Transition between habits and goal-directed actions in the renewal effect.

Abstract

Three experiments with rats explored whether previously extinguished goal-directed and habitual responding recover with the same status using an ABA renewal preparation. In Experiments 1a and 1b, a lever-press response was minimally (four sessions) or extensively (16 sessions) trained in one context (Context A) and extinguished in another context (Context B). Then, outcome devaluation took place in either Context A or Context B in which a food pellet reinforcing the response was paired with lithium chloride (LiCl) for devalued groups and with saline for a control group. Finally, renewal of the extinguished response was tested in both Contexts A and B. We confirmed that both minimally and extensively trained responses renewed as goal-directed action regardless of the context in which devaluation took place. This finding was replicated in Experiment 2 even after more extended acquisition training (32 sessions). However, another group that received outcome devaluation before but not after extinction training showed habitual performance during extinction training as well as in a subsequent renewal test. Experiment 3 replicated these results and confirmed that renewal of goal direction for rats that received extinction training immediately prior to outcome devaluation was not an artifact of consecutive LiCl exposures over a short period of time in Experiments 1 and 2, using a more reliable devaluation protocol. Overall, the present results extend previous findings suggesting that actions and habits renew with the same status by returning to the original context after extinction. The most critical finding is the differential effects of pre- and postextinction devaluation on the expression of habitual behavior; extinction prior to devaluation may convert a habitual performance into a goal-directed action. This novel finding is discussed in relation to recent studies that identified several factors contributing to a transition from habitual to goal-directed control of instrumental behavior.
