This study examined if the rate of conditioned reinforcement independently affects choice in pigeons. Results suggest that increasing conditioned reinforcement rate in concurrent-chains schedules may not independently influence choice behavior.

Area of Science:

  • Behavioral psychology
  • Animal behavior studies
  • Learning theory

Background:

  • Delay-reduction theory, a prominent model in behavioral psychology, may overlook the impact of conditioned reinforcement rate.
  • Concurrent-chains schedules involve initial and terminal links, where conditioned reinforcement occurs in the terminal link.

Purpose of the Study:

  • To investigate whether the rate of conditioned reinforcement has an independent effect on choice behavior in pigeons.
  • To test predictions derived from delay-reduction theory regarding the influence of conditioned reinforcement rate on choice.

Main Methods:

  • Pigeons were trained on modified concurrent-chains and concurrent-tandem schedules.
  • Manipulations were made to the initial link duration to alter the rate of conditioned reinforcement in chain schedules but not tandem schedules.

Main Results:

  • In concurrent-chains schedules, shortening the initial link increased the rate of conditioned reinforcement.
  • Choice behavior in pigeons was consistent with delay-reduction theory predictions, indicating that conditioned reinforcement rate may not have an independent effect on choice.

Conclusions:

  • The findings suggest that the rate of conditioned reinforcement might not independently influence choice in concurrent-chains schedules.
  • Behavioral psychology models may need refinement to fully account for the interplay of reinforcement variables in decision-making.
