    Rats showed different responses to avoidance learning. When shock omission was possible, rats adjusted behavior, but when shock followed responses, some ignored punishment, responding as if shock was noncontingent.

    Area of Science:

    • Behavioral neuroscience
    • Animal learning and behavior

    Background:

    • Avoidance learning is crucial for understanding fear and anxiety.
    • Partial avoidance contingencies, where not all aversive events are omitted or punished, offer insights into behavioral flexibility.

    Purpose of the Study:

    • To investigate the behavioral asymmetry between omission and punishment probabilities in partial avoidance learning.
    • To determine how rats respond to varying probabilities of shock omission versus shock punishment.

    Main Methods:

    • Rats were trained on a discrete-trial avoidance task.
    • Two groups were tested: one with varying omission probabilities (rho(00)>0) and another with varying punishment probabilities (rho(11)>0).
    • Shock delivery was contingent on response or non-response at the end of each trial cycle.

    Main Results:

    • Subjects in the omission group showed graded decrements in responding as omission probability increased, matching nonresponse rates to shock omission probability.
    • Subjects in the punishment group exhibited varied responses; some decreased responding with increased punishment, while others continued responding even with inevitable shock.
    • These findings reveal an asymmetry in how rats learn under different partial avoidance contingencies.

    Conclusions:

    • Behavioral control is asymmetric between omission and punishment dimensions in partial avoidance.
    • Rats demonstrate sensitivity to omission probability, adjusting responding to match shock likelihood.
    • Sensitivity to punishment probability is more variable, with some individuals exhibiting control by overall shock frequency rather than contingency.
