LEISURE-DANCE INSTRUCTION FOR SEVERELY AND PROFOUNDLY RETARDED PERSONS: TEACHING AN INTERMEDIATE COMMUNITY-LIVING SKILL

We evaluated an approach for teaching an intermediate community living skill via a leisure-dance activity to institutionalized severely and profoundly retarded persons. The targeted skill was considered as intermediate in contrast to a community living skill per se because it was based on successful performances of higher functioning, noninstitutionalized retarded persons as opposed to nonhandicapped individuals. Definitions for appropriate dancing were established and then validated through observations of the performance of retarded persons living in the local community. The dance skills were then taught to four participants through serial training in leg movements, arm movements, and coordinated leg and arm movements, plus follow-up trainer supervision. Generalization was also programmed by way of multiple trainers and training settings. Results during structured assessments showed that all four residents acquired the dance skills and that both serial training and follow-up supervision were necessary for skill acquisition. Generalized increases in appropriate dancing at dances attended by the participants and retarded persons from the community were also demonstrated. However, in most cases some active supervision by caregivers was needed to enhance the generalized improvements. Results are discussed in terms of the applicability of this approach for validating goals when training other community-related skills to low-functioning populations.     

AN ANALYSIS OF A GROUP TEACHING PROCEDURE FOR PERSONS WITH DEVELOPMENTAL DISABILITIES

This study evaluated whether a concurrent group teaching procedure, in which all students respond simultaneously, could be used for persons with moderate or severe mental retardation. The teaching procedure used was the Task Demonstration Model, a program based on stimulus-control research and the fading techniques of behavioral psychology. Three teachers and three groups of students participated. Results showed that the teachers increased their rates of questions and instructions, positive feedback, and use of functional materials, but they reduced their rate of prompts to almost zero. Students increased their percentage and rate of correct responding as well as their engaged time. In addition, maladaptive responding, for which there were never any direct consequences, decreased from 45% to 10% for 8 of the 14 students. Results are discussed primarily in two areas: (a) changing stimulus control from teacher prompts to critical elements of the items being taught, and (b) reasons for the reduction of maladaptive behavior for 8 of the subjects.     

PROVIDING A LESS RESTRICTIVE ENVIRONMENT FOR PROFOUNDLY RETARDED PERSONS BY TEACHING INDEPENDENT WALKING SKILLS

A basic right of all handicapped persons is to live in the least restrictive environment possible. In this investigation, procedures were evaluated for teaching four institutionalized males with profound retardation necessary skills to increase their individual freedom of movement. Following baseline, a travel training program with a backward chaining format was implemented to teach each person to walk independently from his living area to school. Travel training included instructions, practice, praise, feedback, verbal reprimands, prompts, and edible reinforcers. Each resident began walking the entire distance to school independently during training and also began walking back to the living area, although the latter set of skills was not specifically trained. Following termination of the formal investigation, follow-up measures of 1 to 8 weeks showed the residents continued going to school independently. A survey of residential facilities in 43 states provided social validation for the seriousness of the problems associated with transporting seriously retarded persons to school. Also, time efficiency measures indicated that training independent travel resulted in reductions of staff time required in school transportation. Results were discussed in light of the potential contributions of behavior analysis in providing less restrictive environments for seriously handicapped persons.     

AN OPERANT TRACKING PROCEDURE IN THE AUDITORY ASSESSMENT OF PROFOUNDLY RETARDED INDIVIDUALS

The present study investigated a discrete-trials, operant tracking and a descending-series procedure for the determination of hearing levels with profoundly retarded individuals. These individuals were previously diagnosed as untestable. Following stimulus-control training with errorless discrimination procedures, hearing levels for each individual were examined with both procedures. For P-1 and P-2, the operant tracking procedure was administered following a descending-series procedure. Both were observed to “track” their own hearing levels. For P-3, the operant tracking procedure was administered first, followed by the descending-series procedure. Although P-3 also “tracked” her own hearing level, more variable responding was observed. Nonetheless, the operant tracking procedure proved quite workable and may provide for improved hearing testing with “difficult-to-test” individuals.     

