MULTIDIMENSIONAL RATIO SCALING AND MULTIDIMENSIONAL SIMILARITY OF SIMPLE GEOMETRIC FIGURES

The special case of purely qualitative multidimensional similarity was studied in four experiments concerned with simple geometric figures. A previously proposed equation did not describe the relation between subjective similarity and angular separation of the percept vectors. Factor analyses indicate that in the 'homogeneous' experiments (with parallelogram figures) there were two pairs of inversely related subjective attributes which vary as a function of the difference between the horizontal and vertical axes of the parallelogram, and that in the 'heterogeneous' experiments (different figures) there were four main independent subjective attributes.     

THE USE AND UTILITY OF THE MONOTONE CRITERION IN MULTIDIMENSIONAL SCALING

The monotone criterion as a multidimensional scaling technique is theoret- ically and empirically evaluated using the algorithms of Kruskal (MDSCAL) and Guttman-Lingoes (SSA-1). Geometric configurations are used to test the recovery capabaty and other aspects of MDSCAL and SSA-1. In addition to theoretical shortcomings, the monotone criterion permits results which do not correspond to the shape of the input data. Because of its deficiencies, alterna- tive goodness-of-fit criteria are suggested in preference to the monotone criterion.

MULTIDIMENSIONAL SCALING OF LARGE CHROMATIC DIFFERENCES BY NORMAL AND COLOR-DEFICIENT SUBJECTS

The following two articles offer a glimpse at current experimental psychology in the Soviet Union, normally screened from the English-speaking world by all but impenetrable language barriers. The accompanying Commentary by Tarow Indow helps place these contributions in the framework of contemporary work on the psychophysics of color perception.   Abstract —
Fifteen normal trichromatic subjects, two protanopes, and two deuteranopes judged pairs of successively presented foveal color stimuli. Multidimensional scaling of the data yielded estimates of a three-dimensional space with axes interpreted as red–green, blue-yellow, and white-black. For color-deficient subjects, the average radius of the space differed from that of normals, being smaller for the protanopes and larger for the deuteranopes. For both types of color deficiency, the blue-yellow axis was stretched relative to the red-green, more strongly in the protanopes. The findings are taken to support the generality of a "spherical" model.     

DIMENSIONS OF WORK OUTCOMES: A MULTIDIMENSIONAL SCALING APPROACH

There exists a need for basic research on the nature of work outcomes, to facilitate integration of theory and results and to aid in the sampling of outcomes for research and evaluation. Existing research, primarily using factor analysis, has led to a hierarchical model, with numerous sub-factors grouped under the major factors of "intrinsic" and "extrinsic." Recent research, however, has shown that industrial/organizational psychologists do not agree on the definition of intrinsic and extrinsic. It is argued that a more useful approach is a dimensional model, which allows each work outcome to be described by a set of values on multiple dimensions. A multidimensional scaling analysis of 21 outcomes yields a latent structure with three dimensions: value attached to the outcome by society, level of psychological need met, and extent to which the outcome is inherent in the work itself. Implications for the sampling of outcomes and integration of different literature are discussed. The results suggest that a multidimensional model of work outcomes is more useful than a categorical approach built on the intrinsic/extrinsic dichotomy.     

华人人际关系的概念化——针对中国香港大学生的实证研究

以杨中芳所构建的华人人际关系概念化理论模型为蓝本,并用以往的实证研究方法为基础,揭示了当代华人对人际关系如何进行概念化及其潜在的认知维度。杨氏模型认为华人人际关系主要由既定成分、情感成分和工具成分组成。该研究以中国香港大学生为被试进行调查,首先采用访谈的形式,分家族、学校及日常生活情境建立人际关系清单。然后采用多维量法（Multi-dimensional scaling）处理被试对关系进行分类的数据。结果发现,在不同的生活情境中,被试均依据情感程度对关系进行分类。在等级差异明显的家族和学校情境中,被试依据辈份和等级差异的突显性进行区分;而在等级差异小的生活情境中,则采用功利程度为标准。本文对被试在不同情境中所采用的不同维度进行了讨论,并提出华人人际关系的义务具有工具性质的实证结果

DYNAMICS OF CULTURAL IN-BETWEENITY: AN EMPIRICAL STUDY*

The Dialectical Theory of Cultural In-Betweenity proposes three main identification patterns among the black intelligentsia: Capitulation to the dominant culture, Revitalization of the indigenous culture, and Radicalization of both so as to arrive at a new and higher synthesis. Three scales corresponding to the identification patterns were constructed and a comparative study was conducted on two college samples. One group consisted of 45 Somali students being trained in the United States. The other group consisted of 57 Somali students being trained in Somalia. Specific hypotheses comparing the two groups were tested and mostly confirmed by means of various psychological instruments. Investigation into the component features of each identification pattern led to further refinement of the theory. Factor analytic explorations suggested the prevalence of distinct ethos, group reference, and self-image within each orientation. Capitalist ethos, elitism, and inferiority complex seem to be characteristic of Capitulation. Traditional ethos, race consciousness, and identity-rumination were delineated for Revitalization. Socialist ethos, class consciousness, and co-optation fears emerged as distinct components of Radicalization. The Dialectical Theory of Cultural In-Betweenity and the empirical findings are then discussed within the broad historical framework of colonialism and racism.     

