PREPARATION FOR EFFECTIVE SELF-REGULATION: THE DEVELOPMENT OF GENERALIZED VERBAL CONTROL

A correspondence training procedure was used to develop consistency between children's verbalizations and their subsequent behavior across increasingly remote settings and time. The interval of time between the verbalizations and the opportunity to engage in several target behaviors was systematically increased across four preschool settings. Probes of generalized verbal control of home behaviors were conducted throughout training and showed that generalization was obtained in the absence of any salient externally imposed contingencies after the children had reliably come under the control of verbalizations about preschool behaviors.     

THE EFFECTIVENESS OF VERBAL INSTRUCTION ON TEACHING BEHAVIOR-MODIFICATION SKILLS TO NONPROFESSIONALS1

The effectiveness of a mastery criterion, lecture-based training program for teaching behavior modification to sheltered workshop personnel was evaluated. Staff performance was assessed in terms of: (1) verbal proficiency, as determined from a pre- and posttraining written exam, and (2) application proficiency, as measured by the frequency and appropriateness of staff responses to client behaviors. A direct count was made of the number of positive, negative, and neutral statements following client appropriate and inappropriate behaviors, and the number and type of client behaviors ignored. Thus, it was possible to determine the extent of generalization from classroom to applied settings, as well as the appropriateness of lectures for training specific performance skills. Lecture units introduced stimulus control procedures, shaping-chaining, and contingency management. Characteristic features of the training program were frequent testing, study objectives, immediate remediation, and contingent reinforcement. Verbal instruction was shown to be effective in improving subjects' verbal skills concerning behavior-modification principles, while only partially effective in improving application skills. There was an increase in the total number of staff-client interactions observed for all subjects, but only two of the response classes emphasized in the training program (reinforcing desirable client behavior and ignoring undesirable behavior) showed considerable improvement over pretraining levels. Despite this partial improvement, verbal instruction alone was shown to be insufficient for teaching the full range of behavior-modification skills required to function effectively in applied settings.     

GENERALIZATION BY AUTISTIC-TYPE CHILDREN OF VERBAL RESPONSES ACROSS SETTINGS

Generalization of verbal behavior by autistic-type children across physically different settings was assessed. Four boys learned responses to common questions in two settings at school and were probed to determine transfer of learning to home. Three of the children demonstrated little generalization to home when trained in a cubicle. Greater generalization was indicated when they received training at varied locations. The fourth child generalized most responses to his home regardless of training setting. Simple manipulations of the school environment to more closely simulate home conditions may facilitate transfer of training to the natural environment.     

EMPLOYING TASK ARRANGEMENTS AND VERBAL CONTINGENCIES TO PROMOTE VERBALIZATIONS BETWEEN RETARDED CHILDREN1

This study investigated the effects of arranging task events for interdependence, to increase the probability of social responding. During task interdependence, the subjects, participating in dyads and a four-person group, obtained task materials (a puzzle piece) from their partner before completing their task (appropriately placing the puzzle piece). The verbal contingency required a verbal request to precede a subject's receiving a task material from his partner. The verbal contingency yoked with task interdependence made task completion contingent on the appropriate verbalization. The findings from two experiments suggested that task interdependence was sufficient to increase partner-directed verbalizations for three of the four subjects. When the verbal contingency was added, all subjects increased their requests and other verbalizations to partner. Applied to a four-person group, the verbal contingency yoked with varying levels of task interdependence correspondingly affected the pattern and level of group communications. The greater the task interdependence, i.e., the more members each subject depended on to complete his task, the more complex the social network of verbal contacts, and the higher the level of both requests and other verbalizations for the group.     

