Graphical Representation of Reinforcement Schedules

The effects of different reinforcement schedules can be visualized on a graph plotting the cumulative number of responses against time. On such a graph, ratio schedules (Variable and Fixed) exhibit steep slopes, indicating high response rates, while interval schedules (Variable and Fixed) show more moderate slopes. Variable schedules produce steady, relatively straight response lines. In contrast, fixed schedules create distinct patterns: the fixed ratio schedule is marked by a brief pause after each reinforcement before responding resumes at a high rate, creating a 'stair-step' pattern. The fixed interval schedule produces a 'scalloped' curve, where the response rate is low immediately after reinforcement and gradually increases as the next reinforcement time approaches.
