Choice, changing over, and reinforcement delays.

Area of Science:

• Behavioral psychology
• Animal behavior studies

Background:

• Concurrent schedules of reinforcement are common in animal behavior research.
• Understanding delays to reinforcement is crucial for predicting choice behavior.

Purpose of the Study:

• To investigate the independent effects of two delays associated with switching between variable-interval schedules.
• To determine how these delays influence pigeons' switching behavior.

Main Methods:

• Three experiments using pigeons exposed to concurrent variable-interval schedules.
• Manipulating changeover delay and travel time requirements.
• Analyzing changeover rates as a function of different delay parameters.

Main Results:

• Changeover rates decreased as a negative power function of the total obtained delay.
• The delay following a stimulus change had a minor effect on overall changeover rates.
• Post-changeover responding patterns were influenced by the stimulus-change-to-reinforcer delay.

Conclusions:

• The total obtained delay is the primary driver of changes in switching behavior.
• The immediate stimulus-change-to-reinforcer delay influences the pattern of responding after a switch.
• Findings contribute to understanding choice and reinforcement in behavioral economics.
