Document Summary
Two schedules of reinforcement: ratio type or interval type. With animals there is an interesting pattern in context of behavior with reinforcement. Vi 20- variable interval every 20 min the response is reinforced. Habituation- once u been reinforcement that drive is going to go down. Variable ratio- reinforcer delivered after a average of x number of responses. Produces high rate of behavior, with no pause after reinforcement. Vr 30- the response can come in 20 or 40 but the average of reinforcement is same 30. The behavior is going to be very steady over time. Fixed interval- reinforcer delivered for the first response that occurs after a fixed interval of time. Produces a low rate of behavior, with an on and off pattern. The response rate increases near the end of intervals. It is usually not chosen for a given behavior. Variable interval reinforcer delivered for the first response that occurs after a variable interval of time.
