INDIRECT FACILITATION OF ON-TASK BEHAVIOR PRODUCED BY CONTINGENT FREE-TIME FOR ACADEMIC PRODUCTIVITY1

This study investigated the relationship between on-task behavior and the academic performance of three low achieving and disruptive children in an elementary school special-education class. A number of researchers have postulated that the direct elimination of off-task or disruptive behavior is a necessary prior requirement when increases in academic performance are sought in special-education classrooms composed of low achievers with below-average socioeconomic environments. The present research program investigated this issue and measured the incidence of on-task behavior and its relationship to changes in the performance of a variety of academic tasks brought about by the opportunity to engage in daily free-time activities. Three children from a class of eight “educably mentally handicapped” students were chosen as target subjects, as their repertoires seemed to be especially defective. These children were observed by the first author for 90-minute sessions three days a week, and data regarding on-task behavior were obtained by the use of an interval recording technique. In conjunction with the teacher, the first author also monitored the academic performance of the children in six structured activities—answer completion from boardwork instructions, task completion from handout assignments, comprehension of reading assignments and vocabulary recognition, accuracy of direction-following to audiotaped instructions, quality of copied handwriting, and the matching of appropriate phonetic sounds to pictured objects and situations. Following baseline sessions during which both on-task and academic performance was measured, several experimental sessions were conducted during which free-time was given noncontingently. During these sessions, no reliable changes in student performance were observed. Subsequently, the teacher and experimenters defined a specified percentage of correct completion of each of the six categories of skill performance as necessary for the achievement of the free-time reinforcer, during each experimental session. As a result, both the academic productivity and the on-task measures of behavior were observed to increase, even though reinforcement was not directly contingent upon on-task behavior. The subsequent reinstitution of noncontingent free-time was followed by lower rates of both output and on-task behavior. The final reintroduction of contingent free-time for academic productivity again produced substantial increases in both work accomplished correctly and on-task behavior. Corresponding increases in productivity were noted for most nontarget children as well. While the present investigation has shown a high correspondence between productivity and on-task behavior, we must keep in mind that on-task behavior can be defined in many different ways. It remains possible that differences in the degree of correlation between outcome measures and the topography of “work” activity may relate to the degree to which the specific on-task behaviors measured are actually required for the outcome behavior. The failure of many researchers to identify a direct relationship between “appearances” and output may be inherently a measurement problem.     

ELIMINATING DISCIPLINE PROBLEMS BY STRENGTHENING ACADEMIC PERFORMANCE1

Behavior modification procedures have typically been used to eliminate discipline problems in the classroom through reinforcement of nondisruptive behavior. This report demonstrates an alternative approach whereby discipline problems are eliminated by reinforcing relevant academic skills. Five fifth-grade boys, identified by their teacher as discipline problems, were observed. The teacher conducted 15-min performance sessions in her reading class during which written academic performance and disruptive behavior were recorded. These measures indicated that the boys' average level of disruption was 34%, while their reading performance was below 50%. When systematic token reinforcement was applied to reading performance only, the rate of disruption fell drastically, and reading performance increased. When the reinforcement procedure was withdrawn, disruption again rose, and reading performance declined. The reinstatement of reinforcement doubled reading performance and eliminated disruption.     

Using response cards to increase student participation in an elementary classroom

The use of response cards during large-group social studies instruction was evaluated in a fourth-grade classroom. The experiment consisted of two conditions, hand raising and write-on response cards, alternated in an ABAB design. During baseline, the teacher called upon 1 student who had raised his or her hand in response to the teacher's question. During the response-card condition, each student in the class was provided with a white laminated board on which to write one- or two-word answers in response to each question asked by the teacher. Rate of active student response during instruction was much higher with response cards than with hand raising. Most students scored higher on daily quizzes following sessions in which response cards were used than they did on quizzes that followed hand-raising sessions. Response cards were preferred over hand raising by 19 of the 20 students in the class.     