INCREASING APPROPRIATE SPEECH IN A CHRONIC SCHIZOPHRENIC

In a severely withdrawn schizophrenic, a combination of instructions, modeling, informational feedback, and noncontingent reinforcement was associated with a low rate of appropriate verbalizations. However, an increase in speech output was obtained using a combination of instructions, modeling, informational feedback, and contingent reinforcement. The design of this study thus permitted the conclusion that contingent reinforcement was crucial in bringing about the increase in appropriate verbalizations. The three verbal behaviors that increased in frequency were: (a) the number of socially appropriate words emitted, (b) declarative statements, and (c) appropriate replies to questions. The verbal behaviors of conversational questions and positive conversational feedback failed to be significantly affected by the experimental procedures. An attempt was also made to establish whether having the subject engage in the observable, information-gathering response of reading aloud would result in increased speech output during a subsequent conversation period. Having the subject read aloud failed to have any discernible positive effect on his speech output. A withdrawal design was used to evaluate the effectiveness of the experimental procedures. The importance of assessing changes in verbal output with a variety of verbal response measures, stereotyped verbal behaviors, and carryover effects are discussed.     

Toddler emotion expressions and emotional traits: Associations with parent-toddler verbal conversation

The present study examines how toddler emotions may influence their own or their parents’ participation in parent-toddler verbal conversation. Limited, indirect evidence suggests that toddler positive emotions may encourage, whereas negative emotions may disrupt, parent-toddler verbal exchanges, but these hypotheses have not been tested directly. We investigated two aspects of toddler emotions– their emotion expressions and their emotional traits– and examined their relations with parent-toddler verbal conversation engagement. In a sample of families with 18-month-olds (N = 120), we used live, unstructured home observations of toddler emotion expressions and spontaneous parent-toddler verbalizations, and collected parent ratings of toddler temperament. We found that less surgent toddlers who expressed more frequent negative emotion attempted fewer verbalizations. Among all toddlers, those expressing positive emotion received more frequent parent verbal responses, and, unexpectedly, more failed parent attempts to engage their toddler in conversation. Parent-initiated conversation was unrelated to toddler emotion expressions or emotional traits. We discuss how best to integrate the study of early emotional and language development from a transactional perspective.     

AN INVESTIGATION OF THE EFFECTS OF TOKEN REINFORCEMENT ON DIVERGENT VERBAL RESPONDING1

The effect of token reinforcement on three classes of divergent verbal responding to verbal stimulus items from three measures of the Wallach-Kogan Creativity test was examined. The subjects consisted of two “gifted”, two “average”, and two “learning disabled” children from a public-school setting. The design utilized both an intra-subject and inter-subject multiple-baseline design with a reversal design added. Tokens were dispensed contingent upon the number of appropriate verbal responses to each stimulus item, i.e., a continuous schedule of reinforcement was used—one token per appropriate response. Interobserver agreement on “appropiateness” was 993%. The tokens could be used to “purchase” items listed in a “menu” format (e.g., ball and jacks—100 tokens). Consistently large effects of token reinforcement were observed, without generalization of effect across the three classes of behaviors, or conditions. These results support the works of Goetz and Baer (Journal of Applied Behavior Analysis, 1973, 6 , 209–217), Goetz and Salmonson (Behavior Analysis and Education, G. Semb, (Ed.), University of Kansas, 1972, 53–61), and Maloney and Hopkins (Journal of Applied Behavior Analysis, 1973, 6 , 425–434). Implications lie in continued experimental analysis of behavior approach to the concept called “creativity”. Additionally, implications are made in classroom application of assessing and intervening in the area of divergent responding for children with deficits in those areas.     

Increasing mentally retarded adolescents' verbalizations about current events

The effects of antecedent and consequent events on the verbal behavior of three institutionalized mentally retarded adolescents were examined. Verbal statements, related to current national and international events, were recorded after exposures to television news programs. The study examined the accuracy of verbalizations as a function of: (1) exposures to television news presentations in massed (i.e., viewing the entire news program before an opportunity to describe it) versus distributed from (i.e., viewing each news item separately with each followed by an opportunity to describe it), and (2) contingent tokens and social praise for correct verbal responses (i.e., statements corresponding to news items presented). Both the temporal distribution of news presentations and the reinforcement procedures improved the accuracy of verbal statements emitted by the subjects.     

