Ikaskuntza pertzeptiboa: aldibereko aurre-esposizioaren efektua

Abstract

Two experiments determined the effect of concurrent pre-exposure to two concentrations of one flavor on generalization of taste aversion in rats. Pre-exposure was continuous and long (24 h daily for 28 days) in Experiment 1 and discrete and short (30 minute morning and afternoon sessions for 4 days) in Experiment 2. In both experiments concurrent exposure failed to reduce generalization more that an equivalent pre-exposure in separate blocks. In experiemnt 2, there was a differential response between the conditioned and test stimuli after concurrent pre-exposure. Results are discussed in relation to the role of stimulus comparison processes in perceptual learning.
