改变“低挫折容忍度”的心理干预及效果评估 —— 一位奥运银牌运动员的个案研究 总被引:1,自引:0,他引:1
研究目的是描述对一名奥运选手L在奥运会前一年中进行的心理干预,以改变其“低挫折容忍度”的过程,以及评价这一理性情绪行为疗法与心理技能训练相结合的心理干预的效果。在不同的时间点采用各种评估方法对干预效果进行评估,主要的评估方法包括采用目标获得评价表进行的运动员L自我评估和教练员评估,运动员L、教练员、及搭档的“阶段性总结”评价,以及对L比赛行为的录像资料分析。通过各种评估方法所获得的结果的一致性证明了该干预方法在改变运动员的问题行为方面是有效的。通过对运动员L的问题行为的改变,提升了他在比赛中的运动表现,该运动员与其搭档在2004年雅典奥运会乒乓球男子双打项目上获得了银牌 相似文献

Bayesian IRT Guessing Models for Partial Guessing Behaviors 总被引:1,自引:0,他引:1
According to the recent Nation’s Report Card, 12th-graders failed to produce gains on the 2005 National Assessment of Educational
Progress (NAEP) despite earning better grades on average. One possible explanation is that 12th-graders were not motivated
taking the NAEP, which is a low-stakes test. We develop three Bayesian IRT mixture models to describe the results from a group
of examinees including both nonguessers and partial guessers. The first assumes that the guesser answers questions based on
his or her knowledge up to a certain test item, and guesses thereafter. The second model assumes that the guesser answers
relatively easy questions based on his or her knowledge and guesses randomly on the remaining items. The third is constructed
to describe more general low-motivation behavior. It assumes that the guesser gives less and less effort as he or she proceeds
through the test. The models can provide not only consistent estimates of IRT parameters but also estimates of each examinee’s
nonguesser/guesser status and degree of guessing behavior. We show results of a simulation study comparing the performance
of the three guessing models to the 2PL-IRT model. Finally, an analysis of real data from a low-stakes test administered to
university students is presented. 相似文献

Self-focused attention has been found to facilitate task performance in some instances and inhibit it in others. Among chronically anxious individuals it appears to consistently hinder performance. Less is known about the impact of self-focus on the performance of normal individuals. The present study examines the role of task difficulty, task self-relevance, and presence of evaluation anxiety in the performance effects of self-focus among normal individuals. Participants performed a simple reaction time (RT) and a lexical decision task, in Experiments 1 and 2, respectively, with or without self-focus. Self-focus and evaluation anxiety resulted in faster responding in simple RT, but there was no significant effect of self-focus on performance in the more difficult lexical decision task. Participants' heart rate (HR) was monitored and indicated that orienting was associated with slower RT in both experiments, and less orienting was found during self-focus and evaluation conditions. Results are interpreted in light of several self-focus theories. 相似文献

Depression in early puerperium was evaluated in terms of maternal attachment in mothers of children admitted to the neonatal intensive care unit (NICU) in comparison to a control group of mothers of full‐term infants. A survey including Zung's self‐rating depression scale (ZSDS), a postpartum maternal attachment scale and items addressing the mother's feelings and peripheral conditions was conducted on mothers of children admitted to the NICU. Among the 153 mothers who gave valid responses, positive ZSDS scores of over 40 were seen in 61.8%. In terms of the children's disorder, strong depressive tendency was noted among mothers of low birth weight infants. Significant correlation was noted between the ZSDS and the ‘core maternal attachment’ (negative correlation) and ‘anxiety regarding children’ (positive correlation) subscales of postpartum maternal attachment. Path analysis revealed the father's positive reaction in learning of the pregnancy resulted in elevation of the ‘core maternal attachment’ score, in contrast to the control group mothers.

Newell, Mitchell, and Hayes (NMH) conduct three experiments designed to test whether exemplar cuing (EC) theory or a statistical format theory provides a more accurate account for how people make judgments about low‐probability events. They report finding support for the statistical format theory and little or no support for EC. However, NMH misstate the requirements for the production of exemplars in EC theory. As a result, they confuse non‐exemplar conditions with exemplar conditions in their experiments, and find results that are virtually irrelevant to EC theory.

Pigeons' key pecking was reinforced by food delivered by several fixed-interval, variable-ratio, and differential-reinforcement-of-low-rate schedules. Rate of responding, number of responses per reinforcer, length of postreinforcement pause, running response rate, and the time required to collect an available reinforcer changed systematically within sessions when the schedules provided high rates of reinforcement, but usually not when they provided low rates. These results suggest that the factors that produce within-session changes in responding are generally similar for different schedules of reinforcement. However, a separate factor may also contribute during variable-ratio schedules. The results question explanations for within-session changes that are related solely to the passage of time, to responding, and to one interpretation of attention. They support the idea that one or more factors related to reinforcement play a role. 相似文献

The accuracy of depressed and nondepressed subjects' perceptions of their own and a social interactional partner's performance was investigated. Twenty depressed and twenty nondepressed college students participated in dyadic interactions and then rated their own and their partner's social behavior. The interactions were also rated by objective coders. Depressed subjects were differentiated from nondepressed subjects on several measures by both the coders and the subjects. Depressed subjects' self-ratings were correlated with the coders' ratings more often than were the nondepressives' ratings, suggesting depressives provided more accurate self-observations. Contrary to prediction, depressives were also more accurate in judging their partner's behavior. Depressives experienced heightened levels of self-focused attention, but this attentional focus did not mediate the relationship between depression level and self-accuracy. Finally, an analysis of the verbal statements suggests that performance differences between depressives and nondepressives may be a function of the quantity, rather than the quality, of the verbal production. 相似文献

In Experiment 1 rats were trained to press a lever on a variable-ratio schedule of food presentation and were then exposed to progressively increasing magnitudes of food reinforcement. Response running rates (rates exclusive of the postreinforcement pause) were found to increase as a function of increasing reinforcement magnitudes. The effect of reinforcement magnitude on response rates inclusive of the postreinforcement pause, however, was less pronounced. Increases in the magnitude of reinforcement were also found to increase the length of the postreinforcement pause. Rats in Experiment 2 were trained to respond on a chained differential-reinforcement-of-low-rate variable-ratio schedule, and were exposed to increasing magnitudes of reinforcement as in Experiment 1. Response running rates increased in the variable-ratio component but decreased in the other component of the schedule. The results are discussed with reference to incentive accounts of reinforcement and the action of reinforcement on the response units generated by the operative contingencies. 相似文献

Vocal stereotypy (VS) is often observed in individuals with autism spectrum disorder (ASD) which at high rates can interfere with socialization or functioning in structured settings. There are multiple effective interventions available; yet, many procedures target the complete omission of the behavior or are only assessed at short intervals, making it unclear how they will generalize in applied settings. One intervention yet to be assessed as an individual intervention for automatically reinforced VS is differential reinforcement of low rates of behavior (DRL). In the present study, a functional analysis determined that the VS of two female adolescents with ASD was maintained by automatic reinforcement. A DRL procedure was implemented which incorporated: (a) a specified interval for reinforcement; (b) the behavioral expectations; (c) the permissible instances of VS within the interval; (d) learner feedback; and (e) the reset/non-reset aspect of the schedule. As the targeted behavior decreased across sessions, the DRL interval was systematically increased in order to thin out the schedule of reinforcement. The intervention reduced VS and increased untargeted task engagement for both participants. Applied and theoretical implications of the study as well as social validity, limitations, and future research are discussed. 相似文献