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.     

MODIFICATION OF VERBAL BEHAVIOR OF THE MENTALLY IMPAIRED ELDERLY BY THEIR SPOUSES

Speaking disorders frequently result in serious consequences for mentally impaired elderly people. Two examples are presented illustrating the modification of both excess and deficit rates of talking via differential reinforcement procedures. Two men exhibiting verbal disorders severe enough to impair social interactions and lead to possible nursing home placement were treated by teaching their spouses to reinforce positive and ignore undesired verbal responses. Problem behaviors were reduced sufficiently to permit continued home care, and alternative positive behaviors were increased. These findings suggest that verbal behavior of the mentally impaired elderly can be affected by applying systematic consequences and can be modified by relatively simple procedures. These procedures provide an alternative to the negative effects of labels associated with either aversive or deficient verbal behaviors, promote more positive activities, and enable continued residence at home. Further, this research provides support for the generality of the utility of training spouses to serve as behavior therapists for the impaired elderly.     

REPLACING MALADAPTIVE SPEECH WITH VERBAL LABELING RESPONSES: AN ANALYSIS OF GENERALIZED RESPONDING

We taught three mentally handicapped students to answer questions with verbal labels and evaluated the generalized effects of this training on their maladaptive speech (e.g., echolalia) and correct responding to untrained questions. The students received cues-pause-point training on an initial question set followed by generalization assessments on a different set in another setting. Probes were conducted on novel questions in three other settings to determine the strength and spread of the generalization effect. A multiple baseline across subjects design revealed that maladaptive speech was replaced with correct labels (answers) to questions in the training and all generalization settings. These results replicate and extend previous research that suggested that cues-pause-point procedures may be useful in replacing maladaptive speech patterns by teaching students to use their verbal labeling repertoires.     

EVALUATION AND TRAINING OF YES‐NO RESPONDING ACROSS VERBAL OPERANTS

Topographically similar verbal responses may be functionally independent forms of operant behavior. For example, saying yes or no may have different functions based on the environmental conditions in effect. The present study extends previous research on both the assessment and acquisition of yes and no responses across contexts in children with language deficits and further examined the functional independence of topographically similar responses. All participants in the present study acquired yes and no responses within verbal operants (e.g., mands). However, generalization of the responses across novel verbal operants (e.g., tacts to intraverbals) did not occur without additional training, thus supporting Skinner's (1957) assertion of functional independence of verbal operants.     

INCREASING VERBAL INTERACTION AMONG ELDERLY SOCIALLY ISOLATED MENTALLY RETARDED ADULTS: A GROUP LANGUAGE TRAINING PROCEDURE

The present study examined the effectiveness of a group language training procedure for directly increasing and generalizing the rate of verbal interaction among four elderly, socially isolated, moderately mentally retarded men. A withdrawal of treatment design was used to examine the effect of the procedure that used verbal prompts, behavioral rehearsal, and contingent social praise. Changes in behavior were examined in two generalization settings, one similiar to the training environment (Generalization I) and the other arranged as part of the subjects' daily routine (Generalization II). Baseline data indicated no verbal interaction among the subjects. During treatment the training procedure increased the rate of subjects' verbal interactions not only in the training situation, but also in the two generalization settings. An analysis of the data obtained during the Generalization II situation indicated that subjects' verbal interaction increased not only among themselves, but with nonsubject peers present in this setting. Follow-up data showed that increases in rates of verbal interaction were maintained four months after the cessation of training. The implications of the results for program generalization and work with the language deficient individual is discussed.     

