N2 - Outcome-selective Pavlovian-instrumental transfer (PIT) refers to the finding that presenting Pavlovian predictors of outcomes can enhance the vigor of instrumental responding for those same outcomes. Three experiments examined the sensitivity of outcome-selective PIT to Pavlovian (stimulus-outcome) extinction. In Experiment 1, participants first learnt to perform different instrumental responses to earn different outcomes. In a separate Pavlovian training phase, certain stimuli were established as Pavlovian signals of the different outcomes. Some of these Pavlovian stimuli were then extinguished (they were presented alone, without any outcome), while others were not. A final transfer test measured the extent to which these Pavlovian cues biased instrumental response choice. Consistent with previous work, the observed PIT effects were immune to Pavlovian extinction; the non-extinguished and extinguished cues produced PIT effects that did not significantly differ in size. In Experiment 2, response choice was tested in the presence of compound stimuli that included both extinguished and non-extinguished cues. Response choice was highly sensitive to the extinction manipulation under these circumstances. Experiment 3 tested whether this sensitivity to Pavlovian extinction was a direct effect of the associative strength of the Pavlovian cues present, or an indirect effect of cue salience. The results provide unique evidence to suggest that PIT is a direct consequence of the strength of the Pavlovian associations. (PsycInfo Database Record (c) 2020 APA, all rights reserved)
