The effects of superimposing operant reward and omission contingencies on 2 Pavlovian conditioned responses evoked by a visual conditioned stimulus paired with food were examined in rats with lesions of the amygdala central nucleus (CN). In sham-lesioned rats, the frequency of an orienting response, rearing, was increased by reward contingencies and decreased by omission contingencies, compared with yoked Pavlovian controls. In contrast, in CN-lesioned rats, rearing was not affected by either operant contingency and occurred at lower levels with Pavlovian procedures alone than in sham-lesioned rats. Nevertheless, CN-lesioned and sham-lesioned rats showed similar increases in the frequency of conditioned food-cup behavior with reward contingencies, similar decreases with omission contingencies, and similar levels of that response with Pavlovian procedures.
