ON PSYCHOPHYSICS IN GENERAL AND THE GENERAL PSYCHOPHYSICAL DIFFERENTIAL EQUATION IN PARTICULAR

The first part of the paper discusses theoretical issues regarding the problem of measurement in psychophysics and the suitable choice of a subjective scale, with special reference to the views of Ekman, Ross, Suppes & Zinnes, and Treisman. The theory of the GPDE is discussed more fully than before. In the second part, further empirical confirmation of the GPDE is given for the following combinations of Weber functions: constant-constant, linear-linear, linear-parabolic, parabolic-parabolic.     

ON EISLER'S GENERAL PSYCHOPHYSICAL DIFFERENTIAL EQUATION AND HIS FECHNERIAN INTEGRATION

The general psychophysical differential equation (GPDE) for calculating 'intrasubjective' relations, is reviewed and it is argued that: ( a ) the use of calculus and Weber functions are unnecessary for the determination of such relations: simple algebraic methods are available, ( b ) Taylor's expansion in the derivation of GPDE is not necessary: a short cut method is suggested and applied instead, ( c ) GPDE is untenable as an empirical model, for it is based on one definition and one assumption which are both arbitrary and purely mathematical, ( d ) The sources of error in the validation procedures used by Eisler are pointed out; ( e ) by means of a validity test and the due treatment of a dozen sets of experimental data, the Fechnerian integration as well as GPDE are invalidated.     

EMPIRICAL TEST OF A MODEL RELATING MAGNITUDE AND CATEGORY SCALES

E isler , H. Empirical test of a model relating magnitude and category scales. Scand. J. Psychol ., 1962, 3 , 88–96.—The function K =α log( φ+ q/k) +β seems to describe the relation between category scale values K and subjective magnitudes φ. The additive constant q/k is obtained from the S ds of the magnitude estimates.
The model was empirically confirmed for the loudness and softness of white noise scaled by the methods of magnitude estimation and category rating.     

CONCEPTUAL INTEGRATION AND EMPIRICAL TEST OF JOB DESIGN AND COMPENSATION RELATIONSHIPS

A conceptual integration of job design and compensation draws on interdisciplinary job design, job evaluation, and labor economic theory. It is argued that job design influences the number and level of skills required and the degree to which jobs are physically aversive or hazardous. External labor markets also respond to skill and physical requirements. Job evaluation links job design and market forces by analyzing jobs'compensable factors that reflect these requirements, and then relating them to the market through wage surveys across firms. An empirical examination presents relationships between job design and pay or job evaluation measures. Strongly supportive results replicate in two separate samples (total n = 213 jobs) which differ in industries, job types, skill levels, job design measures, job evaluation measures, and labor markets. Motivational job design had higher job evaluation measures reflecting higher skill requirements, and mechanistic and perceptual/motor design had lower evaluation measures reflecting lower skill requirements. Biological design had lower evaluation measures reflecting physical requirements.     

A WITHIN SETTING EMPIRICAL TEST OF THE SITUATIONAL SPECIFICITY HYPOTHESIS IN PERSONNEL SELECTION

The situational specificity hypothesis of selection procedure validity makes two predictions. The first is that variation in observed validities across settings is caused by real differences in what constitutes job performance. Validity generalization studies to date have provided disconfirming evidence for this prediction by showing that the observed variation is due to statistical and measurement artifacts. The second prediction is that if the situation (i.e., the organization, the setting, the job, the test and the criterion) is held constant, then validity findings will not vary from study to study. This article tests this prediction empirically using data from a unique series of studies reported by Bender and Loveless (1958). The results are contrary to the situational specificity hypothesis and consistent with the hypothesis that variation in observed validities is due to statistical and measurement artifacts that are unrelated to situations and settings. It is concluded that both major predictions of the situational specificity hypothesis have now been empirically disconfirmed.     

AN EMPIRICAL TEST OF A TRAIT-ORIENTED JOB ANALYSIS TECHNIQUE

A trait-oriented job analysis technique based on a checklist of 33 a priori carefully defined traits that encompass elements of the physical, mental, learned, motivational and social domains of the work world is described. The analysis identifies the relevant traits, their levels and weights, in relation to overall job performance. Results of discriminability tests were supportive of the job analysis technique and indicated that incumbents of jobs requiring a particular trait scored higher on measures (predictors) of that trait than incumbents of jobs not requiring that trait. Implications of the results for personnel selection and placement are discussed.     

AN EMPIRICAL TEST OF A ROLE ENACTMENT MODEL OF PERSUASION

Prior research into self-persuasive effects has produced empirical propositions that address the communication process only in a very general way. While psychological formulations are helpful in generating constructs and propositions dealing with intrasource effects as a function of counterattitudinal advocacy, the generalizability of these findings appears limited. Berger's role enactment model of persuasion provides constructs and propositions that comport more exactly with practical communicative experiences. The present study tested the relationships obtaining among concepts crucial to the model. Results confirmed the prediction that role aptitude and task-relevant information were positively related to attitude change. The relationship among the role aptitude, information, and post-performance evaluation variables was not confirmed. The results and refinements of the model were discussed in terms of the potential the model has for more precise tests of communication effects. Message complexity, varying information levels, and other variables were discussed as amenable to tests employing the role enactment model. While self-persuasion situations offer an appropriate paradigm in which to test general social psychology theories, there is some doubt as to the contribution such research can make to our understanding of communication. It is a question of “social significance.” Do sources frequently speak against their “true” attitudes? If so, do intra-source effects tell us much about communication between people? In short, can practical gains be achieved in counterattitudinal advocacy research? We believe that many of the processes associated with self-persuasion are similar to those which characterize interpersonal communication. These similarities are most obvious when one approaches communication research in the context of role theory. (1972, 260)     

