Inhibitory training provided by Barnet and Miller (1996). CSs A, B, C, X, and Y, were 5-s audiovisual stimuli; ‘+’ denotes a footshock; ‘−’ denotes nonreinforcement. Stippled bars indicate presentation of an excitatory CS; filled bars depict presentation of the US; striped bars depict presentation of the conditioned inhibitor; and open bars depict expectation of the omission of the US. At test, animals received presentations of C, XC, or YC. Stimuli in parentheses are hypothetical neural activations of the training excitors and their associated USs. Dashed ovals represent simultaneous activation of the US by the transfer excitor and the omission of the US by the conditioned inhibitor. Upper case CR’s denote the observation at test of strong conditioned behavior and lower case cr’s denote weak conditioned behavior.
