The research reported here was initiated and designed to assess the impact of various schedules of incentive delivery (schedules of reinforcement) on performance and attitudes in an Air Force-related setting. Civilian subjects matching the characteristics of Air Force trainees were hired to work for four weeks, one week under each of four schedules of reinforcement: salary, fixed ratio, variable ratio, and variable ratio-variable amount. The results indicated that the salary schedule resulted in the lowest performance and attitudes. Performance was best under the variable ratio-variable amount schedule, while attitudes were best under the fixed ratio schedule. It was concluded that instituting a fixed or variable ratio-variable amount schedule of incentive delivery would be a highly cost-effective procedure in computer managed Air Force training.
