摘要:通过两个实验考察任务类线索(词频、关联性、学习次数)对学习难易度判断及其准确性的影响。结果表明:(1)词频和关联性对学习难易度判断均有显著影响,高频词对、有关联词对的预测成绩显著高于低频词对和无关联词对的预测成绩;(2)高频词对和低频词对的预测成绩均出现高估,但低频词对的估计更准确;有无关联词对相比,无关联词对预测成绩偏差更大,有关联词对的难易度判断更准确;(3)词频高低只影响成绩的预测,不影响实际回忆成绩;关联性既影响对成绩的预测,也影响实际回忆成绩。(4)学习次数对难易度判断没有显著影响,但随学习次数增加,判断准确性降低,出现低估现象。结论:材料因素对学习难易度判断等级具有较稳定的影响;不同材料因素(词频、关联性)对难易度判断准确性的影响方式不同;学习次数对学习难易度判断没有显著影响;学习难易度判断中存在练习伴随低估效应。 相似文献

Millikan [2000] has levelled a number of persuasive criticisms against Cummins's [1996] theory of mental representation. In this paper, I pave a middle path in the debate between Cummins [2000] and Millikan [2000] to answer two questions. (1) How are representations applied to targets? (2) How is the content of a representation determined? The result is a new theory of mental representation, which I call narrow structuralism. 相似文献

A within-participant comparison of simple-to-complex, complex-to-simple, and simultaneous protocols was conducted establishing different sets of three 7-member equivalence classes for 4 undergraduate students. The protocols were implemented under either accuracy-only or accuracy-plus-speed conditions while keeping number of presentations of training and testing trials equal. The results partially support previous reports of differential effects on acquisition, with participants completing more blocks in training under the simultaneous than the complex-to-simple and the simple-to-complex protocols. Across the protocols, however, the number of trials completed to criterion did not vary systematically. More important, response speed and accuracy did not decrease as a function of nodal number, with or without the speed contingency, or under any protocol. The latter results challenge the generality of previous reports of the nodality effect and the notion of "relatedness" of equivalence-class members, and support a reinforcement-contingency, instead of a structural, perspective on equivalence-class formation. 相似文献

采用3×3×2(年龄,材料,性别)三因素混合实验设计,按照学习成绩好、中、差分层随机选取小二、初二、大二学生被试各18名,其中男女各半,利用不同难度的材料,对被试提取自信度准确性的发展进行了考察。被试的判断等级与被试的记忆成绩之间的两点距随年龄而变化。而这种变化在不同难度间有不同的表现。(1)提取自信度准确性从小二到初二发展迅速,表现出显著差异;初二到大二阶段年龄差异不显著。材料难度对不同年级的被试提取自信度判断准确性的影响不同。材料难度越小,提取自信度准确性发展得越早。(2)提取自信度准确性发展的性别差异不显著。 相似文献

In this paper the author explores the theoretical and technical issues relating to taking notes of analytic sessions, using an introspective approach. The paper discusses the lack of a consistent approach to note taking amongst analysts and sets out to demonstrate that systematic note taking can be helpful to the analyst. The author describes his discovery that an initial phase where as much data was recorded as possible did not prove to be reliably helpful in clinical work and initially actively interfered with recall in subsequent sessions. The impact of the nature of the analytic session itself and the focus of the analyst's interest on recall is discussed. The author then describes how he modified his note taking technique to classify information from sessions into four categories which enabled the analyst to select which information to record in notes. The characteristics of memory and its constructive nature are discussed in relation to the problems that arise in making accurate notes of analytic sessions. 相似文献

We report two empirical studies that investigated previously reported benefits of a high accuracy motivation, and thus a high threshold, for children's and adults' event recall and for their ability to resist false suggestions. In the studies, 6-, 7-, and 8-year-olds, as well as adults, were shown a brief video about an event and were later asked unbiased and misleading questions about it. In Study 1, participants were either (a) given the typical accuracy instructions (including the option to answer with "I don't know"), (b) reminded of the accuracy instructions during the interview, or (c) immediately given feedback and a token for every correct answer. The results showed that the reminders were ineffective in stimulating strategic control behavior in children, independent of age. In Study 2, the confounding effects of feedback and incentives were disentangled by contrasting (a) free report, (b) feedback only, (c) incentives only, and (d) feedback plus incentives. Analyses on recall performance and suggestibility revealed that both feedback and incentives are necessary to increase children's accurate memory reports. 相似文献

Van Breukelen offers a promising method for modeling both response speed and response accuracy. However, the underlying conception of both dependent measures is somewhat flawed, leading the author to conclude that the approach possesses limitations that, under revised assumptions, may not hold. The central misconception, and a set of related misconceptions, is addressed, and it is suggested that this approach holds a good deal of promise for application in the perceptual and cognitive sciences. 相似文献

Near the end of life, individuals often become too ill to express their wishes about the use of life-sustaining medical treatment. Instructional advance directives (i.e., livings wills) are widely advocated as a solution to this problem based on the assumption that healthy people can predict the types of medical treatment they will want to receive if they become seriously ill. In this paper, we review a large body of research from the psychological and medical literatures that challenges this assumption. This research demonstrates that across a wide variety of decision contexts people show limited ability to predict their affective and behavioral reactions to future situations. We outline several ways that policy and law regarding the use of advance directives could be informed by this research, and suggest a number of issues involved in advance medical decision making that could benefit from additional empirical and conceptual attention.

Four experiments examined how accurately participants can report the times of their own decisions. Within an auditory reaction time (RT) task, participants reported the time at which (a) the tone was presented, (b) they decided on the response, or (c) the response key was pressed. Decision time reports were checked for plausibility against the actual RTs, and we compared the effects of experimental manipulations on these two measures to see whether the reported decision times showed appropriate effects. In addition, we estimated the amount of error associated with individual decision time reports by checking how often participants’ decision time reports were implausibly early (i.e., before stimulus onset) or late (i.e., after response), and by using several quantitative models. Overall, the results suggest that decision time reports are not very accurate but they may be usable for some purposes. 相似文献
