| Abstract: | Enhancement of sensory, cutaneous stimulation may be one reason for self-injurious behavior among persons with mental retardation. For self-injury involving head or face, a contingently applied helmet prevents access to the sensitized skin area. Such a restraint procedure, with visual occlusion superimposed on the helmet, was tested with two women who are profoundly retarded. Helmet and transparent shield reduced target responses by both women to approximately 7% of baseline rates. When the helmet's face shield was made opaque, a small, further response reduction was obtained. Stable, low rates were maintained over a 6-month maintenance period. |
