Graded differential reinforcement: Response-dependent reinforcer amount.

G D Gentry, R T Eskew

    Journal of the Experimental Analysis of Behavior
    |January 1, 1984
    PubMed
    Summary

    Correlated reinforcement, where reinforcer duration depends on responses, maintained higher key pecking rates in pigeons than constant reinforcement. This suggests differential reinforcement explains the observed behavior in pigeons.

    Area of Science:

    • Behavioral Psychology
    • Animal Behavior Studies

    Background:

    • Autoshaping establishes key pecking in pigeons.
    • Reinforcement schedules influence operant behavior.

    Purpose of the Study:

    • To investigate the effect of correlated reinforcement on pigeon key pecking.
    • To compare correlated reinforcement with automaintenance and yoked control procedures.

    Main Methods:

    • Six pigeons were trained using autoshaping for key pecking.
    • Correlated reinforcement: reinforcer duration varied with response count.
    • Control conditions: automaintenance (constant reinforcer) and yoked controls (response-independent/dependent).

    Main Results:

    • Correlated reinforcement maintained higher response rates compared to control conditions.

    Related Experiment Videos

  • Pigeon key pecking was significantly influenced by the response-dependent reinforcer duration.

    • Conclusions:

    • Differential reinforcement effectively explains the maintained response rates under the correlated schedule.
    • Response-dependent reinforcement schedules can enhance operant behavior in pigeons.
