恐惧情绪对大鼠学习记忆的影响

通过对４组不同处理背景动物操作条件学习的实验研究,观察强噪音下恐惧情绪对动物学习、记忆的影响以及怎样通过系统脱敏来减少恐惧在其中的作用。结果发现：恐惧组大鼠的操作条件学习具有第一次联系（健盘与食物之间）成功所需时间短、旧技能遗忘快、重新学习次数多和学习成绩差等特征;恐惧组大鼠与学习无关的恐惧行为增多,严重干扰学习的控制加工过程,影响学习任务完成;强噪音脱敏组大鼠学习过程、学习成绩的各项指标与控制组无差异。

NORMAL PEER MODELS AND AUTISTIC CHILDREN'S LEARNING

Present research and legislation regarding mainstreaming autistic children into normal classrooms have raised the importance of studying whether autistic children can benefit from observing normal peer models. The present investigation systematically assessed whether autistic children's learning of discrimination tasks could be improved if they observed normal children perform the tasks correctly. In the context of a multiple baseline design, four autistic children worked on five discrimination tasks that their teachers reported were posing difficulty. Throughout the baseline condition the children evidenced very low levels of correct responding on all five tasks. In the subsequent treatment condition, when normal peers modeled correct responses, the autistic children's correct responding increased dramatically. In each case, the peer modeling procedure produced rapid achievement of the acquisition criterion which was maintained after the peer models were removed. These results are discussed in relation to issues concerning observational learning and in relation to the implications for mainstreaming autistic children into normal classrooms.     

JUDGMENTS OF SLANT ON THE BASIS OF FORESHORTENING

By analogy with Stavrianos' (1945) finding for linear perspective, it was proposed that the effectiveness of foreshortening as a slant cue would increase as a function of visual angle. Surfaces of vertical lines slanted around a vertical axis were monocularly viewed at three horizontal visual angles and four angles of slant. An adjustment method was used to record apparent slant. An analysis of variance showed significant F ratios for visual angle and angle of slant thus supporting the hypothesis that increasing visual angle increases the effectiveness of slant judgments. However, subjects' verbal reports indicated that slant may not be perceived when only foreshortening is available as a cue.     

论班图拉观察学习理论的特征及其历史地位

该文从以下三个方面分析了班图拉观察学习理论的特征：（１）强化与认知的结合,（２）行为主义的建构论,（３）交互决定论。作者认为,班图拉对心理学的杰出贡献是他发掘了观察学习这一前人所忽视的学习形式,给了观察学习以应有的地位。作者认为,班图拉在其观察学习的研究中,注重社会因素的影响。以认知的术语阐述观察学习的过程与作用,且注重以人为被试的实验,因而对学习心理学的发展产生重要影响。     

CONCEPTUAL MODELS OF LECTURE LEARNING: GUIDING METAPHORS AND MODEL-APPROPRIATE NOTETAKING PRACTICES

The metaphors that college students use to describe lecture learning may reflect conceptual models that direct, organize, and constrain the nature of the notetaking practices they prefer to use. Specific notetaking practices that would be dictated by the metaphors of "Sponge," "Tape Recorder," "Stenographer," "Code Breaker," "Reporter," and "Explorer" were rated as to frequency of use by 84 college students in an introductory psychology class. Subsequent ratings of the adequacy of each metaphor by these students were used to predict preferences for metaphor-appropriate notetaking practices in individual stepwise regression analyses. The perceived quality of a notetaking metaphor was predictive of the metaphor-appropriate notetaking practices reported by students for every metaphor except the Explorer metaphor. The discussion focuses on the role that students' conceptual models of lecture learning might play in facilitating or hindering efforts to improve their notetaking practices. The importance of assessing conceptual models as well as specific behavioral practices in the diagnosis of lecture-learning difficulties and the evaluation of training interventions is also considered.     

智力和元认知技能在发现学习中的作用:任务复杂性的影响

采用自编的计算机模拟发现学习任务,以49名大学生为被试,探讨了在简单和复杂发现学习任务中,智力、元认知技能和学习成绩三者之间的关系。结果发现:在简单任务中,三者关系基本符合混合模型;进行过多的元认知活动,并不能提高学习效果。在复杂任务中,智力对学习成绩起主要预测作用。随着任务复杂性的增加,智力对学习的影响也随之变化,符合难度阈限理论的假设。任务复杂性不同时,智力、元认知技能和发现学习成绩之间的关系也不同,在一定程度上验证了难度阈限扩展理论。     

IMPACT OF THE IMPLEMENTATION OF THE TEACHING/LEARNING CYCLE ON TEACHER DECISION-MAKING AND EMERGENT READERS

No topic is on the minds of the general public, federal and state legislatures, parents, and educators more than the issue of establishing and maintaining school programs that are consistent in their ability to produce competent readers. Teachers, administrators, and teacher preparation programs are admonished to change programs, resources, monitoring procedures - whatever it takes to bring about this reformation of student reading achievement. Topics under investigation include effective models, methods, and strategies of instruction; essential teacher knowledge; teacher decision-making; and professional development of in-service and pre-service teachers. From this body of research the terms "balanced literacy" and "engaged literacy" have emerged. These terms are defined as emphasizing instruction on identified student need and including skills development as well as experience in a variety of texts. The teaching/learning cycle, a model for evaluating student reading behaviors and planning focused instruction, providesa foundation for the development of essential teacher knowledge and skills. As teachers articulate their understanding of the reading process, the characteristics of the learner, and the supports and challenges offered in text and teaching approaches, their practice is changed to make it more congruent with these stated beliefs. When teacher instructional practice is aligned with clear understandings and beliefs, student achievement increases. This study explored how knowledge and use of the teaching/learning cycle in beginning reading instruction impacts teacher decision-making and student achievement. While investigating teachers' knowledge and use of the teaching/learning cycle, two research questions focused on how student learning was affected and the impact of the changes on student/teacher interactions.     

THE PERILS OF PARTICIPATION: EFFECTS OF CHOICE OF TRAINING ON TRAINEE MOTIVATION AND LEARNING

This study presents an empirical test of the effects of trainee choice of training on subsequent motivation and learning. 207 trainees were randomly assigned to one of three conditions: (a) no choice of training; (b) choice of training–but choice not received; (c) choice of training–with choice received. A pilot study was used to create a unique training context whereby trainees could be differentiated on the three conditions of choice, while all ultimately received the identical training module. Results indicated that, after controlling for cognitive ability, those trainees having a choice of training did have greater motivation to learn, provided they were ultimately given the training of their choice. On the other hand, trainees allowed to choose but whose choice was not the training module subsequently delivered were less motivated and learned less than those not asked to participate in the choice of training at all. These findings suggest that, in an organizational training context, there may be some "perils of participation." Implications for future research and practice are discussed.     

ON THE SIGN OF SLOPE IN THE LEARNING OF LINEAR FUNCTIONS

Three groups of subjects were presented with pairs of values ( E and S ) of three different linear functions E = a+bS. In a test phase they had to indicate the E -values that corresponded to the S -values. The values were represented as distances marked on straight lines. Two groups, one a control group, had a positive slope, the third group a negative. The squared sum of the S-E differences was kept constant. All groups had roughly the same performance as measured by the squared sum of deviations from empirical and correct E -values. The learning curves indicated, however, that some learning had taken place in the group with the negative slope. It was concluded that a principle rather than a function was learned.
