| Abstract: | Three conditioned lick suppression experiments with rats were performed to assess the influence, following compound training
of two stimuli (A and X) with the same outcome (AX-O trials), of extending training of the blocking association (i.e., A-O)
on responding to the target stimulus (X) at test. In Experiment 1, backward blocking was attenuated when the blocking association
was extensively trained. Experiment 2 showed that forward blocking was also attenuated by extensive further training of the
blocking association following the AX-O trials. Experiment 3 contrasted candidate explanations of the results of Experiments
1 and 2 and demonstrated that these results are consistent with the framework of the extended comparator hypothesis (Denniston,
Savastano, & Miller, 2001). |
