Preference for fixed-interval schedules: effects of initial-link length.

G R Wardlaw, M C Davison

    Journal of the Experimental Analysis of Behavior
    |March 1, 1974
    PubMed
    Summary

    Pigeons showed a stronger preference for terminal-link schedules when initial-link schedules were shorter. This finding aligns with the Davison and Temple (1973) choice model, offering insights into behavioral economics.

    Area of Science:

    • Behavioral Psychology
    • Animal Cognition
    • Operant Conditioning

    Background:

    • Concurrent-chains schedules are used to study choice behavior in animals.
    • Understanding how pigeons choose between different reinforcement schedules is crucial for behavioral research.

    Purpose of the Study:

    • To investigate pigeon preference in concurrent-chains schedules with varied initial and terminal links.
    • To compare experimental data with predictions from different choice models.

    Main Methods:

    • Six homing pigeons were trained on concurrent-chains schedules.
    • Initial links used equal variable-interval schedules; terminal links used fixed-interval schedules.
    • Systematic variation of both initial- and terminal-link schedules.

    Main Results:

    • Pigeon preference increased as initial-link schedules became shorter.
    • Data strongly supported the Davison and Temple (1973) choice model.
    • Data did not align with two other tested choice models.

    Conclusions:

    • The study validates the Davison and Temple (1973) model for concurrent-chains performance.
    • An alternative analytical approach for concurrent-chains behavior was proposed.
    • Findings contribute to understanding decision-making processes in pigeons.
