The purpose of this study was to explore the relationship of spiritual beliefs and involvement with anger and stress in early
adolescents. Early adolescents (n = 53) completed the Spiritual Involvement and Beliefs Scale (Hatch et al. 1998), the State-Trait Anger Expression Inventory (Spielberger 1999), and the Perceived Stress Scale (Cohen and Williamson 1988). Contrary to expectations, spirituality was significantly and positively related to anger and stress. Implications and possible
explanations for the unanticipated findings in this study are discussed. 相似文献

Abstract The effects of performance strategies, goal setting, and self-evaluative recording on the acquisition of a novel motoric skill were studied with 90 high school girls. It was hypothesized that greater acquisition would occur when (a) an analytic strategy was used instead of imaginal strategy, (b) practice goals were shifted dynamically during learning instead of remaining unchanging or fixed, and (c) self-evaluative recording of strategic performance processes was present rather than absent. Support for all three hypotheses was found. In addition to improving motoric skill acquisition, these same self-regulatory processes significantly enhanced three sources of learners' motivation: self-efficacy beliefs, self-satisfaction, and intrinsic interest. Additional analyses revealed that self-evaluative recording enhanced strategy attributions during learning which were predictive of improved self-efficacy, self-satisfaction, and intrinsic interest during posttesting. Self-efficacy was highly predictive of subsequent dart-skill performance. The results were discussed in terms of a strategic cycle view of self-regulation of motoric learning. 相似文献

Response speed and accuracy of 48 general aviation pilots were determined under condition of anticipatory physical threat stress (APTS). Variables included unpleasantness of the event (electrical shock), proximity of the event, and relationship of Ss’ performance to the occurrence of the event. The data support inclusion of these variables in Wherry’s model of APTS. Ss who believed they could avoid the shock by an adequate performance were able to maintain or improve that performance while the performance of Ss who perceived the shock as inevitable was deteriorating. Two possible modifications of the APTS model were discussed: (1) weighting APTS determiners according to their effectiveness in generating anticipatory stress, (2) recognizing the interaction of the APTS variables with S’s personality structure. 相似文献

The authors investigated how brain activity during motor-memory consolidation contributes to transfer of learning to novel versions of a motor skill following distinct practice structures. They used 1 Hz repetitive Transcranial Magnetic Stimulation (rTMS) immediately after constant or variable practice of an arm movement skill to interfere with primary motor cortex (M1) or dorsolateral prefrontal cortex (DLPFC). The effect of interference was assessed through skill performance on two transfer targets: one within and one outside the range of practiced movement parameters for the variable practice group. For the control (no rTMS) group, variable practice benefited delayed transfer performance more than constant practice. The rTMS effect on delayed transfer performance differed for the two transfer targets. For the within-range target, rTMS interference had no significant affect on the delayed transfer after either practice structure. However, for the outside-range target, rTMS interference to DLPFC but not M1 attenuated delayed transfer benefit following variable practice. Additionally, for the outside-range target, rTMS interference to M1 but not DLPFC attenuated delayed transfer following constant practice. This suggests that variable practice may promote reliance on DLPFC for memory consolidation associated with outside-range transfer of learning, whereas constant practice may promote reliance on M1 for consolidation and long-term transfer. 相似文献

More must be learned of color and its possible relationships with the Rorschach before its interpretation may be taken with assurance. Twenty Ss were administered the Rorschach and a Color Battery of four tasks chosen to tap color preference. Preferences were analyzed for use of the color on the Rorschach plates; color response scores and form-level scores; relationship with color meaning for the subject. Significances were found between: (1) preference and use of color; (2) preference and CF and C scores; (3) plus form-level and preferences. Color meanings varied with each subject. Color preference may influence the subject's use of color on the Rorschach, as well as scores, regardless of what the preferred color may be or the amount available. Generalizations are not warranted on the basis of color or color use, especially as regards differential diagnosis. 相似文献

Thirty-six three-, four-, and five-year-old boys and girls were asked to act out, with appropriate toys, 48 sentences presented with instructions to make the toys do what E said. Sentences were designed to test the effects on comprehension of (a) event probability, (b) sentence voice, and (c) subject/object animateness. Sentences with either an animate subject and object, or an inanimate subject and object, were considered to be reversible; however, not all reversible sentences were symmetrical with respect to event probability. All main effects were significant, and performance improved with age. The significant interactions indicated that there is a difference between animateness and inanimateness in reversible sentences. The data also suggested that (a) animateness may be an important variable in children's early comprehension of speech, and (b) the traditional definition of reversibility should be modified to unconfound the effects of event probability and animateness. 相似文献

Classical cross-country skiing can be performed using three main techniques: diagonal stride (DS), double poling (DP), and double poling with kick (DK). Similar to other forms of human and animal gait, it is currently unclear whether technique selection occurs to minimize metabolic cost or to keep some mechanical factors below a given threshold. The aim of this study was to find the determinants of technique selection. Ten male athletes roller skied on a treadmill at different slopes (from 0° to 7° at 10 km/h) and speeds (from 6 to 18 km/h at 2°). The technique preferred by skiers was gathered for every proposed condition. Biomechanical parameters and metabolic cost were then measured for each condition and technique. Skiers preferred DP for skiing on the flat and they transitioned to DK and then to DS with increasing slope steepness, when increasing speed all skiers preferred DP. Data suggested that selections mainly occur to remain below a threshold of poling force. Second, critically low values of leg thrust time may limit the use of leg-based techniques at high speeds. A small role has been identified for the metabolic cost of locomotion, which determined the selection of DP for flat skiing. 相似文献

Abstract For several decades family theorists, researchers, and clinicians have attempted to describe healthy and dysfunctional family functioning. The numerous articles and studies with this focus have been reviewed elsewhere (Riskin & Faunce, 1972; Jacob, 1975). Until recently a disproportionate amount of attention has been given to pathology. Several volumes in the past few years have tried to redress this bias by focusing primarily on healthy family functioning (Kantor & Lehr, 1976; Lewis, Beavers, Gossett & Phillips, 1976). 相似文献