COCAINE ADDICTS AND THEIR FAMILIES: AN EMPIRICAL STUDY OF THE PROCESSES OF IDENTIFICATION

The processes of identification between adolescent cocaine addicts and their parents were studied in 402 subjects, in total 134 familial triads (father"mother"son), subdivided into two groups of 67 triads, one of these groups having as the child an adolescent of masculine sex dependent on cocaine and the other, equal in number, being a control group, duly matched for age and socio-economic status. The instrument employed was the Rorschach test (1922), limited to the application of the Lerner Defense Scale (LDS; Lerner & Lerner, 1980). The findings in the affected triads showed up as consistent statistically for the presence of intense processes of pathological identification, especially between father and son, a sign of the importance of the presence of disturbances of paternal function in the development of this addiction. The utilisation of very regressive defence mechanisms, above all of projective identification, was the predominant mode of procedure in triads with a dependent child. In comparisons between the fathers the odds ratio (OR) for projective identification was 8.66 to 1, which points to the association between cocaine addiction and the primitive mental functioning of the fathers. With empirical methodology these findings serve to corroborate the psychoanalytical conclusions based on studies of single case studies, testifying that the dysfunctions of identificatory phenomena in familial functioning are predominant in the mental organisation of cocaine addicts.     

A TABLE OF EXPECTED STRESS VALUES FOR RANDOM RANKINGS IN NONMETRIC MULTIDIMENSIONAL SCALING

The results of applying a nonmetric multidimensional scaling algorithm to sets of pseudo random data are used as the basis for constructing, by means of regression techniques, a table which will assist a user to decide whether empirically obtained data sets are the result of a random process.

THE EFFECTS OF VARIABILITY AND RISK IN SELECTION UTILITY ANALYSIS: AN EMPIRICAL COMPARISON

To date, utility analysis research has derived point estimates of the expected utility value for human resource management programs or interventions. Utility estimates are usually quite large, but they fail to reflect the size and shape of the utility distribution. The present study investigated utility estimate variability for the selection utility of using the Programmer Aptitude Test to select computer programmers in a medium-sized computer manufacturing organization. Utility calculations incorporated financial/economic factors as well as employee flows over time. The distributions for each utility parameter were empirically estimated, and these distribution estimates were combined through a Monte Carlo analysis to yield a distribution of total utility values. Monte Carlo results were compared to three other risk assessment approaches: (1) sensitivity analysis, (2) break-even analysis, and (3) algebraic derivation of the distribution. Results suggest that the distribution information provided by the Monte Carlo analysis more completely described the variability and riskiness associated with the expected utility value. Future research suggested by these findings is discussed.     

COGNITIVE RESTRUCTURING AND MENTAL CONTAMINATION: AN EMPIRICAL RE-CONCEPTUALIZATION

The main goal of this article is to propose a cognitive technology for blocking the impact of mental contamination during cognitive restructuring in cognitive-behavioral and rational-emotive therapy, by using fundamental research findings from cognitive psychology. In step 1, after a review of the relevant cognitive and social psychology literature, the authors elaborated several techniques hypothesized to control mental contamination. In step 2—Experiment I—the authors tested the efficacy of these techniques in blocking mental contamination. The three techniques that proved to be effective in controlling mental contamination were: (a) the global restructuring technique; (b) the rational anticipation technique; (c) the incompatible information technique. In step 3—Experiment II—these techniques were adapted and tested in clinical setting using a single case experiment design-multiple baselines across subjects (five subjects with simple phobia). The techniques were shown to be effective in both stimulating the assimilation of new adaptive cognitions (i.e., global restructuring and incompatible information technique) and in preventing relapse (i.e., rational anticipation technique). Future directions for research are discussed.

A MULTIDIMENSIONAL STUDY OF PERCEPTUAL-EMOTIONAL QUALITIES IN MUSIC

W edin L. A multidimensional study of perceptual-emotional qualities in music. Scand. J. Psychol ., 1972, 13 , 241–257.—Forty musical excerpts were judged in terms of emotionally coloured adjectives using a check-list procedure and different types of sorting procedures. Similarities were estimated by rank correlation or simple confusion indices and nonmetric multidimensional scaling was applied. Three dimensions were txtracted and labelled Intensity-Softness, Pleasantness-Unpleasantness and Solemnity-Triviality. These qualities were then related to the stimulus qualities judged in more "technical" terms like tempo, pitch, modality etc.
