We conducted a systematic analysis of studies that involved the treatment of rumination and operant vomiting in individuals with developmental disabilities. A total of 21 studies involving a combined 32 participants were identified and analyzed in terms of (a) participant characteristics, (b) dependent variables, (c) intervention procedures, (d)…

We examined the effects of presession levels of attention (no attention vs. continuous attention) during subsequent alone and attention-extinction conditions for an individual with severe disabilities and problem behavior. A prior functional analysis indicated that attention was a primary maintaining variable for problem behavior. Experimental…

Sensitivity theory attempts to account for the variability often observed in challenging behavior by recourse to the "aberrant motivation" of people with intellectual and developmental disabilities. In this article, we suggest that a functional analysis based on environmental (challenging environments) and biological (challenging needs) motivating…
