Consummatory performance measure in terms of cumulative contact with the sipper tube (goal-tracking time, in seconds) in two groups of rats exposed to a 32-to-4% sucrose downshift (32-4) or to unshifted 4% sucrose (4-4). The cSNC effect is illustrated by the difference in consummatory behavior during Trials 11-15, when animals in both groups receive access to 4% sucrose, but differ in terms of prior reward history.
