THE LAW OF CATEGORICAL JUDGMENT AND THE MEASUREMENT OF COLOR CONSTANCY

The scaling method used by von Fieandt, Ahonen & Järvinen (1964) for measuring color constancy is discussed. It is argued that (i) the underlying scaling model and the experimental procedure they employed are incompatible, and that (ii) the analytical procedure they applied to the data for obtaining the empirical scale values is incorrect. The data are reanalyzed, and the goodness of fit of both the original and the present results is evaluated.     

A SCALING METHOD FOR MEASURING COLOR CONSTANCY

Recently developed types of indirect psychophysical scaling method served as starting point in finding a handy procedure for measuring differences in the degrees of 'color constancy'. A design for carrying out categorical comparisons with color paper proofs was constructed. The raw scores, given as percentage distributions, prove transformable into standard scale values. These demonstrate the shifted positions of the colors in question when presented in alternating conditions of illumination.     

FUTILITY AND THE VARIETIES OF MEDICAL JUDGMENT

Pellegrino has argued that end-of-life decisions should be based upon the physician's assessment of the effectiveness of the treatment and the patient's assessment of its benefits and burdens. This would seem to imply that conditions for medical futility could be met either if there were a judgment of ineffectiveness, or if the patient were in a state in which he or she were incapable of a subjective judgment of the benefits and burdens of the treatment. I argue that a theory of futility according to Pellegrino would deny that latter but would permit some cases of the former. I call this the “circumspect” view. I show that Pellegrino would adopt the circumspect view because he would see the medical futility debate in the context of a system of medical ethics based firmly upon a philosophy of medicine. The circumspect view is challenged by those who would deny that one can distinguish objective from subjective medical judgments. I defend the circumspect view on the basis of a previously neglected aspect of the philosophy of medicine -- an examination of varieties of medical judgment. I then offer some practical applications of this theory in clinical practice.     

4～6岁幼儿相似性判断与类别判断的知识效应

采用类别知识的分类学习模式,选取72名4-6岁幼儿作为被试,对相似性判断和类别判断的知识效应进行实验研究。结果表明：（1）相似性判断和类别判断存在知识效应。（2）相似性判断的知识效应存在显著的年龄差异,类别判断的知识效应不存在显著的年龄差异;5岁是知识学习对幼儿相似性判断产生影响的关键时期。（3）相似性判断知识效应的性别差异不显著,类别判断知识效应的性别差异极其显著,男孩更倾向于依据学习概念所强调的属性进行类别判断。     

PERCEPTION AND JUDGMENT OF FACIAL EXPRESSIONS AMONG THE CHINESE

Perceived relationships among nine facial expressions were structurally represented in a two-space configuration by multidimensional scaling procedure. The two dimensions operative for Chinese judges were interpreted as positive versus negative emotions and open versus controlled styles of expressions. While there was some consensus in identifying seven of the nine intended emotions, interest-excitement and disgust-revulsion were often not recognized. Implications of cross-cultural comparisons in identification rates were discussed.     

SOCIAL PRESSURE IN THE MODIFICATION AND DISTORTION OF JUDGMENT

Pression sociale, modification et distorsion du jugement: une étude interculturelle. — Les résultats d'une réplique interculturelle de L'étude qu'a faite Asch de L'influence d'une pression sociale sur la modification et la distorsion du jugement, montrent que des sujets américains, brésiliens, arabes et chinois manifestent un degré de conformisme presque égal. Mais, pour des sujets rhodésiens, le degré de conformisme est significativement plus élevé que pour tous les autres groupes observés. Des recherches ultérieures sont nécessaires pour déterminer les raisons de L'indépendance ou du conformisme dans les cultures étudiées et pour déterminer également dans quelle mesure il est possible de généraliser les résultats observés dans une situation de type Asch à d'autres situations sociales.     

平滑运动条件下的图形颜色及形状加工特性的研究

本研究对在运动图形识别过程中,有关图形的不同特征（颜色、形状等）的加工特性、方向性效应以及不同空间位置（或时间间隔）对图形识别的影响了探讨。结果发现,视觉系统在运动信息加工时,对目标的不同特征的加工存在不均衡性,加工的难度有差异。颜色的加工难度要比形状的加工难度小。视觉系统对不同运动方向上的图形匹配反应特性也存在差异,图形匹配过程受时间或距离因素的影响,匹配的反应时随着两个比较图形之间的空间距离的增加而减少。     

成年人分类概括力水平的年龄差异及其与记忆的关系

采用威斯康星卡片分类测验（Ｗｉｓｃｏｎｓｉｎｃａｒｄｓｏｒｔｉｎｇｔｅｓｔ,ＷＣＳＴ）对青年组（２０—２５岁）、老年组（６０—６５岁）和老老年组（７０—７５岁）共９０例被试进行分类概括力水平测试,并在结束测试时询问被试与测试有关的几个问题。结果显示：青年组分类概括力水平明显高于老年组;坚持性错误数、非坚持性错误数和总错误数以及坚持性反应数,青年组明显少于老年组;完成作业平均用时间,青年组明显比老年组短;老老年组ＷＣＳＴ多数项目的成绩明显高于老年组;分类概括力水平与记忆密切相关;某些元认知项目与分类概括力水平表现出一致的趋势。     

THE CONSTANCY OF STRUCTURE OF PERCEIVED PARENTAL REARING STYLE IN GREEK AND SPANISH SUBJECTS AS COMPARED WITH THE DUTCH

To be able to contribute to the cross-cultural study of child-rearing practices and psychopathology, this study sought to examine the cross-national generalizability of parental rearing constructs by analyzing self-report data on the EMBU, an instrument designed to assess memories of one's parents' rearing behavior. Of the four primary factors identified originally with Dutch individuals, namely Rejection, Emotional Warmth, Overprotection and Favoring Subject, the first three were replicated in a similar form in a Greek and a Spanish sample of normal research volunteers. Other properties of the factors, their corresponding scales, and the items constituting the scales were such that it would be warranted to carry out mean scale level or pattern comparisons between subjects from the respective countries on the three constructs evidencing cross-national constancy. Scale-level factor analysis of these constructs produced identical two- factor compositions (CARE and PROTECTION) across the Greek, the Spanish and the Dutch samples which further supported this conclusion.     

SUBJECTIVITY, JUDGMENT, AND THE BASING RELATIONSHIP

Moral and legal judgments sometimes depend on personal traits in this sense: the subject offers good reasons for her judgment, but if she had a different social or ideological background, her judgment would be different. If you would judge the constitutionality of restrictions on abortion differently if you were not a secular liberal, is your judgment really based on the arguments you find convincing, or do you find them so only because you are a secular liberal? I argue that a judgment can be based on the considerations the subject claims as justification even when it depends on personal traits.