THE USE OF IMPOSED AND SELF-SELECTED TRAINING PACKAGES TO ESTABLISH CLASSROOM TEACHING SKILLS1

Although much is known about techniques for teaching elementary pupils in the classroom, no procedures have been consistently effective in training teachers to use these techniques. In the present study, six teacher trainees were observed individually and trained sequentially to use a variety of teaching skills: praise for academic responses, praise for appropriate classroom behavior, correction procedures for incorrect academic responses, and token fines. These skills were examined under four conditions: (1) baseline sessions were taught by the trainees before any instructions on the use of the teaching skills. (2) Instruction sessions were taught by the trainees after they were given instructions describing the use of several teaching skills. (3) During each Imposed-Package session, the trainees received modelling, verbal feedback, graphic feedback, and grade and quiz contingencies on their use of a particular teaching skill. (4) During each Self-Selected Package session, a grade contingency was in effect with the trainees choosing the components (modelling, verbal feedback, graphic feedback, quiz contingency) they wanted included in their training package for a particular skill. The effects of instructions were quite varied. Large increases on three of the four skills occurred with one trainee; almost no changes occurred with another trainee; and changes with the remaining four trainees fell within these extremes. The Imposed and Self-Selected Packages reliably increased the use of teaching skills, including those skills for which instructions had not been effective. The Self-Selected Package was considered to be as effective as the Imposed Package, since the time required for training a teaching skill varied from two to nine sessions with both packages. Under the Self-Selected Package, the trainees chose from modelling, verbal feedback, and graphic feedback, but none chose the quiz contingency. Questionnaire data collected after training showed that all six trainees preferred the Self-Selected Package to the Imposed Package. The effectiveness of the Self-Selected Package, together with the trainees' preference for it, suggests that it may be desirable for teacher training programs to specify the teaching skills, arrange a contingency for performance, and allow trainees to choose which additional components are to be used in each training session.     

Classroom treatment of autistic children: II. individualized instruction in a group

This study was designed to assess the feasibility of providing individualized instruction in a classroom of autistic children. In particular, we investigated whether students' unsupervised responding was a variable which would influence the effectiveness of individualized instruction procedures. Initially, one teacher attempted to teach different academic behavior to four autistic children simultaneously. During these sessions the teacher rotated from child to child, providing individualized instructions and reinforcers to each. We found, however, that each child stopped responding whenever the teacher rotated to a different child and, further, no academic progress occurred for any of the children during these sessions. In a multiple baseline design, treatment procedures were then introduced (prompt fading, chaining, and programmed instructional materials) to teach each student to continue working for an extended period of time after each instruction from the teacher. After treatment, sessions of individualized instruction in a group were reintroduced for each child. The results showed that unsupervised responding was an important variable influencing the effectiveness of individualized instruction. Specifically, the data show that (1) unsupervised responding, acquired during treatment, generalized to the group setting; (2) after treatment, each child began to make progress on his assigned tasks; and (3) programming instructional materials in small steps appeared to be necessary in order to ensure the maintenance of unsupervised responding across changes in instructional materials. By the end of this study it was possible for one teacher to simultaneously teach four autistic children — with each child learning at his own rate, on his own task, with minimal supervision from the teacher. It is suggested that the generalizability of these results, to other settings where continuous supervision is difficult, may be an important concern of future research.     

STIMULUS (INSTRUCTIONAL) FADING DURING EXTINCTION OF SELF-INJURIOUS ESCAPE BEHAVIOR

Three individuals with developmental disabilities were exposed to a series of assessment conditions to identify the source of reinforcement for their self-injurious behavior. In each case, self-injury occurred most often in instructional (demand) situations containing a brief time-out from the task contingent on self-injury, indicating that the behavior was an escape response (i.e., maintained by negative reinforcement). Treatment was implemented in a multiple baseline across subjects design and consisted of extinction (prevention of escape) plus instructional fading (initial elimination of instructions followed by their gradual reintroduction). Results showed that the combined treatment produced immediate and large reductions in self-injury that were maintained as the frequency of instructions was increased across sessions to match the original baseline rate of presentation. Results of a component analysis conducted with 1 subject suggested that stimulus fading accelerated the behavior-reducing effects of extinction.     

