We aim to analyze the effects of an 8-month physical activity intervention on cardiorespiratory fitness, body mass index (BMI), and vigilance performance in an adult obese population. We conducted an 8-month physical activity intervention based on dance and rhythmic activities. The weekly frequency was 2 sessions of 1 hr per day. Training sessions were divided into 3 phases: a 10-min warm-up, 40 min of dance and rhythmic activities, and 10 min to cool-down. To assess cardiorespiratory fitness, participants performed a modified version of the 6-min walk test from the Senior Fitness Test battery (Larsson & Mattsson, 2001; Rikli & Jones, 1999). Vigilance performance was measured by means of the psychomotor vigilance task (PVT). Two measurements were performed immediately before and after the intervention. The results revealed that participants improved their cardiorespiratory fitness, BMI, and vigilance performance after the intervention. All in all, findings contribute new empirical evidence to the field that investigates the benefits of physical activity intervention on cognitive processes in obese population. 相似文献

Fostering oral communication competences constitutes a primary goal of higher education. However, research on the acquisition process is sparse, especially when the role of learning-related emotions is considered. Based on control-value theory, this study therefore investigated the interplay between learning-related boredom and enjoyment and the build-up of moderation competence throughout an university course to foster oral competences. A longitudinal quasi-experimental study with two teaching conditions was conducted. About 160 students were assigned either to a control group (CG: autonomy supportive teaching enriched with basic levels of competence support and relatedness support) or an experimental group (EG: autonomy supportive teaching enriched with high levels of competence support and relatedness support). Perceived moderation competence and emotions were assessed three times (T) by self-report: after completion of the course introduction (T1), half way (T2), and at the end of the course (T3). The students’ behavioral performance during a practical moderation exam was graded at T3. Path analyses revealed differential effects of enjoyment and boredom on students’ perceived moderation competence and their grades over time: an activating, learning-enhancing effect of enjoyment on moderation competence was demonstrated, especially if teachers supported students’ experience of autonomy, competence, and relatedness. Boredom, in contrast, had a detrimental effect on the behavioral performance in the practical moderation exam. 相似文献

Researchers have long questioned relationships among self-conceptions, “mental illness,” and stigma. This article looks at these issues through the lens of Obsessive-Compulsive Disorder (OCD), as minimal research has focused on the lived experience of OCD. We examine the impact of OCD on constructions of identity and the management/resistance of stigma. We do this through in-depth interviews with an untraditional Internet-based sample. We find respondents experience a crisis of self that leads them to a variety of strategies to deal with self-stigma, experienced stigma, and anticipated stigma. 相似文献

In this article, we examine the regulation of psychiatric patients becoming intoxicated from drinking excessive amounts of liquids at a large psychiatric asylum in Canada. We analyze how medical staff created a formalized diagnostic category and a specialized ward for its treatment. We consider the institutional context in which “water intoxication” was developed as a diagnostic category and we examine the impact of this diagnosis on the regulation of asylum patients. Finally, we discuss the patients’ opposition to treatment as well as the impact of “water intoxication” on their self-identity and institutional status. 相似文献

ResumenEl objetivo del presente trabajo es comparar la eficacia de dos tratamientos, Autoinstrucciones (AI) y Solución de Problemas (SP), en la reducción de la impulsividad infantil y la mejora del rendimiento escolar. Alumnos impulsivos (seleccionados a partir del MFF-20) de cuarto y quinto de EGB (n = 18) fueron asignados a una de las dos condiciones de tratamiento, de dieciocho sesiones, o a un grupo control. Los resultados indican una superior eficacia del tratamiento de SP, ya que las latencias sobre el test MFF-20 aumentaron (p <.01) Y además, tanto en latencias como en errores, diferían de los otros dos grupos al terminar el tratamiento (p <.01). En cuanto al rendimiento escolar, los efectos de ambos tratamientos han sido mínimos, aunque sugieren también cierta superioridad del SP. Estos resultados señalan la necesidad de analizar en los programas multicomponentes el grado de contribución de cada procedimiento a la reducción de la impulsividad, concretamente el componente AI no parece contribuir decisivamente a ello. 相似文献

Abstract Background In survival analysis, those who are alive are statistically coded as 1.0 while those who are dead are coded as 0.0. Since everyone who remains alive is given the same score, a person confined to bed with an irreversible coma is alive and is counted the same as someone who is active and asymtomatic. The Quality of Well-being (QWB) scale defines levels of wellness on the continuum between death and optimum function and integrates morbidity and mortality into the same number. This paper demonstrates the effect of including mortality in QWB estimates for male adults with HIV infection. Method This study involves follow-up of a cohort of 386 male adults participating in the San Diego HIV Neurobehavioral Research Center (HNRC). Patients were evaluated using the QWB at enrollment and at six month intervals. All patients were classified into three stages of HIV disease according to the Center for Disease Control (CDC) classification: CDC IV (symptomatic HIV disease), CDC II or III (asymptomatic infection) and uninfected male controls. Results QWB scores were calculated with and without mortality included for men in each CDC class who completed a one year (N = 148) or two year follow-up (N = 60). At each evaluation, there were significant differences among CDC classes and inclusion of deaths increased the variance accounted for by CDC class at each evaluation. Conclusions HIV infection has significant impacts upon both morbidity and mortality. Survival analysis captures only the mortality dimension, while quality adjusted survival analysis using the QWB includes both dimensions. We propose quality adjusted survival analysis as a more sensitive method for assessing outcome in HIV disease and other health conditions. 相似文献

The purpose of this investigation was to determine how confidence intervals (CIs) for pediatric neuropsychological norms vary as a function of sample size, and to determine optimal sample sizes for normative studies. First, the authors calculated 95% CIs for a set of published pediatric norms for four commonly used neuropsychological instruments. Second, 95% CIs were calculated for varying sample size (from n?=?5 to n?=?500). Results suggest that some pediatric norms have unacceptably wide CIs, and normative studies ought optimally to use 50 to 75 participants per cell. Smaller sample sizes may lead to overpathologizing results, while the cost of obtaining larger samples may not be justifiable. 相似文献

This article examines the formation process of spatial presence, which is conceived as a two-step process involving the construction of a mental model of the mediated environment, followed by the emergence of spatial presence. During both stages, cognitive processes and user traits are in effect. We present data derived from a pooled set of data of three studies using the same virtual environment. Structural equation modeling is used to confirm the proposed theoretical model. The results show that attention and the trait of visual spatial imagery are positive predictors of the mental model of the mediated environment. In the second step, the formation of spatial presence is governed by involvement, the suspension of disbelief, and the domain-specific interest, together with the mental model. 相似文献
