IMPROVING CLASSROOM BEHAVIOR IN MENTALLY RETARDED CHILDREN THROUGH CORRESPONDENCE TRAINING

Except for a few studies, most research investigating correspondence training procedures has been more analogue in nature. The purpose of the present set of studies was to examine whether a “say-do” correspondence training technique could be used with children in special education classes to improve classroom behavior. The specific behaviors targeted for change included: out-of-seat behavior (Experiment 1), sitting posture (Experiment 2), and on-task behavior (Experiment 3). The say-do procedure used in Experiment 1 resembled that of previous studies, whereas that in Experiment 2 was more elaborate in the specificity of verbal statements required from the children and the feedback given them. The training procedure in Experiment 3 used a format similar to the say-do approach, but stressed visual rather than verbal cuing because it was used with nonverbal children. All three studies used single-subject designs and examined maintenance and/or generalization questions. Experiments 2 and 3 also evaluated whether concomitant changes in performance on academic tasks occurred. The results of the three studies provide strong evidence that correspondence training can be effectively used with educationally handicapped children. Moreover, the successful modification of the “say-do” to a “show-do” procedure in Experiment 3 points out the flexibility of the correspondence training approach.     

Self-instruction: An analysis of the differential effects of instruction and reinforcement

This study investigated the impact of training 9 first- and second-grade children to use a full self-instructional regimen, and then differentially reinforced the use of self-instruction only, accuracy only, or both self-instruction and accuracy. Three comparison children received no training in self-instruction and were reinforced for accuracy only. Children improved dramatically in academic accuracy subsequent to self-instructional training, independent of the use of self-instruction and of the specific behavior consequated. Children who were reinforced for using self-instruction did use self-instruction, and those who were not, did not. Comparison group children showed little improvement until training in problem-solving strategies was given after 9 days of reinforcement for accuracy. Self-instructional training is discussed as one type of event that increases the likelihood of accurate performance. Its effectiveness may be explained in terms of a teaching strategy rather than in terms of modifying cognitive processes.     

A SELF-INSTRUCTIONAL PACKAGE FOR INCREASING ATTENDING BEHAVIOR IN EDUCABLE MENTALLY RETARDED CHILDREN

The purpose of this study was to develop a self-instructional package that would aid highly distractible retarded children in increasing their attending behavior in a training and two generalization (a one-to-one and a classroom) situations. Three untrained subjects were monitored for general comparison and social validation purposes. One of these control subjects was distractible and the other two (criterion comparison) were evaluated as not having attentional problems. A multiple baseline design was employed in which training was sequentially introduced across subjects. During training, the experimental subjects were taught through self-instruction to focus their attention and to cope with two tasks, math and printing. After learning the self-instructions the subjects were systematically and sequentially exposed to photo-slides of distracting situations, to audio-distractors composed of noisy lunchroom verbal peer interactions, and to in vivo distractors provided by kindergarten children playing with wooden blocks in the training setting. The entire training procedure was handled in a game-like context to maintain subject interest and to facilitate generalization. The results suggested that the training package produced direct and generalized changes in self-instructional behavior. In addition, a decrease in off-task behavior occurred during math, printing, and also during a phonics program in the one-to-one and classroom situations. However, reliable changes in academic task performance were not observed. Finally, no systematic changes on any of the dependent measures occurred for the three untrained subjects.     

TEACHING YOUTHS WITH AUTISM TO OFFER ASSISTANCE

Three adolescent boys with autism were taught to offer assistance to a person stating inability to complete a task. The study used a multiple baseline across the 3 youths and a multiple baseline across three tasks for each student. Both designs provided clear support for the ability of the youths to discriminate those settings in which offers of assistance were desired. All 3 participants showed relatively rapid acquisition of responding. Generalization was assessed to a new person in the training setting, to a familiar person in a new room at the center, to the mother in the youth's home, and to three novel tasks. Generalization to a new person in the familiar setting was most likely to occur, with very high levels of responding for all 3 youths. Generalization to the other conditions varied across youths, although all 3 boys showed some transfer of skills to all conditions.     

The functional role of preschoolers' verbalizations in the generalization of self-instructional training

We examined the functional role of verbalizations in the generalization of self-instructional training with preschoolers. Children learned to overtly self-instruct during classroom work periods prior to covert training. Data were collected on children's acquisition of verbal regulation during training and on overt use of self-instructions in the classroom generalization setting. Results of a multiple baseline design across subjects indicated that treatment effects were evident in the training setting but did not generalize to the classroom until children were emitting overt self-instructions in the classroom itself. The production of self-verbalizations in the generalization setting was related to changes in correct responding, on-task behavior, and efficiency in completing academic work.     

