Fixation produced by conflict.

E B Karsh

    Science (New York, N.Y.)
    |May 15, 1970
    PubMed
    Summary

    Rats developed position fixations when faced with a conflict choice. However, rats learned to choose the rewarded option when presented with a non-rewarded alternative during reversals.

    Changes in Intensity of Punishment: Effect on Running Behavior of Rats.

    Science (New York, N.Y.)·1963

    Area of Science:

    • Behavioral Neuroscience
    • Animal Cognition

    Background:

    • Decision-making under conflicting outcomes is complex.
    • Understanding animal learning strategies is crucial for cognitive research.

    Purpose of the Study:

    • To investigate how rats' choices are affected by conflicting reward and punishment signals.
    • To compare learning in reversal tasks with different outcome contingencies.

    Main Methods:

    • Rats were presented with two alternatives: one rewarded and one with conflicting outcomes (rewarded/punished).
    • A second group received a rewarded alternative versus a non-rewarded alternative.
    • Both groups underwent successive reversals of alternative positions.

    Main Results:

    • Rats in the conflict condition developed position fixations upon reversal.
    • Rats in the non-rewarded condition consistently chose the rewarded alternative across 25 reversals.

    Conclusions:

    • Conflicting outcomes impair adaptive choice behavior in rats.
    • Rats can learn to discriminate and consistently choose rewarded options when punishment is absent.