NORMALIZATION OF INSTITUTIONAL MEALTIMES FOR PROFOUNDLY RETARDED PERSONS: EFFECTS AND NONEFFECTS OF TEACHING FAMILY-STYLE DINING

Benefits have been reported for certain institutionalized populations when mealtimes are arranged under normal, family-style conditions. In this study, we evaluated a program for teaching family-style mealtime skills to institutionalized persons with skill deficits greater than those targeted in previous research—the profoundly retarded. Results showed that the program, involving forward chaining with a less-to-more intrusive prompting sequence and contingent reinforcement, successfully taught four profoundly retarded persons several family-style skills. Also, systematic measures supported the durability of the skills, social validity of the behavior changes; Final acceptance of the program by staff trainers, and no detrimental changes in health-related variables associated with food consumption. However, results also indicated that beneficial corollary changes (e.g., increased peer communication) previously reported with higher skilled populations did not occur. These results suggest that with more seriously handicapped populations, multiple changes should not be assumed when normalizing institutional conditions; rather, specific skill training will probably be necessary.     

OVERCORRECTION: GENERALIZATION AND MAINTENANCE1

The present study examined the effects of one component of overcorrection—verbal reprimands—and compared them with the effects of the entire overcorrection procedure. Generalization and maintenance of effects were also evaluated. A combined reversal and multiple-baseline experimental design was used to evaluate the effect of the various contingencies on the inappropriate searching behavior of a severely and profoundly mentally retarded adult living in a group home. Searching was defined as carefully and thoroughly touching floors, sofas, cabinets, etc. Data were collected by group-home personnel during three separate observation periods each day of the 115-day study: before breakfast, after breakfast, and after dinner. Observers also served as experimenters. Following an initial baseline phase, verbal reprimands followed searching behavior during two daily experimental periods in multiple-baseline fashion. An immediate reduction of searching during experimental periods occurred with the onset of verbal reprimands. No reduction was observed in the third daily observation period, the control session. After a second baseline phase, during which searching behavior was not shown to return to the original baseline levels, overcorrection procedures (washing hands) were instituted. Overcorrection virtually eliminated inappropriate searching during both daily experimental periods. Further, the effects generalized to the daily control session. In a final experimental phase, decreased searching behavior was maintained with verbal reprimands alone.     

TEACHING PEDESTRIAN SKILLS TO RETARDED PERSONS: GENERALIZATION FROM THE CLASSROOM TO THE NATURAL ENVIRONMENT1

Little attention has been given to teaching adaptive community skills to retarded persons. In this study, five retarded male students were taught basic pedestrian skills in a classroom. Training was conducted on a model built to simulate city traffic conditions. Each subject was taught five specific skills involved in street crossing in sequence, viz. intersection recognition, pedestrian-light skills, traffic-light skills, and skills for two different stop-sign conditions. Before, during, and after training, subjects were tested on generalization probes on the model and under actual city traffic conditions. Results of a multiple-baseline design across both subjects and behaviors indicated that after receiving classroom training on the skills, each subject exhibited appropriate pedestrian skills under city traffic conditions. In addition, training in some skills appeared to facilitate performance in skills not yet trained.     

ELIMINATING DISCIPLINE PROBLEMS BY STRENGTHENING ACADEMIC PERFORMANCE1

Behavior modification procedures have typically been used to eliminate discipline problems in the classroom through reinforcement of nondisruptive behavior. This report demonstrates an alternative approach whereby discipline problems are eliminated by reinforcing relevant academic skills. Five fifth-grade boys, identified by their teacher as discipline problems, were observed. The teacher conducted 15-min performance sessions in her reading class during which written academic performance and disruptive behavior were recorded. These measures indicated that the boys' average level of disruption was 34%, while their reading performance was below 50%. When systematic token reinforcement was applied to reading performance only, the rate of disruption fell drastically, and reading performance increased. When the reinforcement procedure was withdrawn, disruption again rose, and reading performance declined. The reinstatement of reinforcement doubled reading performance and eliminated disruption.     

