We assessed the applicability of two previously developed reinforcer assessment procedures to children with developmental disabilities and visual impairments. Greater differentiation between stimuli was observed with a choice procedure than with a preference procedure. Measurement of compliance and rate of responding in adaptive skill training confirmed that the choice procedure accurately identified reinforcing stimuli. The preference procedure produced false positive predictions of reinforcer efficacy.
