Working memory (WM) skills are closely associated with learning progress in key areas such as reading and mathematics across childhood. As yet, however, little is known about how the brain systems underpinning WM develop over this critical developmental period. The current study investigated whether and how structural brain correlates of components of the working memory system change over development. Verbal and visuospatial short‐term and working memory were assessed in 153 children between 5.58 and 15.92 years, and latent components of the working memory system were derived. Fractional anisotropy and cortical thickness maps were derived from T1‐weighted and diffusion‐weighted MRI and processed using eigenanatomy decomposition. There was a greater involvement of the corpus callosum and posterior temporal white matter in younger children for performance associated with the executive part of the working memory system. For older children, this was more closely linked with the thickness of the occipitotemporal cortex. These findings suggest that increasing specialization leads to shifts in the contribution of neural substrates over childhood, moving from an early dependence on a distributed system supported by long‐range connections to later reliance on specialized local circuitry. Our findings demonstrate that despite the component factor structure being stable across childhood, the underlying brain systems supporting working memory change. Taking the age of the child into account, and not just their overall score, is likely to be critical for understanding the nature of the limitations on their working memory capacity. 相似文献

The syntax and semantics of human language can illuminate many individual psychological differences and important dimensions of social interaction. Accordingly, psychological and psycholinguistic research has begun incorporating sophisticated representations of semantic content to better understand the connection between word choice and psychological processes. In this work we introduce ConversAtion level Syntax SImilarity Metric (CASSIM), a novel method for calculating conversation-level syntax similarity. CASSIM estimates the syntax similarity between conversations by automatically generating syntactical representations of the sentences in conversation, estimating the structural differences between them, and calculating an optimized estimate of the conversation-level syntax similarity. After introducing and explaining this method, we report results from two method validation experiments (Study 1) and conduct a series of analyses with CASSIM to investigate syntax accommodation in social media discourse (Study 2). We run the same experiments using two well-known existing syntactic metrics, LSM and Coh-Metrix, and compare their results to CASSIM. Overall, our results indicate that CASSIM is able to reliably measure syntax similarity and to provide robust evidence of syntax accommodation within social media discourse. 相似文献

ABSTRACTReligious beliefs and practices are believed to foster well-being across the life course. This study examines whether religious practice, spiritual development, and existential certainty are positively linked to well-being in grandparents (N = 2,503) and whether these factors buffer grandparents from risks associated with raising grandchildren and adjusting to changing roles. Data were collected from individuals attending Protestant churches. Spiritual development and existential certainty were positively associated with well-being. We found no evidence for buffering effects of religious practice on grandparent well-being. Grandparents raising grandchildren reported more challenges in adjusting to changes in roles compared to their peers. 相似文献

Although there is substantial functional behavioral assessment (FBA) literature suggesting that function-based interventions are effective for improving problem behavior, only a limited number of studies have examined the effectiveness of function-based antecedent versus consequent interventions. Additionally, although there has been a recent increase in the number of studies conducted in the K–12 school setting, only a limited number of studies have included children in the preschool setting. The present study extends existing literature by examining the effectiveness of function-based antecedent versus consequent interventions for reducing problem behavior and increasing appropriately engaged behavior for preschool children without cognitive disabilities. Following an FBA of 4 children, the effectiveness of a function-based antecedent (i.e., noncontingent reinforcement [NCR]) was compared with a function-based consequent (i.e., differential reinforcement of alternative behavior [DRA]) intervention using an alternating treatments design. Results indicated that both function-based NCR and DRA were effective for decreasing problem behavior and increasing appropriately engaged behavior, with function-based NCR being more effective than DRA for 2 of 4 participants. 相似文献

The current study examined how dimensions of masculinity and femininity were expressed for sexual minorities. Cluster analysis was used to determine the number of latent classes for conformity to masculine and feminine norms for sexual minorities. A four-class solution was the best fit to the data. Cluster 1 (labeled Relating to others through equality and caring, n = 41) was characterized by low dominance and power over women and high involvement with kids and have nice relationships norms. Cluster 2 (labeled Relating to others through avoidance and misogyny, n = 38) was characterized by low risk-taking and have nice relationships and high power over women and disdain for homosexuality. Cluster 3 (labeled Relating to others through power, n = 34) was characterized by high winning, pursuit of status, and appearance and low modesty. Cluster 4 (labeled Relating to others through sex, n = 27) was characterized by low involvement in romantic relationships and sexual fidelity while endorsing high playboy attitudes. Results indicate that conforming to gender norms tends to follow categories of interpersonal beliefs and behaviors rather than being based in gender identity or sexual orientation. Implications of the results for future research and clinical practice are examined. 相似文献

