初中学业不良学生习得性无能研究

采用两个２×２实验设计,研究强化方式、成就状况和任务类型对初中学业不良学生习得性无能倾向的影响二结果表明：外部奖赏不能提高成功组学生的内在动机,反而增加挫折组学生的无力感与挫折感;操作作业的成败对学生习得性无能倾向影响不明显,而数学作业的成败的影响则非常显著;学生在操作作业中的内在动机明显高于其在数学作业中的内在动机。     

Deci and Ryan's cognitive evaluation theory of intrinsic motivation: A set of common sense theorems

Cognitive evaluation theory as put forward by Deci and Ryan (1985) is examined. The theory, which deals with intrinsic and extrinsic motivation, has inspired considerable amount of empirical research in the last two decades. However, contrary to the mainstream view and that of its authors, it is argued here that the theory consists of necessary truths of common sense (folk) psychology, rather than contingent and empirically testable hypotheses. As such the theory spells out what must necessarily be the case in human motivation and the empirical evidence amassed to test its validity is irrelevant. Such testing should be abandoned if its purpose is to appraise the truth value of the theory's propositions. To empirically test necessary true propositions is not only redundant in such cases, but also a waste of time and resources.     

Variation in arm-choice strategies of rats in radial-maze tasks

Rats were trained with three delay-interpolated tasks in a radial-arm maze. The tasks differed in the post-delay bait conditions. When every arm was baited in the post-delay free choices (Task E8B), rats made adjacent-arm choices frequently. When only the four arms unvisited in the pre-delay forced choices were baited after delay (Task U4B), rats chose unvisited arms preferentially, with frequent arm investigations. When four quasi-randomly selected arms were baited after delay (Task R4B), rats did not choose adjacent arms as frequently as the rats in Task E8B did, and made fewer arm investigations. These results indicate that the rats developed different arm-choice strategies in accordance with tasks. As for the effects of rewarding, post-delay choice behavior was not affected by the pre-delay bait conditions.     

Gender Differences in Preferences for Singles Ads that Proclaim Extrinsic Versus Intrinsic Values

Two studies (Ns = 1,113 and 98) examined University men and womens’ differing preferences for singles ads as a function of the values declared by ad-writers, using Kasser and colleagues’ distinction between extrinsic values (financial success, status/fame, and image/attractiveness) and intrinsic values (emotional intimacy, community contribution, and personal growth). In general, participants preferred writers espousing intrinsic values. Women, compared to men, especially preferred partners espousing intrinsic values. They also expressed less interest in partners espousing extrinsic values, with one exception: compared to men, they were more interested in partners espousing financial success values. Implications for debates regarding the evolved versus sociological origins of gender differences are discussed, as well as implications for theories of attraction based on the matching hypothesis.     

Improving judgement with prepaid expert advice

Decision makers (“Judges”) often make decisions after obtaining advice from an Advisor. The two parties often share a psychological “contract” about what each contributes in expertise to the decision and receives in monetary outcomes from it. In a laboratory experiment, we varied Advisor Experitise and the opportunity for monetary rewards. As expected, these manipulations influenced advice quality, advice taking, and Judge post‐advice decision quality. The main contribution of the study, however, was the manipulation of the timing of monetary rewards (before or after the advising interaction). We found, as predicted, that committing money for expert—but not novice—advice increases Judges' use of advice and their subsequent estimation accuracy. Implications for advice giving and taking are discussed. Copyright © 2004 John Wiley & Sons, Ltd.     

奖励对创造力的影响及其机制

在奖励对创造力的影响的问题上, 相关研究一直存在很大争议。在系统分析以往研究的基础上, 认为奖励既可以促进创造力也可以阻碍创造力, 这取决于对奖励的界定及对创造力的理解, 也受个体差异和外部环境因素的影响。在作用途径上, 奖励可以通过动机或认知因素以及它们的综合作用对创造力产生影响。研究在此基础上构建出一个综合了奖励和创造力及其影响因素的模型。     

Providing a Rationale in an Autonomy-Supportive Way as a Strategy to Motivate Others During an Uninteresting Activity

When motivating others during uninteresting activities, people typically use extrinsic contingencies that promote controlling forms of extrinsic motivation. In contrast, we investigated a motivational strategy that could support another person's capacity to personally endorse and value the effort he or she put forth during the uninteresting activity. That strategy is the provision of an externally provided rationale when communicated in an autonomy-supportive way. In two studies, we tested and found support for a motivational mediation model, based on self-determination theory, in which the presence of such a rationale (vs. its absence) adds to participants' identification with the task's personal value which, in turn, explains participants' subsequent effort. These studies suggest that extrinsically motivated behaviors can become self-determined through the process of identification and that the promotion of this identification experience depends on the presence of a rationale that is communicated in an autonomy-supportive way.     

Comparing rapid assessments of delay discounting with real and hypothetical rewards in children

Recent advances in assessment methodology have resulted in a highly efficient procedure for obtaining delay discounting rates for adults: a 5‐trial adjusting delay task (ADT‐5) examining intertemporal choice for hypothetical rewards. The low participant burden of this task makes it potentially useful for children, with whom delay discounting research is relatively limited. However, it is unknown whether results from this task match choice for real rewards. The present study assessed delay discounting for real and hypothetical monetary rewards using a modified ADT‐5 with 9 children admitted to a psychiatric day treatment program. Participants completed up to 3 tasks with each reward type in alternating order. No difference in discounting rate, via log(k), was observed between the first task of each reward type. This finding was replicated across subsequent tasks for the subset of participants (n = 6) who completed all 6 tasks. However, delay discounting of real and hypothetical rewards was not found to be statistically equivalent. These results suggest that a modified ADT‐5 using hypothetical rewards may be a viable option for assessing delay discounting in children with psychiatric diagnoses, but additional research is needed to explicitly examine whether hypothetical and real rewards are discounted equivalently in this population.     

大学生目标内容与主观幸福感的关系：一个有调节的中介模型

基于自我决定理论考察了目标内容对主观幸福感的影响,以及基本心理需要、自尊在其中的作用。采用欲望指数量表、基本心理需要满足量表、自尊量表、正负情绪量表、生活满意度问卷对535名大学生进行了调查。结果显示：（1）目标内部性显著正向预测主观幸福感;（2）基本心理需要在目标内部性和主观幸福感之间起部分中介作用;（3）基本需要的中介作用受到自尊的调节。因此,目标内部性对主观幸福感的影响是一个有调节的中介效应。     

Reasons to Desire and Desiring at Will

There is an unresolved conflict concerning the normative nature of desire. Some authors take rational desire to differ from rational belief in being a normatively unconstrained attitude. Others insist that rational desire seems plausibly subject to several consistency norms. This article argues that the correct analysis of this conflict of conative normativity leads us to acknowledge intrinsic and extrinsic reasons to desire. If sound, this point helps us to unveil a fundamental aspect of desire, namely, that we cannot desire at will. Unlike belief, however, desire can unproblematically accommodate a notion of instrumental attitude.