INCREASED PEER-TEACHING WITH GROUP-ORIENTED CONTINGENCIES FOR ARITHMETIC PERFORMANCE IN BEHAVIOR-DISORDERED ADOLESCENTS1

Group-oriented contingencies were applied to increase the arithmetic problem-solving rates of four behavior-disordered adolescent residents in a psychiatric hospital. The experiment followed an ABAC reversal design consisting of baseline conditions (A₁ and A₂), and cumulative (B) and mixed (C) interdependent group-oriented contingency conditions. Under the cumulative arrangement, the subjects earned five cents for every correctly solved multiplication problem. The same conditions were in effect with the mixed contingency, except that each subject was required to work at least three problems before any subject could earn money. The results indicated consistent increases in the subjects' arithmetic computation rates as a function of the group-oriented contingencies. Concurrent observations were made across the four conditions of the experiment on four categories of the subjects' verbalizations: antecedent peer-teaching, consequent peer-teaching, positive statements, and negative statements. The subjects' rates of antecedent peer-teaching verbalizations covaried with the group-contingency-induced increases in their levels of computation behavior. The majority of the verbalization involved answers to number fact questions or redirecting peers to engage in on-task activities. The three other categories of the subjects' verbalizations that were observed—consequent peer-teaching, positive statements, and negative statements—were not found to covary with the subjects' altered rates of computation behavior.     

Modification of symptomatic verbal behaviour of mental patients

The clinically significant verbal behaviour exhibited by three mental patients was systematically manipulated by controlling the reaction of ward staff to the patients' verbalizations. When social reinforcement was made dependent upon symptomatic verbal responses, these responses increased in frequency. Withholding social reinforcement (extinction) resulted in a decrease in the frequency of symptomatic verbal responses. These techniques are now being used in the modification of verbal behaviour of schizophrenic patients.     

Modification of verbal behavior through variable interval reinforcement in a quasi-therapy situation

Principles from the operant conditioning laboratory were applied to the verbal behavior of female college students. An experimental setting was designed to replicate a psychotherapist's office, and subjects were seen daily in a study using a functional research design. Variable interval reinforcement was employed to modify the rate of emission of positive self-reference statements. Results demonstrated that the verbal, scheduled reinforcement exerted a definite, marked effect on the verbal behavior of the subjects. All subjects conditioned to the schedules. Sequence of scheduling did not appear to be a significant variable. The feasibility of employing such techniques in actual psychotherapy is discussed.     

ON THE REINFORCING EFFECTS OF THE CONTENT OF VERBAL ATTENTION

During a functional analysis, a boy with autism and oppositional defiant disorder displayed destructive behavior that was maintained by attention in the form of verbal reprimands (e.g., “Don't hit me”). In a second analysis, contingent verbal reprimands produced higher rates of the behavior than contingent statements that were unrelated to the target response (e.g., “It is sunny today”), suggesting that some forms of attention were more reinforcing than others. A treatment based on these analyses reduced the behavior to near-zero levels.     

Delusional verbalizations and beliefs

This study evaluated the intensity of delusional beliefs during the modification of delusional verbalizations with three chronically mentally ill inpatients. The multiple-baseline across responses design was used to evaluate the efficacy of a behavioral treatment package to modify delusional verbalizations. Results revealed that changes were obtained in delusional verbalizations to personal questions without corresponding changes in the subjects' delusional beliefs. Changes in delusional verbalizations were well-maintained for two subjects during a 6-month follow-up period. Mixed results were obtained for generalization probe interviews.     

TEACHING A STUDENT WITH AUTISM TO MAKE VERBAL INITIATIONS: EFFECTS OF A TACTILE PROMPT

This study examined the effects of a tactile prompting device (the Gentle Reminder) as a prompt for a student with autism to make verbal initiations about his play activities. A multiphase multielement design was used to assess the effects of the device in prompting initiations toward an adult in three different play contexts. Follow-up probes were conducted during cooperative learning activities with typically developing peers in the student's regular education class. The results suggest that the device serves as an effective, unobtrusive prompt for verbal initiations during play contexts and during cooperative learning activities.
