Relative Effectiveness of Motor and Vocal Correction during Discrimination Learning

Abstract

An orthogonal design was used to evaluate the relative effectiveness of motor and vocal correction for adult Ss learning a 15-pair discrimination task. Both affected performance, but vocal correction had a considerably stronger effect and combined motor and vocal correction was not more effective than vocal correction alone. It was noted that the variability of performance, as well as the mean number of errors, was reduced by correction.