The effect of self-recording on the classroom behavior of two eighth-grade students

The effects of self-recording on classroom behavior of two junior high school students was investigated. In the first experiment, study behavior of an eighth-grade girl in history class was recorded. Following baseline observations her counselor provided slips for the girl to record whether or not she studied in class. This resulted in an increase in study. When slips were withdrawn, study decreased and then increased once self-recording was reinstated. After teacher praise for study was increased, self-recording was discontinued without significant losses in study behavior. In the final phase, increased praise was also withdrawn and study remained at a high level. In the second experiment, the number of talk outs emitted by an eighth-grade boy were recorded during math period. Following baseline, slips for recording talk outs were issued for the first half of the period, for the second half, and then for the entire period. Talk outs decreased when self-recording was in effect and increased again when self-recording was discontinued. When self-recording was reinstituted in the final phase there was a slight, though not significant decrease in talking out when compared to the baseline condition.     

A Review of: “Kennedy-Moore,E., & Lowenthal,M. S. (2011). Smart Parenting for Smart Kids: Nurturing Your Child's True Potential.”

Behavioral procedures aimed at decreasing disruptiveness through increasing self-evaluative skills and programming generalization in a class of disruptive retarded children were examined. Phases of the study included: (a) baseline; (b) systematic feedback; (c) a token economy; (d) matching of teacher's ratings by students; (e) four fading phases during which progressively fewer students were required to match the teacher; (f) self-evaluation during which each student received the amount of points self-allotted regardless of teacher's ratings; (g) doubling of point costs of back-up reinforcers ("Inflation"); (h) complete removal of back-up reinforcers ("Points Only"); and (i) return to baseline conditions. The class was observed 5 days per week dueing a morning experimental period and several times per week in the afternoon as a measure of generalization. Additional measures of generalization included days when the token program was not in effect ("Off Days") and when the class was taught by a substitute teacher. Behavior was recorded according to an interval sampling observational code. The results showed that systematic feedback was effective in significantly reducing disruptiveness with even greater reductions resulting from the token program and the subsequent matching and fading phases. Decreased levels of disruptiveness were maintained throughout self-evaluation and the phases which followed. Decreased levels of disruption also generalized to afternoon sessions, to days when the experimental procedures were not in effect, and to self-evaluate, the class initially matched the teacher's ratings with about 50% accuracy. This gradually increased to consistently above 90% during the latter phases. The study demonstrated that retarded children can learn to accurately observe and veridically evaluate their own behavior, and that this has beneficial effects in terms of decreased disruptiveness.     

Production and elimination of disruptive classroom behavior by systematically varying teacher's behavior

The effects of teacher behaviors on the classroom behaviors of children were investigated by systematically varying approving (praise, smiles, contacts, etc.) and disapproving (verbal reprimands, physical restraint, etc.) classes of teacher behavior. Measures were taken on both teacher and child behaviors. Each day a sample of 10 children was observed. The subject pool was a class of 28 well-behaved children in a middle-primary public school class. The results demonstrated that approving teacher responses served a positive reinforcing function in maintaining appropriate classroom behaviors. Disruptive behaviors increased each time approving teacher behavior was withdrawn. When the teacher's disapproving behaviors were tripled, increases appeared most markedly in the gross motor and noise-making categories of disruptive behavior. The findings emphasize again the important role of the teacher in producing, maintaining, and eliminating disruptive as well as pro-social classroom behavior.     

Differential effects of token reinforcement on instruction-following behavior in retarded students instructed as a group

This study was addressed to the problem of applying behavior modification techniques on a group basis to a class of retarded students with "attentional deficits". Seven boys, age 8 to 15 yr, characterized as showing severe "attentional" problems or disruptive behavior in their respective classrooms, participated daily for 30-min sessions in a special class over a 1.5-month period. In each session, verbal instructions were given to the class as a whole. In control sessions, each appropriate instruction-following response by a child produced praise for that child. In experimental sessions, appropriate responses also produced tokens exchangeable for tangible reinforcers after the session. Token reinforcement differentially maintained instruction-following behavior in four children while one responded appropriately to most instructions and a second improved continuously during the study. While the data suggest that the present approach can be successfully applied to the alteration of instruction-following behavior in retarded children, its major contribution may be that of providing objective quantitative information about such behavior.     

Cocaine's effects on food-reinforced pecking in pigeons depend on food-deprivation level.

