A naturally occurring experiment, in which direct supervision of a token economy in a penal system was removed and re-instated, is reported. A retrospective analysis revealed that in the absence of close supervision the use of response cost rose dramatically, both in terms of categories of behaviors for which response costs were levied and in the frequency of their use. The return of direct supervision led to a decreased use and an end to the growth of categories of behaviors punished. 相似文献

As their eye movements were being monitored, college students read short texts displayed on a cathode-ray tube. As they read, the contents of certain word locations changed from fixation to fixation, alternating between two words differing in two letters. This manipulation had no effect on reading unless the subjects happened to regress to or reread the word later. The results indicated that these words, which were low in contextual constraint, were read only when directly fixated, and that there was no facilitation from prior peripherally obtained information about the words. 相似文献

The primary purpose of this study was to examine the relationships between psychological need satisfaction (competence, autonomy, and relatedness), exercise regulations, and motivational consequences proposed by Self‐Determination Theory (SDT; Deci & Ryan, 1985; Ryan & Deci, 2000). The secondary purpose was to explore changes in these constructs over the course of a 12‐week prescribed exercise program. Results indicated competence and autonomy were positively correlated with more self‐determined exercise regulations, which in turn were more positively related to exercise behavior, attitudes, and physical fitness. Multiple regression analyses revealed that exercise behavior mediated the relationship between self‐determined motives and physical fitness, and both identified and intrinsic exercise regulations contributed significantly to the prediction of attitudes. Paired‐sample t tests supported modest to large changes in need satisfaction constructs, as well as identified and intrinsic regulations over the 12‐week exercise program. These results suggest that SDT is a useful framework for studying motivational issues in the exercise domain. 相似文献

Human beings seem to be resilient and have a great capacity to overcome adverse circumstances. One apparent variable that may predict people's emotional and physical health after a trauma is their general level of psychological well‐being ( McMillen, Smith, & Fisher, 1997 ). The current study explores the role of subjective vitality and the perception of stress as mediators between general life satisfaction and post‐trauma physiological and psychological health related to the Canadian 1998 Ice Storm. Results of this dual route indicate that satisfaction with life positively predicted subjective vitality and negatively predicted perceived stress. In turn, subjective vitality lead to lower levels of ill‐health, whereas perception of stress lead to higher levels of physical symptoms and depression. 相似文献

This research aimed to investigate the changes in judgment accuracy, confidence, control thresholds, and decision outcomes when people act in two-person groups (dyads) compared with acting individually. First, we used interacting dyads to determine the metacognitive and behavioral outcomes of collective decision making and compared them with those of individuals. Second, we examined whether these changes were related to the trait-confidence and bias of individuals working together. Using a within-person design, undergraduate psychology students (N = 116) completed a General-knowledge Test individually, then together as a dyad. Each question was accompanied by a confidence rating and a decision to bet $10 on the answer. Dyads had significantly higher confidence and lower control thresholds than individuals. They were also significantly more decisive (made more bets) and reckless (lost a higher rate of bets) than when working alone. Thus, we observed a higher rate of decision errors for groups than individuals. The results also demonstrated the important role of individual differences: Overconfident individuals became even more confident, decisive, and reckless when working together compared with less confident or underconfident individuals working together. These findings have important theoretical and applied implications for collective decision making; metacognitive bias and potentially control thresholds may be targeted to alleviate the larger error rates and guide the formation of more effective groups. 相似文献

The researchers examined the effects of reducing attentional demands on reading comprehension test scores. Third grade students (N=939) completed two forms (T & S) of the Stanford 9 Reading Comprehension Test (54 items, 50 min.) in the spring of 1999. Form T (state-mandated) was administered following standardized procedures in one session. Form S (alternate) was administered in multiple, divided-time sessions, that is, the total test time and items were divided in halves and thirds per session to lessen attentional demands. A repeated-measure analysis of variance yielded significant effects for average and low readers. A resource match explanation and a metacognitive explanation are offered for the results, and educational implications are discussed. 相似文献

This study investigated whether being charged with a child pornography offense is a valid diagnostic indicator of pedophilia, as represented by an index of phallometrically assessed sexual arousal to children. The sample of 685 male patients was referred between 1995 and 2004 for a sexological assessment of their sexual interests and behavior. As a group, child pornography offenders showed greater sexual arousal to children than to adults and differed from groups of sex offenders against children, sex offenders against adults, and general sexology patients. The results suggest child pornography offending is a stronger diagnostic indicator of pedophilia than is sexually offending against child victims. Theoretical and clinical implications are discussed. 相似文献
