An examination of changes in behavioral control when stimuli with different associative histories are conditioned in compound.

This series of experiments used rats to examine changes in behavioral control when stimuli with different associative histories are conditioned in compound. The initial experiments used blocking designs. Experiment 1 provided a within-subject demonstration of blocking, and Experiment 2 used the compound test procedure to show that, when a novel stimulus, X, is conditioned in compound with an already conditioned stimulus (CS), A, these...
