A study was conducted to investigate the application of the PLATO IV system to training interpersonal skills. Suitable content areas were chosen, and a mechanism to integrate various skill areas was designed. Training materials for this integration of skills were developed and coded into the PLATO IV system. A sample of experimental and control company commanders was tested and trained. Data about their on-the-job performance in the skill areas, as well as their companies' performance were collected and analyzed. It appears that the training had an effect on skill performance of company commanders, and indirectly on the attitudes and beliefs of their recruits. Less effect on company performance was observed, but there is evidence that the skill areas trained are related to success criteria used. The report includes 2 illustrations and 11 tables. Appendixes contain instructional material, questionnaires, and surveys. (Author/NR)
