Component duration and relative response rates in multiple schedules.

J C Todorov

    Journal of the Experimental Analysis of Behavior
    |January 1, 1972
    PubMed
    Summary

    Pigeons trained on mixed schedules showed higher response rates on the shorter variable-interval 30-sec schedule. This rate difference was most pronounced with brief exposure durations, deviating from matching predictions.

    Area of Science:

    • Behavioral Psychology
    • Animal Behavior Studies

    Background:

    • Operant conditioning involves schedules of reinforcement.
    • Multiple schedules present different reinforcement contingencies sequentially.

    Purpose of the Study:

    • Investigate pigeon response rates under mixed variable-interval schedules.
    • Examine the effect of component duration on relative response rates.

    Main Methods:

    • Pigeons trained on alternating variable-interval 30-sec and 90-sec schedules.
    • Component presentation duration varied from 5 to 300 seconds.
    • Response rates in each component were recorded and compared.

    Main Results:

    • Response rate was consistently higher in the variable-interval 30-sec component.
    • The discrepancy in response rates was greatest with shorter component durations.
    • Proportion of responses in the 30-sec component ranged from 0.60 to 0.71, below matching predictions.

    Conclusions:

    • Component duration significantly influences relative response rates in mixed schedules.
    • Pigeon behavior deviates from strict matching rules under these conditions.
    • Findings align with previous research on schedule-controlled behavior.
