TEACHING LEISURE SKILLS TO SEVERELY HANDICAPPED ADULTS: AN AGE-APPROPRIATE DARTS GAME

This study demonstrates the acquisition and generalization of dart skills by three severely multihandicapped adults. The program took place in a community adult development center. By identifying the motor responses required to play darts, a 7-step task analysis was generated to facilitate instruction. Systematic training procedures using applied behavior analysis were implemented. A combination multiple baseline across subjects and changing criterion design was used. The results indicated that not only could this supposedly difficult skill be acquired by severely multihandicapped individuals, but that they could also generalize to other appropriate environments. Acquisition of this skill could help optimize their use of free time for leisure pursuits in a variety of settings.     

A METHOD FOR INTEGRATING AN AUTISTIC CHILD INTO A NORMAL PUBLIC-SCHOOL CLASSROOM1

This study investigated the feasibility of using behavioral techniques to integrate an autistic child into a normal public-school class with one teacher and 20 to 30 normal children. The results showed: (1) that during treatment by a therapist in the classroom, the child's appropriate verbal and social behaviors increased, and autistic mannerisms decreased; and (2) training teachers in behavioral techniques was apparently sufficient to maintain the child's appropriate school behaviors throughout kindergarten and the first grade.     

GENERALIZING ARTICULATION TRAINING WITH TRAINABLE MENTALLY RETARDED SUBJECTS1

A multiple-baseline technique was used to evaluate generalization effects during articulation training with trainable mentally retarded subjects. Four target words were selected for each subject on the basis of whether the subject could articulate the word correctly when it was modelled but could not articulate the word correctly in response to a picture of it. Five different settings were selected for generalization probing and training for each subject. In Setting 1, Experimenter 1 initiated training sequentially on all four target words for each subject. Other experimenters probed for correct articulation generalization in four other settings. Training was initiated in these four other settings sequentially only if correct responding failed to generalize to a setting. Results indicated that it was necessary to initiate training on at least three of the four selected target words in at least one additional setting with an additional trainer before correct responding generalized to untrained settings.     

An implicit technology of generalization

Traditionally, discrimination has been understood as an active process, and a technology of its procedures has been developed and practiced extensively. Generalization, by contrast, has been considered the natural result of failing to practice a discrimination technology adequately, and thus has remained a passive concept almost devoid of a technology. But, generalization is equally deserving of an active conceptualization and technology. This review summarizes the structure of the generalization literature and its implicit embryonic technology, categorizing studies designed to assess or program generalization according to nine general headings: Train and Hope; Sequential Modification; Introduce to Natural Maintaining Contingencies; Train Sufficient Exemplars; Train Loosely; Use Indiscriminable Contingencies; Program Common Stimuli; Mediate Generalization; and Train "To Generalize".     

ASSESSING AND TRAINING TEACHERS IN THE GENERAUZED USE OF BEHAVIOR MODIFICATION WITH AUTISTIC CHILDREN1

This study investigated the feasibility of developing reliable, valid criteria for measuring and training the skills necessary to teach autistic children. The behaviors of 11 teachers and 12 autistic children were recorded in a series of different teaching situations. Teacher-training was initiated at different times for different teachers. The results showed: (1) it was possible to assess empirically whether a teacher was correctly using defined behavior-modification techniques; (2) generally, for any given session, systematic improvement in the child's behavior did not occur unless the teacher working in that session had been trained to use the techniques to a high criterion; (3) all 11 teachers were rapidly trained to use these techniques; and (4) the teachers learned generalized skills effective with a variety of children and target behaviors.     

