Extinction, Spontaneous Recovery and Renewal of Flavor Preferences Based on Taste-Taste Learning
Diaz, Estrella; De la Casa, L. G.
Learning and Motivation, v42 n1 p64-75 Feb 2011
This paper presents evidence of extinction, spontaneous recovery and renewal in a conditioned preferences paradigm based on taste-taste associations. More specifically, in three experiments rats exposed to a simultaneous compound of citric acid-saccharin solution showed a preference for the citric solution when the preference was measured with a two-bottle test (citric vs. water). Experiment 1 revealed that conditioned preferences were extinguished by repeated presentations of the citric acid solution without the saccharin. In Experiment 2, an additional test trial was introduced 21 days after the extinction treatment. Delayed testing resulted in the recovery of the extinguished preference for the citric, reflecting a spontaneous recovery effect. Experiment 3 revealed a preference renewal effect that was obtained when the extinction was conducted in a context different from that of the remaining experimental stages. The implications of these results are analyzed with attention paid to the mechanisms underlying learning of flavor preferences. (Contains 6 figures and 1 table.)
