    Rats showed significant positive contrast effects when a competing wheel-running response was introduced during lever pressing for food. This suggests that behavioral contrast may result from reallocating responses between different activities when reinforcement changes.

    Area of Science:

    • Behavioral neuroscience
    • Animal behavior studies
    • Operant conditioning research

    Background:

    • Behavioral contrast is a phenomenon where changes in reinforcement for one response affect the rate of another response.
    • Previous research has explored both positive and negative contrast effects in various animal models.

    Purpose of the Study:

    • To investigate the impact of a competing wheel-running response on lever-pressing behavior in rats under food reinforcement.
    • To explore the underlying mechanisms of positive and negative behavioral contrast.

    Main Methods:

    • Rats were trained to press a lever for food reinforcement.
    • A competing wheel-running response was introduced as an alternative activity.
    • Behavioral changes, specifically lever-pressing rates, were measured.

    Main Results:

    • Rats exhibited large positive-contrast effects, meaning lever-pressing increased when wheel-running was available.
    • The findings suggest a reallocation of responses between lever-pressing and wheel-running.

    Conclusions:

    • Positive and negative behavioral contrast may arise from the reallocation of competing interim and terminal responses.
    • Changes in reinforcement conditions in one component of a schedule can influence behavior in other components.
