Visual and phonological pathways to the lexicon: Evidence from Chinese readers

In this study, we investigated the role of visual and phonological information in lexical access of Chinese characters. Homophonic English words have been the main source of stimuli for word recognition research. However, since these stimuli also often look alike, visual and phonological information may be confounded in reported experiments. In contrast, many homophonic Chinese characters are visually distinct. In addition, visually similar characters often have very different pronunciations. These characteristics allow a more controlled investigation of the roles of visual and phonological information in activation of meaning. In the present study, two types of Chinese characters were used in a semantic categorization paradigm: integrated characters, which contain strokes that are not separable; and compound characters, which contain at least two clearly identifiable components. The results show that the recognition of a Chinese integrated character depends primarily on visual information, whereas the recognition of a Chinese compound character relies on visual, phonological, and semantic information. It is concluded that visual information plays a greater role in Chinese character recognition than has previously been documented.     

Group counseling in a different cultural context: Several primary issues in dealing with Chinese clients

To apply group therapy or counseling, a branch of helping methodology rooted in modern Western psychology, to a culturally different context, such as the Chinese cultural environment, group counselors need to increase their awareness, knowledge, and skills that are compatible with the group climate they encounter. A group counselor needs to understand the general characteristics of the culture. The counselor should use his or her leadership quality to deal appropriately with group clients' psychological dynamics, which bear unique cultural preferences with respect to thinking, feeling, and doing. While many group counseling communication skills from a Western theoretical framework can be helpful and applicable to the Chinese group clientele, some of these skills need to be contextually modified. The counseling goal is to properly integrate Chinese cultural and therapeutic norms into the group process.He also teaches as a Sessional-Instructor in the same department.     

应激对大鼠行为和部分脑区谷氨酸含量的影响

以旷场试验法测定动物在急、慢性躯体性和心理性应激时的行为变化,以快速断头冷冻匀浆法,用ＨＩＴＡＣＨＩ－８３５氨基酸分析仪测定应激各期视皮层、海马、下丘脑、小脑谷氨酸含量。并对正常动物经侧脑室微量注射Ｌ－ＡＰ４后观察行为变化。结果显示,急性应激期动物行为活动增加,慢性应激期减少：应激时,大鼠部分脑区的谷氨酸含量与对照组相比在不同时期呈显著性差异;侧脑室微量注射Ｌ－ＡＰ４提示行为活动减弱可能与脑内Ｇｌｕ系统的活动有关。     

小学优等生与学习不良学生智力特征的比较研究

本研究运用 WISC-CR研究了小学阶段一、三、五年级优生与学习不良儿童在智力水平与智力结构上的异同。研究结果表明 :1优生与学习不良儿童在智力水平上有十分显著的差异 ,优生的平均智商为 1 2 0 .1 ,学习不良儿童的平均智商为 97.4;2优生在操作分量表与语言分量表上的得分比较均匀 ,但学习不良儿童的操作智商显著地优于语言智商 ;3优生与学习不良儿童在智力结构上也不尽相同 ,优生在词汇、积木、类同等分测验上的得分高 ,在算术、背数、排列等分测验上的得分较低 ;学习不良儿童在拼图、译码、填图、词汇等分测验上的得分较高 ,在常识、算术、背数等上的得分较低。     

试评外周神经生理效应的函数之争

大量的神经生理学实验久已证实由刺激引起的外周神经生理效应具有类似于心理物理效应的高度压缩现象。从外周神经纤维中观察到的神经脉冲频率或发生电位是描述这种压缩效应的常用方法。半个多世纪以来一部分研究人员观察到压缩效应遵守刺激强度的线性对数函数,而另一部分研究人员则观察到幂函数。这种传统实验分歧,通过笔者前时建立的刺激一效应方程,得到合理的说明和两者的统一     

小规模群体开放式与封闭式讨论任务的工作特性比较

１４个小组的大学生共６８人参加两种不同的群体工作,其中７组进行开放式问题的讨论,７组进行封闭式问题的讨论。从工作进程、工作模式和工作特点等方面记录群体工作行为：工作进程各阶段所用时间,发言的针对性,发言的连续性,说明问题的方式和深度,群体的意见分歧与支持行为和表达方式。结果表明：封闭式问题需要更多的时间澄清问题并且更多引用例子来阐述观点;讨论开放式问题多采用归纳推理而封闭式问题多采用演绎推理;无论在哪种问题的讨论中,针对个体的发言都显著多于针对整体的发言,而且人们更多地以非言语的方式而不是口头方式表示赞成。本文对以上结果在电视、电话和计算机辅助会议系统设计中的应用作了进一步讨论     

KNOWLEDGE OF THE ORDINAL POSITION OF LIST ITEMS IN RHESUS MONKEYS

Abstract —What is learned during mastery of a serial task: associations between adjacent and remote items, associations between an item and its ordinal position, or both? A dear answer to this question is lacking in the literature on human serial memory because it is difficult to control for a "naive" subject's linguistic competence and extensive experience with serial tasks. In this article, we present evidence that rhesus monkeys encode the ordinal positions of items of an arbitrary list when there is no requirement to do so. First, monkeys learned four nonverbal lists (1–4). each containing four novel items (photographs of natural objects). The monkeys then learned four 4-item lists that were derived exclusively and exhaustively from Lists 1 through 4, one item from each list. On two derived lists, each item s original ordinal position was maintained. Those lists were acquired with virtually no errors. The two remaining derived lists, on which the original ordinal position of each item was changed, were as difficult to learn as novel lists. The immediate acquisition of lists on which ordinal position was maintained shows that knowledge of ordinal position can develop without the benefit of language, extensive list-learning experience, or explicit instruction to encode ordinal information.     

关于先发情绪体验对后发情绪过程的影响的一项实验

本实验试图探讨是否存在着一种先发体验,它的影响能在随后发生的情绪过程中表现出来。实验得到了肯定的结果。它显示为:(1)先发情绪体验若与后发情绪的性质相接近,则对后者起促进作用;若相反,则起抑制作用,(2)激起后发情绪的反应时(RT)与所发生情绪的持续时(DE)二者之间有显著的正相关。     

中文双音节词视觉识别与短时记忆保持量

两个实验探讨了汉语双音节词的使用度、笔画复杂性与发音长短对短时记忆保持量的影响。结果表明发音长度显著不同的词在记忆保持量上无显著差别;使用度和笔画复杂性对短时记忆保持量有显著影响;笔画复杂性不同的词识别时间与其记忆保持量有显著负相关。最后讨论了笔画复杂性的短时记忆量与词的识别阶段的可能关系。     

论数学能力的研究与认知理论的关系

本文对关于数学能力的实质的心理学研究作了历史的回顾,其中包括心理计量学、认知科学和心理学中的认知发展等几个领域的研究工作。文中揭示了在这几个领域的研究中存在着的几个共同问题。作者认为需要假借这些不同的研究领域中的研究方法,创造新的信息加工的方法以揭示数学能力及其发展的实质。
