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.

The first dedicated Life Sciences mission--Spacelab 4.

Spacelab is a large versatile laboratory carried in the bay of the Shuttle Orbiter. The first Spacelab mission dedicated entirely to Life Sciences is known as Spacelab 4. It is scheduled for launch in late 1985 and will remain aloft for seven days. This payload consists of 25 tentatively selected investigations combined into a comprehensive integrated exploration of the effects of acute weightlessness on living systems. An emphasis is placed on studying physiological changes that have been previously observed in manned space flight. This payload has complementary designs in the human and animal investigations in order to validate animal models of human physiology in weightlessness. The experimental subjects include humans, squirrel monkeys, laboratory rats, several species of plants, and frog eggs. The primary scientific objectives include study of the acute cephalic fluid shift, cardiovascular adaptation to weightlessness, including postflight reductions in orthostatic tolerance and exercise capacity, and changes in vestibular function, including space motion sickness, associated with weightlessness. Secondary scientific objectives include the study of red cell mass reduction, negative nitrogen balance, altered calcium metabolism, suppressed in vitro lymphocyte reactivity, gravitropism and photropism in plants, and fertilization and early development in frog eggs. The rationale behind this payload, the selection process, and details of the individual investigations are presented in this paper.

Peer training of safety-related skills to institutional staff: benefits for trainers and trainees.

A peer training program, in which experienced staff trained new staff, was evaluated as a method for teaching and maintaining safety-related caregiver skills in an institutional setting for the developmentally disabled. Three sets of safety-type skills were assessed in simulated emergency situations: responding to facility fires, managing aggressive attacks by residents, and assisting residents during convulsive seizures. Using a multiple-baseline research design, results indicated that the peer training program was an effective method of training the three types of emergency skills to new direct care staff. The program also appeared effective in improving the skills of the peer trainers. Perhaps most importantly, results indicated that if experienced staff functioned as peer trainers for particular emergency skills, then their proficiency in those skills maintained over time whereas their proficiency declined in emergency skills for which they did not act as peer trainers. Social validity information collected from available staff 23 months after the program was completed supported the utility of the training in terms of staff responses during actual emergencies. Also, acceptability measures indicated that staff liked participating in the program. However, some inconsistencies between staff verbal reports and performance-based measures of acceptability were noted. Results are discussed regarding the overall effectiveness of the peer training program, the importance of maintenance strategies for safety-related skills, and the need for multidimensional analyses of staff acceptability in staff training/management research.

A participative management approach for improving direct-care staff performance in an institutional setting.

The present study evaluated a participative management approach for increasing the frequency of interactions between institutional staff and severely/profoundly retarded residents. The participative management approach involved teaching staff how to use self-monitoring, standard setting, self-evaluation, and self-reinforcement procedures. These procedures were then used by staff with minimal involvement of supervisory personnel. Although supervisors provided feedback and praise to staff for using these self-management behaviors, feedback and praise were never dispensed contingent on staff interactions with residents. Results indicated that during the participative management program there was an increase in staff interactions that were contingent on appropriate resident behavior. The increase in this type of staff interaction was accompanied by an increase in appropriate resident behavior. Follow-up data on both staff and resident behaviors, although showing moderating trends, suggested generally good maintenance of the initial behavior changes. Acceptability data suggested that staff were quite receptive to the program. The advantages of participative management procedures for improving staff performance in residential settings are discussed.

An institutional staff training and self-management program for developing multiple self-care skills in severely/profoundly retarded individuals.

Although considerable attention has been given to the development of institutional staff training and management programs, the generalized effects of such programs on staff and resident behavior have seldom been examined. This study evaluated a program for teaching institutional staff behavioral training and self-management skills during self-care teaching sessions with severely and profoundly retarded residents. Following baseline observations in three self-care situations (toothbrushing, haircombing, handwashing), four direct care staff were sequentially taught to use verbal instruction, physical guidance, and contingent reinforcement in the toothbrushing program. During maintenance, staff were simultaneously taught to record, graph, and evaluate resident and their own behavior in the toothbrushing sessions. Staff were taught use of the training and self-management skills through a sequence of written instructions, videotaped and live modeling, rehearsal, and videotaped feedback. Observer presence and experimenter supervision were gradually decreased during the maintenance condition. Results indicated that during training and maintenance staff: (a) learned to use the training skills appropriately and consistently in the example situation (toothbrushing); (b) applied the skills in the generalization situations (haircombing and handwashing); and thereafter (c) maintained consistent and appropriate use of the skills with infrequent supervision. In addition, important changes in retarded residents' independent self-care responding occurred as staff training skills developed. Results are discussed in terms of their implications for future research and continued development of effective staff training and management programs.

