GOAL-DIRECTED AND HABITUAL BEHAVIOR CHAINS IN RATS AND HUMANS
ERIC THRAILKILL, CATHERINE THORPE, MARK BOUTON (UNIVERSITY OF VERMONT)
Behavior chains are sequences of linked responses required to earn a reinforcer. Here we show in rats that R1 is sensitive to the value of R2 (a goal-directed action) and becomes insensitive (a habit) after extended training. We then show analogous findings with a novel computer task in human participants. The results implicate common associative mechanisms in instrumental learning across rats and humans and inform our understanding of how habits are made and broken.

2:20pm - 2:35pm
EXTINCTION, BUT NOT SPONTANEOUS RECOVERY, OF CONDITIONED FLAVOR PREFERENCES
ANDREW DELAMATER (BROOKLYN COLLEGE - CITY UNIVERSITY OF NEW YORK), JASMINE HUANG (MIDWOOD HIGH SCHOOL)
A conditioned flavor preference develops when a neutral flavor is paired with a nutrient. We previously demonstrated that this learned preference is highly sensitive to flavor nonreinforcement either prior to (latent inhibition), during (partial reinforcement), or following (extinction) flavor-nutrient pairings. Here we assess the role of the number of flavor-nutrient pairings prior to extinction, and the possibility of spontaneous recovery. Extinction in this paradigm is robust and appears not to spontaneously recover.

2:40pm - 2:55pm
RETROACTIVE INTERFERENCE: COUNTERCONDITIONING AND EXTINCTION WITH AND WITHOUT BIOLOGICALLY SIGNIFICANT OUTCOMES
YAROSLAV MOSHCHENKO, ALAINA BERRUTI, JACOB BLATTSTEIN (STATE UNIVERSITY OF NEW YORK AT BINGHAMTON), JÉRÉMIE JOZEFOWIEZ (UNIVERSITÉ DE LILLE), RALPH MILLER (STATE UNIVERSITY OF NEW YORK AT BINGHAMTON)
Maladaptive Pavlovian conditioning (CS-Outcome1) is reduced through extinction (CS-alone) or counterconditioning (CS-Outcome2). Towards better understanding the underlying bases of these phenomena, particularly the reversal of evaluative conditioning during counterconditioning, extinction and counterconditioning were compared using a contingency preparation. The two phenomena differed appreciably in sensitivity to renewal as a function of whether the outcome(s) were biologically significant. Centrally, neutral outcomes in counterconditioning allow assessment of pure associative interference devoid of evaluative conditioning. LOCATION: END:VEVENT END:VCALENDAR
