Maintenance of self-administration, extinction, and reinstatement of alcohol- and food-seeking behavior. Active lever presses that previously resulted in alcohol or food delivery were significantly decreased during extinction training as compared to when alcohol or food was available (+, p <0.001). During reinstatement tests, response-contingent presentation of the light-tone stimulus that was previously paired with either alcohol or food significantly increased active but not inactive lever presses as compared to those observed during extinction (*, p<.01). Data are presented as mean ± SEM.