Self-instruction training following neurological injury

The teaching of cognitive strategies is a potentially effective intervention technique for some students with acquired neurological injuries; however, educators have only infrequently reported on the systematic application of cognitive strategies to the academic challenges of this population. This study represents such an attempt by investigating the effects of a self-instruction strategy on the academic performance of a student with acquired neurological damage. The intervention programme pertained to performing 2-digit by 1-digit multiplication problems and consisted of: (1) a six-step multiplication procedure; (2) self-instruction cues; and (3) procedural prompts. The intervention package resulted in improved performance on the multiplication task with levels being maintained despite fading of procedural prompts and self-instruction cues. Results are discussed in terms of implications for training and future research.     

SELF-INSTRUCTIONAL TRAINING TO INCREASE INDEPENDENT WORK PERFORMANCE IN PRESCHOOLERS

The generalized effects of self-instructional training on the classroom performance of three “impulsive” preschool children were investigated using a multiple-baseline design across subjects. Measures of child and teacher behavior in the classroom were obtained through direct observations during a daily independent work period. Self-instructional training followed Meichenbaum and Goodman's (1971) approach, except that training materials consisted of naturalistic task worksheets rather than psychometric test items and training sessions were of shorter duration. For all three children, self-instructional training resulted in increased levels of accuracy on worksheets in the classroom that were similar to those used in training. Results related to several supplementary measures were less clear; however, they suggested that rates of on-task behavior may also have improved, and that a mild classroom intervention further strengthened on-task rates and effected consistent work completion for all three children. The findings suggested that generalized increases in accuracy on classroom worksheets were related to the naturalistic format of the self-instructional training sessions. The level of teacher attention was controlled to rule out its effect on changes in child behavior.     

EVALUATION OF THE GENERALIZED EFFECTS OF A PEER-TRAINING PROCEDURE WITH MODERATELY RETARDED ADOLESCENTS

The use of peer-training procedures by moderately mentally retarded adolescents was evaluated in two experiments. In Experiment 1, 2 students received instruction on peer-training skills to teach a vocational task to 7 classmates. Following instruction, both peer trainers were successful in teaching their classmates to perform the target task and a second untrained (generalization) task. In Experiment 2, 1 peer trainer taught 3 peers to use picture prompts to complete one or two complex vocational tasks. Following instruction by the peer trainer, the trainees independently used novel pictures on novel tasks. The results of both experiments indicate that peer training with moderately handicapped students can be an effective instructional procedure, with generalization occurring for both the trainers (Experiment 1) and the trainees (Experiment 2).     

Performance among different types of myocontrolled tasks is not related

Studies on myocontrolled assistive technology (AT), such as myoelectric prostheses, as well as rehabilitation practice using myoelectric controlled interfaces, commonly assume the existence of a general myocontrol skill. This is the skill to control myosignals in such a way that they are employable in multiple tasks. If this skill exists, training any myocontrolled task using a certain set of muscles would improve the use of myocontrolled AT when the AT is controlled using these muscles. We examined whether a general myocontrol skill exists in myocontrolled tasks with and without a prosthesis. Unimpaired, right-handed adults used the sEMG of wrist flexors and extensors to perform several tasks in two experiments. In Experiment 1, twelve participants trained a myoelectric prosthesis-simulator task and a myocontrolled serious game for five consecutive days. Performance was compared between tasks and over the course of the training period. In Experiment 2, thirty-one participants performed five myocontrolled tasks consisting of two serious games, two prosthesis-simulator tasks and one digital signal matching task. All tasks were based on tasks currently used in clinical practice or research settings. Kendall rank correlation coefficients were computed to analyze correlations between the performance on different tasks. In Experiment 1 performance on the tasks showed no correlation for multiple outcome measures. Rankings within tasks did not change over the training period. In Experiment 2 performance did not correlate between any of the tasks. Since performance between different tasks did not correlate, results suggest that a general myocontrol skill does not exist and that each myocontrolled task requires a specific skill. Generalization of those findings to amputees using AT should be done with caution since in both experiments unimpaired participants were included. Moreover, training duration in Experiment 2 was short. Our findings indicate that training and assessment methods for myocontrolled AT use should focus on tasks frequently performed in daily life by the individual using the AT instead of merely focusing on training myosignals.     

Conversation skills training for socially isolated children

A social skills training program consisting of instructions, modeling, behavior rehearsal, performance feedback, and programmed generalization set was used to teach conversational behavior to four socially isolated children. Effects of training were assessed in a multiple-baseline analysis across behavior. Subjects were selected on the basis of peer sociometric ratings, a behavioral role-playing task, naturalistic observation, and teacher ratings. All subjects demonstrated noticeable improvement in the target behavior as well as in overall conversational ability. However, these gains were maintained unequally in the children at follow-up probe administrations (4-and 8-weeks). Generalization assessment revealed some transfer of treatment effects to the school setting for all children. Results are discussed in terms of the complexity of social isolation in children and factors which influenced generalizability of the treatment program.     

