汉字词形、音、义信息在色词干扰中的自动激活

采用色词于扰的研究范式,考察了汉字词形、音、义信息的自动激活对色词颜色命名的影响。结果表明,颜色词的同形假字、同音词和语义上有联系的词都对色词的颜色命名产生了影响。这种影响来自无意识的平行加工的过程,说明汉字词的形、音、义信息都存在自动激活的现象。     

反馈类型和反馈时间对动作技能获得的影响

基于简单直线运动任务和复杂曲线追踪任务,在运动技能获得阶段考察不同反馈类型和反馈时间对操作绩效的影响。结果发现,在复杂曲线轨迹追踪任务中,接受运动轨迹反馈的被试组比接受偏差数值反馈组的成绩更好;即时反馈和延迟反馈组的操作绩效间没有显著差异。在简单直线运动任务中,提供落点偏差的图形反馈组成绩始终优于提供“近/远”信息的文本反馈组;在练习初期,即时反馈组成绩更好。说明,反馈信息的具体-抽象程度影响被试运动技能获得,提供具体直观的轨迹/图形反馈利于运动技能获得;反馈时间对运动技能的影响因任务难度而异。     

汉字识别中的同音字效应:语音影响字形加工的证据

两个实验考察汉字识别中语音对字形加工产生的影响。实验一采用视觉呈现材料的词汇判断法,没有发现如同英语研究中的同音字效应,实验二采用视、听跨通道的实验范式,首先呈现汉字的语音,然后进行视觉的词汇判断,结果发现,当出现的汉字为低频字时,其同音字越多,词汇判断的时间越长。这说明汉字的识别过程中,语音对低频字字形的加工有一定影响。     

反馈干预对绩效的影响研究

反馈干预是由外部动因提供的关于个体任务操作或过去行为的信息活动,它有反馈对象、反馈效价和反馈提供方式三个维度。研究结果表明反馈效价、反馈提供方式对绩效的影响具有主效应,且两者的之间交互作用对绩效也存在主效应。积极反馈效价、信息型提供方式有助于提高个体的绩效水平。     

义符熟悉性对高频形声字词汇通达的影响

采用启动词汇判断范式,考察义符熟悉性对高频汉字形声字认知的影响。结果表明,义符加工与整字加工存在动态的交互作用。在加工早期,高频汉字形声字的整字语义已经激活,但此时义符的语义并未激活。高熟悉性义符的词形启动比低熟悉性义符早。随着SOA增长,高、低熟悉性义符的语义都出现激活。到了加工晚期,汉字形声字整字的语义激活仍然显著,但义符的语义激活消失,表明字词认知的整合过程已经完成。这一结果支持汉字认知中整字加工和部件加工相结合的观点     

生理反馈对音乐情绪反应的影响

采用主观情绪自评和生理指标考察不同生理反馈在音乐情绪诱发中的作用.结果 发现:(1)真实反馈实验中,有生理反馈时主观情绪感受、呼吸和心率高于无生理反馈条件.(2)虚拟反馈实验中,有生理反馈时主观情绪感受和心率高于无生理反馈条件;在积极音乐上,反馈条件下诱发的积极情绪效应更大.以上两个实验均表明生理反馈能增强积极音乐情绪...     

反馈干预对学习判断的影响

将反馈干预作为外部线索引入元记忆研究,采用重复学习任务,在第一轮次学习-测验之后插入反馈干预,用两个实验分别考查任务反馈和能力反馈两种形式下的反馈效价对第二轮次即时学习判断的影响.结果表明：①在学习过程中,学习者会进行自我监测;②在任务反馈形式下,反馈信息与自我监测信息冲突,导致反馈干预对元认知监测和认知过程没有影响;③在能力反馈形式下,反馈信息与自我监测信息的冲突消失,结果消极反馈影响了元认知监测.由此得出结论：只有在不与自我监测信息冲突的情况下,反馈干预才对学习判断产生影响.此外,在有反馈干预的情况下,两个实验中都出现了显著的练习伴随低估效应.     

汉语合成词的整词词形表征

关于汉语合成词的表征方式历来存在争论:是分解式表征还是整词式表征?文章阐述了整词式表征存在的心理可能性和实验证据,并指出该表征由语音、语义和字形三种不可分割的表征形式构成.前人研究表明,合成词在语音和语义层面可能拥有整词表征,但目前鲜有研究探讨整词词形表征存在的合理性.据此,文章试图寻找考察整词词形表征的研究范式及可能影响汉语合成词词形表征特点的语言因素.     

