THIS STUDY SOUGHT TO IDENTIFY VARIABLES RELATED TO EFFECTIVENESS OF COMMUNICATION IN MILITARY OPERATIONS. THE GOAL WAS TO DEVELOP TESTS TO CLASSIFY OFFICERS AND AIRMEN, BASED UPON ALL OF THE BROAD COMMUNICATION ABILITIES NEEDED IN THE AIR FORCE. THE RESEARCH OUTLINE CONSISTED OF REVIEWING COMMUNICATION STUDIES AND OTHER TESTS, PREPARING A REDUCED BATTERY, AND ANALYZING THE DATA. THESE BATTERIES OF SCORES WERE USED--(1) BATTERY A (APTITUDE TEST SCORES), (2) BATTERY B (PERSONALITY AND SELF-REPORT SCORES), AND (3) BATTERY C (PREDICTOR AND SITUATIONAL CRITERION SCORES). SEVERAL HYPOTHESES WERE DRAWN PERTAINING TO EXISTING MEASURES AND INVOLVING NEW INTELLIGENCE AND PERSONALITY MEASURES. THE RESULTS INDICATE THAT MANY MEASURING DEVICES COULD BE IMPROVED. COMMUNICATION ABILITIES ARE HIGH-LEVEL SKILLS UNDERLYING MANY IMPORTANT ACTIVITIES AND COMPRISING A VAST AREA INVOLVING A LARGE NUMBER OF VARIABLES. AS A RESULT OF THIS STUDY, A STANDARD SET OF COMMUNICATION ABILITIES AND TRAITS WHICH UNDERLIE SUCCESSFUL PERFORMANCES ACROSS TYPICAL COMMUNICATION TASKS IN AN ORGANIZATION WERE IDENTIFIED. (PH)
