The hierarchical relationship between several visual and auditory discriminations and three verbal operants among
Abstract:
This study examined the relationship between performance on the Assessment of Basic Learning Abilities test (ABLA), two auditory matching tasks, and a test of echoics, tacts, and mands with persons with developmental disabilities. It was found that discrimination skill (visual, auditory-visual, and auditory-auditory discriminations) was a better predictor of performance on verbal operant assessments than level of functioning based on diagnosis. The results showed high test-retest reliability for the test of verbal operants and no hierarchical relationship was found among the three verbal operants. The results suggest that the ABLA Level 6 might be a possible bridging task for teaching echoics, tacts, and mands. Further research is needed to ascertain the relation between the auditory matching tasks and the verbal operants.
