INTERSPERSED REQUESTS: A NONAVERSIVE PROCEDURE FOR REDUCING AGGRESSION AND SELF-INJURY DURING INSTRUCTION

Interspersed requests are simple commands, with a high likelihood of being followed correctly, that are interspersed among instructional trials to increase the probability that a learner will attempt to perform new or difficult tasks without engaging in aggression or self-injurious behavior. This report presents two assessments of the effect of interspersed requests on aggression and self-injury during instruction. The participants were individuals with severe mental retardation who used aggression and self-injury to avoid difficult instructional situations. Results from both studies indicate that interspersed requests were effective at increasing the responsiveness of the learners to instructions and reducing levels of aggression and self-injury.     

APPLICATION OF THE “GENERALIZATION MAP” TO A SELF-CONTROL INTERVENTION WITH SCHOOL-AGED CHILDREN

The assessment of generalization has become a priority of applied behavior analysis. This study provided a thorough assessment of the generality of a comprehensive self-control intervention. This intervention incorporated a number of self-management skills and was designed to increase the math performance of an underachieving student in a regular elementary school classroom. All possible classes of generalization as outlined by Drabman, Hammer, and Rosenbaum (1979) were assessed. An ABAB design with follow-up was used to determine the effectiveness of the intervention for the treated student's math performance in the school setting as well as the degree of generalization across the following untreated dimensions: behavior (disruptiveness); setting (home); subject (classmate); and time period (follow-up). The effective intervention produced: subject, behavior, subject-behavior, setting, subject-setting, behavior-setting, subject-behavior-setting, time, subject-time, setting-time, subject-setting-time, and subject-behavior-setting-time generalization. Generalization was not obtained for behavior-time, subject-behavior-time, and behavior-setting-time generalization. Features of this intervention which may have promoted generalization are discussed.     

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.     

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.     

Stimulus equivalence instruction of fraction-decimal relations

Stimulus control technology was applied to the instruction of fraction ratio (e.g., (1/5)) and decimal (e.g., 0.20) relations, with 7 students who demonstrated difficulty in fraction and decimal tasks. The students were trained to match pictorial representations of fractions (B comparison stimuli) to printed counterpart fraction ratios (A sample stimuli), and to match printed decimals (C comparison stimuli) to pictorial representations of counterpart quantities (B sample stimuli). Posttest performance by all participants indicated the emergence of equivalence relations between fractions represented as ratios, decimals, and pictures. Limited generalization of fraction-decimal relations was observed.     

EFFECTS OF SELF-INSTRUCTIONAL TRAINING ON SECOND- AND THIRD-GRADE HYPERACTIVE CHILDREN: A FAILURE TO REPUCATE

Bornstein and Quevillon (1976) demonstrated generalization from a 2-hour self-instructional training session to on-task behavior in the classroom with 4-year-old overactive children. In an attempt to replicate this work with older children, eight 7- and 8-year-old hyperactive children were assigned to either a self-instructional training group or an attention-practice control group. On-task behavior in the classroom and performance measures in reading and arithmetic were assessed. The level of difficulty of these tasks was varied. The results of Bornstein and Quevillon's (1976) study were not replicated, although the subsequent introduction of a token program significantly increased on-task behavior.     

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.     

INCREASING SPELLING ACHIEVEMENT: AN ANALYSIS OF TREATMENT PROCEDURES UTILIZING AN ALTERNATING TREATMENTS DESIGN

Two studies which examine the effectiveness of spelling remediation procedures are reported. In both studies, an alternating treatment design was employed. In the first study, positive practice overcorrection plus positive reinforcement was compared to positive practice alone and a no-remediation control condition. In the second study, positive practice plus positive reinforcement was compared to a traditional corrective procedure plus positive reinforcement and a traditional procedure when used alone. Results of both studies indicated that the combined positive practice plus positive reinforcement procedure was more efficient and that it was preferred by the children. Following brief training under this combined procedure, all children demonstrated 100% spelling accuracy.     

The significance and future of functional analysis methodologies

Iwata, Dorsey, Slifer, Bauman, and Richman (1982) presented the first comprehensive and standardized methodology for identifying operant functions of aberrant behavior. This essay discusses the significance functional analysis has had for applied behavior analysis. The methodology has lessened the field's reliance on default technologies and promoted analysis of environment-behavior interactions maintaining target responses as the basis for selecting treatments. It has also contributed to the integration of basic and applied research. Future directions for this research are suggested.     

