Counselling with a profoundly deaf client and the impact of a therapist's dream: A case study

This case study explores the experience of one client participating in a project evaluating the use of dreams in short‐term counselling within the National Health Service. The client received 24 sessions of counselling and completed a post‐counselling semi‐structured questionnaire. This was followed by a semi‐structured interview, which confirmed the internal coherence within the participant's narrative and allowed a more detailed exploration of her experiences, supported by process notes. Supervision challenged the therapist's preconceptions and held her in her uncertainty until the work was aided by a dream that the therapist had of the client.     

Spinal kinematics during gait in healthy individuals across different age groups

Most studies investigating trunk kinematics have not provided adequate quantification of spinal motion, resulting in a limited understanding of the healthy spine’s biomechanical behavior during gait. This study aimed at assessing spinal motion during gait in adolescents, adults and older individuals.Fourteen adolescents (10–18 years), 13 adults (19–35 years) and 15 older individuals (≥65 years) were included. Using a previously validated enhanced optical motion capture approach, sagittal and frontal plane spinal curvature angles and general trunk kinematics were measured during shod walking at a self-selected normal speed.Postural differences indicated that lumbar lordosis and thoracic kyphosis increase throughout adolescence and reach their peak in adulthood. The absence of excessive thoracic kyphosis in older individuals could be explained by a previously reported subdivision in those who develop excessive kyphosis and those who maintain their curve. Furthermore, adults displayed increased lumbar spine range of motion as compared to the adolescents, whereas the increased values in older individuals were found to be related to higher gait speeds. This dataset on the age-related kinematics of the healthy spine can serve as a basis for understanding pathological deviations and monitoring rehabilitation progression.     

AN EXPERIMENTAL ANALYSIS OF FACILITATED COMMUNICATION

We evaluated the authorship of messages produced through facilitated communication by 7 adults with moderate or severe mental retardation and their facilitators. The clients had been reported to be communicating fluently through facilitated communication. We controlled the facilitators' access to information to be communicated in two evaluation formats, naming pictures and describing activities. In both formats we conducted three conditions: (a) the facilitator and client had access to the same information, (b) the facilitator did not have access to the picture or activity, and (c) the facilitator was given false information about the picture or activity. The results showed that the clients typed the correct answer only when the facilitator had access to the same information, never typed the correct answer when the facilitator had no information or false information, and typed the picture or activity presented to the facilitator when it was different from the one experienced by the client. These results provide unequivocal evidence for facilitator control of typing during facilitated communication.

TRAINING APARTMENT UPKEEP SKILLS TO REHABILITATION CLIENTS: A COMPARISON OF TASK ANALYTIC STRATEGIES

The research was designed to validate procedures to teach apartment upkeep skills to severely handicapped clients with various categorical disabilities. Methodological features of this research included performance comparisons between general and specific task analyses, effect of an impasse correction baseline procedure, social validation of training goals, natural environment assessments and contingencies, as well as long-term follow-up. Subjects were taught to perform upkeep responses on their air conditioner-heating unit, electric range, refrigerator, and electrical appliances within the context of a multiple-probe across subjects experimental design. The results showed acquisition, long-term maintenance, and generalization of the upkeep skills to a nontraining apartment. General task analyses were recommended for assessment and specific task analyses for training. The impasse correction procedure generally did not produce acquisition.     

AN EVALUATION OF THE RELATIONSHIP BETWEEN RECEPTIVE SPEECH SKILLS AND EXPRESSIVE SIGNING

We examined the effects of receptive speech on the acquisition of manual signing among three mentally retarded children. In an alternating treatments design, we compared the acquisition of expressive signs that were, versus were not, in a child's receptive vocabulary. The children were trained via total communication in which pictorial referents were named during sign training. Signs corresponding to known words were generally acquired faster and retained better than signs corresponding to unknown words. We conducted posttests to assess the stimulus control of signing and any changes in expressive and receptive signing and speech. Observed changes in performance could be accounted for by attention to aspects of the stimulus complex during training and functional equivalence of stimuli established by training.     

THE USE OF PEER MONITORS TO REDUCE NEGATIVE INTERACTION DURING RECESS

The negative interactions of a mildly retarded child, Dennis, were reduced in three daily recess periods, withthe use of a point system. Adult monitors initiatedthe intervention inthe morning recess; reductions achieved during adult monitoring were maintained in that recess during two subsequent conditions: peer monitoring and self-monitoring. Dennis' negative interactions were reduced next inthe afternoon recess by peer monitors. Again, reductions were maintained during a subsequent self-monitoring condition. Finally, duringthe noon recess, Dennis was trained to serve as a peer monitor for Ed, a moderately retarded classmate. Dennis' rate of negative interactions quickly decreased following his appointment as a peer monitor. The results show that a point system, originally designed for adult monitoring, can be adapted without loss of program effectiveness for peer monitoring or self-monitoring. The results also suggest that classmates who serve as peer monitors may benefit significantly from their role. The conditions under which these therapeutic effects occur andthe role that treatment order effects may play in this process require further investigation.     

A parametric analysis of the relationship between food quantity and rumination

Rumination is the chronic regurgitation, chewing, and reswallowing of previously ingested food. The study reported here, using a parametric design, examined the control of rumination by the quantity of food eaten at meals. The subjects were three profoundly retarded individuals who chronically emitted this behavior. The quantity of food by weight ingested daily was varied in 10-oz steps in both ascending and descending series (data were collected only after breakfasts and lunches). Ruminating decreased when food quantity increased and increased when food quantity decreased. In addition, there was a similar inverse interaction between breakfast food quantity and post-lunch ruminating. The data showed relatively rapid transitions in both frequency and duration at each meal size for all subjects. The data establish a clear functional relation between the quantity of food ingested and ruminating.     

BUILDING RESPONSE CLASSES: A COMPARISON OF TWO PROCEDURES FOR TEACHING GENERALIZED POURING TO LEARNERS WITH SEVERE DISABILITIES

Five individuals with profound mental retardation received instruction on liquid pouring. The effects of two training strategies on performance with nontrained pitchers and receptacles were compared within a split multiple baseline design across subjects. One training approach followed general case instruction guidelines in which both difficult and easy teaching examples were selected that sampled the range of relevant stimulus and response variation. The second training approach approximated the early steps in an easy-to-hard sequencing strategy and involved using only a set of easy teaching examples that did not sample the full range of relevant stimulus and response variation required for successful pouring in natural settings. Results indicated that only after training with the full set of general case examples did the learners become competent with the nontrained generalization probe tasks. In addition, the set of easy examples resulted in learners performing topographically predictable errors with the generalization probe tasks.     

Conditional discrimination in mentally retarded adults: the effect of training the component simple discriminations.

Two subjects with retardation who exhibited generalized identity matching, but who had extensive histories of failure to acquire arbitrary matching, were exposed to a series of conditions designed to train separately the components of a two-choice conditional discrimination. First, the successive discrimination between the sample stimuli was established by programming a different schedule of reinforcement in the presence of each sample stimulus. Schedule performance was acquired and maintained by both subjects, but neither acquired arbitrary matching. To train the simultaneous discrimination between the comparison stimuli, 1 subject was then exposed to a series of simple discrimination reversals and subsequently failed to acquire arbitrary matching. Both subjects acquired arbitrary matching under a procedure that maintained both the sample and the comparison discrimination by first presenting entire sessions composed of one sample-comparison relation and then gradually reducing the number of consecutive trials with the same sample until sample presentation was randomized (schedule performance was maintained). Removal of the schedule requirement had no effect on arbitrary matching accuracy. Both subjects subsequently demonstrated control by relations symmetric to the trained relations.
