Matching, maximizing, and the behavioral unit: concurrent reinforcement of response sequences
Journal of the Experimental Analysis of Behavior
|January 1, 1982
Summary
Pigeons
Area of Science:
- Behavioral science
- Animal behavior studies
- Cognitive psychology
Background:
- The study investigates choice behavior in pigeons within a probability matching framework.
- It examines how pigeons respond to sequences of key pecks under intermittent reinforcement schedules.
Purpose of the Study:
- To determine if pigeons treat response sequences as functional units in decision-making.
- To assess whether pigeons' choices align with matching theory predictions regarding reinforcement rates.
Main Methods:
- Pigeons were trained to peck two keys in a situation with four possible two-peck sequences (LL, LR, RL, RR).
- Reinforcement rates were manipulated across sequences in two phases, focusing on the first response (Phase 1) and response alternation (Phase 2).
- The intertrial interval between responses was also varied.
Main Results:
- The proportion of each response sequence emitted by pigeons matched the relative reinforcement rates for those sequences.
- However, individual key peck rates did not consistently match reinforcement rates.
- Changes in the intertrial interval influenced the frequency of different response sequences.
Conclusions:
- Response sequences function as integral units influencing choice, supporting a structural account of behavior.
- The observed matching between sequence output and reinforcement rates supports the principles of matching theory in this context.

01:21Operant Conditioning
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...

01:24Generalization, Discrimination, and Extinction
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...

01:24Reinforcement Schedules
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.

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 factor...

01:21Behavior Modification
Behavioral approaches have often been criticized for ignoring mental processes and focusing solely on observable behavior. However, these approaches provide an optimistic perspective for individuals seeking to change their behaviors. Rather than concentrating on intrinsic personality traits, behavioral approaches suggest that even longstanding habits can be modified by changing the reward contingencies that maintain them.

01:24Operant Conditioning Intervention
Operant conditioning serves as a foundational principle in therapeutic interventions aimed at modifying maladaptive behaviors. Central to this approach is the notion that behaviors, both adaptive and maladaptive, are learned through reinforcement. By analyzing the environmental factors that reinforce problematic behaviors, clinicians can design interventions to weaken these reinforcements and replace maladaptive behaviors with healthier alternatives.
