    Pigeons

    Area of Science:

    • Behavioral science
    • Animal behavior

    Background:

    • Pigeons were studied under variable-interval schedules of reinforcement.
    • Previous research on open and closed economies yielded conflicting results.

    Purpose of the Study:

    • To investigate the behavioral effects of open and closed economies on pigeon behavior.
    • To determine if deprivation level influences the differences observed between economies.

    Main Methods:

    • Two experiments were conducted with pigeons under variable-interval schedules.
    • Response rates were measured in both open and closed economic conditions.
    • Deprivation levels were controlled in the second experiment.

    Main Results:

    • In a closed economy, response rates increased as reinforcement frequency decreased.

    Related Experiment Videos

  • In an open economy, response rates decreased for one pigeon and varied for another as reinforcement frequency decreased.
  • Differences between economies were not attributable to changes in deprivation level.

    • Conclusions:

    • Open and closed economies produce distinct behavioral effects in pigeons.
    • Reanalysis of prior studies supports the conclusion that economic conditions alter behavior.
