学习困难和优秀学生延迟满足能力的跨情境比较实验研究 总被引：1，自引：1，他引：0
探讨学习困难学生(学困生)和学习优秀学生(学优生)在三种不同情境下——独自操作、单一团体操作和混合团体操作,延迟满足能力的差异.结果表明:(1)在延迟满足实验中,被试变量(学优生、学困生)与情境变量(独自、单一团体、混合团体)的交互作用显著;(2)在独自操作和单一团体情境下,学优生延迟满足能力显著高于学困生,混合团体则不存在这种差异;(3)学优生的延迟满足能力在独自操作和单一团体时水平较高,而混合团体的成绩则显著的低于单一团体,学困生的延迟满足能力在单一团体和混合团体时水平较高,而单独操作成绩则显著低于混合团体.本研究一方面拓展了对延迟满足能力的群体比较研究,同时,对学困生的心理教育实践也有指导意义. 相似文献

本研究基于评估倾向理论, 通过3项实验考察了特定负性情绪(愤怒)对延迟折扣的影响, 并探究确定感和控制感评估倾向在这一关系中的作用。实验1考察愤怒情绪对延迟折扣的影响, 结果发现, 愤怒组被试的延迟满足倾向显著强于恐惧组和控制组。实验2采用实验因果链设计考察确定感和控制感评估倾向在愤怒情绪影响个体延迟折扣中的作用, 结果发现, 愤怒情绪可以有效增强个体的确定感和控制感(实验2a), 同时确定感和控制感能够增强个体的延迟满足倾向(实验2b)。实验3采用中介测量设计考察确定感和控制感评估倾向在愤怒情绪影响个体延迟折扣中的作用, 结果发现, 确定感和控制感评估倾向在愤怒情绪影响个体延迟折扣中起完全中介作用。本研究结果表明, 当个体进行跨期决策时, 体验到与确定感和控制感有关的偶然愤怒情绪会增强其延迟满足倾向。本研究对探究特定负性情绪对个体延迟折扣的影响具有一定的启示意义。 相似文献

对过去事件的加工涉及到对现在信息的加工,过去获得的价值能够为现在的生活带来的收益可能对过去事件的价值估计具有影响。本研究探讨了过去事件对现在生活的影响在过去时间贴现中的作用。采用延迟时间贴现范式任务,选取2周到50年共10个过去时间长度,要求被试在现在获得的奖金和过去获得的奖金之间进行偏好选择,并且完成对过去时间贴现决策策略的问题回答。采用曲线下的单位面积UAUr(t1,t1) 为过去时间贴现率,发现过去时间贴现率在过去2周和过去1个月之间[Z = 2.662,p = .008]、过去1年和过去3年之间[Z = 2.587, p = .010] 差异显著。对决策策略的回答进行内容分析(频次统计信度为0.875),发现过去事件能够为现在生活带来的收益影响了被试对过去事件的价值估计和偏好选择。从现在起到过去2周内,被试看重近的过去获得的奖金对现在的生活的帮助,偏好选择过去获得的奖金;在较远的过去,从过去2周起到过去1年内,奖金数量和获得奖金的时间之间的比例影响了被试的偏好选择;从过去1年起到过去50年内,远的过去获得的奖金对现在生活的影响微乎其微,被试偏好现在获得的奖金。本研究的结果支持了过去时间贴现和未来时间贴现具有不同的心理加工机制,并且有助于进一步了解过去时间的差别感受性的变化规律。 相似文献

The study explores the effect of trait reactance on procrastination and delay in students of two study programmes differing in the structuring of academic tasks and the role they play in course assessment. Both subsamples (n = 97 and 139) completed measures of trait reactance, chronic academic procrastination, self-reported task procrastination and actual task delay. The data were analyzed using path analysis and SEM. As hypothesized, psychological reactance positively predicted procrastination, especially the ‘chronic delay’ component underlying all three procrastination-related measures. However, some of the effect of reactance on this delay-dependent component of procrastination was apparently suppressed by what might have been a subjective (delay-independent) component of self-reported task procrastination. Furthermore, reactance was significantly related to delay only when good performance on the task was of relatively high importance. Apart from providing evidence for a possible link between reactance and procrastination, the results also demonstrate that it is important to distinguish between the experiential and objective (temporal) components of procrastination, as the two might be represented by completely different nomological networks. 相似文献

When the temporal interval or delay separating cause and effect is consistent over repeated instances, it becomes possible to predict when the effect will follow from the cause, hence temporal predictability serves as an appropriate term for describing consistent cause-effect delays. It has been demonstrated that in instrumental action-outcome learning tasks, enhancing temporal predictability by holding the cause-effect interval constant elicits higher judgements of causality compared to conditions involving variable temporal intervals. Here, we examine whether temporal predictability exerts a similar influence when causal learning takes place through observation rather than intervention through instrumental action. Four experiments demonstrated that judgements of causality were higher when the temporal interval was constant than when it was variable, and that judgements declined with increasing variability. We further found that this beneficial effect of predictability was stronger in situations where the effect base-rate was zero (Experiments 1 and 3). The results therefore clearly indicate that temporal predictability enhances impressions of causality, and that this effect is robust and general. Factors that could mediate this effect are discussed. 相似文献

Standard models of intertemporal choice assume that individuals discount future payoffs by integrating reward amounts and time delays to generate a discounted value. Alternative models propose that, rather than integrate across them, individuals compare within attributes (amounts and delays) to determine if differences in one attribute outweigh differences in another attribute. For instance, the similarity model 1) compares the two reward amounts to determine whether they are similar, 2) compares the similarity of the two time delays, and then 3) makes a decision based on these similarity judgments. Here, I tested discounting models against attribute‐based models that use similarity judgments to make choices. I collected intertemporal choices and similarity judgments for the reward amounts and time delays from participants in three experiments. All experiments tested the ability of discounting and similarity models to predict intertemporal choices. Model generalization analyses showed that the best predicting models started with similarity judgments and then, if similarity failed to make a prediction, resorted to discounting models. Similarity judgments also matched intertemporal choice data demonstrating both the magnitude and sign effects, thereby accounting for behavioral data that contradict many discounting models. These results highlight the possibility that attribute‐based models such as the similarity models provide alternatives to discounting that may offer insights into the process of making intertemporal choices.

The present study required 9 disordered gamblers to make hypothetical selections between smaller and larger amounts of money at varying delays. Participants were also required to respond to the task given the contrived hypothetical conditions of earning twice or half as much as they did at their current jobs. The results demonstrated how participants’ delay discounting was altered via contrived motivating operations, strengthening the argument that discounting may be a state variable. 相似文献
