距离、观察姿势对大小知觉的影响

問題 大小知觉是視知觉心理学中重要問題之一,也是人在实践活动中所經常接触的問題。前人研究表明,大小知觉总是与知觉对象的距离成一定的关系,并提出所謂大小-距离不变假設(Size-Distance Invariace Hypothesis)来說明这种現象。在一般情况下,对象离开观察者愈远,网膜视象随距离按比例縮小,而观察者所知觉的大小却仍接近对象的原来实际大小(物理大小),也就是說大小知觉保持着一定的恆常性。这是大小知觉与距离关     

阅读中疲劳、心理负荷因素对瞳孔大小的调节作用

以大学生为被试,探讨文本阅读过程中,疲劳和心理负荷因素对瞳孔大小的调节作用。实验一主要检验文本阅读中的疲劳效应;实验二分析不同文本加工水平者的瞳孔变化差异,以探讨疲劳和心理加工对瞳孔变化的作用。结果表明：在文本阅读中,疲劳会使瞳孔缩小,心理负荷增大会使瞳孔放大,一定的心理负荷可以起到维持瞳孔大小不变的作用;疲劳和心理负荷因素对瞳孔大小的调节存在颉颃效应。     

THE USE AND ABUSE OF FACTOR ANALYSIS IN COMMUNICATION RESEARCH

This paper discusses several decisions that researchers must make in their application of factor analysis to data related to communication phenomena. Several suggestions are provided to aid researchers in reaching appropriate decisions.     

THE EFFECT OF A MASTERY PRACTICE DESIGN ON LEARNING AND TRANSFER IN BEHAVIOR MODELING TRAINING

This study employed a pretest-posttest control group design in a field setting with 38 supervisors and managers to test the effect of a theory-based mastery practice design for interpersonal skills training. The mastery practice protocol was drawn from recent research in cognitive and educational psychology on complex skill acquisition. Dependent measures included knowledge retention, behavioral skill demonstration, and far transfer to the workplace based on a multirater 360-degree survey instrument. In addition, qualitative data were collected using a semistructured interview process. Comparison of the mastery practice design to conventional behavior modeling workshop practice indicated improvements in retention and behavioral demonstration measures but failed to document any effect on transfer. Implications for future research and practice are discussed.     

THE ACQUISITION OF SIMPLE AND COMPOUND SENTENCE STRUCTURE IN AN AUTISTIC CHILD1

Contingent reinforcement and imitative prompts were used to teach an autistic child to use simple and compound sentences to describe a set of standard pictures. When imitative prompts and reinforcement were discontinued, correct use of simple sentences declined, but increased again when imitative prompts and reinforcement were re-instated. When imitative prompts and reinforcements were used to teach compound sentence structure, correct use of simple sentences declined and correct use of compound structure increased. At the end of training, the child also used novel compound sentences to describe a set of pictures on which he had received no direct training.     

THE MODERATING EFFECT OF SITUATIONAL CONTROL OF PERFORMANCE VARIANCE ON THE RELATIONSHIP BETWEEN INDIVIDUAL DIFFERENCES AND PERFORMANCE1

The present study investigated the existence of a moderating effect for situational control of performance variance on the relationship between individual differences and performance. An experimental simulation was conducted and validity coefficients were calculated. Results supported the presence of the predicted moderating effect. The implications of these data for validation research and testing programs are discussed.     

AN ANALYSIS OF AND INTERVENTION IN THE SEXUAL TRANSMISSION OF DISEASE

Sexually transmitted diseases are a serious threat to the public health. Indeed, when an individual seeks medical treatment for a sexually transmitted disease, health authorities frequently attempt to identify, procure, and treat that individual's sexual contact(s). We conducted a comparative analysis of three alternative approaches to tracing the sexual partners of individuals diagnosed as having a sexually transmitted disease. The first approach involved counseling individuals (n = 27) infected with either gonorrhea or nongonococcal urethritis and exhorting them to procure their sexual partners for treatment. In addition to counseling, the second and third approaches involved distributing “occasion cards” for patients to use when informing sexual contacts of the need for treatment. Moreover, in the second approach, the counselor (a nurse or physician) informed infected patients (n = 19) that they and their partners could waive the $3 clinic fee contingent upon the partners seeking treatment within 1 week. In the third approach, the counselor asked infected persons (n = 19) to accept a follow-up telephone contact if their sexual partners failed to seek treatment within 1 week. The third approach was most effective. Ninety percent of the partners identified through this approach sought treatment, versus only about 60% of the partners in the other two conditions. The third approach was also the least expensive, costing about $2.95 to procure each partner for treatment.     

