Abstract
The current article concerns human outcome - selective Pavlovian - instrumental transfer (PIT), where Pavlovian cues selectively invigorate instrumental responses that predict common rewarding outcomes. Several recent experiments have observed PIT effects that were insensitive to outcome devaluation manipulations, which has been taken as evidence of an automatic “associative” mechanism. Other similar studies observed PIT effects that were sensitive to devaluation, which suggest s a more controlled, goal - directed process. Studies supporting the automatic approach have been criticised for using a biased baseline, while studies supporting the goal - directed approach have been criticised for priming multiple outcomes attest. The current experiment addressed both of these issues. Participants first learned to perform two instrumental responses to earn two outcomes each (R1 - O1/ O3, R2 - O2/ O4), before four Pavlovian stimuli (S1 - S4) were trained to predict each outcome. One outcome that was paired with each instrumental response (O3 and O4) was then devalued, so that baseline response choice at test would be balanced. Instrumental responding was then assessed in the presence of each individual Pavlovian stimulus, so that only one outcome was primed per trial. PIT effect s were observed for the valued outcomes , t s > 3.99, p s < .001, but not for the devalued outcomes , F < 1 , BF 10 = 0.29. Hence, when baseline response choice was equated and only one outcome was primed per test trial, PIT was sensitive to outcome devaluation. The data therefore support goal - directed models of PIT.
