预设路径模型及其在认知心理学研究中的应用

预设路径模型(Fixed-links modeling)是在结构方程模型框架下发展出的用于分析心理学实验数据的统计模型。该类模型的主要特征是根据前期理论基础和实验设计,通过预先设定模型中显变量与潜变量之间的因素载荷矩阵实现对显变量方差的拆分。因素载荷矩阵的设定主要基于实验水平与所表征的心理过程之间的关系,选取相应函数来表征不同实验水平之间的变化趋势。该模型在表征工作记忆、注意和学习的内部加工过程及揭示不同认知过程的具体联系中发挥了重要作用。     

儿童注意力与智力关系的研究

儿童的智力与注意力有着密切关系,这引起了许多心理学研究者的注意。有些学者认为注意力是智力的一个组成部分,有些学者认为注意力是非智力因素,但对儿童的认识活动发生很大影响。但是许多研究仅停留在理沦探讨上,缺乏足够的实验研究。本研究的目的是:通过对智力与注意力两者关系的研究,寻找之间的具体关系。     

学业优秀者和学业不良者的倒摄抑制比较 ——从结构化和非结构化角度

以汉字为实验材料,以学业优秀者和学业不良者为被试,探讨学习材料的结构化和非结构化性质对倒摄抑制产生的影响,以及两类学生学习两类材料时的倒摄抑制差异。并通过指导语,逐步揭示结构化材料中的规则,迫使被试采用有效的学习策略,来观察倒摄抑制的变化情况。结果表明:一、与非结构化材料相比,学习结构化材料表现出更好的记忆绩效,但未发现两者对倒摄抑制的不同影响;二、和学优者相比,学业不良者的记忆绩效较差,倒摄抑制值也较大;三、对材料规则的提示会促进学业不良学生的记忆绩效,降低倒摄抑制,但对学习优秀者的影响不大;四、一些汉字识别特征影响倒摄抑制,如当干扰项和目标项构形相同时,会降低倒摄抑制。     

权力层级与团队绩效关系：权力与地位的一致与背离

本研究致力于探讨在权力与地位不一致的背景下, 权力层级与团队绩效研究的分歧。本研究提出权力层级与团队绩效的关系取决于团队的层级一致性——权力与地位的匹配度。具体地, 当层级一致(权力与地位匹配)时, 权力层级促进团队绩效; 当层级不一致(权力与地位不匹配)时, 权力层级抑制团队绩效。本研究结合问卷、实验和二手数据方法来验证假设, 研究1通过对46个大学生创业实践团队的两阶段问卷调查, 发现层级一致性对权力层级与团队绩效的关系具有调节作用。此后, 研究2通过一项涉及64个团队的实验来揭示因果关系, 发现权力争夺在权力层级和层级一致性的交互与团队绩效的关系中起中介作用。最后研究3通过203个观测值的互联网公司二手数据重复验证了层级一致性的调节作用, 并提升了本研究的生态效度。本研究为权力层级的研究做出了一定的贡献, 并为团队管理提供了启示。     

项目反应理论研究中的计算机模拟方法

引言在项目反应理论看来,心理学中的许多研究都要考虑被试的心理特质θ和对项目的反应P(θ)之间的关系,项目反应理论就是从这一角度进行研究的。若用θ表示被试的某种能力,P(θ)表示能力为θ的被试答对某个项目的概率,那么,完全可以假设,随着θ的增加,P(θ)将会提高,但它们之间的关系究竟用何种函数形式来表示比较合适呢?经过仔细的研究,人们     

饥无食寒无衣则乱无治:社会保障感受与不道德行为的关系

从社会心理学的角度探索社会保障感受与不道德行为的关系,及焦虑在其中的作用。用三个实验对假设进行检验,实验1和实验2探索社会保障感受对不道德行为的影响; 实验3则进一步探索焦虑在其中的作用。回归分析表明,社会保障感受可显著预测人们的不道德行为,社会保障感受越低人们的不道德行为越多; 焦虑在其中起中介作用,低社会保障感受会促进焦虑的产生,继而增加不道德行为。研究从社会心理学角度探索并证实了社会保障感受引发不道德行为的微观心理机制,拓宽了社会保障的伦理道德价值研究视域,为未来从社会心理学的角度研究社会保障与伦理道德的关系提供了可资借鉴的思路。     

能力结构研究

对于能力结构的问题,历来众说纷纭。但近年来研究工作出现的一个明显趋势是:许多研究者都采长补短,力图建立起一个综合的能力结构模型。例如詹森(A.R.Jensen)经过分析,把g一元论与g多元论的理沦统一起来;斯腾伯格(R.J.Sternberg)提出智力三重结构理论,这是当代心理学“相互吸收,日趋综合”的特点在能力研究中的反映,也是能力结构研究日趋成熟的一种表现。笔者于1987年在分析总结以往研究成果的基础上,提出了一个能力结构模型。这个模型就能力构成因素的一般性与特殊性两者之间关系的问题,作了总体上的构思。这一构想经过近年来的实验,已     