上级反馈对员工行为的影响

采用2×2(反馈方式、反馈对象)两因素组间实验设计,选取303名被试考察了上级反馈对员工积极整合行为倾向、冲突行为倾向和中立行为倾向的影响,以及个人主义-集体主义倾向对这种影响的调节作用。结果表明,Singelis、Triandis等人有关个人主义、集体主义的理论框架基本适合中国被试,个体的个人主义、集体主义倾向对反馈的效果起到一定的调节作用。领导的反馈方式、反馈针对的对象对员工的行为主效应都显著,上级的表扬会增加员工的中立行为倾向,针对个人的反馈会引起较强的冲突行为倾向。     

反馈间隔影响反馈加工：整合行为和电生理研究的视角

反馈在现实生活中扮演着重要角色, 通过反馈信息进行学习是人类获取知识和技能的有效手段。反馈间隔是指个体行为发生到反馈刺激呈现之间的时间间隔。在反馈加工过程中, 反馈间隔是一个重要影响因素, 但反馈间隔影响反馈加工的研究结果不一。对反馈间隔影响反馈加工的行为和电生理研究分别做了介绍, 对结果出现差异的原因进行了分析。未来的研究应考虑结合行为研究与电生理研究, 并统一反馈间隔的操作定义。     

Reduced orthographic learning in dyslexic adult readers: Evidence from patterns of letter search

Visual letter search performance was investigated in a group of dyslexic adult readers using a task that required detection of a cued letter target embedded within a random five-letter string. Compared to a group of skilled readers, dyslexic readers were significantly slower at correctly identifying targets located in the first and second string position, illustrating significantly reduced leftward facilitation than is typically observed. Furthermore, compared to skilled readers, dyslexic readers showed reduced sensitivity to positional letter frequency. They failed to exhibit significantly faster response times to correctly detect target letters appearing in the most, compared to least, frequent letter position within five-letter words, and response times correlated with positional letter frequency only for the initial, and not the final, letter position. These results are compatible with the SERIOL (sequential encoding regulated by inputs to oscillations within letter units) model of orthographic processing proposed by Whitney and Cornelissen (2005). Furthermore, they suggest that dyslexic readers are less efficient than skilled readers at learning to extract statistical regularities from orthographic input.     

The Name-Pronunciation Effect: Further Evidence from Chinese

This study examined the Chinese name-pronunciation effect. The easy-to-pronounce and difficult-to-pronounce Chinese names were created using the same characters in order to control for visual perceptual and conceptual fluency. In Experiment 1, participants rated each name in terms of liking, electability as a state leader, income level, and baby name preference. An additional rating of prevalence was used to estimate familiarity. In Experiment 2, participants did not read the name aloud before rating and performed intentional recall and recognition tests. In both experiments, the easy-to-pronounce names were rated higher than difficult-to-pronounce names on liking. This effect generalized to judgments of electability and baby name preference but not to prevalence and income level. There were no differences in memory performances between the two types of names. Results are discussed in terms of the boundary condition of the name-pronunciation effect and the advantage of using Chinese names to study this effect.     

情绪Stroop效应:来自汉字的证据

通过颜色命名和词汇阅读两种作业任务,采用情绪词、中性词两类刺激材料,探索情绪Stroop效应中Stroop加工的特点和机制。结果发现：（1）两种作业任务都发现明显的情绪Stroop效应;（2）两种作业任务中情绪Stroop效应不受情绪词的抽象性影响。它说明情绪stroop效应与经典的Stroop效应是两种独立的现象,前者的加工过程是由于情绪词所产生的情绪威胁而导致反应延迟,而不是经典Stroop效应的选择性注意机制。     

不同编码对听写困难儿童字形记忆的促进效应

听写困难是一种发生率较高的儿童学习障碍现象。实验考察笔画语音编码和动作编码对听写困难儿童字形记忆水平的影响。结果发现, 笔画语音编码对听写困难儿童的字形记忆成绩没有明显影响, 但却明显促进了正常儿童的字形记忆成绩; 与之相对, 动作编码对正常儿童的字形记忆成绩没有明显影响, 但却明显促进了听写困难儿童的字形记忆成绩。上述现象, 既可能源于编码加工阶段, 也可能源于字形表征的提取阶段。     