Efficacy of self-instructional training for reducing children''s anxiety in an evaluative situation

Fifty-six fourth-grade children were categorized as either high or low in trait anxiety and then assigned to a self-instruction treatment, minimal-treatment, or no-treatment control condition. At both pretest and posttest, the subjects recited a memorized poem while being videotaped with the expectation that they would be judged on their performance. State anxiety measures, a behavior rating of anxiety, a measure of performance accuracy and the time involved in reciting a poem were obtained at both pretest and posttest. Contrary to expectation, the self-instructional training resulted in subjects' exhibiting greater signs of behavioral anxiety, subjects' hurrying through the task (taking less time to recite the poem) and high trait-anxiety subjects' reporting more state anxiety while anticipating reciting the poem. Correlational analyses indicated that trait anxiety was significantly related to the measures of state anxiety and the behavior rating of anxiety but not to performance accuracy.     

An Evaluation of Preference for Mode of Instruction Following Variations in Response Effort

The current study evaluated preference for mode of instruction (i.e., visual or vocal) for four children diagnosed with a language-based learning disability. Each participant was an elementary student who was initially referred to a neuropsychology clinic specializing in learning disabilities. As a part of the evaluation, measures of each participant’s academic skills were collected. Following the diagnostic evaluation, each participant was referred to a behavioral psychologist to participate in this two-experiment study. In Experiment 1, preference for mode of instruction was evaluated within a concurrent schedules design across increasing task difficulty. In Experiment 2, changes in preference for mode of instruction following increases in task amount were evaluated via a progressive ratio arrangement within a concurrent schedules design. Results from both experiments showed that preference for mode of instruction can change under high-effort conditions (i.e., task difficulty and task amount).     

Cognitive self-instruction for the control of impulsive classroom behavior: Ensuring the treatment package

The practical utility of cognitive self-instruction training in facilitating the work habits and academic performance of impulsive first-graders was assessed in the context of the regular classroom. The training paradigm was modified and environmental conditions were arranged to facilitate the transfer of the cognitive self-instruction strategy to the classroom. Following training, there were no significant increases in on-task behavior or in academic performance within the context of a group design. On the basis of this and other studies, a drastic revision of the cognitive self-instruction paradigm seems indicated. Not only must training become broader based, but models must be developed that take into account the requisite cognitive processes for task completion as well as the cognitive abilities of the youngsters to whom training is addressed. In general, the incorporation of information from the developmental and cognitive process literature would appear to facilitate the development of more effective training models.     

EFFECTS OF PICTURE PROMPTS ON THE ACQUISITION OF COMPLEX VOCATIONAL TASKS BY MENTALLY RETARDED ADOLESCENTS

The effects of using picture prompts on the acquisition, generalization, and maintenance of complex vocational tasks were evaluated within a multiple baseline design across subjects and tasks. Five moderately and severely mentally retarded adolescents were first trained to use picture prompts to guide their performance on one or more complex tasks. Following training, posttesting with and without the picture prompts was conducted to evaluate the effects of training and to determine maintenance effects over a 2- to 4-week interval. Generalization of performance across tasks was assessed with three of the students who were provided novel tasks (with and without picture prompts) without training. Results indicated that picture prompts can be successfully used to promote both acquisition and generalization of performance, and that subsequent training time on a novel task was reduced when the use of picture prompts had been previously trained.     

Five-year-old children's difficulty with false belief when the sought entity is a person

A total of 153 children (excluding those who erred on control questions), mainly 5 and 7 years of age, participated in two experiments that involved tests of false belief. In the task, the sought entity was first at Location 1 and then, unknown to the searching protagonist, it moved to Location 2. In Experiment 1, performance was well below ceiling in 5-year-olds when the sought entity was a person, and this contrasted with a task in which the sought entity was a physical object. Performance was especially inaccurate when the sought person moved of his or her own volition rather than when the sought person was requested to move by a third party. Interestingly, 5-year-olds were more likely to nominate Location 1 when asked where the searching protagonist would look first than when asked what he or she would do next. In Experiment 2, however, 5-year-olds also tended to nominate Location 1 following a question that included the word "first" even in a test of true belief--a patently incorrect response. Altogether, the results suggest that 5-year-old children have considerable difficulty with a test of false belief when the sought entity is a person acting under his or her own volition. This suggests that 5-year-olds' handle on states of belief is surprisingly fragile in this kind of task.     