Spacelab mission 4--the first dedicated life sciences mission.

Spacelab is a large, versatile laboratory carried in the bay of the Shuttle Orbiter. The first Spacelab mission dedicated entirely to life sciences is Spacelab-4. It is scheduled for launch in late 1985 and will remain aloft for 7 d. All of the investigations are currently classified as "tentatively selected," with "final selection" and confirmation planned for late 1983. The 24 tentatively selected investigations have been combined into a comprehensive, integrated exploration of the effects of acute weightlessness as living systems. An emphasis is placed on studying physiological changes previously observed in manned space flight. This payload has complementary designs in both human and animal investigations in order to validate animal models of human physiology in weightlessness. The experimental subjects include humans, squirrel monkeys, laboratory rats, two species of plants, and frog eggs. The primary scientific objectives include study of the acute cephalic fluid shift, cardiovascular adaptation to weightlessness (including postflight reductions in orthostatic tolerance and exercise capacity), and changes in vestibular function (including space motion sickness), associated with weightlessness. Secondary scientific objectives include the study of red cell mass reduction, negative nitrogen balance, altered calcium metabolism, suppressed in vitro lymphocyte reactivity, gravitropism and phototropism in plants, and fertilization and early development in frog eggs. The rationale behind this payload, the selection process, and details of the individual investigations are presented in this paper.

Protective equipment: continuous and contingent application in the treatment of self-injurious behavior.

This study evaluated the use of protective equipment in treating self-injurious behavior (SIB) exhibited by three retarded persons. In Experiment 1, the equipment was first applied continuously during 20-min sessions in individual multiple baseline designs across settings. Results showed substantial reductions in head hitting, eye gouging, and hand biting. Brief periods of time-out with the protective equipment were later made contingent on SIB and combined with a differential reinforcement procedure. Reduced levels of SIB was maintained with all subjects. Additionally, the amount of time during which the equipment was applied decreased as the SIB diminished. Experiment 2 evaluated the use of contingent protective equipment (the final condition in Experiment 1) when applied directly in the subjects' living units during the day. During Experiment 2, SIB remained at or below the levels found at the termination of Experiment 1. Finally, in an effort to assess the long-term effectiveness of the procedure, responsibility for implementation was given to the staff who were typically assigned to provide therapy to the subjects. Follow-up probe observations conducted up to 104 days after termination of the final experimental condition showed continued low levels of both SIB and equipment usage. Results of these experiments suggest that contingent protective equipment and differential reinforcement may be effective in reducing chronic self-injury.

Pyramidal training: a large-scale application with institutional staff.

This study evaluated an indirect method of training 45 institutional direct care staff to conduct behavioral programs. Three supervisors were trained to improve teaching behaviors (instructions, prompts, and consequence) used by the direct care staff while working with severely and profoundly handicapped residents. In addition to training, daily feedback was provided to supervisors regarding performance of their staff. Results of a multiple baseline analysis across teaching behaviors (instructions, prompts, and consequences) and content areas (communication and gross motor skills) showed that providing training and feedback to supervisors resulted in increases in correct teaching behavior by direct care staff. However, teaching behavior newly learned in one content area (communication) did not generalize to the other area (gross motor skills). Data collected on resident behavior showed small but noticeable improvement in terms of correct responses and attending behavior during programming. Results are discussed in terms of the benefits of a pyramidal approach to training institutional staff.

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.

Involving institutional staff in the development and maintenance of sign language skills with profoundly retarded persons.

A program to involve institutional staff in developing manual sign language skills with profoundly retarded persons was evaluated. In Experiment 1, six direct care staff, with close supervision, taught a small repertoire of signs to six profoundly retarded residents who had not benefited from previous training in vocal language. Training was conducted in a group format using instructions, modeling, manual guidance, contingent reinforcers, and feedback. During training, all residents learned to identify pictures of objects with manual signs. Generalization observations during unstructured times on the residents' living unit indicated that staff used their signing skills with the residents in addition to their vocal interactions but the residents did not increase their signing or vocalizing. In Experiment 2, the residents' skills in signing with real objects on their living unit as opposed to pictures of objects were evaluated and provided with additional training where necessary. Results indicated that all participating residents learned to communicate with signing during structured interactions on their living unit, and the skills maintained during follow-up assessments ranging from 39 to 49 weeks. Results are discussed regarding the variable generalization effects noted as well as the general benefits and disadvantages of teaching manual signing skills to profoundly retarded persons.

