Summary
This study quantifies reinforcement as induction using a power function, integrating it with matching law theory. It explains pigeon behavior under variable schedules, particularly how peck rates change with reinforcer rates.
Area of Science:
- Behavioral psychology
- Animal behavior studies
- Quantitative analysis of behavior
Background:
- Reinforcement can be conceptualized as induction, quantifiable by a power function of reinforcer rate.
- Previous models assumed constant background activities (BO) and reinforcers (ro), but these vary with BO.
- Power-function induction suggests that BO should fluctuate with reinforcer rate.
Purpose of the Study:
- To quantify reinforcement as induction using a power function.
- To integrate this concept with matching law theory.
- To account for pigeon behavior under variable schedules based on reinforcer rates.
Main Methods:
- Utilized data from Baum (1993) on pigeon performance under variable-ratio (VR) and variable-interval (VI) schedules.
- Analyzed peck rates in relation to varying food (reinforcer) rates.
- Developed a model based on competition between induced pecking and background activities (BO).
Main Results:
- Pigeon VR peck rates showed an inverted U-shaped relation with food rate.
- Pigeon VI peck rates exhibited a three-range pattern (low-to-moderate, moderate-to-high, extremely high) with an inflection point.
- A competition model explained VI peck rates in moderate to extreme food rate ranges.
Conclusions:
- Power-function induction provides a quantifiable link between reinforcement and behavior.
- The model successfully accounts for complex peck rate patterns under VI schedules.
- Future research aims to integrate power-function induction with matching theory for a comprehensive explanation.

Positive reinforcement is a powerful method for teaching new behaviors to both animals and humans. B.F. Skinner demonstrated this with his experiments using rats in a Skinner box. When a rat pressed a lever, it received a food pellet. This immediate reward encouraged the rat to repeat the behavior. This method, where a reward follows every instance of the behavior, is known as continuous reinforcement. It is highly effective for establishing new behaviors quickly.

Operant conditioning, a key concept in behavioral psychology, involves using reinforcement and punishment to alter the likelihood of a behavior being repeated. B.F. introduced this type of conditioning. Skinner focused on voluntary behaviors and the consequences that follow them, influencing whether these behaviors will be strengthened or diminished.
Reinforcement in operant conditioning can be positive or negative, both of which serve to increase the likelihood of a behavior. Positive...

Generalization, discrimination, and extinction are key concepts in operant conditioning that influence how behaviors are learned and maintained.
Generalization occurs when a behavior reinforced in one context is performed in similar situations. For instance, a student who studies diligently for calculus and receives excellent grades might apply the same study habits to psychology and history, expecting similar results. Generalization shows how learning in one setting can influence behavior in...

01:08Timing and Consequences on Behavior

In operant conditioning, the timing of reinforcement is crucial. For animals like rats and cats, immediate reinforcement (within a few seconds) is much more effective than delayed reinforcement. For example, a food reward for a rat needs to follow within 30 seconds of pressing a bar to be effective.
Humans, however, can respond to delayed reinforcers. We often make decisions between immediate small rewards and delayed larger rewards. This ability to delay gratification is a significant...

B.F. Skinner, a prominent figure in behavioral psychology, introduced operant conditioning by emphasizing the role of consequences in shaping behavior. This theory builds upon the law of effect proposed by Edward Thorndike, which posits that behaviors followed by satisfying outcomes are likely to be repeated. In contrast, those followed by unsatisfying outcomes are less likely to recur.

01:19Role of Shaping in Operant Conditioning
1.3K
Shaping is a technique used in operant conditioning to train complex behaviors by rewarding successive approximations toward the target behavior. This method is necessary because organisms are unlikely to perform complex behaviors spontaneously. Instead, shaping breaks down the desired behavior into small, manageable steps.
The steps involved in shaping begin with reinforcing any response that resembles the desired behavior. For example, parents might praise a child for picking up one toy. As...
