Studies on gene–environment interactions suggest that some individuals may be more susceptible to life adversities than others due to their genetic profile. This study assesses whether or not children with an extra X chromosome are more vulnerable to the negative impact of early life stress on cognitive functioning than typically-developing children.
A total of 50 children with an extra X chromosome and 103 non-clinical controls aged 9 to 18 years participated in the study. Cognitive functioning in domains of language, social cognition and executive functioning were assessed. Early life stress was measured with the Questionnaire of Life Events. High levels of early life stress were found to be associated with compromised executive functioning in the areas of mental flexibility and inhibitory control, irrespective of group membership. In contrast, the children with an extra X chromosome were found to be disproportionally vulnerable to deficits in social cognition on top of executive dysfunction, as compared to typically-developing children. Within the extra X group the number of negative life events is significantly correlated with more problems in inhibition, mental flexibility and social cognition. It is concluded that children with an extra X chromosome are vulnerable to adverse life events, with social cognition being particularly impacted in addition to the negative effects on executive functioning. The findings that developmental outcome is codependent on early environmental factors in genetically vulnerable children also underscores opportunities for training and support to positively influence the course of development. 相似文献
Children with 22q11.2 deletion syndrome (22q11DS; velo-cardio-facial-syndrome) are at risk for the developmental disorders, attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD). In this study, the relation between executive functioning (EF) and the severity of ADHD and ASD symptoms is examined, since EF is known to be important in relation to emotional and behavioral problems. The participants consist of 58 children (38 females) with a mean age of 13.5 years (SD 2.6). Standardized assessment was used to evaluate the severity of ASD and ADHD symptomatology. The major aspects of EF, i.e., cognitive flexibility, inhibition, sustained attention, distractibility, working memory and reaction speed, were evaluated. The profile of EF in 22q11DS was found to be characterized by weaker performance compared to the norms on all subdomains of EF. Poor cognitive flexibility and inhibition, as well as high distractibility, were found to be related to more severe ASD symptoms, while poor quality of sustained attention and high distractibility were found to be related to more severe ADHD symptoms. It is concluded that children with 22q11DS experience impairments in EF, and that the degree of impairment on specific EF subdomains is related to the severity of ASD and/or ADHD symptomatology. These results may help in defining the mediating role of neurocognitive dysfunctions in the development of social and behavioral problems in 22q11DS. 相似文献
Multicultural counseling approaches variously focus on the counseling relationship. Relatively few discuss clinical techniques and strategies to any significant extent. This article explores enhancing multicultural counseling by offering an array of techniques and strategies based on addressing oppression and increasing psychological freedom. Techniques offered seek to internally free a person cognitively, affectively, and systemically using the Precursors Model of Change (Hanna, 2002). The goal is to help set a person free from oppressive, discriminatory systems and individuals. 相似文献
This study tested the influence of orientation priming on grasping decisions. Two groups of 20 healthy participants had to
select a preferred grasping orientation (horizontal, vertical) based on drawings of everyday objects, geometric blocks or
object names. Three priming conditions were used: congruent, incongruent and neutral. The facilitating effects of priming
were observed in the grasping decision task for drawings of objects and blocks but not object names. The visual information
about congruent orientation in the prime quickened participants’ responses but had no effect on response accuracy. The results
are discussed in the context of the hypothesis that an object automatically potentiates grasping associated with it, and that
the on-line visual information is necessary for grasping potentiation to occur. The possibility that the most frequent orientation
of familiar objects might be included in object-action representation is also discussed. 相似文献
In this article, we review both theoretical and empirical advancements in retirement adjustment research. After reviewing and integrating current theories about retirement adjustment, we propose a resource-based dynamic perspective to apply to the understanding of retirement adjustment. We then review empirical findings that are associated with the key research questions in this literature: (a) What is the general impact of retirement on the individual? and (b) What are the factors that influence retirement adjustment quality? We also highlight important future research directions that may be fruitful for psychologists to pursue in this area. 相似文献
This article explores the poetic and political-theological nexus of power, violence and sovereignty in Meir Wieseltier's work. No poet seems to have inserted himself quite so powerfully into the narrow crack between the authority of the political sovereign and that of the divine sovereign, warning against the dangerous link between the theological and the political in Israel's messianic discourse. Wieseltier seems to draw inspiration from the theological-political sovereignty which relies on “an act of exception”, then to perform it poetically (“an exceptional verb”) to found his sovereignty and authority. Wieseltier's poetry arises from the divine music of catastrophe, based on a great intimacy with the ancient sources. It includes musical syntactic structures, like the mishnaic catalogue syntax, or the apocalyptic language of liturgical poetry in the prayers for the High Holy days with their outrageous “music of curses”. 相似文献
The aim of this study was to further refine the cognitive phenotype of attention-deficit/hyperactivity disorder (ADHD), with respect to the ability to sustain attention and executive functioning. Participants were 34 boys with ADHD (combined type) and 28 normal controls. The groups were closely matched for age and IQ. All participants were 12 years of age. Both groups performed a computerized sustained attention task and a response interference task. Measures related to speed, accuracy, and time on task were collected. We found that children with ADHD performed slower, less accurately, more impulsively, and with less stability than controls. Both groups produced more errors with increasing time on task, reflecting reduced vigilance. Importantly, no interaction with time on task was found. The overall pattern of results suggests that measures related to accuracy are more informative than measures related to speed of responding in refining the cognitive phenotype of ADHD. 相似文献
Learning skills, social intelligence, and self-concept were related to each other and to bully-victim problems among fifth-grade children (79 boys and 62 girls, aged 11-12 years). In addition to exploring connections between single variables, a person-oriented approach was applied in order to analyze children's value patterns with respect to learning skills, self-concept, and social intelligence, and how these value patterns are related to bully-victim problems. Social intelligence was found to be positively correlated with learning skills, but negatively related to victimization. Bullying was positively correlated with self-concept scores. However, this was true only of boys. According to cross-tabulations, there were significantly more bullies among children with learning difficulties (LD) than would have been expected by chance. Victimization, on the other hand, was not related to LD. LD children's proposed victim status was in some degree supported by cluster analysis: a group of LD children emerged, who not only scored high on bullying, but also tended to be victimized by others. In addition, two groups of bullies appeared: one whose members could be interpreted as socially unskilled and another as socially skilled. This finding is in line with recent theoretical reasoning, which calls into question the idea of bullies as a unified group, lacking in social skills. 相似文献