主体因素对学习判断孤立效应的影响

通过两个实验探讨主体因素差异对学习判断值及其孤立效应的影响。选取708名高一学生作为被试,男女各半。实验一考察主体对材料性质的觉知感差异对学习判断值及其孤立效应的影响,实验二考察主体对材料项目数的确定感差异对学习判断值及其孤立效应的影响。结果表明,提高主体对材料性质的觉知感,可以提高学习判断值,但并没有提高学习判断的孤立效应;而提高主体对材料项目数的确定感,不仅可以提高学习判断值,而且可以提高学习判断的孤立效应。     

少年赛中情绪影响运动成绩的研究

实验以46名少年为对象,以400m跑为内容,在被试者不知道的情况下,把他们分为鼓励(表扬)组和挫折(批评)组。预先测得他们400m跑的平时成绩,做为实验后被试自己与自己成绩比较的出发点。具体实验之前,告诉被试者,这次测验400m跑,既看“达标”如何?也看“技评”如何? 实验是在400m跑途中,于100m,200m,300m处各设数人为“技评”鉴别者。每两个人一起跑,一个人受“表扬”,一个人挨“批评”。 结果,接受积极刺激的少年,多数唤起增力情绪,并做出积极的反应,但也有少数人出现了减力情绪,做出消极的反应。而接受消极刺激者,正与此相反。 表扬比批评具有更大的动力性质,教师在教学中宜多用表扬,对少年的表扬与批评,要注意年龄与性别特点。     

THE EFFECT OF REPERTORY GRID SCALE SIZE AND RATING DIRECTION ON STRUCTURAL MEASURES OF DIFFERENTIATION

Previous work by Soldz and Soldz (1989) indicated that variations in repertory grid features can have a significant impact on the interpretation of the Landfield Functionally Independent Construction Score (FIC), which is a measure of cognitive differentiation. In this study, we showed that four different grid measures (FIC, Total number of zeroes, and the number of midpoint ratings used to indicate either equality or nonapplicability) can be effected by the use of a certain scale size (3-point, 7-point, 13-point), and by the direction of administration (completing the grid in a downwards direction vs. an across-wise direction). In addition, correlations between the number of zero ratings and the total FIC scores for each of the different scale sizes and directions showed evidence to support and to qualify previous work conducted by Soldz and Soldz (1989). In general, high positive correlations were found, suggesting the impact of zero ratings on FIC scores. But the magnitude of the correlations between the zero ratings and the total FIC scores varied as a function of the scale size, the direction of administration, and the meaning of the zero rating (neutrality vs. nonapplicability), raising theoretical, as well as procedural, considerations for future repertory grid research.     

THE APPLICATION OF EXPLORATORY FACTOR ANALYSIS IN APPLIED PSYCHOLOGY: A CRITICAL REVIEW AND ANALYSIS

Although factor analysis has been a major contributing factor in advancing psychological research, a systematic assessment of how it has been applied is lacking. For this review we examined the Journal of Applied Psychology, Organizational Behavior and Human Performance , and Personnel Psychology over a ten-year period (1975–1984) and located 152 studies that employed factor analysis. We then analyzed the choices made by the researchers concerning factor model, retention criteria, rotation, interpretation of factors and other issues relevant to factor analysis. The results indicate that choices made by researchers have generally been poor and that reporting practices have not allowed for informed review, cumulation of results, or replicability. A comparison of results by time interval (1975–1979; 1980–1984) revealed minimal differences in choices made or the quality of reporting practices. Suggestions for improving the use of factor analysis and the reporting of results are presented.     

PROPERTIES OF THE HOLLEY-GUILFORD 'G INDEX OF AGREEMENT' IN R AND Q FACTOR ANALYSIS

The Holley-Guilford G index for 2×2 contingency tables has spatial properties which suggest that, as with other such indices, problems may arise in factor analysis of G matrices. Two response models—Guttman's Simplex and the Coombs-Kao conjunctive case—are used to provide data for exploring the behaviour of G. In particular, the claim that G equates person means and variances in Q analysis is not substantiated.     

文章结构分析训练对阅读理解水平影响的实验研究

本研究探讨文章结构分析训练对阅读理解水平的影响,实验发现：（１）在文章结构分析中渗透精加工组织策略训练有助于提高学生阅读理解能力,差生进步更大;（２）训练总体上能提高学生对文章结构的敏感性和对文章信息的保持与回忆;（３）初一学生阅读水平的差异未反映到其对文章结构的敏感性和文章信息的回忆保持上。     

教育因素对认知功能年老化过程的影响

应用言语－操作和人机对话两种方式共１２项作业,完成年龄和教育因素对认知功能影响的研究,被试共７３４人,４６－７５岁．结果表明：（１）年龄和教育因素对认知成绩的影响因作业而异,分别为年龄影响明显（图象自由回忆和无意义图形再认）、教育因素影响明显（卡片分类、图象分类和矩阵填图）、年龄和教育因素影响均明显（符号数字、词对联想学习、听觉和视觉数字广度）或均不明显（心算）．（２）四项非词语性作业速度明显受年龄和教育因素的双重影响．     

照明水平、亮度对比和视标大小对视觉功能的影响

本研究在不同背景照度条件下对不同大小、不同对比度的兰道尔环的辨认进行了实验。主要结果表明:(1)视觉作业水平的提高依赖于视标大小、对比度和背景照度这三个变量及其相互间的关系;在视觉作业水平一定时,视标大小、对比度和背景照度存在着两两对应的代偿关系;(2)以中国人为被试的RCS结果与国外欧美人为被试的CIE推荐的结果基本一致,但前者在低亮度范围内要明显高于后者。