AN EMPIRICAL TEST OF A MODEL OF RESISTANCE TO PERSUASION

This investigation synthesized research from several related areas to produce a model of resistance to persuasion based upon variables not considered by earlier congruity and inoculation models. Support was found for the prediction that the kind of critical response set induced and the target of the criticism are mediators of resistance to persuasion. The more critical acts are focused on arguments presented in a persuasive message, the more likely that the critical act will not be distracting and therefore promote counterarguing which will lead people to be resistant to subsequent persuasive messages arguing on the same side of given attitudinal issue. When criticism is less central to message variables and focuses on speaker and/or delivery characteristics, distraction occurs which decreases the probability of counterarguing and induces people to be vulnerable to forthcoming persuasive messages. This is especially true when negative criticism of speaker characteristics reduces threat to present attitudes and reduces motivation to counterargue to protect privately held beliefs. A completely counterbalanced design employing several manipulation checks was created to rule out competing explanations for differential resistance to persuasion.

RETEST EFFECTS IN OPERATIONAL SELECTION SETTINGS: DEVELOPMENT AND TEST OF A FRAMEWORK

This study proposes a framework for examining the effects of retaking tests in operational selection settings. A central feature of this framework is the distinction between within-person and between-person retest effects. This framework is used to develop hypotheses about retest effects for exemplars of 3 types of tests (knowledge tests, cognitive ability tests, and situational judgment tests) and to test these hypotheses in a high stakes selection setting (admission to medical studies in Belgium). Analyses of within-person retest effects showed that mean scores of repeat test takers were one-third of a standard deviation higher for the knowledge test and situational judgment test and one-half of a standard deviation higher for the cognitive ability test. The validity coefficients for the knowledge test differed significantly depending on whether examinees' test scores on the first versus second administration were used, with the latter being more valid. Analyses of between-person retest effects on the prediction of academic performance showed that the same test score led to higher levels of performance for those passing on the first attempt than for those passing on the second attempt. The implications of these results are discussed in light of extant retesting practice.     

DIMENSIONAL INTERPRETATION AND CONFIGURATION INVARIANCE IN MULTIDIMENSIONAL SCALING: AN EMPIRICAL STUDY

This paper is concerned with: a ) the invariance of nonmetric multi- dimensional scaling soludions over changes in stimulus domain; and b) pro- cedures for assisting the researcher in interpreting the axes of multidimen- sional scaling configurations. The stimuli consisted of the names of 17 popular brands of automobiles. Similarities and preference judgments were obtained from 37 subjects, divided into two groups of approximately equal size. Each group received 11 of the 17 stimuli. A core set of 6 stimuli was common over both groups. Each group also rated the 11 car models on 20 semantic differential scales. Results of the study suggested that the interpoint distances of bhe core set of 5 stimuli remained stable over subject groups and differences in stimulus set composition. Semantic differential ratings were used to find directions in the configurational space (obtained from overall similarity judg- ments) whose projections were maximally correlated with the outside (property) vectors. Stimulus configurations developed from the semantic differential space were highly congruent with those found by the analysis of direct similarity judgments. However, attempts to develop stimulus configurations by the "unfolding" of preference data alone did not lead to configurations which closely matched those found by the analysis of direct similarities data.     

OUTLIER DETECTION AND TREATMENT IN I/O PSYCHOLOGY: A SURVEY OF RESEARCHER BELIEFS AND AN EMPIRICAL ILLUSTRATION

Extreme data points, or outliers, can have a disproportionate influence on the conclusions drawn from a set of bivariate correlational data. This paper addresses two aspects of outlier detection. The results of a survey regarding how published researchers prefer to deal with outliers are presented, and a set of 183 test validity studies is examined to document the effects of different approaches to the detection and exclusion of outliers on effect size measures. The study indicates that: (a) there is disagreement among researchers as to the appropriateness of deleting data points from a study; (b) researchers report greater use of visual examination of data than of numeric diagnostic techniques for detecting outliers; and (c) while outlier removal influenced effect size measures in individual studies, outlying data points were not found to be a substantial source of variance in a large test validity data set.     

EMPIRICAL MINDFULNESS: TRADITIONAL CHINESE MEDICINE AND MENTAL HEALTH IN THE SCIENCE AND RELIGION DIALOGUE

As science and religion researchers begin to engage questions of mental health, mindfulness may prove to be a fruitful area of investigation. However, quantifying the physical effects of mindfulness on the brain is difficult because mindfulness deals with the problem of mental and physical interaction or, the mind/body problem. One system of understanding which may aid science and religion scholars in the pursuit of mindfulness is traditional Chinese medicine (TCM). Within TCM, heart Qi manages the body's present connection to time and space. If the “being in the moment” is disrupted, then the heart Qi is blocked and mental illness or various neurological disorders occur. Succinctly, within TCM, mindfulness is understood as a nonphysical phenomenon (Qi) which directly affects physical systems, resulting in empirical data. This is tracked and treated through the TCM understanding of Qi. The TCM view of Qi in mental health may therefore provide a helpful new paradigm to investigations concerning mindfulness and the human brain.