Four pigeons deprived to 80% of their laboratory free-feeding weights pecked keys under a multiple fixed-ratio 30 fixed-interval 5-min schedule of food presentation. Components alternated strictly with 15-s timeouts separating them; each was presented six times. When rates of pecking were stable, 2 pigeons' weights were reduced to 70%, and the other 2 pigeons' weights were increased to 82.5% to 85% of free-feeding levels. Cocaine (1.0, 3.0, 5.6, and 10.0 mg/kg and saline) was administered 5 min prior to sessions. When each dose had been tested twice, pigeons' weights were adjusted to the level that they had not yet experienced, and cocaine was tested again. Cocaine reduced response rates in a dose-dependent manner under the fixed-ratio schedule and under the fixed-interval schedule at high doses, and increased rates under the fixed-interval schedule at low low doses. Reductions in pecking rates occurred at lower doses under both schedules in 3 of 4 pigeons when they were less food deprived compared to when they were more food deprived. Low doses of cocaine increased low baseline rates of pecking in the initial portions of the fixed-interval schedules by a greater magnitude when pigeons were more food deprived. Thus, food-deprivation levels altered both the rate-decreasing and rate-increasing effects of cocaine. The implications of these results for the mechanisms by which food deprivation increases cocaine self-administration and for the dependence of cocaine's effects on the baseline strength of operant behavior are discussed.     

EFFECTS OF COOPERATIVE LEARNING GROUPS DURING SOCIAL STUDIES FOR STUDENTS WITH AUTISM AND FOURTH-GRADE PEERS

We investigated the use of cooperative learning groups as an instructional strategy for integrating 2 students with autism into a fourth-grade social studies class. Baseline consisted of 40 min of teacher-led sessions including lecture, questions and discussion with students, and the use of maps. The intervention condition consisted of 10 min of teacher introduction of new material, followed by cooperative learning groups that included tutoring on key words and facts, a team activity, and a whole class wrap-up and review. An ABAB design showed increases for target students and peers for the number of items gained on weekly pretests and posttests, the percentage of academic engagement during sessions, and durations of student interaction during the intervention.     

Altering student responses through changes in teacher verbal behavior

Two experiments were conducted in a junior-high special-education class of eight pupils in an inner-city school. In the first experiment, the teacher doubled the number of words used by the pupils in answering questions by altering the type of questions asked. In the second experiment, the number of words used by students and the percentage of answers given in complete sentences, increased from less than 5% to approximately 90% when the teacher instructed the pupils to answer in complete sentences and asked another pupil to answer using a sentence if the first one did not do so. In both experiments, a brief return to baseline conditions brought a return to low levels of verbal responding. An analysis of which pupils were called on by the teacher, teacher praise, and in the second experiment the types of questions asked, indicated that these variables were not responsible for the increases in verbal responding.     

Behavior Disordered Children's Social Skills:

Four behaviorally disordered boys from an elementary school special education classroom received social skills training. They were selected on the basis of high negative nominations on the Class Pay sociometric measure. Training was designed to increase the rate at which the boys emitted prosocial behaviors toward their peers. Verbal instructions, modeling, role-play, and feedback were used to coach positive social behaviors in eight individual sessions with each boy. In a multiple baseline design across subjects, each of the target children showed an increase in positive behavior concurrent with training. A decrease in the occurrence of positive behavior followed termination of training, however, resulting in a final level of positive behavior intermediate between baseline and training levels. The expected increases in positive responses by peers did not occur, and the measure of sociometric status was not consistently sensitive to the observed behavioral change. Unique problems of social skills training in the special education classroom are discussed.     

DEVELOPING GENERALIZED BEHAVIOR-MODIFICATION SKILLS IN HIGH-SCHOOL STUDENTS WORKING WITH RETARDED CHILDREN1

Seven high-school trainees each conducted training sessions with two profoundly retarded children. Each trainee was asked to teach one child to follow the instruction “Bring ball” and the other child to follow the instructions “Sit down” and “Come here”. During baseline sessions, before the trainees had been instructed in behavior-modification techniques, no trainee successfully taught either child to follow the instructions. After differing numbers of baseline sessions, trainees were exposed to training procedures designed to teach them to teach one child to follow the instruction “Bring ball”. The training procedures consisted of videotaped modelling, rehearsal, and corrective feedback and praise. Following the training procedures, four of the seven trainees successfully taught their child to follow the instruction “Bring ball”. Further, all trainees were able to teach their other children to follow the instructions “Sit down” and “Come here”, even though they had received no modelling, rehearsal, or feedback on how to teach the children to follow these instructions. The ability of the trainees to teach new behaviors to different children indicates the development of generalized skills in behavior modification.     

