Figure 4. Devaluation by Lithium Chloride

(A) Revisits to locations that recently provided a distinctive food type occurred at a higher rate after long retention intervals than after short retention intervals.

(B) Revisits to the location with a devalued (chocolate), but not a nondevalued (banana), distinctive food type were selectively reduced relative to baseline performance (before LiCl). The dependent measure was the probability of a revisit in the first four arm visits during a test phase. Error bars represent SEM.
