Compound Cue

Repeated experience with artificial sweeteners increases food consumption and body weight gain in rats. Saccharin consumption may reduce the conditioned satiety response to sweet-tasting food. Rats were trained to press a lever to obtain sucrose for five days. A compound cue (tone + light) was presented with every sucrose delivery. On the following day, each lever press produced only the compound cue (cue-reactivity test). Subjects were then provided with yogurt for three weeks in their home cages. The rats were divided into two groups. Rats in the saccharin group received yogurt sweetened with saccharin on some days and unsweetened yogurt on others. For the plain group, only unsweetened plain yogurt was provided. Subsequently, the cue-reactivity test was conducted again. On the following day, the rats underwent a consumption test in which each lever press was reinforced with sucrose. Chow consumption and body weight gain were larger in the saccharin group than in the plain group. Lever responses increased from the first to the second cue-reactivity tests (incubation of craving) in both groups. During the consumption test, lever responses were higher in the saccharin group than in the plain group, suggesting that the conditioned satiety response was impaired in the saccharin group.

Reliable Preference

Two groups of 12 8-wk.-old kittens were tested for the reinforcing effect of illumination change resulting from displacement of a spherical plastic manipulandum. For one group responding turned on a dim light in the darkened test box, and for the other group responding turned the light off. Both groups were given 3 familiarization sessions followed by 8 test sessions in which one of two identical manipulanda affected illumination. The onset group developed a reliable preference for the light change manipulandum, and the light offset group did not.
