✦ Synopsis
In the present study, a naturalistic functional analysis procedure was used to assess the effect of environmental stimulation on the stereotypic behavior (body rocking) of an adult whose stereotypy appeared to be induced by an acquired brain injury. Environmental stimulation, operationalized in terms of both physical and social characteristics, resulted in only minimal changes in the Occurrence of body rocking. Body rocking Occurred in excess of 50% of the observations in all environmental stimulation conditions and in a naturally occurring baseline condition. To our knowledge, this is the first published report of a functional analysis of stereotypy associated with acquired brain injury.
Stereotyped Movement Disorder (SMD) is especially prevalent among individuals with severe and profound mental retardation (Baumeister & Forehand, 1973), and may be one of the more prevalent forms of behavior disorder in this population (Barton & Repp, 1981 ; Berkson, 1967). Indeed, there is an inverse correlation between level of functioning and prevalence of stereotypy (Jacobson, 1982), underscoring the importance of developmental brain injury as a contributing factor. Stereotypy may represent a decreased ability to respond adaptively to changing environments
