The earliest stages of functional communication training (FCT) involve providing immediate and continuous reinforcement for a communicative response (FCR) that is functionally equivalent to the targeted problem behavior. However, maintaining immediate reinforcement is not practical, and the introduction of delays is associated with increased…

Background: Fear of medical procedures in general and needles in particular can be a difficult clinical challenge to providing effective health care for individuals with intellectual and developmental disabilities. Methods: A changing criterion design was used to examine graduated exposure treatment for blood-injury-injection phobia in an adult…

Few studies have examined the relationship between heart rate and self-injurious behavior (SIB) shown by individuals with IDD (intellectual and developmental disabilities). In this single-case study, we simultaneously monitored heart rate and activity levels during a functional analysis of severe skin picking behavior exhibited by a young man with…

Brief experimental analysis (BEA) is a useful tool for quickly evaluating intervention strategies for individuals with academic deficits and minor behavior problems. However, there is a lack of research investigating BEA for intervention strategies with individuals who emit severe problem behavior to avoid academic demands. For the current study,…

Aversion to eye contact is a common behavior of individuals diagnosed with Fragile X syndrome (FXS); however, no studies to date have attempted to increase eye-contact duration in these individuals. In this study, we employed a percentile reinforcement schedule with and without overcorrection to shape eye-contact duration of 6 boys with FXS.…

The field of applied behavior analysis has utilized the ability to capture and contrive establishing operations in treating aberrant behavior in individuals with developmental disabilities. However, research on the use of establishing operations in the teaching of appropriate behavior is not as systematic. This study examined the effects of…

The aim of the present study was to demonstrate the efficacy of combining two operant learning procedures--shaping and fading--for treating selective mutism. The participant was a 12-year-old boy with mental retardation presenting a severe long-term selective mutism. The treatment was aimed at increasing the loudness of his vocalizations in an…

Available from: Sage Publications, Inc., 275 South Beverly Drive, Beverly Hills, California 90212. The effect of a differential reinforcement procedure alone was compared with the use of verbal prompts plus differential reinforcement in reducing deviant social behavior of an institutionalized retarded male (28 years old).

The study investigated the manner in which locus of control (the degree to which an individual conceptualizes a relationship between his own behavior and the outcomes of this behavior) interacted with selected task and reinforcer variables in the performance of educable mentally handicapped boys. One hundred ninety-two adolescent males performed…

WORKING FROM A POPULATION OF SEVERELY AND PROFOUNDLY RETARDED RESIDENTIAL SCHOOL PATIENTS, AN ATTEMPT WAS MADE TO DEVISE AN EXPERIMENTAL PROGRAM FOR TRAINING SUBJECTS ON SELECTED WORKSHOP TASKS. TASK ANALYSIS WAS EMPLOYED TO DESCRIBE THE RESPECTIVE VOCATIONAL ENVIRONMENTS AND TO SPECIFY BEHAVIORAL REQUIREMENTS. TRAINING PROGRAMS BASED UPON THE…

We conducted three studies which examined the performance vs. skill acquisition model of social skills deficits. In Study 1, baseline social behaviors for a random sample of 12 boys with comorbid emotional and behavioral disorders (EBD), learning disabilities (LD), language delays, and Attention Deficit Hyperactivity Disorder (ADHD) revealed that…

The effects of social and monetary reinforcements on mentally handicapped in a sheltered workshop setting were examined. Performance rates were found to be facilitated by visual display and verbal reinforcement more than by token reinforcement techniques. (CD)

Two groups of 20 mentally retarded boys (10-to 14-years old) were presented with an adapted version of the Royal Canadian Air Force Physical Fitness Training Program. (GW)

Reports on two treatment studies of special education students markedly helpless with regard to arithmetic: one comparing attribution retraining treatment to control treatment matched to it in schedule of successes and failures; the other comparing effects of three success-failure schedules on attributions and persistence.