STIMULUS CHARACTERISTICS WITHIN DIRECTIVES: EFFECTS ON ACCURACY OF TASK COMPLETION

Three experiments were conducted in an outpatient setting with young children who had been referred for treatment of noncompliant behavior and who had coexisting receptive language or receptive vocabulary difficulties. Experiment 1 studied differential responding of the participants to a brief hierarchical directive analysis (least‐to‐most complex stimulus prompts) to identify directives that functioned as discriminative stimuli for accurate responding. Experiment 1 identified distinct patterns of accurate responding relative to manipulation of directive stimulus characteristics. Experiment 2 demonstrated that directives identified as effective or ineffective in obtaining stimulus control of accurate responding during Experiment 1 continued to control accurate responding across play activities and academic tasks. Experiment 3 probed effects of the interaction between the type of directive (effective vs. ineffective) and the reinforcement contingency (differential reinforcement for attempts vs. differential reinforcement for accurate responses) on accurate task completion and disruptive behavior. Results suggested that behavioral escalation from inaccurate responding to disruptive behavior occurred only when ineffective directives were combined with differential reinforcement for accurate task completion. The overall results are discussed in terms of developing a methodology for identifying stimulus characteristics of directives that affect accurate responding.     

Promoting parent use of empirically supported reading interventions: two experimental investigations of child outcomes

Two experimental investigations of the effects of parent delivered reading interventions were conducted. Tutoring packages consisting of empirically supported intervention components were delivered by parents for at least several weeks after initial parent training. Both experiments used single‐case experimental designs and measured participants' oral reading fluency in passages. Experiment 1 used a multiple‐probe design across tasks (passages) to evaluate tutoring effects for two students with learning disabilities. Results indicate that both students increased their reading fluency and maintained those increases over time. Experiment 2 used a brief experimental analysis that included both experimenter and parent delivered instructional trials to validate the treatment package. Next, the treatment package was evaluated using an alternating treatments design. Results were uniformly positive. An interesting but not surprising correlation was also found between treatment integrity and student outcomes. Results are discussed in terms of the framework and skills that behavior analysts have for working with parents and schools to improve their children's academic responding.

DEVELOPMENT AND EVALUATION OF AN INFANT-CARE TRAINING PROGRAM WITH FIRST-TIME FATHERS

We evaluated the effectiveness of a multicomponent package in training infant-care skills to first-time fathers. After developing and socially validating a set of infant-care skills, we assessed the effects of training in a hospital-based program with expectant fathers (Experiment 1) and in a home-based program with fathers having varied degrees of experience with their infants (Experiment 2). In both experiments, a multiple probe design demonstrated that the training package was responsible for producing criterion performance by the expectant and first-time fathers. A 1-month generalization probe in Experiment 1 showed that the effects transferred across training conditions (training doll to human infant) and settings (hospital to home). An increase in the number of infant-stimulation activities performed by fathers was also observed in both experiments.     

Generalized oddity performance in preschool children: a bimodal training procedure

Oddity performance requires relational discriminative responding, which typically is difficult to establish in children with MAs below five. In Experiment 1, a combination intrasubject reversal and multiple baseline across subjects design was used to establish the internal validity of a bimodal intervention in establishing generalized oddity performance. Six of seven children demonstrated oddity responding when presented with stimuli that instantiated the oddity relation in the visual and auditory modalities simultaneously. Oddity performance was evaluated with both reversal assessments and assessments with new sets of stimuli. The newly acquired oddity performance was durable; the six children continued to respond discriminatively when returned to a visual-only task on which they previously had been unsuccessful. Utilizing a reversal assessment more stringent than that of Experiment 1, Experiment 2 replicated this effect. The present studies are the first to demonstrate the utility of bimodal training in establishing oddity performance. The bimodal procedure is discussed with respect to the theoretical positions of Gibson, Dinsmoor, and Dixon.     

The development of prospective memory in young schoolchildren: The impact of ongoing task absorption,cue salience,and cue centrality

This study presents evidence that 9- and 10-year-old children outperform 6- and 7-year-old children on a measure of event-based prospective memory and that retrieval-based factors systematically influence performance and age differences. All experiments revealed significant age effects in prospective memory even after controlling for ongoing task performance. In addition, the provision of a less absorbing ongoing task (Experiment 1), higher cue salience (Experiment 2), and cues appearing in the center of attention (Experiment 3) were each associated with better performance. Of particular developmental importance was an age by cue centrality (in or outside of the center of attention) interaction that emerged in Experiment 3. Thus, age effects were restricted to prospective memory cues appearing outside of the center of attention, suggesting that the development of prospective memory across early school years may be modulated by whether a cue requires overt monitoring beyond the immediate attentional context. Because whether a cue is in or outside of the center of attention might determine the amount of executive control needed in a prospective memory task, findings suggest that developing executive control resources may drive prospective memory development across primary school age.
