Stephen D. Oller, PhD, is an associate professor in the Communication Sciences and Disorders Program (in the Department of Biological and Health Sciences) at Texas A&M University-Kingsville. He is currently working with Driscoll Children's Hospital in Corpus Christi, Texas, to develop an assessment protocol to be used with clients receiving speech and/or occupational therapy that incorporates sensory integration practices. A portion of this protocol includes the Milestones Scale, which is intended to help therapists ascertain a lower boundary of the zone of proximal development when selecting therapy targets for their clients.
