  • Scores are the number of trials (TTC) and errors (ETC) preceding the learning criterion in DNML and correction training and performance scores (percentage) obtained during the criterion run in DNML and correction training. The percentage of correct responses over 100 trials for each extended delays of the DNML and DNMS is shown. The average is the mean percentage of correct responses across the four delays.
