In Experiment 1, rats provided with brief daily access to 4% sucrose which preceded brief
access to 32% sucrose (4-32) suppressed licking the 4% solution relative to 4-4 controls …

An important tenet of optimal foraging theory is that foragers compare prey densities in
alternative patches to determine an optimal distribution of foraging behavior over time. A …

Contrast effects were obtained in rats in the consumption of saccharin solutions in three
different paradigms. Degree of negative contrast varied as a function of concentration …

Intake of an initial substance (eg, 0.15% saccharin) is suppressed when the presentation of
this substance precedes the availability of a preferred solution (eg, 32% sucrose) in brief …

The Wistar Kyoto (WKY) rat has been proposed as a model of depression-like symptoms.
However, anhedonia—a reduction in the response to normatively rewarding events—as a …

In the words of the late Charles Flaherty, reward comparison is commonplace. Rats and
humans, it appears, compare all rewards and this capacity probably contributes to our ability …
