正视及斜视条件下的深度觉及距离判断

本实验探讨了影响深度觉及距离判断的有关因素。实验分三部分:一、双眼正视(0°)和双眼斜视(45°)条件的深度觉辨别实验;二、双眼正视(0°)条件下不同距离相对判断实验;三、双眼斜视(45°)条件下的相对距离判断实验。实验结果表明:在双眼正视条件下(0°),深度觉辨别最准确,双眼斜视(45°)条件下,误差值明显增加,而单眼正视条件下,误差值最大。双眼斜视(45°)条件下的相对距离判断的误差值明显较之双眼正视(0°)条件下的为大。对2/4的相对距离判断的准确性均较之对1/4和3/4的距离为高。在双眼斜视条件下,眼肌调节发生变化,睫状肌紧张度增加,视觉易于疲劳可能是造成深度觉及距离判断准确性降低的主要原因。     

FACTORS INFLUENCING TWO-DIMENSIONAL FORM PERCEPTION

The perceived shape of a circle and ellipse has been studied as influenced by the size of the figure, size of the reference frame, contrast and intensity. It was found that these factors have a systematic influence upon form perception. The data are considered within the context of the shape slant invariance hypothesis and are interpreted as providing evidence against this hypothesis as applied to the proximal form.     

语意好恶度在人物观感研究中构成的系统性偏差

本研究要旨在探讨问卷中题目的语意好恶度在人物观感研究中所构成的系统性偏差效应。被试为87名大学生。他们需要评定如果要在某一项专业上有优良的表现,哪些性格特征会比较重要。我们把被试随机地分成三组,然后指示每一组被试分别就三种性质很不同的专业的其中一种评鉴121项性格特征的重要性。跟着我们采用每一性格特征的重要度评分与它的语意好恶值进行了一连串的相关分析。结果发现性格特征形容词的语意好恶度可能会对被试在人物观感研究中的评分构成系统性偏差的。最后笔者针对这研究结果引申出来的方法问题提出了一些建议。     

EXPOSURE TO INDUSTRIAL AND URBAN ENVIRONMENTS AND FORMAL SCHOOLING AS FACTORS IN PSYCHOLOGICAL DIFFERENTIATION

The influence on psychological differentiation exerted by exposure to industrial and urban environments and to formal schooling was investigated with the help of Story-Pictorial EFT administered on 240 7–10-year-old children belonging to the Santhal tribe residing in and around an industrial city in Bihar. A 2 × 2 × 2 ANOVA performed on differentiation scores revealed significant main effects of industrial and urban exposures, and of schooling. Significant 3-way interaction effect indicated that the impact of urbanization in the industrial and non-industrial settings varied with exposure to formal schooling, and that the main effects in spite of their being statistically significant have to be taken with caution. Impact of the three factors on psychological differentiation is interpreted in terms of changes induced through acculturation that alter the experiential base of the individual as well as cultural characteristics of this environment.     

ECOLOGY AND SOCIALIZATION AS FACTORS IN FIGURAL ASSIMILATION AND THE RESOLUTION OF BINOCULAR RIVALRY1

L'étude des facteurs culturels en matière de perception et L'étude des facteurs culturels en matière de personnalité ont été, jusqu' à présent, relativement séparées. L'A. propose un modèle qui permet d'intégrer les deux domaines en faisant L'hypothèse d'une relation indirecte entre L'ecologie et les réponses perceptives et d'une relation directe qui correspondrait à celle mise en évidence par les études de laboratoires classiques entre fréquence de L'expérience passée et réponse perceptive. Pour valider le modèle, L'A. utilise les données de deux expériences qui ont été réalisées avec des sujets Temne et Esquimaux et qui portent L'une sur la reproduction de figures ambiguës présentées au tachistoscope et L'autre sur la résolution de rivalités binoculaires.     

SPEECH PERCEPTION AS A TALKER-CONTINGENT PROCESS

Abstract— To determine how familiarity with a talker's voice affects perception of spoken words, we trained two groups of subjects to recognize a set of voices over a 9-day period One group then identified novel words produced by the same set of talkers at four signal-to-noise ratios Control subjects identified the same words produced by a different set of talkers The results showed that the ability to identify a talker's voice improved intelligibility of novel words produced by that talker The results suggest that speech perception may involve talker-contingent processes whereby perceptual learning of aspects of the vocal source facilitates the subsequent phonetic analysis of the acoustic signal     

STUDIES OF PERCEPTION AND REASONING IN ZAMBIAN CHILDREN

Perception et raisonnement chez les enfants zambiens. — l'A. présente une série de recherches expérimentales qui ont été réalisées ou récemment entreprises par l'Unité de Recherche sur le Développement humain de l'Université de Zambie, dans les domaines de la perception et du raisonnement. II attire l'attention sur ce qu'impliquent, pour tout travail expérimental dans ces deux domaines, les limites qui interviennent du fait de la culture et de la langue, dans la communication qui est faite au sujet du stimulus ou de la tâche requise, et ceci particulièrement quand il s'agit d'enfants qui ont ou vont avoir l'âge de commencer l'école. Dans la mesure où ces difficultés peuvent être réellement surmontées, ce qui a été réalisé jusqu'à maintenant montre quel défi et quelle occasion représente pour la psychologie expérimentale le travail dans des pays en voie de développement. II s'avère également qu'il faut s'attendre à un important décalage temporel avant qu'un changement à large échelle ne puisse prendre place dans les stimuli et les motivations du milieu traditionnel.     

