Peer reinforcement control of classroom problem behavior

Peer and teacher interactions with five "disruptive" children were studied in an elementary school classroom. The intent of the study was to analyze experimentally peer reinforcement control of the disruptive children's problem behaviors. Social attention provided by all peers was found to be directed exclusively to the problem behaviors during baseline. Following baseline, several manipulations of selected peer social attention demonstrated the reinforcement function of this stimulus class.     

Home-based reinforcement and the modification of pre-delinquents' classroom behavior

In Exp. I, five pre-delinquents from Achievement Place attended a special summer school math class where study behavior and rule violations were measured daily for each boy. The boys were required to take a "report card" for the teacher to mark. The teacher simply marked yes or no whether a boy had "studied the whole period" and "obeyed the class rules." All yeses earned privileges in the home that day but a no lost all the privileges. Using a reversal design, it was shown that privileges dispensed remotely could significantly improve classroom performance. In Exp. II and III, home-based reinforcement was also shown to be effective in improving the study behavior of two youths in public school classrooms. In addition, data from Exp. III suggest that the daily feedback and reinforcement may be faded without much loss in study behavior. Home-based reinforcement was demonstrated to be a very effective and practical classroom behavior modification technique.     

A descriptive analysis of potential reinforcement contingencies in the preschool classroom

In recent years, functional analysis methods have been extended to classroom settings; however, research has not evaluated the extent to which consequences presented during functional analysis are associated with problem behavior under naturalistic classroom conditions. Therefore, the purpose of this study was to determine whether the social consequences commonly manipulated in functional analyses occur in typical preschool classrooms. A total of 14 children attending preschool programs participated in the study. Data were collected on the occurrence of antecedent events (e.g., presentation of tasks), child behaviors (e.g., aggression), and teacher responses (e.g., delivery of attention). The probability of various teacher responses given child behavior was then calculated and compared to the response-independent probabilities of teacher responses. Attention was found to be the most common classroom consequence (100% of children), followed by material presentation (79% of children), and escape from instructional tasks (33% of children). Comparisons of conditional and response-independent probabilities showed that the probability of teacher attention increased given the occurrence of problem behavior for all children, suggesting that a contingency existed between these two events. Results suggest that functional analyses that test the effects of attention, escape, and access to materials on problem behavior may be appropriate for preschool settings.     

The effect of vicarious reinforcement on attentive behavior in the classroom

The effect of social reinforcement delivered to target subjects on the attentive behavior of adjacent peers was examined in a classroom setting. In a combined reversal and multiple baseline design, two pairs of mentally retarded children were sequentially exposed to three reinforcement phases. After baseline rates of attentive behavior were obtained, praise was delivered to the target subject in each subject pair for attentive behavior. After a reversal phase, praise was delivered contingently to target subjects for inattentive behavior. In a final phase, contingent praise for attentive behavior was reinstated for the target subjects. Throughout the study, nontarget subjects received no direct reinforcers. The results indicated a vicarious reinforcement effect. Reinforcing attentive behavior of target subjects increased this behavior in adjacent peers. However, reinforcing inattentive behavior of target subjects also increased the attentive behavior of adjacent peers. The effects obtained through vicarious reinforcement were considered to reflect the discriminative stimulus properties of reinforcement, which may serve as a cue for the performance of nonreinforced peers.     

Decreasing classroom misbehavior through the use of DRL schedules of reinforcement

In three studies, reinforcing low rates of responding reduced inappropriate behaviors. In the first study, the talking-out behavior of one TMR student was reduced when the teacher allowed 5 min of free time for a talk-out rate less than 0.06 per minute. In a second study, the talking-out behavior of an entire TMR class was reduced when reinforcement was delivered for a response rate less than 0.10 per minute. In a third study, successively decreasing DRL limits were used to reduce off-task verbalizations of an entire high school business class. In each case, the DRL procedure proved manageable for the teacher and successful in reducing misbehavior.     

Instructing beginning teachers in reinforcement procedures which improve classroom control

Systematic reinforcement procedures were used to increase study behavior in the classrooms of three beginning teachers experiencing problems of classroom control. Classroom study rates were recorded during a baseline period. During subsequent experimental periods, the teachers changed one or more reinforcement contingencies (teacher attention, length of between-period break, a classroom game) to bring about increased study rates and concomitant reductions in disruptive behaviors. A brief reversal period, in which these contingencies were discontinued, again produced low rates of study. Reinstatement of the contingencies resulted once again in marked increases in study behaviors.     