THE DEVELOPMENT OF A TREATMENT-RESEARCH PROJECT FOR DEVELOPMENTALLY DISABLED AND AUTISTIC CHILDREN

This paper describes the development and main results over the last 30 years from the treatment-research project with developmentally disabled (autistic) children in the Psychology Department at the University of California, Los Angeles (UCLA). Three important dimensions in treatment research are addressed. The first pertains to the role of serendipity or accidental discoveries, the second to the importance of pursuing inductive rather than theory-driven research, and the third to the importance of adding in a cumulative and step-wise manner to improve treatment adequacy. Data from various areas of treatment research have been used to illustrate new directions for the project. These illustrations center on early and successful attempts to isolate experimentally the environmental variables that control self-injury, failure to observe response and stimulus generalization with subsequent loss of treatment gains, and the main results of intensive and early behavioral intervention in the child's natural environment. Effective treatment for severe behavioral disorders is seen to require early intervention carried out during all or most of the child's waking hours, addressing all significant behaviors in all of the child's environments, by all significant persons, for many years.     

TEACHING CHILDREN WITH AUTISM TO USE PHOTOGRAPHIC ACTIVITY SCHEDULES: MAINTENANCE AND GENERALIZATION OF COMPLEX RESPONSE CHAINS

We used a graduated guidance procedure to teach 4 boys with autism to follow photographic activity schedules to increase on-task and on-schedule behavior. The multiple baseline across participants design included baseline, teaching, maintenance, resequencing of photographs, and generalization to novel photographs phases. The results indicated that photographic activity schedules (albums depicting after-school activities) produced sustained engagement, and skills generalized to a new sequence of photographs and to new photographs. The acquisition of schedule-following skills enabled these children with severe developmental disabilities to display lengthy response chains, independently change activities, and change activities in different group home settings in the absence of immediate supervision and prompts from others.     

PROGRAMMING GENERALIZATION OF IN-CLASS TRANSITION SKILLS: TEACHING PRESCHOOLERS WITH DEVELOPMENTAL DELAYS TO SELF-ASSESS AND RECRUIT CONTINGENT TEACHER PRAISE

We investigated a self-management intervention package that taught preschoolers with developmental delays to self-assess performance of targeted skills and to recruit teacher praise. Self-assessment alone resulted in increases in active engagement across all participants during the training sessions, but generalization to classrooms was sporadic and short-lived. When recruitment of contingent praise was added to the training package, treatment effects generalized to the participants' classrooms and teachers' rates of contingent praise increased. The implications of combining self-assessment and recruitment of contingent teacher praise are discussed.     

TREATMENT OF SOCIAL BEHAVIOR IN AUTISM THROUGH THE MODIFICATION OF PIVOTAL SOCIAL SKILLS

We examined acquisition of individual social communicative behaviors and generalization across other social behaviors in 2 children with autism. The results of a multiple baseline design showed that the children's treated social behaviors improved rapidly and that there were generalized changes in untreated social behaviors. These improvements were accompanied by increases in subjective ratings of the overall appropriateness of the children's social interactions. The results suggest the possibility of identifying pivotal response classes of social communicative behavior that may facilitate the understanding of social behavior in autism as well as improve peer interactions, social integration, and social development.     

Generalization of a tactile stimulus in horses.

Using horses, we investigated the control of operant behavior by a tactile stimulus (the training stimulus) and the generalization of behavior to six other similar test stimuli. In a stall, the experimenters mounted a response panel in the doorway. Located on this panel were a response lever and a grain dispenser. The experimenters secured a tactile-stimulus belt to the horse's back. The stimulus belt was constructed by mounting seven solenoids along a piece of burlap in a manner that allowed each to provide the delivery of a tactile stimulus, a repetitive light tapping, at different locations (spaced 10.0 cm apart) along the horse's back. Two preliminary steps were necessary before generalization testing: training a measurable response (lip pressing) and training on several reinforcement schedules in the presence of a training stimulus (tapping by one of the solenoids). We then gave each horse two generalization test sessions. Results indicated that the horses' behavior was effectively controlled by the training stimulus. Horses made the greatest number of responses to the training stimulus, and the tendency to respond to the other test stimuli diminished as the stimuli became farther away from the training stimulus. These findings are discussed in the context of behavioral principles and their relevance to the training of horses.
