A Post-Reinforcement Pause (PRP) refers to a temporary cessation in behavior following the delivery of reinforcement. This phenomenon is prominently observed in operant conditioning, especially within fixed-ratio (FR) and fixed-interval (FI) schedules of reinforcement.
Historical Context
The concept of PRP was first identified and described by behaviorists, notably B.F. Skinner, in their studies of operant conditioning. Skinner’s extensive research into reinforcement schedules illustrated that after receiving a reward, an organism often exhibits a pause in the targeted behavior.
Types/Categories
-
Fixed-Ratio (FR) Schedules:
- In FR schedules, reinforcement is delivered after a set number of responses. PRP is commonly observed, with the length of the pause increasing with the ratio requirement.
-
Fixed-Interval (FI) Schedules:
- In FI schedules, reinforcement is available after a fixed period has elapsed since the last reinforcement. The PRP tends to occur right after the reinforcement and the rate of responding increases as the interval draws to a close.
Key Events and Explanations
- Observation in Laboratory Settings: Early experiments demonstrated PRPs in animals, such as pigeons and rats, under controlled conditions.
- Behavioral Interpretation: The PRP is believed to reflect a form of cost-benefit analysis by the organism, integrating the effort of responding with the expectancy of future reinforcement.
Mathematical Models and Diagrams
Behaviorists have modeled the PRP using reinforcement schedules to predict behavior patterns.

Importance and Applicability
Understanding PRPs is crucial for several reasons:
- Behavior Modification: Effective design of reinforcement schedules in educational and therapeutic settings.
- Workplace Incentives: Designing bonus and incentive structures.
- Understanding Habit Formation: Insights into how behaviors can be sustained or disrupted.
Examples
- Education: After a student receives a reward for completing a set of math problems, they may take a short break before starting another set.
- Workplace: An employee might take a brief pause after completing a task for which they receive a bonus.
Considerations
- Individual Differences: The length and occurrence of PRPs can vary among individuals.
- Task Complexity: More complex tasks might result in longer PRPs.
Related Terms
- Reinforcement: A stimulus that increases the probability of a behavior’s occurrence.
- Fixed-Ratio Schedule: A reinforcement schedule in which reinforcement is provided after a set number of responses.
- Fixed-Interval Schedule: A reinforcement schedule where reinforcement is given after a fixed time interval.
- Operant Conditioning: A learning process through which the strength of a behavior is modified by reinforcement or punishment.
Comparisons
- Variable-Ratio and Variable-Interval Schedules: These schedules do not typically show a PRP, as the uncertainty keeps the responding consistent.
Interesting Facts
- Pioneered by B.F. Skinner: The concept was deeply explored by B.F. Skinner, a key figure in behaviorism.
Inspirational Stories
- Applications in Education: Teachers have successfully used PRPs understanding to design classroom reward systems that maintain student engagement.
Famous Quotes
- B.F. Skinner: “Behavior is determined by its consequences.”
Proverbs and Clichés
- “Rest and Reward”: Highlights the natural pause that follows a reward or accomplishment.
Expressions, Jargon, and Slang
- “Taking a breather”: Informal expression that can be analogous to PRP in daily life.
FAQs
-
Q: What causes a post-reinforcement pause?
- A: It is caused by the receipt of reinforcement, leading to a temporary cessation in responding.
-
Q: Is PRP observed in all reinforcement schedules?
- A: No, it is typically observed in fixed-ratio and fixed-interval schedules.
-
Q: How long does a PRP last?
- A: The duration varies based on the individual and the task complexity.

Summary
The Post-Reinforcement Pause (PRP) is an essential concept in behavioral psychology that reflects the natural break in responding after a reinforcement.