ATTENTION TRAINING: THE USE OF OVERCORRECTION AVOIDANCE TO INCREASE THE EYE CONTACT OF AUTISTIC AND RETARDED CHILDREN

A crucial first step in teaching and training the retarded and autistic is to develop and maintain eye contact with the therapist. Functional movement training (an overcorrection procedure) plus edibles and praise were compared with edibles and praise alone as a method of developing eye contact in three such children. In both conditions, the child was given food and praise when eye contact occurred within 5 sec of the therapist's verbal prompt: “Look at me.” Functional movement training avoidance plus edibles and praise produced about 90% attention for the three children, while edibles and praise alone were less effective (eye contact never exceeded 55%). Functional movement training avoidance combined with edibles and praise appears to be an effective method of teaching eye contact and possibly other forms of instruction-following to behaviorally disordered children who are not always responsive to positive consequences.     

GENERALIZATION AND TRANSFER BETWEEN COMPREHENSION AND PRODUCTION: A COMPARISON OF RETARDED AND NONRETARDED PERSONS

The study compared the acquisition, generalization, transfer, and maintenance of language comprehension and production responses by persons at two IQ levels: mentally retarded (N = 10) and nonretarded (N = 10). The two levels of the IQ Level factor were combined factorially with two levels of a Training Condition factor: Comprehension-Production and Production Only. Participants in the former groups were trained sequentially to (a) comprehend coin labels by pointing, and then (b) produce verbally the correct coin label. Participants in the Production Only groups were trained on the latter response only. A three-factor mixed design with one repeated measure plus a multiple baseline across coin responses was employed. Results indicated that both mentally retarded and nonretarded subjects attained a high level of acquisition and maintained their performance on 1- and 4-week follow-up tests. No difference occurred between mentally retarded and nonretarded participants in magnitude of acquisition, but the mentally retarded groups took approximately three times as many trials to complete training. Data also suggested, contrary to past research, that generalization from comprehension to production was bidirectional, with no difference in magnitude between mentally retarded and nonretarded subjects. Transfer from comprehension to production occurred in both nonretarded and retarded subjects; comprehension training facilitated a savings of trials in production training. These results show that language differences between retarded and nonretarded persons are quantitative rather than qualitative as some past research may have suggested.     

NATURALISTIC OBSERVATIONS OF INSTITUTIONALIZED RETARDED PERSONS: A COMPARISON OF LICENSURE DECISIONS AND BEHAVIORAL OBSERVATIONS

In the last several years, various organizations have produced strikingly similar documents by which institutions for retarded persons are judged for licensure. The purpose of the present study was to determine whether residential units that were licensed differed from residential units that were not licensed in terms of the active programming behaviors of their staff and residents. Data were collected through a time-sampling procedure that yielded about 160,000 observations on eight staff and six resident behaviors. Results showed that the licensed units were just as derelict as unlicensed units in providing habilitative programming for their retarded residents. Maladaptive responding by residents occurred at least as much as task-related behaviors: residents spent as much time self-stimulating as they did in programming; they also engaged in self-abusive behavior about as much time as they engaged in on-task responding. Results were discussed in terms of the failure of governmental regulations that are not based on observation to adequately assess habilitative programming.     

CONTINGENT OBSERVATION: AN EFFECTIVE AND ACCEPTABLE PROCEDURE FOR REDUCING DISRUPTIVE BEHAVIOR OF YOUNG CHILDREN IN A GROUP SETTING1

Since a major task of childhood is learning to get along in a group without disrupting other children's activities, caregivers need explicit guidelines for gentle but effective procedures for dealing with disruptive behaviors in child-care settings. In a day-care center for normal 1- and 2-yr-old children, an effort was made to develop a procedure that appeared sufficiently humane and educational to be acceptable to parents and daycare workers, and yet effective in reducing disruptive play behaviors. Caregivers used the occasion of disruptive behavior to instruct the child in appropriate alternatives, then had the child sit on the periphery and observe the appropriate social behavior of the other children, “sit and watch”, for a brief period before inviting him or her to rejoin the play activities. The effectiveness of this procedure was compared with a method commonly recommended for use with young children: instructing the child, then distracting or redirecting the child to an alternative toy or activity. Contingent observation, combining instruction with a brief timeout (from being a participant in an activity to becoming an observer of the activity), proved considerably more effective in maintaining low levels of disruptions and was considered by caregivers and parents to be an appropriate and socially acceptable method of dealing with young children's disruptive behaviors. Therefore, contingent observation can be recommended for general use in day-care programs for young children.     

