Abstract

Conducted 2 experiments with 32 male Sprague-Dawley rats in each. Ss received 1st- and 2nd-order conditioning based upon a food UCS. They then received 1 of 2 manipulations designed to reduce the value of that food, satiation, or pairing of food with high-speed rotation. The effects of these manipulations were assessed during extinction tests of the CSs. Compared with controls, both manipulations reduced the activity produced by the 1st-order CS but did not affect that produced by a 2nd-order CS. Results are interpreted as consistent with those from aversive UCSs in implying the involvement of a UCS representation in 1st- but not in 2nd-order conditioning. They also suggest that a major effect of satiation is to reduce the value of the UCS. (15 ref) (PsycINFO Database Record (c) 2006 APA, all rights reserved).
