The Audio-Visual Combination (AVC) scale (Kerr, Meyerson, & Flora, 1977) was developed to assess basic discrimination skills in the developmentally disabled population. Acquisition of such skills has been demonstrated to follow a progressive pattern. The existing AVC test assesses discrimination skills in the following hierarchy: Imitation, Position, Visual, Match-To-Sample, Auditory, and Auditory- Visual Combination. This investigation attempted to discover transitional skills between the Match-To-Sample and the Auditory levels. Twenty-four developmentally disabled adults were tested using the original AVC tool with the addition of four new discrimination tasks that were added to the existing scale to ascertain a finer gradation of skills. Results showed that the new discrimination skills are not, in fact, intermediary, except possibly for one form of a visual nonidentity match-to-sample task.
