Summary
Fixed-time (FT) schedules and extinction both decrease responding. FT schedules are more effective at reducing response rates when the reinforcer rate differs from the baseline schedule.
Area of Science:
- Behavioral psychology
- Operant conditioning
Background:
- Investigating reinforcement schedules is crucial for understanding behavior modification.
- Response-dependent schedules are common, but fixed-time (FT) schedules offer an alternative approach.
Observation:
- This study examined fixed-time (FT) schedules against a baseline response-dependent schedule and extinction.
- Arbitrary responses were used to evaluate schedule effectiveness.
Findings:
- Both FT schedules and extinction led to reduced responding.
- FT schedules demonstrated greater efficacy in decreasing response rates when the FT reinforcer rate was dissimilar to the baseline reinforcer rates.
- Data analysis explored adventitious response-reinforcer relations to explain these differences.
Implications:
- Findings suggest that manipulating reinforcer schedules, particularly the dissimilarity of FT schedules to baseline, can be a powerful tool for behavior reduction.
- This has implications for therapeutic interventions and understanding basic behavioral principles.

Reinforcement 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.

Timing 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...
