A SERIES OF STUDIES WERE MADE ON THE EFFECTS OF LABORATORY TRAINING IN HUMAN RELATIONS ON THE ORGANIZATIONAL BEHAVIOR OF "MIDDLE" MANAGERS. THROUGH REPEATED FACTOR ANALYSIS, THE ORGANIZATIONAL BEHAVIOR DESCRIBER SURVEY (OBDS) WAS DEVELOPED BY WHICH A MANAGER AND HIS ASSOCIATES COULD DESCRIBE HIS BEHAVIOR. THE OBDS PERMITTED RATINGS ON RATIONAL-TECHNICAL COMPETENCE, VERBAL DOMINANCE, CONSIDERATION, AND EMOTIONAL EXPRESSIVENESS. STUDIES OF 357 MANAGERS IN FOUR POPULATIONS SHOWED NO SIGNIFICANT CHANGES IN ORGANIZATIONAL BEHAVIOR FOLLOWING TRAINING. THERE WERE, HOWEVER, POSITIVE RELATIONSHIPS BETWEEN INVOLVEMENT IN THE LABORATORY AND INCREASES ON THE CONSIDERATION SCALE. THERE WERE SMALL CORRELATIONS BETWEEN BEHAVIOR IN THE ORGANIZATION AND IN THE TRAINING LABORATORY. DETERMINANTS OF ORGANIZATIONAL BEHAVIOR SEEMED TO BE SITUATIONAL, AND INDICATIONS WERE THAT STRONG BARRIERS TO THE TRANSFER OF ATTITUDES FROM THE TRAINING LABORATORY TO THE ORGANIZATION MAY EXIST. THE FINDINGS ALSO SUGGESTED THAT TRAINING MAY LEAD TO MULTIDIMENSIONAL AND MULTIDIRECTIONAL CHANGES. THE DOCUMENT INCLUDED SAMPLE QUESTIONS, TABLES OF CORRELATIONS, AND 13 REFERENCES. (AJ)
