Suppression of Chronic High Frequency Spitting in a Multiply Handicapped and Mentally Retarded Adolescent

Excessive drooling and spitting are maladaptive behaviors often encountered among severely developmentally delayed children. In the present study a blind, deaf and retarded adolescent exhibited an extremely high rate of spitting which had resisted numerous classroom intervention efforts by teachers using punishment techniques. His recalcitrant spitting was eliminated with a behavioral intervention consisting of positive reinforcement for not spitting and facial screening for spitting. Experimental control was demonstrated using a multiple baseline across situations and within subject reversal design. The treatment package successfully eliminated the child's chronic spitting. Teacher reports one year later indicated the results maintained across time and spitting was no longer a problem. Social and academic implications of modifying such behaviors are discussed.     

Use of delayed feedback and reinforcement for reducing inappropriate behaviors with chronically institutionalized mental clients

This study investigated the efficacy of: (a) delayed feedback; (b) delayed feedback and social reinforcement; or (c) delayed feedback, social reinforcement, and tangible reinforcement for reducing the rate of bizarre motoric behaviors for 2 female and 1 male chronically institutionalized mental clients. These treatments were consecutively employed with each subject, utilizing a multiple baseline across subjects experimental design. Results indicated that these subjects were able to retain and understand the feedback on both their problem and alternative behaviors but that reductions in the inappropriate motoric behaviors resulted only when tangible reinforcers were included in the treatment. Implications for further investigations and for the utility and efficiency of delayed feedback and reinforcement with chronically institutionalized adults are discussed.     

Staff Management By Behavioral Contracting

Employee performance has been shown to be improved by reinforcement procedures that are determined by the supervisor. The present study used behavioral contracting between an employee and her supervisor to structure their discussion in arriving at mutually acceptable performance standards and reinforcers. A multiple baseline design across responses was used with an employee who conducted training sessions with persons who are mentally retarded in a large institution. The results showed an improvement of the specific employee behaviors for which behavioral contracting was arranged for the duration of the contracted reinforcement. Behavioral contracting may be useful as a structured method of achieving employee-supervisor agreements in employee motivation programs.     

Neural network principles for theoretical psychology

Neural networks are an increasingly important tool for the mechanistic understanding of psychological phenomena. Three commonly used principles in neural-network design (associative learning, competition, and opponent processing) are outlined here, and two examples of their use in behavior-modeling architectures are discussed. One example relates to an instance of reinforcement learning; that is, of an organism controlling its environment to maximize positive reinforcement or to minimize negative reinforcement. The other example relates to some characteristic deviations from reinforcement learning that occur in people or monkeys with frontal-lobe damage.     

Relationship between parental discipline and children's ability to cope with stress

A questionnaire was developed to assess the use of disciplinary methods by parents regarding their children's approach to fearful situations. The predictive validity of this tool was evaluated by correlational analyses with the assessment of fear (behavioral, subjective, and physiological) in their children during hospitalizations for surgery. The results confirmed the usefulness of the questionnaire. Parents who reported use of positive reinforcement, modeling, and persuasion as ways of encouraging the child to deal with fearful situations had children who were low in anxiety during the actual stressful life experience. The reported use of punishment, force, or reinforcement of dependency was correlated with higher anxiety. Differences in the use of these methods by mothers and fathers are reported. The reliability of the questionnaire and its relationship to social desirability and the sex of the child are discussed.     

TRAINING PREDELINQUENT YOUTHS AND THEIR PARENTS TO NEGOTIATE CONFLICT SITUATIONS1

In response to parental requests for assistance in dealing with adolescent problem children, three parent-child pairs were taught negotiation responses to hypothetical conflict situations using behavior rehearsal and social reinforcement. The negotiation process was separated into component behaviors that were practised during simulations by each youth and his parent under the direction of trainers. Results indicated that (a) the procedures were successful in training youths and their parents in negotiation behaviors that produced agreements to conflict situations, and (b) these behaviors generalized to actual conflict situations in subjects' homes.     

