Job Satisfaction Researches of 1964–65

This annual review of job satisfaction researches is the 23rd in a series and covers reports published in 1964–65 plus earlier studies not previously dealt with in this journal. The format—findings and conclusions, topics investigated, per cent dissatisfied, current emphases, and summaries of studies—has become standard in this series of articles.     

Problems of Work Evaluation

In reviewing the history of the development of techniques of work evaluation, four different approaches are appraised: (1) the mental testing approach, (2) the job analysis approach, (3) the work-sample approach, and (4) the situational assessment approach. Each of these sets of methods is found to arise from somewhat different sectors of society, to serve differing interests, and to have differing objectives. After examination of the merits and limitations of each of the four approaches, the conclusion is drawn that “no one of these four methods can do everything; each deals with a restricted facet of a many-faceted problem.” Attention is called to the general need for validation through professional observation in unprotected industrial settings.     

Saturation of red: A prothetic continuum

A battery of procedures was used to scale the saturation of colors produced by mixtures of red and gray papers. By direct magnitude estimation, the apparent saturation was found to grow as the1.7 power of the percentage of red in the mixture. The power law was confirmed by the cross-modality matching of loudness to saturation. The inverse continuum, paleness, was also scaled. Saturation appears to be a prothetic continuum because the category scale is curved and the subjective size of the jnd increases as saturation increases.     

Regression effect in psychophysical judgment

Psychophysical judgment, like all other kinds of judgment, involves a matching or equating of two different domains. When the judgment involves the matching of values on two perceptual continua, the observer tends, on the average, to constrict the range of his adjustments on whichever variable is placed under his control. When the observer adjusts each variable in turn, two different regression lines are produced. This regression effect presumably occurs whenever the results of the matching judgments yield less than a perfect correlation. Illustrative examples are given for the continua, loudness, vibration, brightness, and duration.