The Effect of Feedback Schedule Manipulation on Speech Priming Patterns and Reaction Time

Speech priming tasks are frequently used to delineate stages in the speech process such as lexical retrieval and motor programming. These tasks, often measured in reaction time (RT), require fast and accurate responses, reflecting maximized participant performance, to result in robust priming effects. Encouraging speed and accuracy in responding can take many forms, including verbal instructions and feedback, and often involves visually displayed RT feedback. However, it is uncertain how manipulation of the schedule of this RT feedback influences speech RT speed and, ultimately, the priming effect. This experiment examined the effect of visually presented RT feedback schedules on priming patterns in 20 older healthy adults. Results suggested that feedback schedule manipulation had a differential effect on reaction time, depending on the interstimulus interval between the prime and the target, but no effect on response priming patterns.     

汉字部件水平的重复知盲效应

本研究采用不同部件特点的汉字材料考察在汉字部件水平的重复知盲效应。实验1探究在一组刺激序列中,当两个关键刺激R1和R2的相同部件在不同位置时对重复知盲效应的影响。实验1结果表明,不同条件的重复知盲效应存在显著差异,但其中两个关键字中相同部件的位置相同时与部件位置不同时之间的重复知盲效应无显著差异,这表明部件位置对重复知盲现象无显著影响。实验2探究当关键刺激R1和R2为部件包含关系时的重复知盲效应。实验2结果表明,当一个关键刺激为独体字,且是另一个关键刺激的部件时存在重复知盲效应,其效应的大小会受到具有包含关系的两个关键字（合体字和独体字）在刺激序列中出现顺序的影响,当第二个关键刺激为独体字时的重复知盲效应要显著强于第二个关键刺激为合体字条件。研究结论是不同的汉字部件特点会影响重复之盲效应,这表明重复知盲现象很可能发生在在线的知觉加工过程。     

An Analysis of Feedback from a Behavior Analytic Perspective

The present paper presents a systematic analysis from a behavior analytic perspective of procedures termed feedback. Although feedback procedures are widely reported in the discipline of psychology, including in the field of behavior analysis, feedback is neither consistently defined nor analyzed. Feedback is frequently treated as a principle of behavior; however, its effects are rarely analyzed in terms of well-established principles of learning and behavior analysis. On the assumption that effectiveness of feedback procedures would be enhanced when their use is informed by these principles, we sought to provide a conceptually systematic account of feedback effects in terms of operant conditioning principles. In the first comprehensive review of this type, we compare feedback procedures with those of well-defined operant procedures. We also compare the functional relations that have been observed between parameters of consequence delivery and behavior under both feedback and operant procedures. The similarities observed in the preceding analyses suggest that processes revealed in operant conditioning procedures are sufficient to explain the phenomena observed in studies on feedback.     

时间估计任务中的反馈加工和行为调节：来自ERP的证据

本研究采用时间估计任务, 利用高时间分辨率的ERP技术, 试图从时间进程上窥探行为调节的认知神经机制。该时间估计任务提供了指导行为调节的反馈信息有三类：时间估计的准确性、时间估计的不准确方向和不准确程度。行为结果表明, 被试根据前次时间估计的对错、不准确的方向和程度进行相应的调整。脑电成分发现, FRN对于时间估计的对、错敏感, 对时间估计的不准确的方向和程度不敏感, 显示FRN提供了粗略的、需要做出行为调节的早期预警信号; 相反, P300能够区别时间估计上不准确的方向和程度, 结合行为数据, 显示P300反映的是整合不同的信息来更新行为表征, 从而引导被试做出不同方向和不同程度的调节。这些结果表明, 行为调节的认知神经基础可能由两个阶段组成：早期传递需要做出行为调节的预警信号阶段和晚期整合信息来更新行为表征从而指导行为调节的阶段。     

三到六年级汉语儿童英语拼写发展及其与正字法规则意识的关系

本研究对167名三到六年级的汉语儿童进行了英语拼写测验和英语正字法规则意识测验,结果发现:(1)汉语儿童在整个小学时期的英语拼写能力都基本处于字母名称拼写策略阶段,在四年级到五年级期间,其整体拼写水平有较显著提高;(2)汉语小学儿童的英语拼写水平与其正字法规则意识显著相关,四、五、六年级儿童的英语字母可双写位置规则对其英语拼写能力具有显著预测作用。
