Covert self-injurious behavior (i.e., behavior that occurs in the absence of other people) can be difficult to treat. Traditional treatments typically have involved sophisticated methods of observation and often have employed positive punishment procedures. The current study evaluated the effectiveness of a variable momentary differential…

Some students with intellectual disabilities require explicit instruction of language skills, including preposition use; however, little is known about effective ways to teach preposition use to this population. This study examined direct instruction (DI) to teach students to use and respond to prepositions. Results indicated that DI was an…

The study analyzed the effects of self-recording and behavioral skills training on guarding responses of 3 staff members while they assisted 3 students with multiple disabilities to ambulate. The intervention increased the percentage of correct posture and guarding responses and the distance that students ambulated. These effects generalized when…

The current study examined the rate of expulsions and mouth cleans across 3 presentation methods (upright spoon, flipped spoon, Nuk brush) for a 3-year-old girl with a feeding disorder. The participant expelled all bites presented on an upright spoon. Results showed reduced rates of expulsions and increased mouth cleans during the flipped spoon…

Although delusional statements in people with intellectual disabilities and traumatic brain injury can be treated using behavioral interventions, none have demonstrated long-term treatment effects. In the current study, a functional analysis demonstrated that delusional statements were maintained by attention. Differential reinforcement of…

A multielement design was used to compare the effects of three treatments on the happiness of 3 individuals with profound multiple disabilities. The conditions were typical programming using materials selected by staff, presentation of preferred materials plus social interaction, and social interaction alone with no materials present. Both the…

Results showed that the graduated prompting procedure was effective in training reach-grasp responding in all three children; for one child, effects were durable over repeated treatment applications, but not maintained during withdrawals; for another child, the procedure was effective in teaching reach-grasp responding in all three positions.…

This study assessed the validity of idiosyncratic choice-making behaviors of three children with multiple disabilities. Children were given either their "choice" of food or drink or were given the opposite. Direct observations of children's acceptance or refusal revealed the children consistently indicated choices during both conditions.…

Five students (13-18 years old) classified as profoundly/multiply handicapped were trained to use microswitches to indicate reinforcer preferences. When the microswitches activated the devices during training, a substantial increase in the duration of motoric responding occurred for all students. In addition, some students performed differentially…

Three experiments were conducted involving five people with profound multiple disabilities, to determine whether variations in alertness affected subsequent responsiveness to training programs. Findings suggest that existing levels of alertness do not indicate how individuals will respond during training and that alertness actually can be…

Behavior analysis has been at the forefront in establishing effective treatments for children and adults with chronic tic disorders. As is customary in behavior analysis, the efficacy of these treatments has been established using direct-observation assessment methods. Although behavior-analytic treatments have enjoyed acceptance and integration…

This study examined the outcomes of a competing activities intervention to decrease skin picking exhibited by a 9-year-old student with comorbid diagnoses. Results of an ABCBAB design revealed that the use of student-selected manipulatives resulted in reduced skin picking. (Contains 1 figure.)

Four multiply handicapped students (aged 5-11) received skill instruction under four experimental conditions, involving differing teacher wait-times and intertrial interval durations. Student performance was superior under the long wait-time conditions irrespective of the length of the intertrial interval. (Author/JDD)

Four experiments involving 18 individuals (ages 14-55) with profound multiple handicaps found that 12 stimuli used in a preference assessment represented a comprehensive stimulus set for identifying preferences, though the utility of the set could sometimes be enhanced by caregiver opinion. Results also indicated that preferences identified were…

Measurement training had little general effect on either the behavior of two teachers or of their multihandicapped deaf students. However, after programing training, teachers increased their program writing and correct use of behavior modification procedures and generalized this training across pupils and target behaviors.
