Delayed and current stimulus control in successive discriminations.

K G White

    Journal of the Experimental Analysis of Behavior
    |July 1, 1990
    PubMed
    Summary

    Discrimination in animal behavior weakens over time within a stimulus component. This is due to delayed control by the stimulus transition, impacting response patterns.

    Area of Science:

    • Behavioral Psychology
    • Animal Behavior
    • Operant Conditioning

    Background:

    • Successive discrimination tasks involve alternating stimuli signaling different reinforcement schedules.
    • Understanding stimulus control is crucial for analyzing animal behavior and learning.
    • Previous research indicates that stimulus transitions can influence responding.

    Purpose of the Study:

    • To investigate how stimulus control changes within a component of a successive discrimination task.
    • To determine the role of stimulus transitions in modulating discrimination over time.
    • To examine the impact of altering stimulus transitions on discriminative performance.

    Main Methods:

    • Utilized a successive discrimination procedure with alternating red and green hues.
    • Employed variable-interval schedules of reinforcement for each stimulus component.
    • Manipulated stimulus transitions by interpolating a white stimulus at different points within the component.

    Main Results:

    • Sensitivity to reinforcer ratio variations decreased systematically within each stimulus component.
    • This decrease in discrimination was attributed to delayed control by the preceding stimulus transition.
    • Interpolating a white stimulus at the component's end reduced initial discrimination, suggesting transition effects.

    Conclusions:

    • Discriminative control is not constant throughout a stimulus component; it diminishes over time.
    • The transition between discriminative stimuli exerts a delayed influence on responding, affecting the early part of the subsequent component.
    • Modifying stimulus transitions can alter the temporal dynamics of stimulus control in successive discrimination.
