We describe a training program to teach applied behavior analysis (ABA) knowledge competencies to paraprofessional staff (N = 47) at a habilitation services agency for adults with developmental disabilities. Before and following training, staff completed assessment of knowledge tests for three content areas: basic learning principles,…

In this case study, a six-year-old, multihandicapped child was treated for self-injurious arm-biting using two response contingent deceleration procedures and two forms of sensory extinction. Only the sensory extinction procedure with protective cuffs reduced arm-biting to manageable levels. (Author/DB)

Therapeutic intervention to treat chronic food refusal in two children with multiple developmental disabilities consisted of elimination of feeding "demands" that provoked child agitation, incorporation of sensory stimulation as contingent reinforcement, and gradual introduction of the requirements for oral consumption. Consistent oral…

We evaluated contingent and noncontingent practice of an alternative behavior (appropriate play) as intervention for stereotypy that occurred with two play objects in a 5-year old boy with autism. Contingent practice was implemented as a consequence for stereotypy, and the rate of noncontingent practice was matched (yoked) to that schedule. On…

A 13-year-old deaf-blind boy who exhibited disruptive problem behaviors during mobility training sessions was successfully treated in a program that incorporated contingent reinforcement for reduced rates of responding. A 1-year follow-up assessment revealed continued behavioral improvement. (Author/JDD)
