The relationship between preferred objects associated with stereotypy, stereotypic behavior, and accuracy of responding during a counting task by a child with autism was analyzed. Teaching with high-preference objects occasioned more stereotypic behavior and less accurate counting than teaching with medium- and low-preference objects. (Author/DB)

The study evaluated a reinforcement theory of stereotyped behavior with six autistic students (ages 9-16). Three students evidenced decreases in stereotypy and increases in responding in the presence of usual reinforcers, while the other three students required external suppression of stereotypy before increases in responding were shown.…

This study examined effects of cue control and behavioral relaxation training (BRT) with five subjects having severe mental retardation. BRT produced reductions in rated anxiety and improvements in concentration for all subjects. Cue control words were effective only after they had been linked with BRT. (DB)

Evaluation of a protocol for assessing leisure choice skills of seven older adults with severe disabilities involved either presentation with pairs of objects or pictures representing choices. Five participants demonstrated skills in making choices using objects and two demonstrated making choices using pictures. (Author/DB)

Two experiments with 15 individuals having profound mental retardation found difficulties in identifying reinforcers that were actually effective in treatment of chronic training needs. Research needs in evaluating training alternatives for people with profound multiple disabilities who move very little or who respond with very long latencies are…

The study compared the effectiveness and efficiency of concurrent and isolation-intermix instruction in teaching four preschool children to read common words in their environment. Concurrent instruction resulted in students learning conditional discriminations in fewer trials and minutes of instructional time suggesting the value of teaching…

This study describes the development of the Active Treatment Client Rights checklist (ATCR), which was designed to facilitate the assessment, monitoring, and implementation of readily observable client active treatment services for adults with developmental disabilities. The ATCR was found to be highly reliable, valid, and useful in enhancing…

This study evaluated the reliability of the Child Behavior Checklist with 42 children and youth with mild mental retardation. Use of kappa coefficients and intra-class correlations at item and syndrome levels indicated that the Child Behavior Checklist may not always represent a reliable checklist for the assessment of psychopathology in this…

Incidental teaching and traditional discrete-trial procedures were used to teach two children (ages 10 and 12) with autism the expressive use of two color adjectives. Results demonstrated that traditional discrete-trial teaching was more efficient and produced faster acquisition but incidental teaching resulted in greater generalization and equal…

This study evaluated a method for assessing the behavioral function of severe self-injury in four adults with severe/profound mental retardation. Initial assessment included analyzing within-session trends and fluctuations in rates of self-injury by plotting the frequency within each minute of the session. (DB)

This article discusses clinical application of functional analysis in developmental disabilities, reviewing issues related to treatment logic and development. The article then approaches functional analysis as a research method, reviewing three areas of research: analysis of diverse response topographies, analysis of basic behavioral processes,…

This paper reviews the literature on functional assessment in the behavioral treatment of aggression in persons with mental retardation or developmental delays. Increased use of functional assessment and skill training is noted but no concomitant decrease in the use of intrusive procedures. (Author/DB)

This study examined the social validation of using microswitches versus interaction/stimulation conditions with persons with multiple disabilities. Teacher-assistant trainees and rehabilitation staff (n=72) were shown videotapes comparing the two methods and then scored both approaches. The microswitch condition was viewed as generally more…

Time-based lag sequential analyses were conducted on 23 topographies of challenging behavior shown by 5 young people with severe mental retardation across 2 settings. Potential behavioral functions were identified for 21 of the 23 behaviors. Response classes were identified for four participants. Cross-validation with brief experimental analyses…

The Verbal Interaction Analysis System is presented as an assessment of initial, dyadic conversations. Application of the VIAS to two case studies featuring mildly to moderately intellectually disabled adults shows how the VIAS provides an index of competence and assists in the development of specific treatment strategies.
