知识和技能, 而忽略了可能与儿童早期数学能力相关的方面。近年来, 数学认知发展研究者逐渐开始关注自发数量聚焦(Spontaneous focusing on numerosity, SFON), 即个体对环境中数量相关信息自发注意的认知倾向。SFON被视为其他数学聚焦倾向概念的基础, 但与自发数字聚焦(SAN)、自发阿拉伯数字聚焦(SFONS)和自发数量关系聚焦(SFOR)之间的联系仍需进一步明晰。作为数学表现的领域特异预测因子, 个体SFON的发展轨迹和作用机制是当前研究的重点所在。未来可从数学动机、数学焦虑等角度进一步探讨SFON的作用机制, 改良与创新SFON测量工具, 同时需深入推进家庭和学校场合的SFON干预研究。  相似文献

An understanding of the roles and representations of women in classical Chinese philosophy is here derived from central texts such as the Analects, the Lienü Zhuan, and the I Ching. We argue that the roles of women during the classical period of Chinese philosophy tended to be as part of the “inner,” working domestically as a housewife and mother. This will be shown from three passages from the Analects. Women were represented as submissive and passive, as with the qualities ascribed to yin energy, and therefore as rightfully subordinate to men. However, despite representations of women in philosophy being thus at this time, there were exceptions, specific women who could take a male “outer” political role. The story of Jing Jiang from the Lienü Zhuan suggests that although women being involved in “outer” affairs were looked down on, there were still women who would be and who would occasionally get praised for doing so. This shows that it was realized, explicitly or otherwise, that women were capable of taking those roles, but also that they were not allowed to take such roles at that time.  相似文献

Developing mice were growth-retarded by underfeeding of their mothers during lactation. Control mothers were well nourished throughout. All offspring were fed ad libitum from weaning till their behaviour was tested in adulthood. The undernourished mice had weight deficits at weaning of 49% compared with controls. Nevertheless, they showed partial catch-up growth thereafter, in that their absolute weight deficits decreased between weaning and adulthood. Social behaviour observations were made on pairs of mice of the same treatment group. Previously undernourished mice were slower to start attacking one another, spent more time near or in contact with one another and did less tail-rattling than their controls.  相似文献

The primary goals of this study are to describe the nature and severity of disruptive behavior problems in clinic-referred preschoolers from low-income environments and to explore the validity of DSM-IV disruptive disorders for young children. We examine the relation between DSM-IV symptoms, standardized behavior checklists, and observational ratings as a means of exploring measurement validity in this age group. Seventy-nine clinic-referred preschoolers (ages 2 through 5 years) from low-income environments were assessed. To examine whether clinic-referred preschool children have symptoms that are consistent with DSM-IV disruptive behavior disorders, parents were administered a semistructured diagnostic interview, modified for developmentally appropriate usage. In addition, parents completed the Child Behavior Checklist (CBCL) and children's behavior problems were assessed with observational ratings during parent–child interaction. Nearly half of the sample met criteria for conduct disorder, and three quarters met criteria for oppositional defiant disorder. Preliminary evidence for the validity of DSM-IV disruptive disorders in preschool children was demonstrated through association with CBCL scores, behavior ratings, and significant levels of impairment. Future efforts aimed at validating these diagnoses in preschoolers and implications for prevention are discussed.  相似文献

Cognitive deficits associated with early Alzheimers disease (AD) have been recently operationalised in terms of an acquisition deficit and the research supporting this view is presented. However, there is still debate concerning the nature of this deficit and how underlying cognitive processes may be detrimentally affecting the ability to acquire new information in early AD. This review argues that the pattern of cognitive deficits contributing to the acquisition impairment in early AD patients may be readily interpreted within the context of a working memory model. Isolating the component processes of working memory that underlie the acquisition deficit in early AD patients will aid in the design of clinical applications that are focussed at enhancing the ability to acquire new information in everyday life.  相似文献

We tested whether individual differences in a component of early conscience mediated relations between parental discipline and externalizing behavior problems in 238 3.5-year-olds. Parents contributed assessments of discipline practices and child moral regulation. Observations of children's behavioral restraint supplemented parental reports. Parents and teachers reported on child externalizing symptoms. Parental induction, warm responsiveness, and less frequent use of physical punishment generally were associated with higher levels of moral regulation and fewer externalizing problems. Moreover, moral regulation partially mediated relationships between discipline and externalizing symptoms, with the clearest case of mediation involving induction. However, relationships were found for boys only. Results support a mediation model wherein inductive and physical discipline may influence the expression of boys' externalizing behavior through effects on conscience. Finally, results suggest that different developmental processes may be associated with early externalizing problems in boys and girls, and confirm that fathers' reports contribute to our understanding of the origins of child externalizing problems.  相似文献

We review the recently published report by the Committee on the Prevention of Reading Difficulties in Young Children from a behavior analytic perspective. The authors prescribe what children should learn to be successful readers based on the correlates of reading and the developmental progression of reading errors. The report offers no discussion of theoretical models that can be used by teachers and parents to reform reading instruction or specific procedures that have been shown to be effective at promoting various reading skills. We discuss these omissions in terms of the level of research included in the review, the authors' structural approach to synthesizing this research, and the constructivist orientation common to many early childhood educators. The paper concludes by identifying models and strategies from the behavior analysis literature that can be used to guide instruction and offers a modest suggestion for future reviews of reading research.  相似文献

Over the past decade, increasing attention has been paid to gender‐related consumption behaviour. However, a relative gap in our knowledge still exists when it comes to understanding the changes that occur as a result of motherhood and how this may influence their interactions in the retail environment. The purpose of this article is to explore stay‐at‐home mothers’ experiences in the servicescape to gain a better understanding of how they associate with servicescapes during this transitional period, how they use retail space to suit their needs, and how they use retail space to negotiate their role as a stay‐at‐home mother. Five stay‐at‐home mothers with children younger than 5 years were provided with disposable cameras and asked to photograph servicescapes that they visited regularly. Over a 1‐year period, they were interviewed several times, and photo‐elicitation techniques were used throughout the interviewing process. The results of this study suggest that when consumers undergo role or identity changes, certain places can be used to smooth this process. Not only can the retail environment be used as a coping mechanism for stay‐at‐home mothers, it can also be viewed as a “second place” as opposed to a “third place”, thus enabling isolated consumers to feel connected with the outside world. Last, this study highlights the temporal dimensions of place. Throughout one's lifetime, one will form attachments to and patronise different places, which will evolve and change as individuals, accordingly, take on different roles and identities.
