GUION and Gottier (1965) reviewed the results of a decade of research into the validity of personality tests for business and industry. They found that only 12 per cent of the reported validity coefficients were significantly different from zero. This exceeds the number to be expected by chance by only a small margin. None of these tests was found to be valid for a wide range of jobs. The authors concluded that "there is no generalizable evidence that personality measures can be recommended as good or practical tools for employee selection." This author's review confirmed the general dissatisfaction with personality measurement in business and industry. Personality measurements in personnel selection seem to be based upon two inadequate assumptions. First, they assume that there are global integrated forces within the individual which determine behavior in a wide range of varying and complex situations. This assumption conflicts with research findings on the generalization of behavior, which have shown that generalization occurs only when the stimuli are similar to those of the original learning situation. Second, personality measurements infer behavior tendencies from indirect evidence provided by the examinee's likes, opinions, or needs. Due in part to the abstract and highly general nature of personality constructs, measurements of them have tended to lack reliability and validity.The purpose of this review is threefold: (a) to present an approach to classifying and describing behavior styles which will serve as a foundation for further research in personnel psychology, (b) to describe a method of categorizing and defining job goals and performance activities which will serve cffectively in both the research and the applied functions of the personnel field, and (c) to identify tentatively the behavior 461 462 PERSONNEL PSYCHOLOGY styles which research has shown to be associated with effective performance.
Definitions and AssumptionsA number of definitions and related assumptions are essential in providing a foundation for classifying and describing behavior styles. These will be briefly discussed.The behavior style is the person's characteristic behaviors which occur in response to broad situations as perceived. These situations consist of a related constellation of external and/or internal stimuli. Not every behavior is included as a component of a style. I t is coinposed of those behaviors which recur with relative consistency in a given situation. The range of behaviors associated with a particular type of stimulus will be referred to as a behavior pattern. The behavior style for a person in a broad situation (such as a job) is defined in terms of specific, component behavior patterns. For the clinical setting, the situations involved are primarily social; for the industrial and business settings, they are work situations. The behavior style is described and measured through observations of overt behaviors and through verbal reports of past behaviors. This avoids the necessity for establishing highly gener...
