The purpose of the study was to analyze the physical activity and the determinants of sedentary behavior in 1,268 Brazilian adolescents (638 girls, 630 boys) between the ages of 15 and 18 years, randomly selected from a relatively underdeveloped region. Data were collected from a community-based survey in the city of Jo?o Pessoa, Paraiba, Brazil. Information related to physical activity was derived on the short version of the International Physical Activity Questionnaire. The prevalence of sedentary behavior was 28.2% for girls and 19.1% for boys, whilst 28.9% of the girls and 36.7% of the boys showed high physical activity. The sedentary behavior varied by sociodemographic and environmental determinants studied. Parents' education, socioeconomic status, school's characteristics, transport to school, paid work, smoking, alcohol use, and BMI scores were significantly related to sedentary behavior for boys and girls. 相似文献

Attention-deficit/hyperactivity disorder (ADHD) affects between 2 and 8?% of college students. ADHD is associated with impaired academic, psychological, and social functioning, and with a wide array of negative outcomes including lower GPAs, graduation rates, and self-reported quality of life. The college environment often brings decreased external structure and increased availability of immediate rewards, presenting added demands for behavioral self-regulation—an area in which students with ADHD are already vulnerable. Despite the significant impact of ADHD in college and the unique challenges presented by the college context, virtually no treatment development research has been conducted with this population. In order to provide a framework to guide intervention development, this comprehensive review integrates research from three key domains that inform treatment for college students with ADHD: (1) functional impairment associated with ADHD among college students, (2) etiology of ADHD and the developmental context for ADHD among emerging adults (age 18–24), and (3) treatment outcome research for ADHD among adolescents and adults. A detailed set of proposed treatment targets and intervention principles are identified, and key challenges associated with treatment development in this population are discussed. 相似文献

Affiliative stimuli are pleasant and highly biologically relevant. Affiliative cues are thought to elicit a prosocial predisposition. Here affiliative and neutral pictures were exposed prior to a reaction time task which consisted in responding to a visual target. Half the participants responded with finger-flexion, a movement frequently involved in prosocial activities. The other half responded with finger extension, a less prosocially compatible movement. Results showed that under the exposure to affiliative pictures, as compared to neutral ones, participants who used finger flexion were faster, while those using finger extension were slower. Performance benefits to the task, when flexing the finger, together with performance costs, when extending it, indicate the relevance of movement compatibility to the context. These findings put forward a possible link between affiliative primers and motor preparation to facilitate a repertoire of movements related to prosocial predispositions including finger flexion. 相似文献

We explored the neuropsychological and neuromorphometrical differences between probable Alzheimer's disease patients showing a good or a bad response to nine months treatment with donepezil. Before treatment, the neuropsychological profile of the two patient groups was perfectly matched. By the ninth month after treatment, the BAD-responders showed a decline of the MMSE score together with a progressive impairment of executive functions. A voxel-based morphometry investigation (VBM), at the time of the second neuropsychological assessment, showed that the BAD-responders had larger grey and white matter atrophies involving the substantia innominata of Meynert bilaterally, the ventral part of caudate nuclei and the left uncinate fasciculus, brain areas belonging to the cholinergic pathways. A more widespread degeneration of the central cholinergic pathways may explain the lack of donepezil efficacy in those patients not responding to a treatment that operates on the grounds that some degree of endogeneous release of acetylcholine is still available. 相似文献

This article reports on some findings of a small research project that examined the role of meditation in enhancing the relational lives of children, in particular, their relationship with God. It begins by discussing the literature on relevant research studies that investigate different aspects of meditation. The research method in the project was a case study that involved one Catholic primary school in the Melbourne Archdiocese. Different data collecting strategies were utilised, and this article presents and discusses the analysis and findings from one data source – the analysis and interpretation of a drawing activity which was designed to follow one of the weekly meditation exercises that had been observed by the researchers. Finally, the implications of the findings for education and, in particular, religious education are presented. 相似文献

The Stroop effect is one of the most famous examples of interference in human perception. The present study demonstrates that a position Stroop paradigm, comparable to the classical color-word interference paradigm, resulted in the same pattern of interference for the spatial dimension; however, the interference was significantly weaker. By exchanging the original oral response for a manual response in the spatial paradigm, we showed that the verbal component is crucial for the Stroop effect: Manual responses lead to a disappearance of the interference effect. Moreover, with manual responses word position was recognized at the same speed for the baseline condition and for words that were incongruent as well as congruent with the spatial position. The results indicate (1) that the Stoop effect depends heavily on verbal components and (2) that differing processing speeds between reading and position recognition do not serve as a proper explanation for the effect. In addition, the provided paradigm plausibly transfers the classical color-word interference to the spatial dimension. 相似文献

In the primate brain, sensory information is processed along two partially segregated cortical streams: the ventral stream, mainly coding for objects' shape and identity, and the dorsal stream, mainly coding for objects' quantitative information (including size, number, and spatial position). Neurophysiological measures indicate that such functional segregation is present early on in infancy, and that the two streams follow independent maturational trajectories during childhood. Here we collected, in a large sample of young children and adults, behavioural measures on an extensive set of functions typically associated with either the dorsal or the ventral stream. We then used a correlational approach to investigate the presence of inter‐individual variability resulting in clustering of functions. Results show that dorsal‐ and ventral‐related functions follow two uncorrelated developmental trajectories. Moreover, within each stream, some functions show age‐independent correlations: finger gnosis, non‐symbolic numerical abilities and spatial abilities within the dorsal stream, and object and face recognition abilities within the ventral stream. This pattern of clear within‐stream cross‐task correlation seems to be lost in adults, with two notable exceptions: performance in face and object recognition on one side, and in symbolic and non‐symbolic comparison on the other, remain correlated, pointing to distinct shape recognition and quantity comparison systems. 相似文献

RESUMENTanto en la perspectiva diferencial como en el análisis cognitivo o más ligado a la “psicología general”, el problema de la creatividad ha preocupado a los psicólogos durante décadas. Bajo la etiqueta general de “creatividad” se sitúan algunos de los interrogantes más apasionantes que se pueden estudiar en psicología: Definición de creatividad, procesos implicados en la creatividad, la existencia de diferencias individuales. En este artículo se hace una revisión sumaria de las distintas teorías del proceso creador de Bus y Mansfield, que han intentado dar cuenta de los interrogantes antes mencionados. 相似文献