PICTORIAL DEPTH PERCEPTION IN SCOTTISH AND GHANAIAN CHILDREN

Published research employing the Hudson Test is critically examined, leading to the conclusion that differences in methods and procedures make direct comparisons of the outcome of different studies inappropriate. Some limitations of the test itself are pointed out, in particular the ignoring of chance expectations, failure to exclude the operation of response sets, and ambiguities about the scoring. Tentative generalizations emerging from previous research are summarized, and the object of the study is to verify them. A newly developed test of three-dimensional perception is described, which also consists of pictures but requires less reliance upon verbal instructions. Samples of 60 Scottish and 60 Ghanaian primary school children in classes 2, 4 and 6 were tested with both the Hudson and the new test. While results still indicated a significant cultural difference in the performance on both tests, Ghanaian children experienced much less difficulty with the new test and the gap between them and Scottish children was relatively small as compared with the Hudson Test result. It is concluded that measured ability to perceive pictorial depth is in considerable part a function of the specific method used for assessment, and that African shortcomings with regard to this ability have probably been exaggerated in the past.     

STUDIES IN VISUAL PERCEPTION OF ARCHITECTURAL SPACES AND ROOMS

G arling T. Studies in visual perception of architectural spaces and rooms. V. Aesthetic preferences. Scand. J. Psychol ., 1972. 13 , 222–227.—Depicted urban spaces were rated by 24 subjects with respect to pleasantness. The results for colour photographs, 'detailed' and 'undetailed' perspective drawings were compared. As a common basis for aesthetic preferences, the factors 'variation', 'umbrageousness' and 'openness' were suggested. These factors accounted for 69 % of the variance in multiple linear regression.     

STUDIES IN VISUAL PERCEPTION OF ARCHITECTURAL SPACES AND ROOMS

To test the hypothesis that perceived size of space depends on perceived depth, a relation between judged depth and size of space was derived. External spaces were judged from colour photographs by the magnitude estimation method. It was found that judged depth is a power function of physical depth and judged size of space a power function of physical size (rectangular area) or of judged depth times perceived width. The results indicate deviations from the derived relation and some explanations for these are discussed. Further research is needed to verify the proposed hypothesis.     

A PRACTITIONER-BASED ANALYSIS OF INTERVIEWER JOB EXPERTISE AND SCALE FORMAT AS CONTEXTUAL FACTORS IN SITUATIONAL INTERVIEWS

Since the first published Situational Interview (SI) study (Latham, Saari, Pursell, & Campion, 1980), research has shown practical and psychometric support for the usefulness of this behavioral interview method. However, such studies have often failed to distinguish the effects of "interview context" factors, such as the SI's behaviorally anchored scale and the use of job expert interviewers on SI ratings. To aid HR managers interested in adopting a behavioral interview system, this study examined the contributions of the SI's behaviorally anchored scale and the interviewer's job expertise to the interrater agreement and accuracy of ratings of situational questions. Two police samples (job content experts) and a student sample (naive raters) showed that ratings of videotaped interviews for police sergeant/lieutenant positions based on the SI scale were significantly superior to those gained using a more traditional rating format, and that job experts did not produce better ratings than naive raters.     

VALUE AND SIZE PERCEPTION

A detailed review is presented of studies related to the accentuation hypothesis of Bruner & Goodman (1947). It is found that the results from (1) coin studies, (2) symbol studies, and (3) other studies are conflicting and do not substantiate the hypothesis. Through an analysis of this hypothesis and a specification of the concept of perception, the various designs are found to be inadequate for demonstrating perceptual accentuation of size. The hypothesis is forwarded that value asserts an influence upon imaginary processes related to the experience of size.     

人眼深度运动知觉的研究

人类的深度运动知觉,是通过检测二维平面内的相对运动而形成的。本文在心理物理学实验基础上,揭示该机制的数学与生理学实现形式。视觉系统中存在对视平面内的相对运动敏感的神经元,构成深度运动的检测机制,产生单眼深度运动知觉与双眼深度运动知觉。在心理学上,视觉利用物体视角变化及大小知觉的恒常性判断深度运动。文中还初步讨论了人类的深度运动知觉与蜜蜂,家蝇等昆虫的深度运动知觉的区别。
