A 10-year-old autistic child was trained to imitate verbal prompts describing the child's motor responses. When intervention was introduced in the form of a gradual delay in the presentation of the verbal prompts, the child's spontaneous speech on trained items increased. Generalization and maintenance were analyzed. (Author/JDD)

The sleep-wake cycles of 4 developmentally delayed individuals (ages 3-19) with severe sleep disturbances were regulated using a faded bedtime procedure with response cost. Following treatment, all four increased their amounts of nighttime sleep; two decreased their excessive daytime sleep; and three decreased their night wakings. (Author/JDD)

Three mentally handicapped students (aged 13, 36, and 40) with maladaptive speech received training to answer questions with verbal labels. The results of their cues-pause-point training showed that the students replaced their maladaptive speech with correct labels (answers) to questions in the training setting and three generalization settings.…

This essay discusses the significance functional analysis has had for applied behavior analysis of aberrant behavior. The methodology has lessened the field's reliance on default technologies and promoted analysis of environment-behavior interactions maintaining target responses as the basis for selecting treatments. It has also contributed to the…

The study reduced the disruptive behaviors of students in 2 elementary physical education classes, including an alternative education class containing 14 fourth and fifth grade boys with severe behavior problems. A modified time-out procedure was used to reduce frequency of disruptive behaviors by 95 percent. (Author/DB)

This study found consistently reduced levels of problem behaviors with three students (ages 5-11) with severe autism and/or mental retardation when the students were given opportunities, during a session, to make choices among instructional tasks and reinforcers. Choice-making opportunities did not impact the rate of correct responding on…

A behavioral consultation approach was effectively used to reduce problem behaviors in 2 field studies with 3 students (ages 10-14) having severe or profound mental retardation and their teachers. Intervention involved extinction of inappropriate behaviors, reinforcement of appropriate play behaviors, and teaching verbal skills functionally…

Three severely retarded persons displaying self-injury, stereotypy, or aggression were trained to emit a communicative response that solicited reinforcement. Results showed that consequence procedures were required in addition to reinforcement. Treating aberrant behavior through use of functional analysis to identify maintaining contingencies and…

Two adult males with severe motor and speech deficits resulting from cerebral palsy were trained to use an augmentative communication system (Touch Talker) independently. Results demonstrated that training on operation of the device was insufficient to ensure improvement in conversation performance and that it was important to incorporate direct…

Two male adults with cocaine dependence received a behavioral intervention comprised of contingency management and the community reinforcement approach. Reinforcement was delivered contingent on submitting cocaine-free (and subsequently marijuana-free) urine specimens. The intervention was efficacious in achieving abstinence from cocaine and…

Three mentally retarded students (ages 9-12) who exhibited challenging behaviors to escape from academic demands and to receive social attention were taught alternative assistance-seeking and attention-getting phrases. Data indicated that the intervention reduced challenging behavior. The results transferred across settings, and were maintained 18…

Parents of four nonverbal and four echolalic autistic children, aged five-nine, were trained to increase their children's speech by using the Natural Language Paradigm. Following training, parents increased the frequency with which they required their children to speak, and children increased the frequency of their verbalizations in three…

Two severely handicapped children (ages 5-6) exhibiting self-injurious behavior were treated with negative reinforcement (brief escape from grooming activities) contingent upon a behavior that was incompatible with self-injury (pressing a microswitch that activated a "stop" message). Treatment led to decreased self-injury, which was maintained at…

Two studies of three youths (ages 12-14) with severe mental retardation, who used aggression and self-injury to avoid difficult instructional situations, found that simple commands interspersed among more challenging instructional trials were effective at increasing the learners' responsiveness to instructions and decreasing levels of problem…
