DISSOCIATION OF CONDITIONED APPETITIVE AND CONSUMMATORY SEXUAL-BEHAVIOR - SATIATION AND EXTINCTION TESTS

Sexual responses were conditioned in male Japanese quail using the opp ortunity to copulate with a female as the unconditioned stimulus (US). The conditioned stimulus (CS) was a 3-D object made of a taxidermical ly prepared female quail head mounted on a terry-cloth body. Both appe titive conditioned responses (approach and proximity to the GS) and co nsummatory conditioned responses (mount and cloacal contact directed t oward the CS) developed when 2-min presentations of the CS were follow ed immediately by the US, but not when the CS and US were separated by trace intervals of 10 or 20 min (Experiment I). Postconditioning sexu al satiation suppressed conditioned cloacal contact responses more tha n conditioned approach to the GS (Experiment 2), and ''acute'' extinct ion suppressed both conditioned mounting and conditioned cloacal conta ct responses more than conditioned approach to the CS (Experiment 3). These results demonstrate a functional dissociation between conditione d appetitive and consummatory responses and imply that the motivationa l and/or associative mechanisms underlying the two types of behavior a re distinct.