AN INSTITUTIONAL STAFF TRAINING AND SELF-MANAGEMENT PROGRAM FOR DEVELOPING MULTIPLE SELF-CARE SKILLS IN SEVERELY/PROFOUNDLY RETARDED INDIVIDUALS

Although considerable attention has been given to the development of institutional staff training and management programs, the generalized effects of such programs on staff and resident behavior have seldom been examined. This study evaluated a program for teaching institutional staff behavioral training and self-management skills during self-care teaching sessions with severely and profoundly retarded residents. Following baseline observations in three self-care situations (toothbrushing, haircombing, handwashing), four direct care staff were sequentially taught to use verbal instruction, physical guidance, and contingent reinforcement in the toothbrushing program. During maintenance, staff were simultaneously taught to record, graph, and evaluate resident and their own behavior in the toothbrushing sessions. Staff were taught use of the training and self-management skills through a sequence of written instructions, videotaped and live modeling, rehearsal, and videotaped feedback. Observer presence and experimenter supervision were gradually decreased during the maintenance condition. Results indicated that during training and maintenance staff: (a) learned to use the training skills appropriately and consistently in the example situation (toothbrushing); (b) applied the skills in the generalization situations (haircombing and handwashing); and thereafter (c) maintained consistent and appropriate use of the skills with infrequent supervision. In addition, important changes in retarded residents' independent self-care responding occurred as staff training skills developed. Results are discussed in terms of their implication for future research and continued development of effective staff training and management programs.     

Programming maintenance after correspondence training interventions with children

Interventions were employed to program maintenance following correspondence training. The use of reinforcement of verbalization and a mixed sequence of procedures designed to establish indiscriminable contingencies was evaluated in multiple-baseline designs across subjects and behaviors. The results indicated that target behaviors were maintained under less intrusive interventions and in the absence of programmed contingencies during extended follow-up conditions. The results are discussed in terms of changes in reinforcement schedules established in maintenance interventions.     

Use of peer-mediated intervention in children with attention deficit hyperactivity disorder

The present experiment extended and replicated the use of functional analysis and a peer-mediated intervention to decrease disruptive behavior displayed by children diagnosed with attention deficit hyperactivity disorder in an afterschool program. After determining that the participants displayed off-task behavior maintained by peer attention via a functional analysis, peer-implemented differential reinforcement of other behavior with extinction was effective in reducing participants' off-task behaviors. The use of peers as behavior-change agents is discussed, as are avenues for future research.     

Additional free reinforcers increase persistence of problem behavior in a clinical context: A partial replication of laboratory findings

Behavioral momentum theory is a quantitative framework used to characterize the persistence of behavior during response disruptors as a function of baseline stimulus–reinforcer relations. Results of several investigations have shown that alternative reinforcement can increase the resistance to change of a target response during extinction. In the present study, concomitant variable‐interval fixed‐time schedules of reinforcement for problem behavior were employed to simulate naturalistic situations involving the superimposition of response‐independent reinforcers on a baseline schedule of reinforcement for problem behavior, as in the common use of noncontingent reinforcement treatments. Resistance to change of problem behavior was assessed during postsession periods of extinction by comparing response rates in extinction following sessions with and without additional reinforcer deliveries arranged by fixed‐time schedules. For 2 out of 3 participants, problem behavior tended to be more resistant to extinction following periods in which additional fixed‐time reinforcers were delivered. These results are discussed in terms of potential effects of noncontingent reinforcement on problem behavior when the intervention is discontinued or implemented without good treatment integrity.     

