Spontaneous Recovery (SR) refers to the reemergence of an extinguished conditioned response after a resting period. SR occurs in a variety of Pavlovian situations, but remains to be shown in the consummatory successive negative contrast (cSNC) situation. Results failed to show SR at 96-h and 336-h resting periods and accordingly failed to show greater SR at 336-h compared to 96-h. However, a median-split procedure to group downshifted subjects as high spontaneous recovery (H) or low spontaneous recovery (L) in the SR trial, revealed: (1) H96 and H336, but not H24, showed significant consummatory suppression compared to L and unshifted controls; (2) L96 and L336 showed significantly faster recovery from initial contrast than their respective H counterparts; and (3) A significant positive correlation between degree of SR on trial 19 and recovery from contrast. Results indicate any demonstration of SR in cSNC must take into account individual differences in consummatory behavior.
