Memory appears to accumulate as an increased number of training blocks are added. Mean response magnitudes of test phase for trained groups that received one, two, three, or four blocks of training (open bars) compared with their respective single-tap matched control groups (solid bars) shows that as amount of training increases, the mean response magnitude decreases for the trained group, therefore indicating greater long-term retention. Mean response magnitudes are expressed as percent control group response. (*) P<0.05.