SELF-RECORDING OF ATTENTION VERSUS PRODUCTIVITY

We investigated the relative effects of self-recording of attentive behavior and self-recording of academic productivity with 5 upper elementary-aged special education students in their special education classroom. Following baseline, both self-recording treatments were introduced according to a multielement design. After the multielement phase, we assessed the pupils' performance under a choice condition, faded the overt aspects of the treatment program according to a withdrawal design, and probed maintenance over 5 weeks. Results revealed that both treatments produced clear improvements in arithmetic productivity and attention to task, neither treatment was clearly and consistently superior to the other, pupils preferred the self-recording of attention treatment, the effects were maintained for all pupils, achievement test scores improved, and pupils generally recorded accurately.     

MODIFYING LETTER AND NUMBER REVERSALS IN ELEMENTARY SCHOOL CHILDREN1

Children from regular and special-education classes were exposed to tutoring procedures designed to modify letter and number reversals. In Experiment I, two students showed reversals during letter-naming (e.g., saying p for q) and two-digit number (e.g., writing 31 for 13) exercises. In Experiment II, one subject made two-digit reversals, while the other child reversed single-digit numbers (e.g., 9 written with circle on right side of stem). The subject in Experiment III emitted letter reversals under naming, dictation, and copying exercises. The child in Experiment IV showed written letter reversals on both sides of the “body midline” under dictation procedures. Basic treatment procedures during all experiments involved modelling of correct and incorrect symbol formation, and differential experimenter feedback following student responses. During Experiments I and II, subjects were praised for each correct response, and informed when a reversal occurred. Experiment III included a Modelling Only Phase before these feedback procedures. Besides praise, treatment conditions in Experiment IV consisted of additional feedback following correct responses (e.g., charting correct responses), and temporal delays imposed between dictated letters and student responses. Except for occasional letter-naming reversals of one subject (Experiment I), and letter dictation errors of another (Experiment IV), reversals were eliminated when all experiments terminated. The Modelling Only Phase in Experiment III also reduced reversals to a low level. These findings suggest that a variety of reversal problems may be effectively assessed and remediated via simple modelling and reinforcement procedures. In addition, postcheck observations indicated that the effects were enduring. The present procedures should be easily implemented by school personnel.     

Reaffirming The Importance Of ��Analysis�� In Applied Behavior Analysis: A Review Of A. C. Repp And R. H. Horner��s Edited Book, Functional Analysis Of Problem Behavior: From Effective Assessment To Effective Support.

In recent years, much has been written about the topics of functional assessment and functional analysis in applied settings. In their book, Functional Analysis of Problem Behavior: From Effective Assessment to Effective Support, Repp and Horner (1999) have compiled a series of essays from experts on the topic. In this article, we review their work and comment on each chapter's contribution to the relevant literature. We conclude that the book meets its primary goals of expanding our view of functional analysis as well as providing those new to the field with a stronger understanding of the topic. We do, however, note some concerns with inconsistent use of functional analysis terminology and a lack of practical guidance regarding its implementation in applied settings, but we believe these limitations are inherent in the empirical literature and are not unique to this book. Thus, we strongly endorse this book as “must reading” for behaviorally oriented researchers, students, and practitioners.     

Altering the timing of academic prompts to treat destructive behavior maintained by escape

Following a functional analysis showing that destructive behavior was reinforced by escape, we altered the aversiveness of task demands by interspersing easy and difficult tasks and by presenting a corrective prompt as an antecedent event the next time a previously failed item was presented; this procedure was compared with one in which the corrective prompt was provided as an immediate consequence. Results of a reversal design showed that the antecedent prompt acted as an establishing operation and reduced destructive behavior to zero.     

A Functional Analysis of Psychological Terms Redux

In his seminal paper, “An Operational Analysis of Psychological Terms,” Skinner (1945) offered the revolutionary suggestion that, rather than endlessly debating the meanings of psychological terms, psychologists should analyze the variables that control their occurrence as verbal behavior. Skinner''s suggestion reflected the essence of his 1957 book, Verbal Behavior, wherein he argued that the behaviors of which language is composed (i.e., speaking and listening) are controlled by variables found in the social environment (which he called the verbal community), and that analyzing those variables would lead to an understanding of the behaviors. Although Skinner formally introduced his radical approach to language in 1945, it has yet to be fully realized. The result is that psychologists, including behavior analysts, still debate the definitions of terms. In the present paper, I review Skinner''s functional approach to language and describe ways in which behavior analysts have already applied it to traditional psychological terms. I conclude by looking at other current terms in behavior analysis that engender some confusion and encourage behavior analysts to apply a functional analytic approach to their own verbal behavior.