中学生笔记策略及其干预研究

做笔记(note-taking)是学生在听课和阅读时普遍使用的学习策略,借此可适当记录所学内容以促进记忆和思考,从而有效控制自己的认知过程和对材料信息的加工,有助于发现和建立新旧知识的内在联系,建构对知识的理解。本研究运用调查法、实验法和训练法对中学生的笔记策略进行实证研究。第一,通过自编问卷调查了中学生的笔记策略运用状况并揭示其特点;第二,通过实验研究探索了学生笔记水平与学业成绩的关系,并分析笔记策略运用的影响因素;第三,运用训练法比较了笔记策略辅导的不同方式对学生的影响,探讨学习策略辅导有效性的影响因素。本研究对认知心理学研究的重要领域~学习策略研究以及学校心理辅导的重要工作~学习策略辅导具有一定的启迪作用。     

关于最佳教学设计的研究

最佳教学设计就是在充分了解学生认知过程和个别差异的基础上,制定出符合学生特点有利于能力提高的教学方案和措施。美国心理学家A.M.Melton 认为:“近年来,理论心理学和实验心理学最重要的发展就是承认了需要对刺激和反应的中间过程或机制提出理论见解。现在已不再争论这种中间过程是否存在,是否对行为起控制作用,而是争论这种中间过程的定义属性、相互联系和相互制约了。”于是,认知心理学应运而生,使心理学家得以用认知加工过程的观点来了解能力、学习和教学之间的关系,从而达到改进教学,提高学生能力的目的。传统的能力研究和智力测验曾对教育的发展作出过积极贡献,但是在今天的教育改革面前就显得鞭长莫及了。因为传统的能力研究和智力测验仅仅是初步的研究,不能揭示出智力的本质。早在四十     

志向水平的实验研究

前言一个人期望自己在某方面取得成就的水平,在心理学中称为抱负水平,又叫志向水平,志趣水平。心理学中对志向水平有过许多研究,例如1961年莱切曼(S.J.Lachman)发现,一个人的志向水平随着他实际完成的作业的多少而变化。活动的成功和失败使个体体验到成就感和挫折感,而成就感和挫折感是影响活动继续进行的非常重要的因素。不过,个人活动的成功和失败是一种主观上的体验,因本人的志向水平不同而表现出差异。本研究用实验方法探讨大学生志向水平和活动的成功与失败的关系,并试图对实验结果进行理论的分析。     

The effect of word length in short-term memory: Is rehearsal necessary?

Three experiments investigated the effect of word length on a serial recognition task when rehearsal was prevented by a high presentation rate with no delay between study and test lists. Results showed that lists of short four-phoneme words were better recognized than lists of long six-phoneme words. Moreover, this effect was equivalent to that observed in conditions in which there was a delay between lists, thereby making rehearsal possible in the interval. These findings imply that rehearsal does not play a central role in the origin of the word length effect. An alternative explanation based on differences in the degree of retroactive interference generated by long and short words is proposed.

Elimination of the word length effect by irrelevant sound revisited

The word length effect refers to the tendency for lists of long words to be recalled less well than lists of short words. Theoretical and empirical objections are raised to a recent claim that irrelevant speech eliminates the word length effect (Neath, Suprenant, & LeCompte, 1998). A first experiment using a within-subjects design of adequate power (N = 65) fails to replicate their finding, showing instead that the word length effect is not differentially eliminated by speech as opposed to tones. In a second experiment, the effect of change (repeated vs. changing sounds) is shown to be additive to the effect of word length for both speech and nonspeech. Irrelevant speech and irrelevant tones have comparable effects on lists of short or lists of long words. These results are at variance with the feature model (e.g., Nairne, 1990).     

Retroactive inhibition as a function of the conceptual structure of original and interpolated lists

Subjects learned either a hierarchically structured serial list of concept instances or a list made up of the same words but without structure. These two original lists were followed by one of four interpolated lists varying in number of hierarchical levels and consisting of new instances of the concepts which occurred in the original lists. Recall of the original structured list showed heavy retroactive inhibition, with the magnitude being independent of the number of conceptual levels in the interpolated lists. For the unstructured original list, retroactive inhibition decreased as the number of conceptual levels in the interpolated list increased. Some mechanisms believed involved in producing these outcomes were discussed.     

The role of horizontal categorization in retroactive and proactive interference

Four paired-associate experiments with a total N of 291 participants investigated the effects of horizontal categorization on retroactive and proactive interference. (Exclusively) horizontal categorization means that unique categorical relationships hold across the A-B and A-C stimulus-response pairs of successive word lists (e.g., fruit--pear, river--Thames, in list 1; and fruit--plum, river--Wolga, in list 2). Experiment 1 found no significant amounts of interference with this type of list organization. However, strong interference arose with the same materials when the categorical structure was destroyed in Experiment 2. A third experiment contrasted two alternative explanations for these results, and Experiment 4 replicated the effect of horizontal categorization (vs. no categorical relationship) in a within-participants design. The results of the four experiments largely fit with a response competition explanation proposed by Bower, Thompson-Schill, and Tulving (1994), adapted to the within-participants designs used here. Overall, the present findings add to a body of evidence demonstrating limits to retroactive and proactive interference.     

