Instrumental responding during extinction testing after the reinforcer was devalued (Paired groups) in an experiment by Bouton et al. (2020) described in the text. In the Control group, reinforcer devaluation had no effect on responding, indicating that the response was a habit. However, in the group given pre-feeding with an irrelevant food pellet just before the test (Pre-Feed), the response was an action again. Adapted from Bouton et al.
