中国古代心理测验及其特色与价值   总被引:3,自引:0,他引:3  
燕良轼 《心理科学》1999,22(2):132-135
文章对中国古代心理测验历史进行反思,认为中国古代心理测验是以知人观为其理论依据,渊远流长,内容丰富,既有类似于现代西方的小时空心理测验,也有西方至今尚未充分关注的大时空心理测验。文章还阐释了中国古代心理测验的几个具体特色;置测验于生活实际中;文化与超文化测验井存;测验与选拨、训练、教学、娱乐相结合;精于定性,疏于定量。  相似文献

中介效应检验程序及其应用   总被引:273,自引:10,他引:273  
讨论了中介变量以及相关概念、中介效应的估计;比较了检验中介效应的主要方法;提出了一个检验程序,它包含了依次检验和Sobel检验。该程序检验的第一类和第二类错误率之和通常比单一检验方法小,既可以做部分中介检验,也可以做完全中介检验。作为示范例子,引入中介变量研究学生行为对同伴关系的影响。  相似文献

The differential-outcomes effect is manifest as more accurate performance of a delayed conditional discrimination when alternative choice responses are followed by different reinforcers than when they are followed by the same reinforcer. In Experiment 1, a differential-outcomes effect was demonstrated within sessions by signaling the duration of food access for correct responses with stimuli appearing in conjunction with the sample stimuli. The delayed matching-to-sample performance of 5 pigeons was more accurate when green choice responses (matching a green sample) were followed by 3.5-s food access and red choice responses (matching a red sample) were followed by 0.5-s food access (different-outcome trials) than when the correct choice responses were both followed by 1.5-s reinforcers (same-outcome trials). In Experiment 2, the acquisition of this differential-outcomes effect was characterized by a progressive decrease in rate of forgetting on different-outcome trials and no change in rate of forgetting on same-outcome trials. In addition, accuracy at the shortest delay intervals for both different-outcome and same-outcome trials increased over acquisition, but to a greater extent for different-outcome trials. These data suggest that both memorial and attentional (time-dependent and time-independent) factors contribute to the differential-outcomes effect.  相似文献

We provide a unified, theoretical basis on which measures of data reliability may be derived or evaluated, for both quantitative and qualitative data. This approach evaluates reliability as the proportional reduction in loss (PRL) that is attained in a sample by an optimal estimator. The resulting measure is between 0 and 1, linearly related to expected loss, and provides a direct way of contrasting the measured reliability in the sample with the least reliable and most reliable data-generating cases. The PRL measure is a generalization of many of the commonly-used reliability measures.We show how the quantitative measures from generalizability theory can be derived as PRL measures (including Cronbach's alpha and measures proposed by Winer). For categorical data, we develop a new measure for the general case in which each of N judges assigns a subject to one of K categories and show that it is equivalent to a measure proposed by Perreault and Leigh for the case where N is 2.Bruce Cooil is an Associate Professor of Statistics, and Roland T.

一般能力倾向成套测验简介及其中国试用常模的修订   总被引:5,自引:0,他引:5  
本文对一般能力倾向成套测验作了简要的介绍。为了试用,对它进行了修订。版本是以日本劳动省1983年修订版为蓝本的。日本的版本是来自美国。为了适合国情,对该测验在三个方面作了微小的变动。修订工作自1989—1992年初。标准化样组是由全国17个中等以上城市初二至高三学生2148名构成的。男女学生的比例为1:1。该测验在结构效度上有很好的证据,稳定信度分数相当好。  相似文献

This paper reports a study of the relation between demographic variables and neuropsychological test performance in a sample of 141 normal subjects. A preliminary analysis demonstrated the importance of age, educational level, sex, and Verbal IQ for the prediction of neuropsychological test performance. The main study is a detailed analysis of the relation between these four variables and neuropsychological test performance. The results are presented in the form of standardized regression coefficients and are discussed in relation to the problem of predicting expected premorbid performance in neuropsychological tests.  相似文献

