Preference for mixed versus constant delay of reinforcement.
Journal of the Experimental Analysis of Behavior
|March 1, 1976
Summary
Pigeons showed a preference for mixed delays over constant delays in reinforcement schedules. This preference for variable reinforcement timing increased with a wider range of delay intervals.
Area of Science:
- Behavioral psychology
- Animal behavior studies
- Operant conditioning
Background:
- Reinforcement schedules are fundamental to understanding behavior.
- The impact of delay of reinforcement on choice behavior is a key area of study.
- Previous research has explored preferences for different delay patterns.
Purpose of the Study:
- To investigate pigeon preference between constant and mixed delay of reinforcement.
- To determine how the range of delay variability influences this preference.
- To contribute to the understanding of choice behavior under variable reinforcement.
Main Methods:
- Concurrent equal variable-interval schedules were employed.
- Pigeons (N=6) were trained to peck keys for food reinforcement.
- Different constant and mixed delay schedules were systematically presented.
Main Results:
- Pigeons consistently preferred mixed delay schedules over constant delay schedules.
- Preference for mixed delays intensified as the variability range of the delay intervals widened.
- Individual differences in preference were observed.
Conclusions:
- Mixed delays of reinforcement are generally preferred over constant delays in pigeons.
- The degree of variability in delay intervals significantly modulates this preference.
- Findings have implications for reinforcement theory and behavioral economics.
