Figure 7. Rats that slowed down reaction times the most reached a higher instantaneous reward rate sooner and collected more reward.

(a) Schematic showing segregation of top 25% of subjects ($n=4$) with the largest initial ΔRTs for the new visible stimuli and the bottom 25% of subjects ($n=4$) with the smallest initial ΔRTs. Initial ΔRTs were calculated as an average of the first two sessions for all subjects. (b) Mean $iRR$ for subjects with largest and smallest mean changes in reaction time across task engagement time. (c) Mean cumulative reward over task engagement time for subjects as in b.
