A PRELIMINARY EVALUATION OF EMPIRICALLY DERIVED CONSEQUENCES FOR THE TREATMENT OF PICA

Individualized treatment packages were developed for 3 children with high-rate severe pica using a discrimination training paradigm and a behavioral assessment-based procedure known as empirically derived consequences. Children received empirically derived reinforcers for eating under appropriate stimulus conditions (i.e., eating food only from a plate and placemat that served as a discriminative stimulus) and empirically derived punishers for attempts to engage in pica. This treatment package resulted in marked reductions in pica and an increase in appropriate eating for all 3 children in a “baited” analogue condition. In addition, low rates of pica were maintained for 9 months for all 3 children. These results suggest that treatment effectiveness may be enhanced when behavioral assessment data are used to identify potent consequences.     

REDUCTION OF SELF-INJURIOUS HAND MOUTHING USING RESPONSE BLOCKING

We evaluated a response-blocking procedure for reducing the self-injurious hand mouthing of 2 adults with profound disabilities. The procedure reduced mouthing in both cases. The results suggest research is warranted to delineate the behavioral process responsible for the effect of response blocking and to determine the procedure's long-term utility.     

Conditional discrimination in mentally retarded subjects: programming acquisition and learning set.

In Experiment 1, 3 subjects with retardation were exposed to two visual-visual arbitrary matching-to-sample problems each day. One conditional discrimination was presented under trial-and-error conditions, and the other was presented under a component training procedure. The latter began by establishing the comparison discrimination and its rapid reversal. The successive discrimination between the sample stimuli was established through differential naming. Then, sample naming was maintained in conditional discrimination sessions in which the same sample was presented in blocks of consecutive trials. Block size was decreased across sessions until sample presentation was randomized as in trial-and-error training (but with naming maintained). Two subjects initially learned only with component training. The performance of the 3rd subject was inconsistent across conditional discriminations. One of the successful subjects ultimately learned rapidly and consistently with trial-and-error procedures. Experiment 2 sought to demonstrate learning set in the other 2 subjects. Elements of the component training procedure were withdrawn over successive conditional discriminations. Ultimately, 1 subject nearly always learned under trial-and-error conditions, and the other learned under trial-and-error conditions combined with differential sample naming.     

A PERSONALIZED SYSTEM OF INSTRUCTION FOR TEACHING CHECKING ACCOUNT SKILLS TO ADULTS WITH MILD DISABILITIES

This study evaluated the efficacy of a personalized system of instruction to teach checking account skills to persons with mild disabilities. Using a self-paced manual, 8 participants in two groups were taught to write checks, complete deposit slips, and reconcile monthly bank statements. Four participants were assessed for generalization from the classroom to community sites and demonstrated nearly perfect performance. A multiple probe design showed that acquisition occurred sequentially for each skill only after training using the self-paced manual. Follow-up sessions demonstrated that participants maintained the checking account skills. The results provide evidence of the effectiveness and adaptability of a personalized system of instruction for teaching complex monetary skills to persons with mild disabilities.     

A COMPONENT ANALYSIS OF FUNCTIONAL COMMUNICATION TRAINING ACROSS THREE TOPOGRAPHIES OF SEVERE BEHAVIOR PROBLEMS

We evaluated the separate treatment components of a functional communication training program for 3 severely handicapped persons who each displayed different topographies of aberrant behavior. Following a functional analysis of maintaining conditions for inappropriate behavior (self-injury, stereotypy, aggression), each participant was trained to emit a communicative response that functioned to solicit reinforcement. For 2 participants, consequences (time-out or graduated guidance) for inappropriate behavior were also included. Treatment continued until the participants emitted the communicative response independently and no occurrences of inappropriate behavior were observed for at least two sessions. Following treatment, the separate contributions of the treatment components for communicative responding and for inappropriate behavior were evaluated with a reversal design. The results indicated that both sets of treatment components were necessary for maximal control over aberrant behavior. These results are discussed in relation to the efficiency, history, and control over reinforcement of both appropriate and inappropriate responses.     

BALANCING THE RIGHT TO HABILITATION WITH THE RIGHT TO PERSONAL LIBERTIES: THE RIGHTS OF PEOPLE WITH DEVELOPMENTAL DISABILITIES TO EAT TOO MANY DOUGHNUTS AND TAKE A NAP

In the pursuit of efficient habilitation, many service providers exercise a great deal of control over the lives of clients with developmental disabilities. For example, service providers often choose the client's habilitative goals, determine the daily schedule, and regulate access to preferred activities. This paper examines the advantages and disadvantages of allowing clients to exercise personal liberties, such as the right to choose and refuse daily activities. On one hand, poor choices on the part of the client could hinder habilitation. On the other hand, moral and legal issues arise when the client's right to choice is abridged. Recommendations are offered to protect both the right to habilitation and the freedom to choose.     

ASSESSMENT OF STIMULI CONTROLLING THE REQUESTS OF STUDENTS WITH SEVERE MENTAL RETARDATION DURING A SNACK ROUTINE

This study assessed stimuli controlling requests during a snack routine after extensive request training with a delayed prompt procedure. During training sessions, one of three three-item snack groups was presented to 3 subjects with severe mental retardation. Assessment sessions involved (a) training conditions (all items were visible), (b) presenting two of three items from a particular group, or (c) presenting no items. One subject requested food items when no food items were present, 2 frequently requested a missing item when the two other items were visible, and all subjects requested visible items. Procedures for assessing stimulus control, such as those described in the current paper, should lead to a better understanding of the variables controlling behaviors that initially appear perplexing and unpredictable.     

TEACHING ADULTS WITH SEVERE AND PROFOUND RETARDATION TO EXIT THEIR HOMES UPON HEARING THE FIRE ALARM

Prompting, modeling, and differential reinforcement with client-chosen rewards were used to teach 3 nonverbal people with severe to profound mental retardation to exit their group homes at the sound of the house fire alarm, using a multiple baseline design. All 3 participants learned to exit independently in less than 2 min in all experimenter-initiated surprise fire drills and in the majority of staff-initiated surprise fire drills. Each participant was also able to exit from five areas of the house from which teaching was not done.     

弱智儿童自发性话语中的情感韵律研究

本文用提取声学参数的方法,采用故事讲述任务对弱智儿童自发性话语中的情感韵律进行研究。通过与两组典型儿童-实际年龄匹配组和语言能力匹配组进行比较,探究了弱智儿童自发性话语中情感韵律的表达情况。结果发现：（1）弱智儿童的情感韵律存在一定程度的损伤,在音高范围和元音时长上均有表现;（2）弱智儿童的情感韵律独立于词汇和句法,具有模块性。     

Reflections on special-care babies and their early experience

In this paper the author presents some ideas about rapprochement and reciprocity, and considers them in relation to the experience of special-care babies and their mothers. Psychoanalytic infant-observation is discussed in the context of the relationship between psychoanalysis and developmental psychology and its value as a method of research is explored. Observational research has contributed to the understanding of early mother-infant relationships, and in particular has highlighted the importance of reciprocity and fit. The crucial importance of this in relation to premature babies' early relationships is illustrated by the presentation of extracts from the observations of three mother-child pairs during their stay in a special-care baby unit.
