Document Summary
Unit 3 objectives: know the common simple schedules of reinforcement and how reinforcement is arranged for each (crf, fr, fi, vr, vi, pr) Simple schedules of positive reinforcement: interval schedules: require a response, time component, ratio schedules: response dependent, no time component, continuous reinforcement (crf): a schedule of reinforcement where every response produces the reinforcer. Intermittent produces more response variability: fixed ratio (fr) schedules. Fixed ratio: the last of a specified number of responses is reinforced (the number is always the same: response dependent, complete 20 lever presses (fr 20)! get a food pellet, key features of patterning, high rate of responding. The harder you work, the longer you pause. Possible ratio strain (schedule requirement is too big, causes big pauses during run )! going from 5 lever presses to 100, rat won"t press lever 100 times. Progressive ration: the number of r required for reinforcers increases (or decreases) after each reinforce delivery.
