Increased hypothalamic-pituitary-adrenal (HPA) activation, culminating in elevated circulating cortisol levels is a fundamental response to stressors. In animals, this neuroendocrine change is highly reliable and marked (approximately 5-10-fold elevations), whereas in humans, the increase of cortisol release is less pronounced, and even some potent life-threatening events (anticipation of surgery) only elicit modest cortisol increases. Meta-analysis of factors that influenced the increase of cortisol release in a laboratory context pointed to the importance of social evaluative threats and stressor controllability in accounting for the cortisol rise. The present meta-analysis, covering the period from 1978 through March 2007, was undertaken to identify the factors most closely aligned with cortisol increases in natural settings. It appeared that stressor chronicity was fundamental in predicting cortisol changes; however, this variable is often confounded by the stressor type, the stressor's controllability, as well as contextual factors, making it difficult to disentangle their relative contributions to the cortisol response. Moreover, several experiential factors (e.g. previous stressor experiences) may influence the cortisol response to ongoing stressors, but these are not readily deduced through a meta-analysis. Nevertheless, there are ample data suggesting that stressful events, through their actions on cortisol levels and reactivity, may influence psychological and physical pathology. 相似文献

This research describes an exploratory factor analysis for the purposes of factorial validation for both the English and Japanese
versions of the Objective Measure of Ego-Identity Status (OMEIS)—Ideological version (Adams, Bennion, & Huh, 1989). The Japanese
OMEIS is a direct translation of the English OMEIS (Ohnishi, 1998). The study reports the factor structure of the OMEIS—Ideological
version in English and Japanese. A principal factor analysis (PFA) with both oblique and orthogonal solutions was performed.
Alpha reliabilities for the factors are presented. The present research compares and contrasts the factor structures of OMEIS—Ideological
version, derived from a U.S. sample and a Japanese sample, comprising women from late adulthood to middle age. Cultural differences
between the two sample populations are explored. 相似文献

A philosophical theory of religion ought to meet four criteria: it should be extensionally accurate, neutral, phenomenological,
and non-circular. I argue that none of the popular theories of religion meet all these criteria, and that, in particular,
the extensional accuracy criterion and the non-circularity criterion can’t be met without sacrificing extensional accuracy.
I conclude that, therefore, religions do not form a kind, and so, there is no such thing as religion.

ObjectivesTo investigate the efficacy of a motivational general-arousal based imagery strategy in modifying precompetitive symptom interpretations.MethodA staggered multiple baseline single-subject design was employed with five male collegiate rugby union players (M = 24.5; SD = 3.05). The dependent variable was monitored over a full competitive season via measures of precompetitive anxiety and affect together with follow-up social validation procedures.ResultsMore facilitative interpretations of symptoms associated with competitive anxiety, and greater self-confidence levels were reported postintervention, together with changes in positive and negative affect.ConclusionsThe findings highlight the importance of employing individualized imagery with motivational general-arousal content to modify performers' perceptions of their precompetitive experiences. This effect is proposed to occur directly through adaptive changes in individuals' psychological response systems and indirectly via the protection mechanisms associated with enhanced efficacy expectations. 相似文献

Functional analyses sometimes do not identify momentary fluctuations in the function of destructive behavior (Bowman, Fisher, Thompson, & Piazza, 1997). In such cases, individuals may mand for the reinforcer that is currently most preferred and display destructive behavior if that mand goes unreinforced. In this study, we conducted a mand analysis to test whether destructive behavior functioned as a precurrent response that increased reinforcement for the participant's mands. We then evaluated a treatment that matched this function of destructive behavior by providing differential or time-based reinforcement of participant mands in accordance with multiple or chained schedules with reinforcement-schedule thinning. Decreases in destructive behavior averaged 97.4% across cases. We discuss these results relative to the importance of matching treatments for destructive behavior to operant functions for both traditional and idiosyncratic functions of destructive behavior. 相似文献
