  • Title: Suppression of operant vs consummatory behavior.
    Author: DeCosta MJ, Ayres JJ.
    Journal: J Exp Anal Behav; 1971 Jul; 16(1):133-42. PubMed ID: 5142387.
    Abstract:
    The magnitude and variability of conditioned suppression of bar pressing and dipper licking were compared. In two steady-state experiments, suppression of bar pressing was more profound and more stable from day to day. The two measures of suppression were uncorrelated as indexed by Pearson product-moment correlation coefficients computed for adjacent trials. Correlations within measures (internal consistency) were somewhat higher for the bar-press system except when a high proportion of rats completely suppressed on one of the correlated trials. In a transient state experiment in which possible adventitious punishment of both response systems was eliminated, suppression of bar pressing was again more profound and considerably slower to extinguish.