INCREASING HABILITATIVE SERVICES FOR PERSONS WITH PROFOUND HANDICAPS: AN APPLICATION OF STRUCTURAL ANALYSIS TO STAFF MANAGEMENT

We evaluated a structural analysis methodology for enhancing the utility of a staff management program. In Experiment 1, a structural analysis of direct-care staff behavior in a mental retardation facility revealed differences in work patterns over time. Specific times were identified when few basic care duties were necessary and staff engaged in nonwork activity. In Experiment 2, a management program was implemented to increase staff members' training activities during periods identified through the structural analysis. The program was accompanied by increases in training activities and decreases in nonwork behavior. The improvements were maintained during a 43-week period while the most labor-intensive component of the program was withdrawn. Staff acceptability measures indicated a positive response to the management intervention, although responses varied across components within the multifaceted program. The increased training was accompanied by beneficial changes among clients with profound handicaps. Results are discussed regarding practical considerations for improving staff performance and for adopting innovations resulting from applied research.     

PUPILS' SELF-SCORED ARITHMETIC PERFORMANCE: A PRACTICAL PROCEDURE FOR MAINTAINING ACCURACY1

Scoring of student performance is often costly in teacher time. Self-rating may be a practical alternative, if ratings are accurate. Some conditions affecting self-rating accuracy were examined in two special-education classes in two experiments. The first assessed the separate effects of submitting self-ratings to the teacher and token reinforcement for those ratings. Actual and self-rated performance during daily 20-minute arithmetic assignments were observed in a class of four boys with an average age of 10 years, four months. Subjects answered assignments in pen for later detection of falsified answers. At the end of the session, correct answers were projected and papers self-scored in pencil. During class dismissal, the experimenter surreptitiously scored actual performance. Three experimental conditions were introduced in an A B C B A design. During A, subjects self-rated but submitted no report, nor received token reinforcement. During B, self-ratings were reported to the teacher on a folded slip of paper, without reinforcement. During C, points were awarded for self-reported scores based on changes in individual performance from the prior condition and later exchanged for prizes. Subjects self-rated accurately during A, with little change during B. However, awarding points for self-reported scores in C, produced highly exaggerated performance. There was little change in correct arithmetic performance throughout the experiment. The second experiment examined a low-cost procedure to produce and maintain a low level of exaggeration in a class of 17 boys with an average age of 15 years, three months. Continuous, then intermittent checks on the accuracy of self-rated arithmetic performance were assessed in a multiple-baseline design across groups of subjects. Following a condition where subjects' self-reported performance was reinforced as in the first experiment, the self-rating accuracy of all subjects was checked publicly and a penalty applied for inaccuracies or bonus points for accuracies (Maximum Checks). During Minimum Checks, the self-rating accuracy of one randomly selected subject was checked. The reduction in checking frequency was gradual for one group and abrupt for the other. When self-reports were reinforced, 13 of the 17 pupils submitted ratings discrepant with actual arithmetic performance by more than two problems per session. Maximum Checks reduced discrepancies below two problems per session for 15 of the 17 pupils. This same low level of exaggeration was maintained during Minimum Checks for 14 of the 17 pupils. Correct arithmetic performance showed no systematic change. Teachers reported that self-rating resulted in time savings over their usual methods of scoring. The results indicated that pupils exaggerate when rewarded for self-ratings. Exaggeration was reduced and maintained at low levels by infrequent accuracy checks.     

PERSONS IN NATURE: TOWARD AN APPLICABLE AND UNIFIED ENVIRONMENTAL ETHICS

Abstract. Two major contenders for the role of robust environmental ethics claim our allegiance. One is Baird Callicott's, based on the land ethic formulated by Aldo Leopold; the other is that of Holmes Rolston, 111, sharply distinguishing environmental from social (human) ethics. Despite their many strengths, neither gives us the vision we need. Callicott's ethic leaves too much out of his picture; Rolston's leaves too much disconnected between nature and humankind. A really usable environmental ethic needs to be both comprehensive and integrated. For that, we need a worldview that includes the human in nature but also affirms the unique values of personhood.     

