On the development of more and less

More and less were analyzed into two meaning dimensions, “occurrence” (derived from children's early language) and “quantity,” which were hypothesized to be developmentally related to acts of addition and subtraction. Two experiments tested 2- and 3-yr-old's comprehension of these concepts when initially equal or unequal rows were added to, subtracted from or left static. Addition and subtraction had little effect on Ss′ comprehension of either term. Two-year-old Ss understood more when differences in the number of objects in the array were relatively large, suggesting “many” as an intermediate stage of meaning for more. Three-year-olds understood less first as “smaller in amount,” not as more as others have found. Less was acquired later than more, a difference possibly due to its relatively restricted meaning and use or to its converse perceptual and logical relation to more.     

Conditioning history and the control of human avoidance and escape responding

Inter-subject differences in response rates under free-operant avoidance and escape schedules are commonly obtained from humans. Data are presented which demonstrate that such differences can be controlled experimentally by giving subjects different conditioning histories. Subjects given a fixed-ratio history avoided and/or escaped from “point-loss periods” at higher rates than subjects given a differential-reinforcement-of-low-rates history. History related differences in response rates were maintained during 40 hr of escape responding. For low-rates history subjects, response rates under escape contingencies decreased as the rate of point-loss periods decreased.     

Operant behavior and the galvanic skin potential under DRL schedule

Motor and galvanic skin potential (GSP) activity were investigated during the conditioning, extinction, and reconditioning of motor responses under a differential reinforcement of low rate (DRL) schedule of reinforcement. Interresponse time (IRT) distributions for motor responses during conditioning and reconditioning gradually stabilized at a peak just beyond the minimal IRT required for reinforcement. Few unreinforced motor responses and "bursts" of motor responses were observed during conditioning and reconditioning. Relative to conditioning and reconditioning, extinction effected larger IRTs and smaller GSP amplitudes. GSP amplitudes were greater for unreinforced than for reinforced motor responses during conditioning and reconditioning. However, GSP amplitudes associated with the unreinforced extinction responses were smaller than either the reinforced or unreinforced responses during conditioning and reconditioning.     

Clinical considerations in the conjoint use of the Rorschach and the MMPI

Contemporary clinical and research findings concerning the Rorschach and the Minnesota Multiphasic Personality Inventory (MMPI) indicate that (a) objectivity and subjectivity are relative and not categorical dimensions of these two instruments; (b) apparent contradictions between Rorschach and MMPI results are generative and not invalidating; (c) within limits, false negative findings are not cause for concern in the clinical application of Rorschach and MMPI variables; and (d) differences between the Rorschach and the MMPI in how they are structured and what they measure demonstrate considerable advantage in using them in complementary fashion to support clinical inferences.     

易道辩正

易道是易学思想的精髓或内在精神,其最根本的特征是所谓的“一阴一阳之道”。作为易学结构基元的易卦卦象符号,与阴阳观念具有先天性的亲和力,从而使得阴阳观念有了一个可以符号化表征的形式系统。在汉代,阴阳五行与易学成为一个统一的有机整体。两汉的象数理论试图将易道(天道)完全形式化努力的最终结果是“入于礻几祥”,成为一套牵强附会的繁琐哲学。魏晋以后,诸如“时”、“中”一类具有明显的个人独知默会、参悟修证意义的命题,逐渐成为一阴一阳、生生不息的“易道”最为生动的表征。道之真谛,若以易理言之,就是“自强不息”,“与时偕行”。     

Biopsychology research in China

The early studies on biopsychology in China were classified under the name of physiological psychology and comparative psychology. In 1979 the Division of Physiological Psychology of the Chinese Psychological Society was founded. Fifteen years later, the Brain‐Behavior Research Center was founded at the Institute of Psychology, Chinese Academy of Sciences. The objective of the Center was to establish a multidisciplinary scientific environment for conducting experimental research on the relationship between brain and behaviour as well as the interactions of the mind and body. A wide range of studies in biopsychology has been conducted in China. The most major research areas are: (1) Behavioural and physiological studies of stress: Research work includes the effect of early environment on stressful responses, interactions of behavioural and endocrine responses under stress, effects of emotional stress on immune function, stress and hypertension and the related role of interleukin‐1. (2) Conditioning and immunity: Studies focus on the effects of conditioning in the modulation of bidirectional immune function. Data from different experiments demonstrate that psychological processes are capable of influencing immune function. The neural substrates are also explored. (3) Memory and learning: Studies mostly concentrate on types of memory formation and training stimulus, effect of light exposure and corticosterone on learning and memory, and the role of the hippocampus in learning and memory. (4) Drug addiction: Work mainly focuses on long‐term aspects of addiction, including memory, novelty seeking, motivation‐related models, and the brain mechanisms underlying morphine psychological dependence.     

Measuring lexical diversity in children who stutter: application of vocd

There is growing but equivocal evidence that the language abilities of young children who stutter (CWS) may be depressed when compared to those of their fluent peers. In particular, the lexical skills of CWS have variously been reported to be weaker or stronger than comparison children in a number of recent studies. One source for such disagreement may be the measures used to compute lexical characteristics of these children’s spoken conversations. In this study, we examined the concurrent validity of two measures of lexical diversity in spontaneous language samples, Type-Token Ratio (TTR) and the newly developed utility vocd (Malvern & Richards, 1997), using a standard test of expressive vocabulary as the comparison measure. Findings indicated that vocd values (“D”) correlated well with standardized measures of expressive vocabulary, while TTR values did not. In addition, both the standardized measure and vocd revealed significantly poorer expressive lexical skills of CWS, whereas TTR analyses did not evidence this difference. Results are discussed in relation to the relative strength of vocd over TTR as a method for describing lexical characteristics of the spontaneous language samples of this population.

Educational objectives: The reader will learn about and be able to (1) identify several common measures of conversational vocabulary and the strengths and weaknesses of each, and (2) compare the performance of the young CWS in this study to their normally fluent peers in terms of vocabulary performance on both formal and conversational measures of vocabulary.     

视知觉无意识对局部形状和颜色特征加工的注意调节

研究了视知觉无意识对局部几何特征加工中的整体优势效应.被试为天津师范大学本科生60名.仪器为pentium III高分辨率计算机,程序用E-prime心理实验软件系统编制而成.被试的任务是判断靶图形中央线条的方向或颜色.用MANOVA分析了启动图形对靶图形局部特征加工的启动效应,发现了视知觉对无意识呈现的图形加工具有形状优势效应,启动图形与靶图形的整体形状相同可以抑制对靶图形局部形状特征的判断.当被试的任务变成判断靶线条的颜色或启动图形的边由连通状态变成不连通时,视知觉无意识对启动图形加工的整体优势效应消失.该结果提示整体优势效应很可能与任务涉及的信息通道密切相关,对局部形状特征的注意很可能涉及对周围整体形状信息加工自动抑制的过程.
