Behavior-dependent reinforcer-rate changes in concurrent schedules: A further analysis.

M Davison, B Alsop

    Journal of the Experimental Analysis of Behavior
    |July 1, 1991
    PubMed
    Summary

    Pigeons trained on concurrent schedules showed that behavior-dependent reinforcer rates, unlike independent ones, influenced choices. Models must account for local reinforcer rate discrimination and emergent contingencies.

    Area of Science:

    • Behavioral Psychology
    • Operant Conditioning
    • Animal Behavior

    Background:

    • Concurrent variable-interval schedules are used to study choice behavior.
    • Existing models often assume non-discrimination of local reinforcer rates.
    • The role of behavior-contingent reinforcer rates in choice is not fully understood.

    Purpose of the Study:

    • To investigate how behavior-dependent versus independent reinforcer rates affect choice in pigeons.
    • To test the ability of current performance models to account for observed data.
    • To explore the influence of emergent contingencies on undermatching.

    Main Methods:

    • Six pigeons were trained on concurrent variable-interval schedules under three procedures: standard concurrent, dependent (behavior-contingent), and independent.

  • The dependent and independent procedures involved time windows (5s to 60s, and 240s in dependent only) where reinforcer rates varied.
  • Response rates and reinforcer frequencies were systematically manipulated and recorded.

    • Main Results:

    • Pigeon performance was similar between concurrent and independent procedures.
    • The dependent procedure significantly affected performance, particularly with shorter time windows (under 30s).
    • Undermatching was observed, potentially due to emergent contingencies.

    Conclusions:

    • Models assuming non-discrimination of local reinforcer rates fail to explain the data.
    • Current models are insufficient to explain the effects of contingencies between response alternatives.
    • Emergent contingencies arising from time allocation likely contribute to undermatching.
