Two experiments refined procedures to study Pavlovian influences on goal-directed behavior in mice and studied the effects of CS-US relations in Pavlovian-instrumental interactions. Independent groups of mice underwent Pavlovian training to associate either a 10-sec or 2-min auditory stimulus ( CS) with reward. We next assessed the ability of the response-contingent CS presentations to reinforce novel instrumental responding (conditioned reinforcement; CRf) or the ability of noncontingent CS presentations to increase ongoing instrumental responding (Pavlovian-instrumental transfer; PIT). Whereas 10-sec training conditions produced strong CRf (and no PIT), 2-min training conditions produced robust PIT (but no CRf).
