This study was done to verify a prediction in achievement goal-orientation theory in a Korean physical education setting. It was hypothesized that the interactions of situationally induced motivational climates (Task and Ego) and perceived competence would differentially influence anxiety and performance in tennis classes. 60 undergraduate men were assigned to a Task-involving and an Ego-involving program in tennis classes for 6 wk. Their perceptions of motivation climates and tennis competence were measured after the first 3 wk., and anxiety responses (cognitive and somatic) and tennis skill performance were evaluated every week over the second 3 wk. of the class. Analysis showed in Task-involving condition students decreased anxiety responses and increased tennis performance, whereas Ego-involving students who had low perception of their tennis competence maintained their anxiety responses and decreased their tennis performance. These results support the hypotheses and the predictions of goal-orientation theory and suggested practical application of the goal-orientation theory in Korea could be explored. 相似文献

Two waves of data from a family-focused preventive intervention project were used to test a model of the influence of protective
factors on young adolescents’ tendency toward alcohol abstinence. Prior theoretical and empirical work guided the specification
of hypothesized effects of the protective factors affectional relationship with parents, affiliation with prosocial peers,
and mastery-esteem on tendency toward alcohol abstinence. The tested model controlled for preintervention measures and included
specified interrelations of protective factors across time. Structural equation analysis indicated that the model fit the
data. Two of the hypothesized cross-time effects, however, were not supported.

This article reports differences across 23 countries on 2 processes of emotion regulation--reappraisal and suppression. Cultural dimensions were correlated with country means on both and the relationship between them. Cultures that emphasized the maintenance of social order--that is, those that were long-term oriented and valued embeddedness and hierarchy--tended to have higher scores on suppression, and reappraisal and suppression tended to be positively correlated. In contrast, cultures that minimized the maintenance of social order and valued individual Affective Autonomy and Egalitarianism tended to have lower scores on Suppression, and Reappraisal and Suppression tended to be negatively correlated. Moreover, country-level emotion regulation was significantly correlated with country-level indices of both positive and negative adjustment. 相似文献

Leisure items are commonly used as reinforcers in behavior-analytic applications. However, a defining feature of autism is the occurrence of stereotypy, and individuals with autism often engage leisure items in a stereotyped manner. The opportunity for stereotyped interaction may be the only aspect of a contingent stimulus that makes it a reinforcer for appropriate behavior. Therefore, this study investigated the effects of blocking stereotyped reinforcer interaction on reinforcer efficacy for 2 children with autism. Results showed that blocking stereotypic reinforcer interaction did not influence reinforcer efficacy. 相似文献

While organ transplantation has been established in the medical imagination since the 1960s, this technology is currently undergoing a popular re-imagination in the era of global capitalism. As transplantation procedures have become routine in medical centers in non-Western and developing nations and as organ sales and transplant tourism become increasingly common, organs that function as a material resource increasingly derive from subaltern bodies. This essay explores this development as represented in Korean filmmaker Park Chan-wook's 2002 Sympathy for Mr. Vengeance, focusing on the ethnic and class characteristics of the global market in organs and possible modes of counter-logic to transplant technologies and related ethical discourses. 相似文献

In this study, we examined mechanisms that underlie free-recall performance in bilinguals' first language (L1) and second language (L2) through the prism of serial-position effects. On free-recall tasks, a typical pattern of performance follows a U-shaped serial-position curve, where items from the beginning of the list (the primacy effect) and items from the end of the list (the recency effect) are recalled with higher accuracy than items from the middle of the list. The present study contrasted serial-position effects on the free-recall task in Korean-English bilinguals' L1 vs. L2 and examined the relationship between an independent working memory (WM) measure and serial-position effects in bilinguals' two languages. Results revealed stronger pre-recency (primacy and middle) effects in L1 than in L2, but similar recency effects in the two languages. A close association was observed between WM and recall performance in the pre-recency region in the L1 but not in the L2. Together, these findings suggest that linguistic knowledge constrains free-recall performance in bilinguals, but only in the pre-recency region. 相似文献

An inexpensive remote radio control system for slide projection has been developed. It consists of an electronic receiver/decoder designed for attachment to commercially available slide projectors and a self-contained, portable FM transmitter with a foldable (collapsible) antenna/pointer. The system allows remote lens focusing (forward and backward) and slide change (forward and reverse) to be accomplished over a 100-ft range. It offers desirable freedom of movement to the lecturer or behavioral researcher, by eliminating locational restraints imposed by the extension cord. 相似文献

The aim of this research was to quantify the coordination pattern between thorax and pelvis during a golf swing. The coordination patterns were calculated using vector coding technique, which had been applied to quantify the coordination changes in coupling angle (γ) between two different segments. For this, fifteen professional and fifteen amateur golfers who had no significant history of musculoskeletal injuries. There was no significant difference in coordination patterns between the two groups for rotation motion during backswing (p = 0.333). On the other hand, during the downswing phase, there were significant differences between professional and amateur groups in all motions (flexion/extension: professional [γ] = 187.8°, amateur [γ] = 167.4°; side bending: professional [γ] = 288.4°, amateur [γ] = 245.7°; rotation: professional [γ] = 232.0°, amateur [γ] = 229.5°). These results are expected to be a discriminating measure to assess complex coordination of golfers' trunk movements and preliminary study for interesting comparison by golf skilled levels. 相似文献