When a solid crosses the glass transition, viscous flow sets in and the glass transforms into a supercooled liquid. The glass transition temperature exhibits a heating rate dependence which was previously observed to follow a Vogel–Fulcher–Tammann (VFT) equation. Here we report on a change in the heating rate dependence of the glass transition, determined by the distinct increase in the specific heat capacity, of a metallic glass. We combine standard techniques such as differential scanning calorimetry with recently developed ohmic heating techniques in order to cover seven orders of magnitude in heating rate. Contrary to previous reports, our results show that the change of the glass transition temperature cannot be described by a single VFT equation. Instead we find two distinct regimes which independently follow a VFT expression. 相似文献

Kant wants to show that freedom is possible in the face of natural necessity. Transcendental idealism is his solution, which locates freedom outside of nature. I accept that this makes freedom possible, but object that it precludes the recognition of other rational agents. In making this case, I trace some of the history of Kant’s thoughts on freedom. In several of his earlier works, he argues that we are aware of our own activity. He later abandons this approach, as he worries that any awareness of our activity involves access to the noumenal, and thereby conflicts with the epistemic limits of transcendental idealism. In its place, from the second Critique onwards, Kant argues that we are conscious of the moral law, which tells me that I ought to do something, thus revealing that I can. This is the only proof of freedom consistent with transcendental idealism, but I argue that such an exclusively first-personal approach precludes the (third-personal) recognition of other rational agents. I conclude that transcendental idealism thus fails to provide an adequate account of freedom. In its place, I sketch an alternative picture of how freedom is possible, one that locates freedom within, rather than outside of nature. 相似文献

The platinum mining sector in South Africa presents a significant context for the study of work engagement, given the major changes and turmoil experienced by employees in this sector. The aim of this study was to investigate the effects of task and relational factors on work engagement in the platinum mining industry in South Africa. A stratified random sample (N = 564) comprising employees in a platinum mining organisation in South Africa was surveyed (females = 35.1%, blacks = 51.6%, middle managers = 40.8%). The employees completed a biographical questionnaire and several other measures: the Engagement Scale, Supervisory Support Scale, Social Support Scale and Job Diagnostic Survey. The results supported a reliable three-factor structure (consisting of autonomy support, competence support, and relatedness support) for the Supervisory Support Scale. The structural model confirmed that task characteristics (comprising task significance and task identity) were strongly related to work engagement. Supervisor support and co-worker support showed a positive relationship with work engagement, albeit to a lesser extent. 相似文献

This study explores men’s experiences in compensated dating (CD), particularly their process of becoming a client of CD in Hong Kong. By drawing on 30 individual interviews with male clients, cyber-ethnography of a major CD on-line forum, informal conversations with CD participants, off-line participant observations, and the sparse literature available on this under-examined social phenomenon, we also analyze men’s subjective understandings of being a client, of CD providers, and of CD itself, which influence men’s CD experiences and condom use behavior. Finally, this study sheds light on the contemporary issues of masculinity and sexuality in Hong Kong. 相似文献

Our findings draw attention to the interpersonal communication function of a relatively unexplored dimension of emotions—the level of social engagement versus disengagement. In four experiments, regardless of valence and target group gender, observers infer greater relational well-being (more cohesiveness and less conflict) between group members from socially engaging (sadness and appreciation) versus disengaging (anger and pride) emotion expressions. Supporting our argument that social (dis)engagement is a critical dimension communicated by these emotions, we demonstrate (1) that inferences about group members' self-interest mediate the effect of socially engaging emotions on cohesiveness and (2) that the influence of socially disengaging emotion expressions on inferences of conflict is attenuated when groups have collectivistic norms (i.e., members value a high level of social engagement). Furthermore, we show an important downstream consequence of these inferences of relational well-being: Groups that seem less cohesive because of their members' proud (versus appreciative) expressions are also expected to have worse task performance. 相似文献
