Effects of training in monitoring accuracy on processing speed in mental retardation.

Monitoring accuracy during choice RT allows subjects to maintain fast, safe RT bands and avoid overly fast, unsafe RT bands. 5 retarded adults received trial-by-trial feedback on accuracy over a number of sessions to train monitoring of accuracy and to improve RT performance. Training was introduced according to a multiple-baseline-across-subjects (with reversal) design. Training had no significant effect on subsequent RT performance, suggesting that inefficient monitoring of accuracy may be a structural characteristic of mental retardation.