This note is concerned with differences and similarities between structural models for analyzing change, which are conceptualized within two different modelling traditions: the one based on the classical test theory, and that within the factor-analytic approach. It is shown that these two possibilities lead to models for studying change, which are indistinguishable when using for data analytic purposes structural modeling programs, such as LISREL, EQS, COSAN, LISCOMP, RAMONA, EzPATH, SAS PROC CALIS. The reason for this data-analytic equivalence of the two conceptually different types of models is the confounding of their differences in the corresponding implied covariance matrix structures.  相似文献

A model-based modification (SIBTEST) of the standardization index based upon a multidimensional IRT bias modeling approach is presented that detects and estimates DIF or item bias simultaneously for several items. A distinction between DIF and bias is proposed. SIBTEST detects bias/DIF without the usual Type 1 error inflation due to group target ability differences. In simulations, SIBTEST performs comparably to Mantel-Haenszel for the one item case. SIBTEST investigates bias/DIF for several items at the test score level (multiple item DIF called differential test functioning: DTF), thereby allowing the study of test bias/DIF, in particular bias/DIF amplification or cancellation and the cognitive bases for bias/DIF.This research was partially supported by Office of Naval Research Cognitive and Neural Sciences Grant N0014-90-J-1940, 4421-548 and National Science Foundation Mathematics Grant NSF-DMS-91-01436. The research reported here is collaborative in every respect and the order of authorship is alphabetical. The assistance of Hsin-hung Li and Louis Roussos in conducting the simulation studies was of great help. Discussions with Terry Ackerman, Paul Holland, and Louis Roussos were very helpful.  相似文献

运动竞赛焦虑量表中国常模的修订   总被引:7,自引:0,他引:7  
祝蓓里 《心理科学》1993,16(2):99-103,94
运动竞赛焦虑量表是由美国的马腾斯专为运动员编制的特质焦虑量表。它是一种与特定的情境相结合的、能够有效地测出被测者通常在运动竞赛(或游戏)时焦虑水平的量表。我们在全国六大区十四个省市抽取了2,988名被试,修订了10—12岁(男、女),13—15岁(男、女),16—18岁(男、女)和19—25岁(男、女)的八个常模。同时,进行了效度和信度检验。本量表可以作为对业余的或专业的运动员进行运动竞赛焦虑的诊断与研究用。  相似文献

Operant hoarding: a new paradigm for the study of self-control.   总被引:2,自引:2,他引:0       下载免费PDF全文
In the first of four experiments, rats were exposed to a modified multiple continuous reinforcement-extinction schedule during 15-min daily sessions. In one condition (saves condition) with the cuelight on, a single lever press produced a food pellet, briefly extinguished the cuelight, and started a clock. Saves (additional lever presses with interresponse times less than 1 s) produced an additional food pellet, briefly extinguished the cuelight, and restarted the interresponse time clock. The cuelight was extinguished 1 s after the last lever press and remained off during a 10-s period of extinction, during which no food pellets were delivered. In the other condition (savings account condition), the contingencies were the same except that the cuelight was extinguished and was not reilluminated after the initial lever press, and the delivery of all food pellets in the reinforcement component was delayed until the onset of extinction. In both conditions, rats made saves, but mean saves (total saves divided by the number of reinforcement components) were slightly reduced in the savings account condition. In Experiment 2, using six equally spaced 15-min sessions per day on alternate days, saves were either followed immediately with food and brief cuelight offset (saves condition) or were not reinforced at all. Mean saves were much greater when saves were reinforced. In Experiment 3, during 5-min daily sessions, saves earned a single pellet (savings account condition) or a number of pellets equal to the ordinal number of the lever press (interest condition). Rats made fewer mean saves, with little change in the food rate, when saves earned interest. In Experiment 4, the rats earned all their food in the operant situation during 24 daily 5-min sessions, these separated by 55-min intersession intervals during which no food was available; otherwise, the conditions were the same as in Experiment 3. In Experiment 4, the shift to interest for saves led to an increase in mean daily mean saves (total daily mean saves divided by the number of daily sessions) as well as to an increase in the number of food pellets delivered in each session. The results are discussed in terms of self-control and behavioral economics.  相似文献