A CLASSIFICATION SCHEME OF SOCIAL CONDITIONS OF REINFORCEMENT WITHIN GROUP OPERANT SYSTEMS1

Many different reinforcement contingencies are found in group operant systems, such as token economies and point systems. Some systems use group contingencies in which the reinforcement of any one participant may depend on the behavior of some other group member. Other programs are individual, in that participants earn reinforcers dependent only on their own behavior. The various possible arrangements of people and their response requirements are labelled “social conditions of reinforcement” in this paper. Previous attempts at classification have failed to categorize the variety of social conditions of reinforcement. In addition, some conditions that may produce behaviorally different effects have not been separated. The present paper classifies the social conditions of reinforcement found in applied programs in a three-dimensional scheme. The efficacy of the three major dimensions—reinforcing agent, recipient response requirement, and group response requirement—is supported by clinical and research data. The reinforcing agent dimension refers to the person(s) who dispenses reinforcers to group members. This major dimension is further subdivided: one or several agents may be either designated or nondesignated. Recipients are the group members who receive reinforcement. This dimension is also subdivided: one or several recipients in a social condition of reinforcement may obtain reinforcers either contingently or noncontingently. The group response requirement is a criterion that must be satisfied before any group participant is eligible for reinforcement. Some systems have no group requirement, and others have a group requirement that must be met by some designated or nondesignated participant(s). Supportive references and examples are given in the explanation of each dimension and subdimension. The behavioral impact of the various categories is emphasized. For all major dimensions, applied implications and research suggestions are discussed. Concluding remarks center on the utility of the present scheme, the classification of operant procedures other than positive reinforcement, and both theoretical and applied issues requiring further study (e.g., the long-term effects of participation in group contingencies).     

Multiple reinforcement contingencies to reduce aggression,self-injury and dysfunctional verbal behaviors in an adult who is sensory impaired

Differential reinforcement of other behavior (DRO) and differential reinforcement of low rates of responding (DRL) have been effective techniques in reducing maladaptive behaviors in therapeutic settings. Reported studies of these reinforcement-based procedures indicate that they are usually implemented in isolation, targeting only a single behavior or class of behaviors. In this study, multiple DRO and DRL contingencies were utilized concurrently in reducing two distinct classes of behaviors with a 26 year-old blind man with moderate retardation. One class of behaviors included socially inappropriate verbalizations, while the other included aggressive, self-injurious and environmentally destructive behaviors. Distinct contingencies were established according to the functions of the targeted behaviors and their severity and separate schedules of reinforcement were derived from baseline frequencies. Over a period of 20 months, the differential reinforcement interventions resulted in rapid reduction of behaviors in both classes to near-zero rates and frequencies were maintained at this low level while contingency schedules were systematically lengthened. Collateral effects are discussed including performance in functional academics and participation in community integration activities.     

Student learning as the basis for reinforcement to the instructor

The present study reinforced the two instructors of two students with profound mental retardation first for the instructors' training behaviors, then for improved student learning in a multiple baseline across responses design. Reinforcement of the instructors' training behaviors increased their training behaviors, replicating the findings of previous studies, but had no effect on student learning. When the reinforcement for the instructors was instead made contingent upon student learning, the student learning improved and the instructors' high level of training behaviors was maintained. In addition, the instructors began to request training for themselves. These findings suggest that staff motivation programs for instructors might usefully base the reinforcers not only on the instructor's performance, but on the progress of their students.     

Self-reinforcement

Self-reinforcement in operant situations generally refers to those arrangements in which the subject delivers to himself a consequence, contingent on his behavior. However, it is noted that the definition of all other types of reinforcement make its delivery contingent on the subject's behavior. What is actually at issue is the agent who defines whether or not the response required for reinforcement has been met. In self-reinforcement, the subject himself defines this. In the laboratory, this requirement is machine-defined; in school examinations, it is teacher-defined; and in many clinical self-control situations, it is also independently defined. A reinforcement contingency presupposes such independence, absent in self-reinforcement. Implications for research and practice are discussed and alternative formulations are offered.     

