Intermittent Reinforcement
A reinforcement schedule where responses are rewarded only some of the time, often producing more persistent and resistant-to-extinction behaviors than continuous reinforcement.
Intermittent Reinforcement
Intermittent reinforcement represents a sophisticated component of operant conditioning where behavioral responses are reinforced on a partial rather than continuous basis. This pattern of irregular reinforcement creates particularly strong and persistent behavioral patterns, often referred to as the "partial reinforcement effect."
Core Mechanisms
Fundamental Principles
- Irregular reward delivery
- Variable timing or ratio patterns
- Enhanced behavioral persistence
- Greater resistance to extinction
Schedule Types
Variable Ratio (VR)
- Reinforcement based on average number of responses
- Unpredictable reward delivery
- Creates high, steady response rates
- Common in gambling behavior
Fixed Ratio (FR)
- Reinforcement after specific number of responses
- Predictable reward pattern
- Linked to work motivation
- Creates burst-pause response patterns
Variable Interval (VI)
- Time-based random reinforcement
- Moderate, steady response rates
- Applications in monitoring behavior
Fixed Interval (FI)
- Time-based predictable reinforcement
- Creates scalloped response patterns
- Related to temporal learning