Evaluating a supervision program for developing and maintaining therapeutic staff-resident interactions during institutional care routines.

This study evaluated a program to teach and maintain language training interactions between institutional staff and profoundly handicapped children during a routine care task. Following baseline observations of bath sessions, staff were sequentially taught in multiple baseline fashion to vocalize more during the bath, praise child vocalizations, imitate sounds, and provide sound prompts. Procedures included a brief in-service meeting followed by a series of supervisory prompts and feedback. Results indicated that staff acquired the interaction skills in the bath sessions and that the skills generalized to another direct care task, dressing. The number of days on which components of supervision were implemented decreased from 47% of all days during the experimental conditions to 19% of the days during a 19-week maintenance period with no decrease in staff behavior. The interactions were shown not to interfere with the quality of the direct care task nor to increase the amount of time necessary to complete it. Also, some increases were noted for child vocalization frequencies. The advantages of providing therapeutic interactions during care routines are discussed along with the need for staff management techniques with long-term maintenance value.

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.

Use of a self-recording and supervision program to change institutional staff behavior.

The use of a self-recording and supervision program to increase interactions between direct care staff and profoundly retarded persons in a state residential facility was investigated. Following baseline, staff were provided with instructions regarding what to self-record, criteria for how many interactions to record, and a prepared card on which to make the recordings. Throughout the study, the staff supervisor monitored intermittently staff-client interactions. Observations indicated that when the staff recorded their interactions with clients in a loosely structured dayroom setting, the rate of interactions increased noticeably for each staff person. Behavioral ecology measures indicated that other staff responsibilities, such as maintaining the cleanliness of residents and the physical area, were not affected detrimentally when social interactions increased and actually showed small improvements. Additionally, small decreases in resident self-stimulatory and disruptive/aggressive behaviors occurred when the rate of social interactions from staff persons increased. Follow-up measures indicated that the rate of staff self-recording was variable, but when staff did self-record, the increased rate of staff-client interactions maintained.

Teaching foster grandparents to train severely handicapped persons.

Five foster grandparents were taught training skills for use in their daily interactions with severely handicapped persons in an institution. Following baseline, specific teaching procedures consisting of teacher instructions, prompts, modelling, and praise were implemented. The grandparents' frequency of training three skill areas increased as the specific teaching was implemented in multiple-baseline format. The total amount of training continued as teacher instructions, prompts, and modelling were terminated and praise continued, although the grandparents spent their training time emphasizing only two of the three skill areas. Teacher presence was gradually reduced over an 11-week period, with no decrease in grandparents' frequency of training. Four of the foster grandchildren, all profoundly retarded and multiply handicapped, demonstrated progress throughout the study. Results were discussed in light of the available contributions of foster grandparents in institutional settings and maintenance of staff training.

Teaching retarded women a clothing selection skill using community norms.

Five institutionalized retarded women were taught a clothing selection skill to coincide with popular fashion. Normative data concerning popular styles of color-coordinated clothing were collected through observations of women's apparel in a local community. Using a puzzle simulation of a woman with alternative pieces of colored clothing, color coordination training was conducted using modelling, instructions, practice, praise, and feedback to teach popular selections of color combinations. A generalization training component with actual clothing was also included. Training was accompanied by large increases in percentage of popular color selections with the puzzle and actual clothing. The increases maintained over a seven- to 14-week followup period. Time efficiency measures supported the use of the simulation procedure as opposed to total reliance on actual clothing. The results underscore the utility of local norms in community preparation programs and the efficacy of instructional procedures for severely and profoundly retarded persons as part of their participation in the deinstitutionalization movement.

Teaching nonvocal communication skills to multihandicapped retarded adults.

A training program for teaching communication skills to nonvocal retarded adults was evaluated in three experiments. The four subjects were severely disabled physically and had never demonstrated functional speech. Each person was taught to use either a prosthetic head pointer or to point with a hand in using a communication board for expressive language. Following baseline in Experiment I, coordination training was implemented, consisting of instructions, manual guidance, praise, feedback, and practice. Each person demonstrated a higher frequency of accurate pointing to designated areas on the board during coordination training than during baseline. In Experiment II, identification training, consisting of instructions, praise, feedback, and practice was introduced after baseline. Subjects pointed more frequently to specific word-photograph combinations to correspond to descriptive verbal labels after introduction of identification training. Social validation measures in Experiment III indicated that the communication board skills were functional in providing a method of expressing a choice of a leisure activity to people who previously could not understand the subjects' communication attempts. The acquired skills maintained throughout a seven-week followup period.
