An inhibitory within-compound association attenuates overshadowing. [PDF]
Journal of Experimental Psychology: Animal Behavior Processes, 2008 According to the comparator hypothesis (Miller & Matzel, 1988), cue competition depends on the association between a target stimulus (X) and a competing cue (e.g., an overshadowing cue [A]). Thus, it was expected that overshadowing would be reduced by establishing an inhibitory-like relationship between X and A before compound conditioning.
