A computer program for programming schedules of reinforcement is described. Students can use the program to experience schedules of reinforcement that are typically used with nonhuman subjects. A cumulative recording of a student's responding can be shown on the screen and/or printed with the computer's printer. The program can also be used to program operant schedules for animal subjects. The program was tested with human subjects experiencing fixed ratio, variable ratio, fixed interval, and variable interval schedules. Performance for human subjects on a given schedule was similar to performance for nonhuman subjects on the same schedule.