EFFECTS OF COLLATERAL PEER SUPPORTIVE BEHAVIORS WITHIN THE CLASSWIDE PEER TUTORING PROGRAM

A classwide peer tutoring procedure was implemented in an urban elementary school classroom to improve students' spelling performance. Three students combined untrained or collateral tutoring behaviors with the core behaviors initially taught. To explore the function of these natural and spontaneous behaviors, a multielement single-subject experiment with replications was conducted. Results indicated that the additional tutoring behaviors increased (a) the academic response frequencies of 3 tutees and (b) the weekly spelling achievement of 1 target tutee. The remaining class members were successfully taught and continued to use these behaviors over the final 3 weeks of the school year. These findings are discussed with regard to academic instruction, natural communities of peer reinforcement, and the social validation of intervention procedures.     

Behavior modification with culturally deprived school children: two case studies

Techniques of behavior modification were employed with two second-grade Negro girls in a demonstration school for culturally deprived children to increase the girls' appropriate classroom behaviors. A classification system that provided for continuous categorization of behavior was used to code the children's behavior in two classroom situations. Data were also taken on the type, duration, and frequency of the teachers' verbal interactions. The study included four conditions: Baseline, Modification I, Postmodification, and Modification II. The treatment variable was positive social reinforcement-attention and approval contingent upon desirable classroom behaviors-which was presented, withheld, or withdrawn (timeout from social reinforcement). Withholding of social reinforcement was contingent upon inappropriate attention-getting behaviors. Timeout from social reinforcement was contingent upon behaviors classified as aggressive and resistive. After 25 days of Modification I, desirable behavior increased markedly for each girl. The teachers were then asked to return to their Baseline level of performance. The resultant behaviors demonstrated that for one girl, behavior was still primarily under the control of the treatment contingencies. For the second child, many desirable behaviors that had increased in frequency during Modification I remained high, but inappropriate behaviors increased. When treatment was reinstated, the amount of time spent in desirable behaviors increased and remained high for both girls. Three checks during the three months following data collection showed that these behaviors continued to remain high.     

Sex differences in reinforcement and punishment on prime-time television

Prime-time television programs were analyzed for frequencies of positive reinforcement and punishment exchanged among performers varying in age and sex. Results indicated that most responses were given by and directed to adult males. Moreover, while adult males exhibited and received similar frequencies of reinforcement and punishment, adult females were likely to give and to be the recipients of more reinforcement than punishment. Proportional analyses which controlled for sex differences in frequencies of responses revealed that females more often exhibited and received reinforcement, whereas males more often exhibited and received punishment. Results are interpreted from a social learning theory perspective and the implications for children's learning of positive and negative behaviors are explored.     

An evaluation of differential reinforcement of other behavior,differential reinforcement of incompatible behavior,and restitution for the management of aggressive behaviors

A 46 year old institutionalized retarded woman was referred for treatment because of frequent verbal abuse and physically aggressive behaviors. A multicomponent behavioral intervention consisting of differential reinforcement of other behaviors, differential reinforcement of incompatible behaviors, and restitution was implemented. A sequential withdrawal design was used in order to evaluate the effects of components of the original intervention, and to provide a measure of response maintenance. Results indicated a marked decrease in verbal abuse and elimination of physical aggression. Verbal abuse recurred when the restitution procedure was withdrawn. The relative efficacy of the different interventions is discussed with respect to the behavioral management of aggression. © 1998 John Wiley & Sons, Ltd.     

“Discredited” Versus “Discreditable”: Understanding How Shared and Unique Stigma Mechanisms Affect Psychological and Physical Health Disparities

One of the few studies to examine judgments of personal control in a contingency situation found that participants did not overestimate their control on a task where actual control was possible. However, that study used a design that confounded control and reinforcement. In this study, control (none, medium, high) and reinforcement (low, high) were independently manipulated. College students (N = 100) participated in a computer task in which they pressed or did not press the space bar, after which a target or nontarget screen appeared. Participants rated their control over the appearance of the target screen. Support was found for the idea that in some situations of actual control, illusions of control are found: high-control participants with high reinforcement overestimated their control. Results also indicated that underestimators, accurate estimators, and overestimators used different information when estimating their levels of control. Causes and implications are discussed.
