This study investigated psychological reactions of adolescents to a severe stress situation—the evacuation of the Sinai settlements. The research focused on emotional reactions of anxiety and anger to this stress situation. Two central problems were investigated: (a) The intensity of the emotional responses of anxiety and anger of the adolescents to the stress situation, before and after the evacuation, and (b) the impact of three intervening variables on these emotional reactions—cognitive perception of the political situation, family functioning, and personality characteristics. Data for this study were collected in a regional high school in Israel from 418 pupils in 9th through 12th grades. Seventy-eight of the pupils lived in the Yamit area. Measurements were obtained at three points in time: 6 weeks and 1 week before the evacuation and 2 months after it. The results supported the predicted trend that adolescents in the Yamit group before the evacuation would score higher on state anxiety and state anger than would those in the comparison group. Two months after the evacuation there was a significant drop in those scores. The trait measures remained stable in both groups and no significant differences were found between the two groups on these scores. Concerning the impact of the three intervening variables on the intensity of the state emotional responses, the results did not support any of the hypotheses. 相似文献

Content analysis of the sexual fantasies of 87 community college and university students revealed no significant sex differences in the content of sexual fantasies. Both men and women preferred traditional and facilitative fantasies. Because this study was explorative, however, further research is required to validate the suggested scale and replicate these results. 相似文献

Subjects (N = 217) rated the attractiveness of 56 general goals and then completed 3 theory-based tests of personality or motivation. Two goal factors—labeled Social-Economic Status and Competitive Achievement—seemed to reflect two broad domains of status-seeking motivation, and two other factors—labeled Growth Orientation and Interpersonal Security—pointed to separate domains of cooperative motivation. Thus, there was confirmation for the widespread assumption of two primary types of interpersonal motivation (solidarity and status) in our culture but also for important distinctions within each type. Canonical and direct correlations with the theoretically-grounded measures strongly supported that interpretation of the factors. Meaningful relationships between factors obtained from the questionnaire and the more rationally-based test scores indicated convergence in mappings of motivational space. 相似文献

ABSTRACT Past theory and research indicate that conditions of work can have lasting effects on job incumbents. R. A. Karasek and T. Theorell (1990), for example, proposed that workers’ feelings of mastery increase with levels of job demands and job control, and that these effects are mediated by the process of active learning. To test these propositions, 657 school teachers completed scales assessing job demands, control, active learning, and mastery on 2 occasions, 8 months apart. As hypothesized, job control predicted change in mastery, an effect that was mediated by active learning. Job demands had a weaker effect on change in mastery. The demands–mastery relationship was moderated by job control, so that under conditions of high control, but not low control, increasing job demands were associated with gains in mastery. The findings partially support R. A. Karasek and T. Theorell's (1990) predictions regarding the main, interactive, and mediated effects of job conditions on employee mastery. 相似文献

The weighted blanket (WB) is a modality used to self-comfort, rest, sleep, and decrease anxiety. This exploratory, pilot study investigates the safety and effectiveness of the standardized use of the 30-pound WB with 30 adults during an acute inpatient mental health hospitalization. Safety measures include blood pressure, pulse rate, and pulse oximetry monitoring, with and without the 30-pound WB. The State Trait Anxiety Inventory-10 (STAI-10), a self-rating 0–10 anxiety scale, and electrodermal activity (EDA) readings measure effectiveness for anxiety reduction. No statistical differences in vital signs indicate WB safety. The STAI-10 and self-ratings indicate 60% had a significant reduction in anxiety using the WB. EDA readings were inconclusive. 相似文献

The aim of this study was to identify the cascade of effects leading from alterations in force generation around the ankle joint to increased plantar pressures under the forefoot. Gait analysis including plantar pressure measurement was performed at an individually preferred and a standardized, imposed gait velocity in diabetic subjects with polyneuropathy (n = 94), without polyneuropathy (n = 39) and healthy elderly (n = 19). The plantar flexion moment at 40% of the stance phase was negatively correlated with the displacement rate of center of pressure (r = ?.749, p < .001 at the imposed, and r = ?.693, p < .001 at the preferred gait velocity). Displacement rate of center of pressure was strongly correlated with forefoot loading (r = ?.837, p < .001 at the imposed, and r = ?.731, p < .001 at the preferred gait velocity). People with a relatively high plantar flexion moment at 40% of the stance phase, have a faster forward transfer of center of pressure and consequently higher loading of the forefoot. This indicates that interventions aimed at increasing the control of the roll-off of the foot may contribute to a better plantar pressure distribution. 相似文献

