Area of Science:

  • Behavioral psychology
  • Animal behavior studies

Background:

  • Pigeons were studied under a multiple schedule with varying reinforcement rates.
  • Understanding resistance to change is crucial in behavioral economics.

Purpose of the Study:

  • To test the behavioral momentum model's predictions in a multiple schedule.
  • To investigate how reinforcement in one component affects resistance to change in another.

Main Methods:

  • Eight pigeons were trained on a multiple variable-interval schedule.
  • Four resistance-to-change procedures were applied: prefeeding, full extinction, component extinction, and response-independent food.

Main Results:

  • Resistance to prefeeding and extinction decreased as the alternated component's reinforcement rate decreased.
  • Resistance to response-independent food was not affected by the alternated component's rate.
  • Maintaining reinforcement in the alternated component increased resistance to extinction in the constant component.

Conclusions:

  • The behavioral momentum model accurately predicted most results, particularly extinction and response-independent food.
  • The model's predictions aligned with the increased resistance to extinction when the alternated component was maintained.
  • Discrepancies in prefeeding data suggest areas for refinement in the behavioral momentum theory.
