Area of Science:

Behavioral psychology
Animal behavior

Background:

Concurrent schedules of reinforcement are fundamental in behavioral psychology.
Understanding choice behavior in pigeons provides insights into decision-making processes.

Purpose of the Study:

To investigate pigeon choice behavior between a simple variable-interval (VI) schedule and a chained VI-VI schedule.
To analyze how reinforcement rates influence responding under concurrent schedules.

Main Methods:

Pigeons were trained on a two-key concurrent schedule.
One key offered food via a simple VI schedule; the other via a chained VI-VI schedule.
Response rates were compared against local and overall reinforcement rates.

Main Results:

Related Experiment Videos

Pigeons responded more on the simple schedule during the chain's initial link.

Pigeons responded more on the chain schedule during its terminal link.

Overall chain responding was not directly proportional to overall chain reinforcement.

Conclusions:

Pigeon choice behavior is influenced by the schedule's phase (initial vs. terminal link).
Responding on chained schedules is a byproduct of responding during different link phases, not solely overall reinforcement.
