A PARAMETRIC ANALYSIS OF ERRORS OF COMMISSION DURING DISCRETE‐TRIAL TRAINING

Abstract

We investigated the effects of systematic changes in levels of treatment integrity by altering errors of commission during error‐correction procedures as part of discrete‐trial training. We taught 3 students with autism receptive nonsense shapes under 3 treatment integrity conditions (0%, 50%, or 100% errors of commission). Participants exhibited higher levels of performance during perfect implementation (0% errors). For 2 of the 3 participants, performance was low and showed no differentiation in the remaining conditions. Findings suggest that 50% commission errors may be as detrimental as 100% commission errors on teaching outcomes.
