Examples of Delayed Reinforcer vs Immediate Reinforcers
- We may be inclined to engage in small immediate reinforcers
- (watching TV) rather than large delayed reinforcers (getting an A in a course)
- which require consistent study.
Reinforces the desired response each time it occurs
- Reinforces a response only part of the time. Though
- this results in slower acquisition in
- the beginning, it shows greater resistance to extinction later on.
The _____ or _____, comes
with a bar or key that an animal manipulates to obtain a reinforcer like food
or water. The bar or key is connected to devices that record the animal’s
operant chamber, or Skinner box
guide behavior towards the desired target behavior through successive approximations.
Reinforces the desired response each time it occurs.
Reinforces a response only part of the time. Though this results in slower acquisition in the beginning, it shows greater resistance to extinction later on.
- a response only after a specified number of responses. e.g., piecework pay.
After reward, brief pause, then returns to high rate
- Reinforces a response after an unpredictable number of responses. This is hard to extinguish because of the unpredictability. (e.g., behaviors like gambling,
Reinforces a response only after a specified time has elapsed Increases responses as the anticipated time draws near (e.g., checking mail)
- Reinforces a response at unpredictable time intervals, which produces slow, steady responses. Slow, steady responding (never know when…)
An aversive event that decreases the behavior it follows.