Coping with disappointing outcomes: Retroactive pessimism and motivated inhibition of counterfactuals

Having failed to achieve a desired goal, people may use retroactive pessimism as a defense mechanism, concluding that chances of success were not too good to begin with. To make this judgment, one must block counterfactual alternatives suggesting that success was, in fact, quite likely. Facing a bitter disappointment, the perceiver is highly motivated to inhibit upward counterfactuals, thus increasing the perceived inevitability of failure and finding solace in the acceptance of inescapable fate. Two experiments explored the hypothesized link between counterfactuals inhibition and retroactive pessimism. In the first experiment, it was found that participants experiencing grave disappointment, following a near miss, judged their chances of achieving their goal less favorably, compared to participants who had missed their goal by far. An analysis on participants’ counterfactual judgments suggested that this effect was mediated by participants’ perceptions of counterfactual events. The second experiment demonstrated that retroactive pessimism and counterfactual inhibition seem to be unique to situations in which the negative outcome resulted from uncontrollable rather than controllable events, thus corroborating the functional characterization of counterfactual thinking as well as the link between retroactive pessimism and disappointment.     

Revisiting an old issue: Retroactive interference as a function of the degree of original and interpolated learning

Prior research has generally shown that the greater the degree of original learning of a list, the greater the amount of retroactive interference that list suffers. In addition, greater learning of interpolated lists produces more retroactive interference. However, in prior research, the degree of learning has typically been confounded with the amount of retrieval practice on the list. Two free-recall experiments are reported in which subjects studied one original list and then 0, 1, 2, 3, or 4 interpolated lists. The degree of original and of interpolated learning was manipulated by varying exposure time. In Experiment 1, where the typical confounding of retrieval practice and degree of interpolated learning was present, greater interpolated learning induced greater retroactive interference, which is consistent with prior research. However, in Experiment 2, where the degree of interpolated learning was manipulated without concomitant variation in retrieval practice, retroactive interference was the same, whether the interpolated lists had been learned well or poorly. Therefore, greater interpolated learning does not increase the amount of retroactive interference. The results also show that the amount of retroactive interference does not depend on the degree of original learning, in agreement with other work on normal forgetting.     

An experimental analysis of memory processing

Rhesus monkeys were trained and tested in visual and auditory list-memory tasks with sequences of four travel pictures or four natural/environmental sounds followed by single test items. Acquisitions of the visual list-memory task are presented. Visual recency (last item) memory diminished with retention delay, and primacy (first item) memory strengthened. Capuchin monkeys, pigeons, and humans showed similar visual-memory changes. Rhesus learned an auditory memory task and showed octave generalization for some lists of notes--tonal, but not atonal, musical passages. In contrast with visual list memory, auditory primacy memory diminished with delay and auditory recency memory strengthened. Manipulations of interitem intervals, list length, and item presentation frequency revealed proactive and retroactive inhibition among items of individual auditory lists. Repeating visual items from prior lists produced interference (on nonmatching tests) revealing how far back memory extended. The possibility of using the interference function to separate familiarity vs. recollective memory processing is discussed.     

Memory for lists of spatial events in the rat

Three experiments are reported in which rats were presented with lists of spatial events or responses in distinct visual contexts, and retention subsequently was measured for the events occuring at each serial position. In Experiments 1 and 2, lists contained different numbers of forced choices on successively presented T-mazes, and memory for each serial position was tested on each trial. In Experiment 3, lists were made up of different numbers of forced entries into randomly ordered arms on the eight-arm radial maze, and memory for one serial position was probed on each trial. All three experiments yielded serial position curves which demonstrated recency effects but no primacy effects. Comparisons of retention for different list lengths within each experiment indicated that retention of shorter lists was equivalent to retention of the final items of longer lists and superior to retention of the initial items on longer lists. This pattern of results indicated that there was no evidence of proactive inhibition in the serial position curves. Analysis of input and output interference effects and the results of control tests suggested that both retroactive inhibition and time-based forgetting processes were responsible for recency effects.     

Permanence and change in memory II. Reproduction of words in sentences

Abstract.— A retroactive interference paradigm was employed for studying qualitative memory changes. Sentences, containing an ambiguous word that was defined differently by succeeding words, were used as stimulus material. Such retroactive definitions of meaning were found to lead to qualitative changes in reproduction. It is suggested that the issue of permanence and change in memory may be related to the choice of lists of independent items or contextual units as stimulus material. A contextual theory of memory, implying the conception of memory in a stream, is advocated.