USING HIGH-PROBABILITY INSTRUCTION SEQUENCES WITH FADING TO INCREASE STUDENT COMPLIANCE DURING TRANSITIONS

Making efficient transitions from one instructional activity to another has been shown to increase academic learning time and therefore student achievement. Because compliance with teacher instructions is a prerequisite for efficient transitions, we sought to determine if high-probability (high-p) instruction sequences issued by a classroom teacher would increase student compliance and decrease latency to comply during transitions. Three children in a regular second-grade classroom participated. Each day at the beginning of morning calendar time, the teacher issued five instructions to the class as a group while compliance data were recorded for the 3 target students. Following baseline, a multielement design was used to examine the effects of the high-p instruction sequence. We then systematically faded the number of instructions included in the high-p sequence as a means of transferring stimulus control to low-probability instructions. The procedure was effective for 2 of the 3 participants, and the results were maintained at 2-and 3-week follow-up. The implications of these findings for group applications of the high-p instruction sequence in regular education classrooms are discussed.     

REEMERGENCE AND EXTINCTION OF SELF-INJURIOUS ESCAPE BEHAVIOR DURING STIMULUS (INSTRUCTIONAL) FADING

Based on results of a functional analysis indicating that the self-injurious behavior (SIB) of 3 individuals was maintained by negative reinforcement (escape from instructional situations), the effects of stimulus (instructional) fading were evaluated in a multiple baseline design across subjects. The rate of instructions was reduced to zero at the beginning of treatment and was gradually increased (faded in) across sessions as long as SIB remained low. However, if SIB remained high for 10 consecutive sessions, extinction was implemented until SIB decreased, at which point extinction was withdrawn and fading was resumed. Treatment was completed when the rate of instructions was the same as in baseline (two per minute), and SIB remained below 0.5 responses per minute for two consecutive sessions. Results showed that instructional fading (without extinction) virtually eliminated SIB initially, but these effects were not maintained. All 3 subjects required multiple exposures to extinction and over 150 treatment sessions in order to meet the end-of-treatment criteria. Advantages and limitations of fading procedures without an extinction component, as well as extensions of both interventions to other clinical problems, are discussed.     

The ecobehavioral relationship between teachers' and disabled preschoolers' behaviors before and after supervisor training

A previous study (Hundert & Hopkins, 1992) demonstrated the functional relationship between preschool supervisor training and increased child and teacher behaviors. The present study describes a ecobehavioral analysis to suggest how the intervention worked. Following a baseline phase, three preschool supervisors were trained in a collaborative team approach where classroom and resource teachers jointly developed strategies to promote peer interaction of preschoolers with disabilities in three integrated classes. The results indicated that after the intervention: (a) the frequency of children's interactive play doubled during both training and generalization sessions; (b) covariations of peer interaction and teacher behaviors shifted from being related to the presence of a resource teacher in the class, to classroom teacher focus on groups that included a child with disabilities; and, (c) these shifts in child-teacher relationships were not clearly associated with changes in the frequency of teacher behaviors. The contribution of an ecobehavioral analysis to the understanding of complex environment-behavior relationships before and after an intervention is discussed.     

Utilizing in-vivo feedback for caregiver training of pediatric feeding protocols

Researchers have used multicomponent behavioral skills training packages including written and verbal instructions, modeling, rehearsal, and feedback when teaching caregivers to implement pediatric feeding treatment protocols (e.g., Anderson & McMillan, 2001; Seiverling et al., 2012). Some investigators have shown that fewer behavioral skills training components may be necessary for effective training (e.g., Mueller et al., 2003; Pangborn et al., 2013). We examined the use of in-vivo feedback following written instructions to train caregivers to implement pediatric feeding treatment protocols using a multiple baseline design across 3 caregiver dyads. Correct implementation of the feeding treatment procedures was low during baseline (written instructions only), increased with only the addition of in-vivo feedback, and remained high during follow-up sessions for all caregivers. Results are discussed in terms of clinical implications and caregiver satisfaction.