INCREASING VERBAL INTERACTION AMONG ELDERLY SOCIALLY ISOLATED MENTALLY RETARDED ADULTS: A GROUP LANGUAGE TRAINING PROCEDURE

The present study examined the effectiveness of a group language training procedure for directly increasing and generalizing the rate of verbal interaction among four elderly, socially isolated, moderately mentally retarded men. A withdrawal of treatment design was used to examine the effect of the procedure that used verbal prompts, behavioral rehearsal, and contingent social praise. Changes in behavior were examined in two generalization settings, one similiar to the training environment (Generalization I) and the other arranged as part of the subjects' daily routine (Generalization II). Baseline data indicated no verbal interaction among the subjects. During treatment the training procedure increased the rate of subjects' verbal interactions not only in the training situation, but also in the two generalization settings. An analysis of the data obtained during the Generalization II situation indicated that subjects' verbal interaction increased not only among themselves, but with nonsubject peers present in this setting. Follow-up data showed that increases in rates of verbal interaction were maintained four months after the cessation of training. The implications of the results for program generalization and work with the language deficient individual is discussed.     

A NOTE ON TRANSFER OF STIMULUS CONTROL IN THE DELAYED-CUE PROCEDURE: FACILITATION BY AN OVERT DIFFERENTIAL RESPONSE

This case study describes initially unsuccessful attempts to use the delayed-cue procedure to teach conditional discriminations to an individual with moderate mental retardation. The task was matching printed-word comparison stimuli to dictated-name sample stimuli. In three experiments, the subject typically waited for the delayed cue unless differential responses to the dictated samples (repeating the sample names) were required. Hence, the study provides an example of a way to make the delayed-cue method more effective. The stimulus control bases for the results are discussed.     

AUGMENTING SIMPLIFIED HABIT REVERSAL WITH AN AWARENESS ENHANCEMENT DEVICE: PRELIMINARY FINDINGS

The chronic hair pulling of a 36-year-old woman with moderate mental retardation was initially treated with a simplified habit-reversal (SHR) procedure that consisted of awareness training, competing response training, and social support. When SHR did not produce large and sustained reductions in hair pulling, an awareness enhancement device was added, and it reduced hair pulling to near-zero levels in two settings. The results are discussed, and directions for future research with this device are provided.     

AINSWORTH'S STRANGE SITUATION PROCEDURE: THE ORIGIN OF AN INSTRUMENT

The American‐Canadian psychologist Mary Ainsworth (1913–1999) developed the Strange Situation Procedure (SSP) to measure mother‐child attachment and attachment theorists have used it ever since. When Ainsworth published the first results of the SSP in 1969, it seemed a completely novel and unique instrument. However, in this paper we will show that the SSP had many precursors and that the road to such an instrument was long and winding. Our analysis of hitherto little‐known studies on children in strange situations allowed us to compare these earlier attempts with the SSP. We argue that it was the combination of Ainsworth's working experience with William Blatz and John Bowlby, her own research in Uganda and Baltimore, and the strong connection of the SSP with attachment theory, that made the SSP differ enough from the other strange situation studies to become one of the most widely used instruments in developmental psychology today.     

A PROGRAM FOR INCREASING MANUAL SIGNING BY AUTISTIC AND PROFOUNDLY RETARDED YOUTH WITHIN THE DAILY ENVIRONMENT

A program was implemented to increase the manual signing of five profoundly retarded and four autistic youth within their daily environment. Each participant was nonvocal or minimally vocal. The program was based on modified incidental teaching strategies and was implemented by direct care personnel under supervision in an institutional setting. Specific components included rearranging the physical environment to prompt signing, altering routine staff-resident interactions to prompt, manually guide and/or reinforce signing; and conducting mini-training sessions. Additionally, staff modeled signs intermittently throughout the day. The program was sequentially implemented during two staff work shifts on each of two resident living modules. Observations conducted at four separate time periods during the day indicated that significant increases in signing occurred for all participating youth and that the increases generally maintained during follow-up checks at 5 and 17 weeks. Differential effects of the increased signing on frequency of vocalizations were noted across residents. A staff acceptability survey indicated favorable staff reports on the usefulness of signing to communicate with the youth. Results are discussed regarding the significance of manual signing for seriously developmentally disabled persons and the importance of ensuring that signing skills are used in the daily environment and not exclusively in formal training sessions. Also, areas for continued research are noted in terms of more refined analyses of client skills and subsequent progress in manual communication programs.
