WRITTEN TO PROVIDE INVESTIGATORS OR ADMINISTRATORS WITH A REVIEW OF THE PROBLEMS OF PLANNING, CONDUCTING, OR INTERPRETING STUDIES IN HUMAN RELATIONS TRAINING, THIS PAPER DISCUSSES RESEARCH PROBLEMS AND WAYS TO OVERCOME THEM. PROBLEMS OF SELECTION OF CONTROL GROUPS, TEMPORAL CHANGE IN TRAINING OUTCOME, DESIGN RESTRICTIONS IN OBSERVATION OF EXPERIMENTAL OUTCOME, TIMING OF DATA COLLECTION, EXPERIMENTER-PARTICIPANT RELATIONSHIPS IN LABORATORY SETTINGS, AND STATISTICAL MEASUREMENT ARE REVIEWED. AMONG THE SUGGESTIONS FOR RESEARCH IMPROVEMENT ARE--TO STUDY THE PROCESS OF TRAINING AS WELL AS THE OUTCOME (FOR MOST VOLUNTEERS DIFFER SIGNIFICANTLY FROM NON-VOLUNTEERS, THE LATTER SHOWING A HIGHER DEGREE OF RESISTANCE AND MISTRUST AFFECTING RESULTS), TO EXTEND OBSERVATION OF TRAINING OUTCOME OVER A LONGER PERIOD OF TIME (CHANGE IN BEHAVIOR CAN BE PROGRESSIVE AND SIGNIFICANT), AND TO INVOLVE THE EXPERIMENTER MORE WITH THE PARTICIPANTS (TO OVERCOME THE STERILE ATMOSPHERE OF THE TEST SITUATION WHICH AFFECTS PARTICIPANT ATTITUDE).
