PSYC 2600 Final: PSYC 2600 Finals Notes
Document Summary
Intermittent schedules: two dimensions, 1. number of responses required for reinforcement [ratio schedule, 2. passage of time since last reinforcement [interval schedule] Fixed ratio: reinforcement after emitting a fixed number of responses. (every 20 responses = reward) Initially very motivated, then there is a pause before the certain behaviour begins: when we increase the interval, more pauses before they start doing the behaviour again. Variable ratio: reinforcement comes after an average number of responses. (on average every. 20th response = reward: very high levels of response, no pauses. Fixed interval: reinforcement follows 1st response after a specified period of time. (first response after 20 seconds = reward) Initially there is a lot of response: more responses near the end of the time. Variable interval: reinforcement follows the first response made after a variable period of time. (on average, first response after 20 seconds: high resistance to extinction, no pauses, low steady rate of responding.
