Previous studies have reported acoustic factors to be of little importance in the release from proactive-inhibition methodology. 96 Ss were run to investigate whether words are encoded acoustically in the release from proactive-inhibition paradigm. Half of the Ss experienced acoustically similar triads for 4 trials; the other half were shifted to an acoustically different triad on the fourth trial. Proactive inhibition increased for both groups during the first 3 trials. Release from proactive inhibition was obtained on the fourth trial for the shifted group. The changes in proactive inhibition were interpreted as encoding along the acoustic dimension.
