Conditioned barpress suppression by rats was used to explore the associative status of an initially neutral stimulus that was reinforced in simultaneous compound with two independently pretrained conditioned excitors. In contrast to the Rescorla-Wagner model, which predicts that the target stimulus (X) will be inhibitory following such A+ /B+ /ABX + training, the present study found no evidence that X acquired inhibitory associative strength. Rather, the pretrained stimuli merely served to block conditioned excitatory responding to the target stimulus.
