小学教师对学生注意问题的知觉准确性研究

本研究以24名小学教师和98名小学生为研究对象,采用访谈法与测验法探讨了小学教师对学生注意问题的知觉准确性及其影响因素。结果表明:(1)从总体上看,小学教师对学生注意问题的知觉有着较高的准确性;(2)小学教师对学生注意问题的知觉准确性水平随教龄和职称的增高而呈下降趋势;(3)小学教师对学生注意问题的知觉准确性水平与其条件性知识掌握情况表现正相关;(4)小学教师对学生注意问题的知觉准确性与其所教年级无关。     

条件推理与概率判断

选取6个具体内容的条件命题和1个纯形式的条件命题作为实验材料,以大学生为被试,深入探讨了条件推理的认知加工机制。结果发现,大学生被试对四种推理形式的认可程度主要与范畴前提的概率值成正比,条件推理似乎是一种基于概率判断的直觉而高效的认知加工过程,进一步证实了Oaksford（2000）以及Evans（2003）等人的观点。     

狭义情绪的神经—心理机制

在新近人们对情绪神经机制的探索中,很多研究成果都在表明,在通常概念下的人的情绪感受中,不仅有那种含有喜厌态度的更严格意义上的情绪成分,还有直接来自各种内外感官上的认知性感知觉成分。本文的目的是运用新近的情绪心理学研究成果,仅以情绪内在体验中的含有喜厌态度的心理成分作为情绪的心理实体,对其的神经—心理机制进行一些尝试性的解释,以期使通常概念情绪感受中的情绪成分和感觉成分更具可辨性。

Factors affecting conditional discrimination learning by pigeons

In Experiment 1 (within subjects) and Experiment 2 (between subjects) it was shown that the sequential training of pigeons on a color discrimination and then on its reversal, each in a different floor-tilt/texture context, failed to produce conditional control of discriminative performance by those contexts. Daily alternation between the two problems (with correlated contexts) was successful, however. In each of these experiments conditional control was better reflected in generalization test performance in extinction than during sessions of training with reinforcement.     

Correspondence as conditional stimulus control: insights from experiments with pigeons.

Correspondence between saying and doing, typically studied in young children and individuals with developmental disabilities, was examined as an instance of conditional stimulus control. In Experiment 1, 3 pigeons were exposed to a two‐component repeated‐trials procedure. In the first—sample or say—component, two response keys transilluminated by different colored lights were presented and the pigeon pecked one of the keys. After 1 s of darkness in the chamber, the second—choice or do—component was presented, in which the two keys again were transilluminated, one by the color selected in the first component and the second by another color. Selecting the color that matched that selected in the say component resulted in access to food. Selecting the other color produced a blackout of the chamber. After an intertrial interval (ITI), the next say component was programmed, and the procedure was repeated. Correspondence remained at chance levels through several manipulations of ITI duration and sample response requirement. When a correction procedure was added such that only the originally selected sample stimulus was re‐presented until a correct choice response occurred, reliable correspondence developed in 2 pigeons. This correspondence was eliminated by making reinforcement independent of correspondence and subsequently was reestablished when reinforcement again depended on correspondence. In Experiment 2, 3 other pigeons rapidly acquired correspondence under the final procedure used in Experiment 1. Increasing the time interval between the say and do components diminished correspondence. The results of the two experiments suggest how correspondence may be considered an instance of conditional stimulus control and that it is possible to construct a homologue of human say‐do correspondence with pigeons.     

Priming effect in affirmative complex conditional connectives

We report the results of an experiment that examined the mental representations underlying the comprehension of complex conditional connectives (such as “A, on condition that B”) and the conditional if (such as “A, if B”). The mental representations during the comprehension stage were analysed using a “priming methodology”. The experiment showed that participants read the possibility “A and not-B” faster when it was primed by “A, if B” than when it was primed by “A, on condition that B”. The finding suggests that people understand the sentence “A, on condition that B” as biconditional; other possibilities (“A and B”, “not-A and B”, “not-A and not-B”) were primed equally by both connectives. We discuss the implications of this for current theories of reasoning.     

Combined Audience and Video Feedback With Cognitive Review Improves State Anxiety and Self-Perceptions During Speech Tasks in Socially Anxious Individuals

This study investigated the effects of combined audience feedback with video feedback plus cognitive preparation, and cognitive review (enabling deeper processing of feedback) on state anxiety and self-perceptions including perception of performance and perceived probability of negative evaluation in socially anxious individuals during a speech performance. One hundred and forty socially anxious students were randomly assigned to four conditions: Cognitive Preparation + Video Feedback + Audience Feedback + Cognitive Review (CP + VF + AF + CR), Cognitive Preparation + Video Feedback + Cognitive Review (CP + VF + CR), Cognitive Preparation + Video Feedback only (CP + VF), and Control. They were asked to deliver two impromptu speeches that were evaluated by confederates. Participants’ levels of anxiety and self-perceptions pertaining to the speech task were assessed before and after feedback, and after the second speech. Compared to participants in the other conditions, participants in the CP + VF + AF + CR condition reported a significant decrease in their state anxiety and perceived probability of negative evaluation scores, and a significant increase in their positive perception of speech performance from before to after the feedback. These effects generalized to the second speech. Our results suggest that adding audience feedback to video feedback plus cognitive preparation and cognitive review may improve the effects of existing video feedback procedures in reducing anxiety symptoms and distorted self-representations in socially anxious individuals.     

不同类型反馈对儿童学习效果的影响及性别差异

儿童阶段是对外部反馈最敏感的阶段。以往研究发现,不同类型反馈（积极/消极反馈）和不同性质的强化物（物质/社会性强化）对儿童学习效果存在交互作用,并且对不同性别儿童的影响有所不同。本研究通过两个实验,采用联结学习范式以考察不同类型反馈对8~10岁儿童学习效果的影响。首先考察了积极反馈和消极反馈对儿童学习效果的影响,进而在积极、消极反馈的基础上加入了物质、社会性强化物,探究物质、社会性强化条件下积极、消极反馈对儿童学习效果影响的性别差异。结果表明,对于8~10岁儿童来说,消极反馈比积极反馈对儿童学习效果的影响更大。并且,物质、社会性强化物对儿童反馈学习效果的影响存在性别差异,对于男孩来说,在物质性强化条件下,消极反馈更能促进其学习;而对于女孩来说,在社会性强化物下,消极反馈更能促进她们的学习。该研究为如何运用反馈促进儿童学习提供了实证依据。
