Extinction of the initial within-compound association established in a blocked preexposure to two compound flavours. Psicológica, 39(1), 25–40. https://doi.org/10.2478/psicolj-2018-0002 https://hdl.handle.net/10630/33328 10.2478/psicolj-2018-0002 Extinction of the A↔X association after blocked preexposure to AX-BX was studied in two experiments. In Experiment 1, two groups of rats received long (14 trials) or short (4 trials) blocked preexposure to AX-BX and subsequent conditioning of X. The results showed that the AX association was equally preserved after long and short preexposure. Experiment 2 studied the effect of blocked preexposure to 0, 1 or 2 ruptures of the AX association on extinction. In this experiment a "rupture" is produced when, in subsequent blocks, one element of the original compound is presented in compound with a different element. A significant extinction was observed only when the AX association was broken twice eng http://creativecommons.org/licenses/by-nc-nd/4.0/ open access Attribution-NonCommercial-NoDerivatives 4.0 Internacional Inhibición Extinction of the initial within-compound association established in a blocked preexposure to two compound flavours journal article
