Reports of exaggerated anxiety and physiological hyperreactivity to social-evaluative situations are characteristic of childhood
social phobia (SP). However, laboratory research on subjective, autonomic and endocrine functioning in childhood SP is scarce,
inconsistent and limited by small sample sizes, limited breadth of measurements, and the use of non-standardized stressor
tasks. We exposed 8–12-year-old children with DSM-IV SP (n = 41) and matched healthy control children (HC; n = 40) to the Trier Social Stress Test for Children (TSST-C) while measuring subjective anxiety, heart rate (HR) and salivary
alpha-amylase (sAA) as well as salivary cortisol. The SP children showed heightened reactivity to the TSST-C on subjective
anxiety compared to the HC children but not a heightened reactivity in HR, sAA or cortisol. However, the SP children showed
chronically elevated HR levels throughout the whole laboratory session. Whereas subjective anxiety seems to respond specifically
to social-evaluative stress in childhood SP, HR levels may be chronically elevated suggesting a more generalized autonomic
hyperreactivity. 相似文献

Differentiating between early-onset bipolar disorder (BD) and attention-deficit/hyperactivity disorder (ADHD) can be difficult. Memory problems are commonly reported in BD, and forgetfulness is among the diagnostic criteria for ADHD. We compared children and adolescents with BD (n?=?23), ADHD combined type (ADHD-C; n?=?26), BD?+?ADHD-C (n?=?15), and 68 healthy controls on memory tests (Digit span, Children's Verbal Learning Test-II). Further analyses were performed on subgroups of BD (BD-I, BD-II/BD-NOS, with and without previous psychotic symptoms). All clinical groups demonstrated some problems with free recall, but the BD subgroup with a history of psychotic symptoms had a more pervasive problem that also included recognition and semantic clustering. The ADHD-C groups demonstrated the lowest performance on working memory. These data suggest that children and adolescents with BD and previously psychotic symptoms may have inefficient encoding of verbal material, whereas memory problems in ADHD-C appear more characterized by impaired free recall. 相似文献

Many studies are concerned with the bivariate relationships between Openness, fluid intelligence (Gf), and crystallized intelligence (Gc). Results suggest an influence of Gf and Openness on Gc. However, the overlap between Gf and Openness is rarely controlled for. Moreover, interaction effects or longitudinal influences are also often neglected. The present two studies aimed to elucidate exactly these interactions and longitudinal influences. Besides a main effect of Gf on Gc, Study 1 (N = 180) revealed an interaction effect between Openness and Gf. Study 2 utilized longitudinal data (N = 172) and identified an effect of Openness on the development of Gf. Gf and Openness predicted Gc 6 years later. A model integrating the results and providing a theoretical framework and outlook is proposed. 相似文献

Illusions of personal authorship can arise when causation for an event is ambiguous, but people mentally represent an anticipated outcome and then observe a corresponding match in reality. When people do not maintain such high-level outcome representations and focus instead on low-level behavioral representations of concrete actions, illusions of personal authorship can be reduced. One condition that yields specific action plans and thereby moves focus from high-level outcomes to low-level actions is the generation of counterfactual thoughts. Hence, in the present research we tested whether thinking counterfactually can reduce illusory authorship. In line with predictions, generating behavior-regulating counterfactuals reduced susceptibility to the illusion (Study 1). Importantly, this only occurred when people expected to re-encounter the situation to which the counterfactuals applied (Study 2). These findings extend existing research on the boundary conditions of illusory experiences of personal authorship and might hint at a relationship between the illusion and behavior regulation. 相似文献

This collection of papers is the result of research presented at the 2010 meeting of the American Academy of Religion in Atlanta, Georgia, sponsored by the Comparative Studies of Religion section. The set of papers resulting from the panel, Politics of Faith in Asia: Local and Global Perspectives of Christianity in Asia, presents findings from a diverse array of cultural areas and historical contexts across the Asian continent. All of these are connected by a focus on the intersection of Christianity and the political organisation in Asian societies. Although each paper focuses primarily on the continued encounter of Protestant, Evangelical Christianity and local religions, the definition and scope of the political milieu differ considerably. Moving from local communities in a small Indian town, through the growing global connections of religious groups in the Philippines, to the global and national politics of South Korea, the set addresses a multitude of political levels, be they governmental or the processes of everyday interactions. 相似文献

A one-year longitudinal study with 324 German third and fourth graders was conducted in order to find out whether a preference for violent electronic games socializes children to become more aggressive or whether aggressive individuals tend to select this type of game. Cross-lagged panel analyses suggest that children who were rated as openly aggressive at Time 1 intensified their preference for violent electronic games over time. We determined that it could be ruled out that this selection effect was due to a number of underlying variables ranging from ecological variables (neighborhood) to family variables (migration status, older brother) and child variables (gender, self-esteem, level of achievement). Discussion focuses on the emerging preference for violent electronic games among children. 相似文献

Social learning is taxonomically widespread and can provide distinct behavioural advantages, such as in finding food or avoiding predators more efficiently. Although extensively studied in bony fishes, no such empirical evidence exists for cartilaginous fishes. Our aim in this study was to experimentally investigate the social learning capabilities of juvenile lemon sharks, Negaprion brevirostris. We designed a novel food task, where sharks were required to enter a start zone and subsequently make physical contact with a target in order to receive a food reward. Naive sharks were then able to interact with and observe (a) pre-trained sharks, that is, ‘demonstrators’, or (b) sharks with no previous experience, that is, ‘sham demonstrators’. On completion, observer sharks were then isolated and tested individually in a similar task. During the exposure phase observers paired with ‘demonstrator’ sharks performed a greater number of task-related behaviours and made significantly more transitions from the start zone to the target, than observers paired with ‘sham demonstrators’. When tested in isolation, observers previously paired with ‘demonstrator’ sharks completed a greater number of trials and made contact with the target significantly more often than observers previously paired with ‘sham demonstrators’. Such experience also tended to result in faster overall task performance. These results indicate that juvenile lemon sharks, like numerous other animals, are capable of using socially derived information to learn about novel features in their environment. The results likely have important implications for behavioural processes, ecotourism and fisheries. 相似文献
