The extended comparator hypothesis account of responding to the target cue (X) after preexposure to X in the presence of a conditioned inhibitor (B) followed by X-US pairings. Arrows represent the associations between stimuli. The strengths of the directly and indirectly associated outcome representations are compared to determine the strength of responding to the target cue. Ovals depict stimulus representations; rectangles depict physical events; diamonds represent the comparator process. The dotted US representations indicate that B does not have a direct association with the US. Heavy lines indicate strong associations. A is the conditioned excitor used during inhibitory training of B.
