关键字母法对中国学习不良儿童英语词汇记忆的作用

关键字母法是将西方世界著名的关键词方法的原理同汉字特点相结合的产物。以39名普通初一学生为控制组,以21名学习不良的小学五年级学生为实验组,以64个罕见的英文单词作为记忆测验材料,考察了关键字母法对于中国儿童英语词汇记忆的作用。该研究最重要的结果是,在关键字母法干预实验前,作为实验组的小学五年级被试的英语词汇记忆成绩显著地低于作为控制组的初一学生的记忆成绩,然而,在关键字母法干预实验后,前后两者的英语词汇记忆成绩不存在显著的差异。     

颜色词与颜色认知的关系——基于民族心理学的研究视角

颜色词与颜色认知的关系是语言影响认知的重要领域.不同民族之间存在着语言和文化的差异.对于颜色词与颜色认知的关系,一直就存在着普遍进化理论和语言相对论的争论.既往研究通过哲学思辨、命名和计算、颜色分类、颜色记忆和颜色搜索等多种范式对颜色词与颜色认知的关系进行了卓有成效的探讨,使该领域的研究呈现出蓬勃发展的局面.     

“上下意象图式”对汉语成语感情色彩加工的影响

通过两个实验,考察了＂上下意象图式＂对汉语成语感情色彩加工的影响。实验一发现,成语感情色彩加工存在＂隐喻一致效应＂,褒义的成语呈现在屏幕上方加工得更快,贬义的成语呈现在屏幕下方加工得更快、更准。实验二消除了具体空间信息的影响,发现仅有抽象符号水平的联结,＂上＂、＂下＂概念不能影响汉语成语感情色彩的加工。研究结果支持隐喻理论和具身认知观。     

语言对知觉的影响—— 来自颜色范畴知觉研究的证据

介绍了近年来语言和颜色范畴知觉关系研究的新进展, 特别是颜色范畴知觉效应的偏侧化、婴幼儿颜色范畴知觉的特点等。同时指出了今后需要进一步研究的问题, 如颜色范畴知觉效应偏侧化与语言的关系、右脑语言优势者颜色范畴知觉的特点、颜色加工脑区和语言加工脑区之间的关系以及婴幼儿颜色范畴知觉特点的追踪研究等。     

颜色凸显条件下基于工作记忆内容的视觉注意

采用记忆任务与视觉搜索任务相结合的实验范式,通过操纵背景颜色与刺激颜色,考察了工作记忆内容对视觉注意的引导是否存在强自动性。实验一通过操作背景颜色以突显记忆项目,结果发现即使工作记忆内容在匹配分心物的情况下仍然自动地捕获视觉注意。实验二通过操作背景颜色以突显目标项目,结果发现工作记忆内容对视觉注意的自动引导作用消失。说明了与工作记忆内容匹配的刺激能够自动地引导视觉注意,但是这种引导并非完全自动化,具有一定的条件性。     

“解释法”样例对小学生学习新运算规则的促进

为证实“解释法”样例设计的促进作用,实验考察了4年级小学生学习“解释”样例与普通样例、“解释”样例和“解释-标记”与普通样例的迁移效果。结果表明：（1）用“解释”样例学习分数加减运算规则的近迁移成绩明显优于普通样例,但远迁移成绩无显著差异;（2）用“解释-标记”样例学习分数乘除法运算规则的远迁移成绩明显优于“解释”样例和普通样例,但近迁移成绩差异不显著,学习“解释”样例的远迁移效果均明显优于普通样例;（3）学习“解释法”设计的比例运算样例,其远、近迁移成绩均明显优于普通样例的迁移成绩,并受被试先备知识的影响。     

文化差异影响彝、白、纳西和汉族大学生对黑白的认知

以彝族、白族、纳西族和汉族的大学生为被试,采用颜色相似性判断和颜色再认任务,考察了彝族、白族、纳西族和汉族的大学生对于黑色和白色的认知,意在探究不同民族的黑、白文化是否影响人们对黑、白颜色的认知。结果发现：⑴彝族、白族、纳西族和汉族的黑、白文化影响四个民族的大学生对于黑色和白色的认知;⑵语言和文化对于颜色认知的影响包括间接效应和直接效应。整个研究表明,语言和文化对颜色认知有重要影响     

Conditioned reinforcement value and resistance to change

Three experiments examined the effects of conditioned reinforcement value and primary reinforcement rate on resistance to change using a multiple schedule of observing-response procedures with pigeons. In the absence of observing responses in both components, unsignaled periods of variable-interval (VI) schedule food reinforcement alternated with extinction. Observing responses in both components intermittently produced 15 s of a stimulus associated with the VI schedule (i.e., S+). In the first experiment, a lower-valued conditioned reinforcer and a higher rate of primary reinforcement were arranged in one component by adding response-independent food deliveries uncorrelated with S+. In the second experiment, one component arranged a lower valued conditioned reinforcer but a higher rate of primary reinforcement by increasing the probability of VI schedule periods relative to extinction periods. In the third experiment, the two observing-response components provided similar rates of primary reinforcement but arranged different valued conditioned reinforcers. Across the three experiments, observing-response rates were typically higher in the component associated with the higher valued conditioned reinforcer. Resistance to change was not affected by conditioned reinforcement value, but was an orderly function of the rate of primary reinforcement obtained in the two components. One interpretation of these results is that S+ value does not affect response strength and that S+ deliveries increase response rates through a mechanism other than reinforcement. Alternatively, because resistance to change depends on the discriminative stimulus-reinforcer relation, the failure of S+ value to impact resistance to change could have resulted from a lack of transfer of S+ value to the broader discriminative context.     

CONCURRENT RESURGENCE AND BEHAVIORAL HISTORY

The contribution of past experiences to concurrent resurgence was investigated in three experiments. In Experiment 1, resurgence was related to the length of reinforcement history as well as the reinforcement schedule that previously maintained responding. Specifically, more resurgence occurred when key pecks had been reinforced on a variable-interval 1-min schedule than a variable-interval 6-min schedule, but this effect may have been due either to the differential reinforcement rates or differential response rates under the two schedules. When reinforcement rates were similar (Experiment 2), there was more resurgence of high-rate than low-rate responding. When response rates were similar (Experiment 3), resurgence was not related systematically to prior reinforcement rates. Taken together, these three experimental tests of concurrent resurgence illustrate that prior response rates are better predictors of resurgence than are prior reinforcement rates.     

预览搜索中基于颜色的两种自上而下加工

预览搜索（preview search）研究是近几年来注意选择研究领域新的热点。本研究将预览搜索任务和探测任务相结合,通过两个实验证明了预览搜索中存在基于颜色的自上而下加工。在每次实验中,先出现预览项目,然后让被试根据有无提示音完成搜索任务或探测任务。在实验一中,探测点的颜色为旧项目同色和无关色两种;在实验二中,探测点的颜色为新项目同色和无关色两种。结果发现,旧项目同色的探测子的反应时长于无关色反应时,而新项目同色的探测子的反应时短于无关色反应时。笔者认为这是由于在预览阶段,可能存在两种自上而下加工,一种是主要基于旧项目颜色的抑制定势,另一种是基于靶子颜色的预期定势。这两种自上而下的调控机制可以解释预览效应的原因,同时利用颜色等特征的格式塔组织也在预览搜索中起着重要的作用