Interdependent and independent group contingencies with immediate and delayed reinforcement for controlling classroom behavior

Group-oriented contingency systems have enjoyed widespread acceptability, use, and success in classroom settings. Despite their increased use, group contingency systems have at least two disadvantages. First, one or more students may spoil reinforcement for the rest of the class, and, second, the behavior of the entire class often deteriorates as a result of the loss of access to reinforcement. The present study investigated the use of an interdependent group contingency for on-task and disruptive behavior along with an independent group contingency for disruptive behavior to prevent children from spoiling group reinforcement. Immediate and delayed consequences were built into the program to circumvent behavioral deterioration. The results demonstrated that the combination of group contingency systems and immediate and delayed consequences were effective in reducing levels of off-task and disruptive behavior and in increasing on-task behavior. The findings were discussed in terms of the combination of treatment components, potential for generalization, the need for empirical research on social validity, and the practicality and effectiveness of this intervention package for psychologists in the schools.     

The teacher as observer and experimenter in the modification of disputing and talking-out behaviors

Disputing and talking-out behaviors of individual pupils and entire classroom groups in special education classes and regular classes from white middle-class areas and from all black poverty areas ranging from the first grade to junior high school were studied. The classroom teacher in each case acted as the experimenter and as an observer. Various means of recording behaviors were used and reliability of observation was checked by an outside observer, another teacher, a teacher-aide, a student, or by using a tape recorder. Observation sessions varied from 15 min to an entire school day. After baseline rates were obtained, extinction of inappropriate disputing or talking-out behaviors and reinforcement of appropriate behavior with teacher attention, praise and in some cases a desired classroom activity or a surprise at the end of the week brought a decrease in undesired verbalizations. A reversal of contingencies brought a return to high levels of inappropriate talking with a return to low levels when reinforcement for appropriate talking was reinstated. The experiments demonstrated that teachers in a variety of classroom settings could obtain reliable observational records and carry out experimental manipulations successfully using resources available in most schools.     

Preference for conditioned reinforcement.

Pigeons were presented with a concurrent-chains schedule in which both choice alternatives led to the same terminal-link stimulus, which was followed by food. Superimposed on the food-reinforced presentations of the terminal-link stimulus was a second schedule of presentations of the same stimulus that were followed by no food. The absolute number of these no-food stimulus presentations was held constant while their relative frequency assigned to one or the other choice alternative was systematically varied. Preference for a given choice alternative tracked the relative frequency of these stimulus presentations, thus demonstrating that they served as reinforcers. These results resolve conflicts in the literature regarding the effect of conditioned reinforcement on choice.     

Use of a lag differential reinforcement contingency to increase varied selections of classroom activities

The present study evaluated the effects of a lag differential reinforcement contingency on 2 students' activity selections using reversal designs. Results showed that the lag contingency was responsible for promoting increased novel selections, engagement in diverse activities, and greater progress with respect to programmed academic activities.     

Sexual reinforcement in the female rat.

Sexual reinforcement in the female rat was studied in a preparation that allowed continuous operant responding for access to a male rat leading to intromission. Experiment 1 used a high operant level nose-poke response to test the possible reinforcing effects of some components of access to a male. A simple tone stimulus used as a conditioned reinforcer and two odor stimuli, target male bedding and emulsified preputial gland, were tested. None of these contingent events altered responding above or below operant level. Access to the male, which was always accompanied by intromission, immediately increased response rate when it was made contingent upon the nose-poke response. Performance on fixed-ratio schedules was erratic, and response rate was low in comparison to typical food-reinforced responding. An interresponse-time analysis indicated, however, that some effect of the ratio contingency may have been present. In Experiment 2, several modifications of the procedure were tested with the objective of creating a more tractable preparation for behavior analysis. Response type and the hormone delivery method were changed, and 2 target males were used instead of 1. The latter tripled the average number of reinforcers earned in a single session. Differences between sexual and other reinforcers are discussed in terms of procedural, quantitative, and motivational aspects of the sexual reinforcement procedure.
