Healthy aging in rats is associated with a decline in the ability to inhibit maladaptive responses, but not in measures of self-control by delayed gratification.

We did observe a trend toward significance with our movement time measures as a function of session [ F (14,298) = 1.692, p = 0.0564], but no interactions with session were significant ( p ’s > 0.05), suggesting that across treatment groups animals tended to speed up responding slightly with repeated testing.