Although the ability to stand from a seated posture is relevant for clinical practice, there are few studies investigating the process of acquisition and refinement of the motor components involved in sit-to-stand movement (STS) in children. Therefore, this longitudinal study aims to describe kinematic characteristics of the STS movement in children from 12 to 18 months, and also to investigate the relationship between changes in STS movement and childrens’ daily-life mobility. Ten healthy children were evaluated at 12,13,14,15 and 18 months of age. A motion analysis system was used to measure total duration of STS movement and angular movements of each joint, and frequencies of successful and unsupported STS were obtained. The Pediatric Evaluation of Disability Inventory was used to assess childrens’ daily-life mobility. Results showed that children tend to increase the frequency of successful trials over the months by reducing the total duration and decreasing peak ankle dorsiflexion and trunk flexion during STS. Children also started to stand up from chair with decreased trunk flexion angle among ages. At the end of the STS, we observed decreases in trunk flexion and knee flexion over age. Furthermore, kinematic characteristics that reflect improvements in STS movement are related to better performance of functional skills and decreased level of assistance provided by the caregiver in daily-life mobility of younger children. However, the strength of these associations decreases from 14 months of age onwards. 相似文献

The present study investigated the cross-sectional associations between cognitive biases (i.e., attentional bias and approach bias) and alcohol use and investigated the moderating role of gender, attentional control and inhibitory control. The sample consisted of 94 adolescents and young adults (52.1% boys) between 15.3 and 20.8 years old (Mage = 18.0, SD = 1.1) who reported drinking alcohol in the past three months. A stronger approach bias was related to higher alcohol use, albeit only among boys. Furthermore, the association between attentional bias and alcohol use was moderated by attentional control; the lowest alcohol use was found in adolescents with low attentional bias and high attentional control, suggesting protective effects of both variables. The present study replicates and extends the results of studies on cognitive biases and addiction in adolescence and young adulthood. 相似文献

RESUMENEn los últimos años se ha señalado, de forma excesiva, la eficacia de la modificación de conducta en el tratamiento de la anorexia nerviosa. Se ha supuesto, de forma errónea, que la imposición de una mejoría de la emaciación, el síntoma más llamativo, es un tratamiento adecuado para este trastorno tan grave y complejo. Los resultados que se han publicado adolecen de falta de seguimiento. En estos pacientes, este método de tratamientos les llevó a un empeoramiento de su estado. A pesar de conseguir un aumento de peso pasajero, la modificación de conducta debe considerarse como potencialmente dañina en la anorexia nerviosa. En este artículo se aporta información sobre los efectos perjudiciales de los pacientes tratados con este método. Sus historias ilustran que los métodos de modificación de conducta no son sólo peligrosos en potencia, sino en la realidad. 相似文献

ResumenDesde una perspectiva vygotskiana se revisa la evolución de las investigaciones relativas al desarrollo de la función reguladora del habla. Se discuten la metodología y el soporte conceptual de los estudios originales de Luria y de los intentos de replicación realizados por autores occidentales. Se presentan y comentan también varias aportaciones posteriores: tanto los nuevos planteamientos empíricos como los nuevos desarrollos conceptuales. Finalmente, se señala la necesidad de atender a nuevos criterios en la elección de las tareas, de registrar las verbalizaciones espontáneas y de analizar el proceso de sociogénesis. Se concluye identificando dos factores influyentes en la emisión del habla egocéntrica (dificultad relativa de la tarea y percepción del contexto social) y distinguiendo, dentro del funcionamiento de la autorregulación verbal, entre el sistema activador, ligado a los aspectos de impulso, y el sistema de planificación y control, asociado a la propiedad de mediación semiótica. 相似文献
