A FURTHER STUDY OF DIRECT AND INDIRECT SCALING METHODS

The direct method of ratio estimation and the indirect method of pair comparisons were used to construct scales of the political importance of eleven Swedish monarchs. The scale from pair comparisons on the assumption of Case V was a logarithmic transformation of the ratio estimation scale. This is in line with the results obtained in several previous studies.     

FOUR METHODS OF ANALYZING BETWEEN VARIATION FOR THE K-GROUP MANOVA PROBLEM

Four methods of analyzing between variation in the k-group MANOVA problem are considered. Specifically, they are (1) discriminant analysis, (2) stepdown analysis, (3) contrasts on the classification variable and (4) a two group breakdown. These methods are discussed briefly, with certain basic com- puting equations being given. Then a sample problem is used to illustrate how the methods may be applied and interpreted. The univariate h2 (squared correlation ratio) is related t o a corresponding multivariate measure. Also, a variant of h2 is introduced to indicate the proportion of variance in each of the dependent variables which is accounted for by the classification variable.     

A METHOD FOR SCALING VERBAL DISQUALIFICATION

A disqualification is a message that says something “without really saying it”—one that is evasive, indirect, or effectively ambiguous in some other way. This article describes the rationale for, and development of, an objective method for measuring the degree of disqualification in brief written messages: nonexpert judges independently assess four basic elements of the message (sender, content, receiver, context) for ambiguity, by use of a physical scale of length. The raw scale values are standardized for each judge, and the reliability of these values is quite high. Research uses of the method, as well as its limitations and possible modifications, are discussed.     

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.     

PUBLICATION BIAS: A CASE STUDY OF FOUR TEST VENDORS

This article has 2 goals. First, we discuss publication bias and explain why it presents a potential problem for industrial and organizational psychology. After reviewing the traditional failsafe N, or file drawer analysis, we introduce a more sophisticated method of publication bias analysis (trim and fill), which has been developed in the medical literature but is largely unfamiliar to industrial and organizational psychology researchers. Second, we demonstrate trim and fill by applying it to validity information reported in the technical manuals of 4 test vendors. In doing so, we assess the likelihood that criterion-related validity information provided by test publishers may overestimate test validity. In our analysis of 18 validity distributions, we found evidence of either no or minimal bias for 2 of the vendors' distributions and evidence of moderate-to-severe bias in at least 1 distribution from each of the other 2 vendors. In both cases in which publication bias was found, we noted instances in which the publishers tended to report only statistically significant correlations and that this practice was detected using publication bias methodology.     

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 table covers the range from 12 to 48 objects (points) for one to five recovered dimensions.     

A PROPOSAL FOR A COMMON DATA EXCHANGE FORMAT FOR REPERTORY GRID DATA

Repertory grid interviews provide information about the psychological space of people in matrix-structured form, providing a basis for the statistical analysis of results. Today there are many software packages available for the elicitation and analysis of repertory grids, most of them with unique features. But access to this wealth of options is restricted because, at present, repertory grid programs store data in different formats. As a result, anyone who has tried to exchange data between programs knows that this is not an easy task, as the exchange typically requires tedious and error-prone reentering of the data. To enable direct and error-free data exchange between repertory grid programs, we propose a common data format for repertory grid software based on the Extended Markup Language (XML). It is important to note that users do not have to learn XML to take advantage of this common data format. Data sets of current analysis programs can be translated into XML by utilities. As a basis for further discussion we have developed sample applications and utilities that are based on this new data format.     

违法犯罪者人格多种方法研究

本研究运用问卷法“YG人格测验”、作业法“内田－克雷佩林心理测验”和投射法“色塔人格测验”对126名违法犯罪者进行了测试。结果表明,作业法和投射法人格测验二者相互补充和印证,揭示了违法犯罪者人格的某些特点,问卷法人格测验的结果与前者不一致,应该运用多种方法对违法犯罪者的人格进行研究。     

A SIMPLICIAL DESIGN FOR THE ANALYSIS OF CORRELATIONAL LEARNING DATA

The usual matrix of intercorrelations among trials in a study of the learning process produces a superdiagonal matrix with resulting factors which are uninteresting: viz, a factor for the early trials and a factor for the later trials; with perhaps also a factor for the middle trials. By introducing several independent measures of learning for each trial a more meaningful factor structure can be obtained.

A COMPARISON OF THREE METHODS FOR ELIMINATING DISRUPTIVE LUNCHROOM BEHAVIOR1,2

Three methods of controlling disruptive lunchroom behaviors of elementary school children were compared: basic modification procedures, basic modification procedures plus punishment essays, and basic modification procedures plus mediation essays. During an in-service workshop, six paraprofessional lunch aides received training in these methods to modify three classes of disruptive lunchroom behaviors. They then applied the methods in a counter-balanced design. Fourth- and fifth-grade elementary school pupils were observers and made reliability counts of the target misbehaviors under the various methods. Results indicated that during the periods when aides had been directed to use basic modification procedures plus mediation essays, target misbehaviors were almost totally eliminated and occurred significandy less often than during the periods when they had been directed to use basic modification procedures alone or basic modification procedures plus punishment essays.     

民航飞行学员选拔方法的建立：中德飞行学员能力测验分数的比较

９０年代初,中国民航在有关现代航空人类因素研究的基础上,开始对其飞行员选拔程序展开了一系列的修订工作。随着空中交通密度的逐渐增高,新型喷气客机的问世以及国际航线的不断延伸,从而使今后对高素质飞行员的需要更加迫切。１９９４年中国民航与德国汉莎航空公司携手合作,旨在评价德国这套较为成熟的飞行员选拔程序在中国文化背景下的适应性。该测试系统包括人格、心理运动以及诸如航空知识、操作等能力因素的测量与评价。经一系列汉化及文化适应性修订后,３４６名中国飞行候选者接受本套系统的测试。结果表明,与德国候选者相比,中国被试在技术知识和数学能力上显著优于德国被试,但在心理运动和英语听力方面却显著低于德国样本的均值水平。１９９８年将与中国民航飞行学院一道开展该测试系统的效度研究。     

IMPLICATIONS OF A NEUROPHYSIOLOGICAL APPROACH FOR THE STUDY OF A NONVERBAL COMMUNICATION

This article reviews the neurophysiological literature as it pertains to nonverbal communication. It provides an overview of research on the function of the cerebral hemispheres as related to communication, with particular emphasis on the right hemisphere where most nonverbal communication is processed. Limitations of the neurophysiological approach are discussed. Finally, implications of the neurophysiological approach are discussed for: (1) defining nonverbal communication, (2) the phylogenetic development of communication in humans, and (3) communication research and theory.     

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.     

A CROSS-CULTURAL STUDY OF RECOGNITION MEMORY FOR FACES1

The hypothesis that subjects would show superior memory for faces of members of their own ethnic group compared with those of a different ethnic group was tested in a cross-cultural experiment. Thirty two African and 32 European subjects were presented with coloured photographs of ten black Africans and ten white Europeans, with the instruction to try to remember them. Twenty four hours later, the subjects were presented with the same photographs shuffled with an equal number of new photographs of Africans and Europeans, and were asked to identify those they had seen before. The index d' was used as a measure of recognition. As predicted, European subjects were superior at recognising European faces compared with African faces, and African subjects were superior at recognising African faces compared with European faces. Response bias data indicated that European subjects had a differential response bias for the photographs of the two ethnic groups, but African subjects did not differ in their bias towards the two ethnic groups. African subjects did, however, show differential response bias for sex within the European faces. The results were discussed in terms of perceptual discrimination and stereotyping.
