Analysis of the US-Preexposure Effect in Flavor Acceptance Conditioning
Gil, Marta; Symonds, Michelle; Hall, Geoffrey; de Brugada, Isabel
Learning and Motivation, v42 n4 p273-281 Nov 2011
In three experiments, rats received exposure to a sucrose solution followed by conditioning with a neutral flavor as the conditioned stimulus (CS) and sucrose as the unconditioned stimulus (US). In Experiments 1 and 2, some rats were given both the preexposure and the conditioning phases in a highly familiar context (the homecage), whereas other animals received both phases in a novel and distinctive context. In both cases the magnitude of the conditioning effect was reduced by preexposure to the US. Experiment 3 directly assessed the possible role of contextual cues by changing the context between the exposure phase and the conditioning phase but found no loss of the US-preexposure effect in these conditions. These results lend no support to the blocking-by-context account of the US-preexposure effect; alternative interpretations are considered. (Contains 3 figures and 2 tables.)
