Evidence for two types of spatial representations: hemispheric specialization for categorical and coordinate relations

Analyses of human object recognition abilities led to the hypothesis that 2 kinds of spatial relation representations are used in human vision. Evidence for the distinction between abstract categorical spatial relation representations and specific coordinate spatial relation representations was provided in 4 experiments. These results indicate that Ss make categorical judgments--on/off, left/right, and above/below--faster when stimuli are initially presented to the left cerebral hemisphere, whereas they make evaluations of distance--in relation to 2 mm, 3 mm, or 1 in. (2.54 cm)--faster when stimuli are initially presented to the right cerebral hemisphere. In addition, there was evidence that categorical representations developed with practice.     

Intelligence and changes in regional cerebral glucose metabolic rate following learning

Positron emission tomography (PET) studies of brain glucose metabolic rate (GMR) in normal volunteers report inverse correlations between GMR and scores on the Raven's Advanced Progressive Matrices (RAPM) and verbal fluency. A new study in eight normal men reports widespread significant GMR decreases following learning a complex task (the computer game “Tetris”). The purpose of this study is to ascertain the correlations between GMR changes following learning “Tetris” and psychometric intelligence scores (RAPM and WAIS-R) to determine whether high-ability subjects show the largest GMR decreases, as predicted by a brain efficiency hypothesis. This hypothesis is supported with significant correlations between the magnitude of GMR change and intelligence scores in many brain areas that changed with learning. Some implications for the role of attention, memory, and speed of processing are discussed in view of the specific brain areas involved.     

Sex and age difference in adolescents' value judgements of historically important events: theory, stereotypes and data

The extent to which younger and older adolescents differed in their value judgments of historically important events was examined. Subjects were asked to list the ten most important events that happened in or to the U.S. since 1990. The subjects' choices were analyzed as a function of sex, age, political and religious orientation, and family size. In addition, 100 undergraduates were asked to serve as judges and predict which categories would be cited more frequently by males and which by females. Results indicated that the judges' predictions did not match the data. Age was a much better predictor of value judgments than sex. Further, several additional differences in value judgments were revealed that would have been missed had only the variables of sex and age been included in the analyses.     

Report on Shanghai norms for the Chinese translation of the Wechsler Intelligence Scale for Children-Revised

The Chinese translation of the Wechsler Intelligence Scale for Children--Revised (WISC-RC) was administered to 660 children (ages 6 through 16 yr.) in the city of Shanghai. The obtained norms represent children's intelligence levels in big cities where the economic and cultural development is advanced. The norms are reported as "Scaled Score Equivalents of Raw Scores" for each age group and as "IQ Equivalents of Sums of Scaled Scores." The reliability and validity of the norms indicate that the WISC-R is suitable for use with school-age children in China. The difference between the results for our Shanghai sample (WISC-RCs) and a USA sample (WISC-R) is also discussed.     

心算乘法对脑干听觉电反应的影响

本文对31名听力正常的健康人作了脑干听觉电反应(BSR)描记。21人在记录过程中让其心算乘法,其中16人还令其注意听刺激短声并概算其触发次数。观察到21名心算者的BSR中16人的BSRⅠ波振幅比安静时的减小,20人的BSR出现了一阳性大波,未观察到Ⅰ波振幅增大的。在听短声的16人中未见出现Ⅰ波振幅减小者,且其中4人反而出现了Ⅰ波振幅相对增大,结果表明,心算乘法对BSR有一定影响,分析认为一种是对感受器的负反馈控制,另一种是正反馈控制,而且前者占优势。     

Do Parents and Overweight,Treatment-Seeking Youth Provide Similar Ratings of Youths’ Psychosocial Functioning and Fatigue?

Patterns of agreement between parent and child ratings of psychosocial functioning and fatigue in children with obesity were examined. Analyses demonstrated moderate agreement for social anxiety in elementary children and small agreement for social anxiety in adolescents. Results of analyses of overall quality of life revealed small agreement in children under the age of 8, large agreement in children ages 8–12, and moderate agreement in adolescents ages 13–18. Overall ratings of fatigue demonstrated moderate agreement both in elementary children and in adolescents. A meaningful relationship was found between each factor measured by a parent and a child. Patterns which were unexpected given the existing literature were found; possible hypotheses explaining these patterns are presented; and the need for further research is highlighted.     

对15种测验等值方法的比较研究

此项研究通过试验方法对４种基于经典测验理论的等值方法和１１种基于项目反应理论的等值方法进行了比较研究。研究数据为ＨＳＫ正式考试的数据,研究采用了较为可靠的检验标准。研究结果表明,在有些情况下,进行等值处理并非是最好的选择;在题库建设中,某些ＩＲＴ方法是可行的;至少对于ＨＳＫ数据,不论是单、双、三参数,不论是ｍｓ方法和ｍｍ方法,ＩＲＴ参数转换等值方法的误差都较大,均不足取。     

Young children's reports of when learning occurred

This study investigated young children's reports of when learning occurred. A total of 96 4-, 5-, and 6-year-olds were recruited from suburban preschools and elementary schools. The children learned an animal fact and a body movement. A week later, children learned another animal fact and another body movement and then answered questions about when the different learning events occurred. Responses of children who responded correctly to control questions about time supported the hypothesis that temporal distance questions would elicit more correct responses than would temporal location questions. Partial support was also found for the hypothesis that behavior learning would generate more correct reports than would fact learning. Implications for characterizations of children's developing understanding of knowledge and for applications of those characterizations in education and eyewitness testimony are discussed.     

不一致性重读对口语语篇加工中信息激活水平的影响

利用跨通道词汇再认任务,探索了口语临场加工过程中,不一致性重读对新信息以及它所标示的旧信息在语篇表征中激活的影响。结果表明：与控制条件相比,不一致性重读虽然提高了旧信息在语篇表征中的激活水平,但是同时抑制了新信息的激活;这一促进和抑制作用在关键词汇后的500 ms就已出现。从而说明,对于相对重要的新信息,不一致性重读会阻碍语篇的理解,并且会影响到语篇的临场加工过程。     

个体早期情绪唤起与自我决定及主观活力的关系

以量表测量法初步探索早期情绪唤起与成年后自我决定水平及主观活力之间的关系,试图寻找情绪对人格组织的核心作用的证据。研究发现：①个体在早期父母行为调控中的某些基本情绪的唤起可以有效预测其成年后的自我决定和主观活力水平。②个体早期抵触情绪唤起对其成年后的自我决定和主观活力具有消极作用,而非负性情绪唤起则具有积极作用。研究结果支持基本情绪理论关于情绪处于人格结构的核心地位的观点。
