Functional communication training has been reported to be a promising treatment for severe behavior problems. In this study, functional communication training alone and combined with extinction and/or punishment was evaluated for 4 clients with severe retardation, behavior problems, and communication deficits. The participants were inpatients on a hospital unit for treatment of severe behavior disorders. They received individualized interventions based on functional assessment that included reinforcement of a communication response with the same function as their destructive behavior. Results showed that for some patients, functional communication training was not sufficient to produce clinically significant reductions in destructive behavior, and the combination of training plus punishment produced the largest and most consistent reductions.
The effectiveness of a training package on the social behaviors of 20 hearing-impaired children with severe language disabilities was assessed. The package consisted of initial instruction in role-play situations, reinforcement of appropriate instances of the behaviors, and a correction procedure following inappropriate instances of the behaviors. Results showed that the training package was effective in increasing greeting, turn waiting, initiating interaction, and giving help and these effects were maintained over several weeks.
We taught 4 students with profound multiple disabilities to use a microswitch communication system to request a change in recreational stimuli during social interactions with nondisabled peers. In Study 1, we conducted a preference assessment across a range of stimuli for each student. The most and least preferred stimuli were incorporated into microswitch communication system training in Study 2. During the second study, 3 of the 4 students (a) learned to use the microswitch communication system to control stimulus presentation, (b) more clearly differentiated their time among stimuli, and (c) increased their level of general alertness. Study 3 extended the use of the microswitch communication system to social interactions with nondisabled peers. Two students were more engaged in interactions when they chose when to change stimuli; 1 student was more alert when a peer chose when to change activities; a 4th student showed an undifferentiated pattern. The outcomes of the investigation are discussed in terms of the effects of controlling stimulus presentation on the behavior of students with profound multiple disabilities and the stability of preference hierarchies over time.
Computer-based instruction may yield widely useful handwritten spelling. Illustrative cases involved individuals with mental retardation and hearing impairments. The participant in Study 1 matched computer pictures and printed words to one another but did not spell the words to pictures. Spelling was then taught using a computerized procedure. In general, increases in the accuracy of computer spelling were accompanied by improvements in written spelling to pictures. Study 2 extended these results with a 2nd participant. After initial training, spelling improved in the context of a retrieval task in which the participant (a) wrote a list of the names of objects displayed on a table, (b) selected the objects from a shelf, and (c) returned the objects to the table. Nearly perfect accuracy scores declined on some retrieval trials conducted without a list, suggesting that the list may have served a mediating function during retrieval. Transfer of stimulus control of computer-based teaching to the retrieval task may have been attributable to the existence of stimulus classes involving pictures, objects, and printed words.
We conducted functional analyses of aberrant behavior with 4 children with developmental disabilities. We then implemented functional communication training (FCT) by using different mands across two contexts, one in which the establishing operation (EO) that was relevant to the function of aberrant behavior was present and one in which the EO that was relevant to the function of aberrant behavior was absent. The mand used in the EO-present context served the same function as aberrant behavior, and the mand used in the EO-absent context served a different function than the one identified via the functional analysis. In addition, a free-play (control) condition was conducted for all children. Increases in relevant manding were observed in the EO-present context for 3 of the 4 participants. Decreases in aberrant behavior were achieved by the end of the treatment analysis for all 4 participants. Irrelevant mands were rarely observed in the EO-absent context for 3 of the 4 participants. Evaluating the effectiveness of FCT across different contexts allowed a further analysis of manding when the establishing operations were present or absent. The contributions of this study to the understanding of functional equivalence are also discussed.
We evaluated the effects of a dense (fixed-ratio 1) schedule of reinforcement for an 11-year-old boy's mands for toys while aggression produced the same toys on various schedules chosen on the basis of a progressive-ratio probe. Based on the probe session data, we accurately predicted that aggression would be more probable than mands when the schedules were equal or slightly discrepant, but that mands would be more probable when the schedule discrepancy was large.
35 deaf students completed the Self-description Questionnaire I and their teachers completed the Meadow/Kendall social-emotional inventory for deaf students. Significant positive but small correlations were found among reading scores, reading appraisals, and social-emotional adjustment inferences. Achievement, particularly reading, appears associated with concepts of self.

23 educators and therapists of children with autism were surveyed about their beliefs and use of Facilitated Communication, a technique previously shown to have questionable scientific validity. 65.2% or 15 use the procedure often or very often in their work with children. Some factors that appeared related to this choice were beliefs consistent with those of proponents of Facilitated Communication, less education, belief in the notion that individuals with autism were more intelligent than their behavior indicated, and lack of belief in science as a source of explanation of human behavior. It was concluded that supervisors need to be more informing about the scientific validity of techniques used by their employees.
A group intervention program was designed to initiate an active search for solutions to listening and communication problems among hearing-impaired workers. Six groups of 8 workers were recruited from different areas of the Province of Québec. The workers were males; they had hearing threshold levels equal to or higher than 30 dB averaged over 0.5, 1, 2 and 4 kHz in at least one ear. The recruitment was conducted by occupational health nurses of local community health centers. The workers were invited to a group meeting with their spouses by means of a home interview. Three groups met during 2-hour weekly evening sessions, and three groups during a 1.5-day weekend session. A follow-up was conducted over a period of 3 months ending with an evaluation meeting. Results based on responses to a handicap questionnaire showed that the workers judged their hearing problem as being significantly less severe after their participation in the session. Group interviews showed that, although they were more conscious of their hearing difficulties, they agreed on being much more confident in dealing with them. Different steps were taken towards improving their situation, including disclosure of their hearing impairment to others, making requests to conversational partners to facilitate communication, and acquiring instrumental aids.
A summary is presented of available information regarding the special characteristics and needs of hearing-impaired alcoholics and drug addicts. The various obstacles to this population receiving treatment are seen to be made even more formidable by apparent minimal adherence in the chemical dependency field to the legal mandate that agencies and institutions that receive federal funding must provide services that are accessible to disabled persons. The Illinois Task Force on Substance Abuse Among the Hearing Impaired was established to examine the needs of this population in Illinois. The results of a needs assessment conducted by the Task Force are summarized. The conclusion is reached that the minimal accessibility of hearing-impaired individuals to substance abuse treatment reported in the literature extends to Illinois as well. The concerns of agencies in attempting to meet the needs of this population are cited. Specific recommendations are made to changes in programming intended to improve the level of substance abuse services accessible to hearing-impaired individuals.
Data collected on the use of hearing aids by 680 school-aged hearing-impaired subjects are examined and aid use is related to gender, age, hearing loss, age at onset, aetiology, age at diagnosis, educational setting, method of communication, primary language in the home, hearing status of parents and additional handicaps. The likelihood of a student wearing an aid is significantly related to certain educational settings, the degree of hearing loss, age and to a lesser extent, his method of communication.
A system to provide hearing-impaired persons with adequate assistive devices is described. Investigation of 100 persons' recommended devices in 1985 shows that the system functions reasonably well. To secure provision of adequate devices, a system must be established to take care of all practical tasks. The mean expense to supply a hearing-impaired person with the assistive devices needed was found to be 764 pounds. Supplying elderly hearing-impaired persons with assistive devices may enable them to stay at home longer. The cost of the required assistive devices for a hearing-impaired person is on average approximately the same as for 8 days' stay in a nursing home.
