A modified proactive interference paradigm was developed to investigate encoding and memory processes in preschool-age children. The buildup and release from proactive interference in preschool-age children parallels that of adults and of mentally retarded persons, indicating that very young children and older people may use many of the same encoding dimensions. 相似文献

Developmental stuttering is known to be associated with aberrant brain activity, but there is no evidence that this knowledge has benefited stuttering treatment. This study investigated whether brain activity could predict progress during stuttering treatment for 21 dextral adults who stutter (AWS). They received one of two treatment programs that included periodic H215O PET scanning (during oral reading, monologue, and eyes-closed rest conditions). All participants successfully completed an initial treatment phase and then entered a phase designed to transfer treatment gains; 9/21 failed to complete this latter phase. The 12 pass and 9 fail participants were similar on speech and neural system variables before treatment, and similar in speech performance after the initial phase of their treatment. At the end of the initial treatment phase, however, decreased activation within a single region, L. putamen, in all 3 scanning conditions was highly predictive of successful treatment progress. 相似文献

The primary objective of this study was to reevaluate the well-established result that preschoolers' performance on executive function tasks are positively associated with their performance on academic achievement tests. The current study replicated the previously established concurrent associations between children's performance on EF tasks and academic achievement tests. Specifically, children's performance on measures of inhibitory and motor control were positively associated with their performance on tests of reading, writing, and mathematics achievement (rs?=?.2?.5); moreover, although diminished in magnitude, most of these associations held up even after including an earlier measure of academic achievement as a covariate (rs?=?.1?.3). However, the application of an alternative analytic method, fixed effects analysis, a method that capitalizes on repeated measures data to control for all time stable measured and unmeasured covariates, rendered the apparent positive associations between executive function and academic achievement nonsignificant (rs?=?.0?.1). Taken together, these results suggest that the well-replicated association between executive function abilities and academic achievement may be spurious. Results are discussed with respect to the importance of utilizing analytic methods and research designs that facilitate strong causal inferences between executive function and academic achievement in early childhood, as well as the limitations of making curriculum development recommendations and/or public policy decisions based on studies that have failed to do so. 相似文献

Pacific peoples represent one of the fastest growing population subgroups in New Zealand and suffer disproportionately from diabetes, obesity, and other diseases. There is little research on the predictors of behavioral problems in Pacific children or the role that cultural variables play in shaping the unique environments in which child development occurs This study aims to examine the: (1) prevalence of behavior problems at 2, 4, and 6 years-of-age among Pacific children, and (2) relationships between maternal, cultural, and socio-demographic factors and behavioral problems. Data were gathered from the Pacific Islands Families Study. Maternal reports of child behavior were obtained using the Child Behavior Checklist for over 1000 Pacific children. The prevalence of clinical internalizing problems at ages 2, 4, and 6 years was 16.8, 22 and 8.5%, and clinical externalizing was 6.7, 10.7, and 14.6% respectively. Significant risk factors associated with clinical internalizing were maternal depression, maternal smoking, intimate partner violence, and having a single mother. Significant risk factors for clinical externalizing were harsh parenting, maternal depression, having a New Zealand born mother, and low household income. Across dimensions, a protective factor was found for children with mothers who described themselves as strongly aligned with Pacific traditions. These findings contribute to the limited longitudinal data specific to children from different ethnic groups and demonstrate the importance of cultural factors in developmental outcomes. 相似文献

Internalization of societal standards of physical attractiveness (i.e., internalization of the thin ideal for women and internalization of the mesomorphic ideal for men) is a widely studied and robust risk factor for body dissatisfaction and maladaptive body change behaviors. Substantial empirical research supports internalization as both a mediator and a moderator of the relation between societal influences and body dissatisfaction. In this paper, a primer on mediation and moderation is followed by a review of literature and discussion of the extent to which internalization can theoretically fulfill the roles of both mediation and moderation. The literature review revealed a stark contrast in research design (experimental versus non-experimental design) when alternate conceptualizations of internalization are adopted. A meta-theoretical, moderated mediation model is presented. This model integrates previous research and can inform future empirical and clinical endeavors. 相似文献

We assessed the impact of adolescent nonsuicidal self-injury (NSSI) on parents in two studies. In Study 1, 16 Australian parents of adolescents with a history of nonsuicidal self-injury responded to open-ended questions about their child’s nonsuicidal self-injury. Data from 10 of the adolescents were matched with parents’ responses regarding the nature and extent of nonsuicidal self-injury, revealing that parents underestimated the frequency of nonsuicidal self-injury, the age of onset, and the likelihood their child would continue to self-injure. In Study 2, 22 American parents of adolescents with a history of nonsuicidal self-injury participated in interviews about their experiences. Parents in both studies reported changes in the parent–adolescent relationship after self-injury, which posed challenges to the family unit. When professional help had been sought, experiences were largely negative. Results support further investigation into family-based interventions to equip parents with tools to better relate to, and communicate with, their adolescent following self-injury. Results also suggest that mental-health professionals and general practitioners may require further training for nonsuicidal self-injury. 相似文献

Aggression and peer victimization as predictors of self‐reported behavioral and emotional adjustment
The relative contributions of aggression and victimization to the prediction of self‐reported emotional and behavioral difficulties over and above self‐reported prior problems were investigated in a 1‐year longitudinal study. Fourth‐, fifth‐, and sixth‐graders (N = 471) completed peer nominations of aggression and victimization as well as self‐report measures of social, behavioral, and emotional problems at baseline and at 1‐year follow‐up. Peer aggression added to the prediction of externalizing problems, specifically, self‐report of aggression and delinquency. In contrast, victimization by peers contributed to self‐reported unpopularity but not depression. Victimization among girls was also predictive of subsequent self‐reported delinquency. Theoretical and practical implications of the findings, as well as future directions for research, are discussed. Aggr. Behav. 26:345–358, 2000. © 2000 Wiley‐Liss, Inc. 相似文献

Exposure to peer aggression is a major risk factor for the development of aggressive behavior in childhood and adolescence. Furthermore, peer aggression has the propensity to spread and affect individuals who were not exposed to the original source of aggression. The aim of this paper is to demonstrate that peer aggression is in many regards similar to a contagious disease. By presenting a program of research based on longitudinal and multilevel studies, we provide evidence for the contagious quality of aggressive behavior, show that individuals vary in their susceptibility to peer aggression, and describe group‐level characteristics that moderate the influence of peer aggression. We discuss mechanisms that may explain how individuals catch aggressive behavior from their peers and how the effects on the development of individuals' aggressive behavior unfold over time. Further, we examine processes that may increase the risk of being exposed to peers' aggressive behavior. We conclude with discussing implications for future studies on the contagious nature of peer aggression. 相似文献
