This study compared the effects of unequal and equal reinforcer duration during a functional analysis of aberrant behavior in an 11-year old with moderate mental retardation. Results showed that reinforcer duration affects the rate of aberrant behavior and may potentially alter functional analysis interpretation. (DB)

Three experiments were conducted with two participants with mental retardation that displayed property destruction and stereotypy. The experiments assessed the function of the responses, determined their relationship, and developed a treatment to reduce property destruction. Response blocking reduced property destruction (and attempts), prevented…

Assessed main and collateral effects of the assessment and treatment of attention-maintained self-injury, with regard to four categories of behavior: self-injury, a novel mand, pre-existing prosocial responses, and other aberrant responses. Results suggest that self-injury, prosocial responses, and other abberant behaviors are within the same…

Chronotherapy was used to treat severe sleep problems in a girl with mental retardation. Chronotherapy involved systematically delaying the child's bedtime each night while maintaining a regular schedule during waking hours until an age-appropriate bedtime was achieved (in 11 days). Immediate improvements in the child's sleep patterns were…

Discussion of the functional relationship between self-injurious behavior (SIB) and self-restraint in people with severe disabilities considers SIB and self-restraint as members of the same functional response class, SIB and self-restraint as functionally independent responses, access to self-restraint as positive reinforcement of SIB, termination…
