Antecedents and Consequences of Words

As instances of behavior, words interact with environments. But they also interact with each other and with other kinds of behavior. Because of the interlocking nature of the contingencies into which words enter, their behavioral properties may become increasingly removed from nonverbal contingencies, and their relationship to those contingencies may become distorted by the social contingencies that maintain verbal behavior. Verbal behavior is an exceedingly efficient way in which one organism can change the behavior of another. All other functions of verbal behavior derive from this most basic function, sometimes called verbal governance. Functional verbal antecedents in verbal governance may be extended across time and space when individuals replicate the verbal behavior of others or their own verbal behavior. Differential contact with different verbal antecedents may follow from differential attention to verbal stimuli correlated with consequential events. Once in place, verbal behavior can be shaped by (usually social) consequences. Because these four verbal processes (verbal governance, replication, differential attention, and verbal shaping) share common stimulus and response terms, they produce interlocking contingencies in which extensive classes of behavior come to be dominated by verbal antecedents. Very different consequences follow from verbal behavior depending on whether it is anchored to environmental events, as in scientific verbal practices, or becomes independent of it, as in religious fundamentalism.     

Effect of training different classes of verbal behavior to decrease aberrant verbal behavior

Inappropriate verbal behavior that is labeled "psychotic" is often described as insensitive to environmental contingencies. The purpose of the current study was to establish different classes of rational or appropriate verbal behavior in a woman with developmental disabilities and evaluate the effects on her psychotic or aberrant vocal verbal behavior. Similar to a previous study (Arntzen, Ro Tonnessen, & Brouwer, 2006), the results of the current study suggested that the procedure helped to establish a repertoire of appropriate functional vocal verbal behavior in the participant. Overall, the results suggested the effectiveness of an intervention based on training various classes of verbal behavior in decreasing aberrant verbal behavior.     

The relationship between stimulus equivalence and verbal behavior

Despite the apparent similarity between stimulus equivalence and verbal behavior, these phenomena have been described in different terms. With different terminologies for each phenomenon, the precise nature of their relationship is difficult to determine. To explore this relationship, this paper first defines stimulus equivalence using a synthesis of the mathematical definition of the equivalence relation and Sidman and Tailby’s (1982) definition. Selected examples of stimulus equivalence are then described as verbal behavior using Skinner’s (1957) terminology. The paper then cites instances of verbal behavior that cannot be described as stimulus equivalence and considers whether there are instances of stimulus equivalence that cannot be described as verbal behavior.

     

A Comparison of Topography-based and Selection-based Verbal Behavior in Typically Developed Children and Developmentally Disabled Persons with Autism

This study is a replication of Sundberg and Sundberg (1990) that compared topography-based verbal behavior with selection-based verbal behavior in terms of acquisition, accuracy, and testing for the emergence of a new verbal relation. Participants were three typical children and three developmentally disabled persons with autism. The study sought to determine which paradigm (topography-based or selection-based) resulted in more rapid acquisition of tacts and intraverbals, which was associated with the fewest errors, and which paradigm resulted in the emergence of the highest number of new verbal relations. The results of the study showed that the six participants performed quite differently from one another. Most importantly, the results from the person with autism contradicted previous findings favoring selection-based verbal behavior over topography-based approaches for teaching verbal behavior to low-functioning individuals.     

Comparing topography-based verbal behavior with stimulus selection-based verbal behavior

Michael (1985) distinguished between two types of verbal behavior: topography-based and stimulus selection-based verbal behavior. The current research was designed to empirically examine these two types of verbal behavior while addressing the frequently debated question, Which augmentative communication system should be used with the nonverbal developmentally disabled person? Four mentally retarded adults served as subjects. Each subject was taught to tact an object by either pointing to its corresponding symbol (selection-based verbal behavior), or making the corresponding sign (topography-based verbal behavior). They were then taught an intraverbal relation, and were tested for the emergence of stimulus equivalence relations. The results showed that signed responses were acquired more readily than pointing responses as measured by the acquisition of tacts and intraverbals, and the formation of equivalence classes. These results support Michael’s (1985) analysis, and have important implications for the design of language intervention programs for the developmentally disabled.

     

Empirical Applications of Skinner’s Analysis of Verbal Behavior with Humans

In Verbal Behavior, Skinner (1957) provided a conceptual framework and taxonomy for the controlling variables of language that defined independent verbal operants by their functional relations to antecedents and consequences (rather than by topography or meaning). Although professional interest in this area has recently increased within the behavior analytic community, Skinner''s conceptual framework may not yet have fully impacted the experimental literature. This quantitative review of the literature examined the studies on verbal behavior that were empirical in nature, concerned with human verbal behavior, and addressed at least one verbal operant (e.g., mand, tact, echoic, autoclitic, and/or intraverbal behavior) within the experiment. The results of this review suggest that a growing body of research exists to support many of the tenets of Skinner''s conceptualization and taxonomy but many areas of verbal behavior research have yet to be addressed. Continued research in this area is crucial for the development and implementation of effective verbal behavior interventions for people with disabilities.     

Behavioral Stability Across Time and Situations: Nonverbal Versus Verbal Consistency

Behavioral consistency has been at the center of debates regarding the stability of personality. We argue that people are consistent but that such consistency is best observed in nonverbal behavior. In Study 1, participants’ verbal and nonverbal behaviors were observed in a mock interview and then in an informal interaction. In Study 2, medical students’ verbal and nonverbal behaviors were observed during first- and third-year clinical skills evaluation. Nonverbal behavior exhibited consistency across context and time (a duration of 2 years) whereas verbal behavior did not. Discussion focuses on implications for theories of personality and nonverbal behavior.     

Quantified trends in the history of verbal behavior research

The history of scientific research about verbal behavior research, especially that based on Verbal Behavior (Skinner, 1957), can be assessed on the basis of a frequency and celeration analysis of the published and presented literature. In order to discover these quantified trends, a comprehensive bibliographical database was developed. Based on several literature searches, the bibliographic database included papers pertaining to verbal behavior that were published in the Journal of the Experimental Analysis of Behavior, the Journal of Applied Behavior Analysis, Behaviorism, The Behavior Analyst, and The Analysis of Verbal Behavior. A nonbehavioral journal, the Journal of Verbal Learning and Verbal Behavior was assessed as a nonexample comparison. The bibliographic database also included a listing of verbal behavior papers presented at the meetings of the Association for Behavior Analysis. Papers were added to the database if they (a) were about verbal behavior, (b) referenced B.F. Skinner’s (1957) book Verbal Behavior, or (c) did both. Because the references indicated the year of publication or presentation, a count per year of them was measured. These yearly frequencies were plotted on Standard Celeration Charts. Once plotted, various celeration trends in the literature became visible, not the least of which was the greater quantity of verbal behavior research than is generally acknowledged. The data clearly show an acceleration of research across the past decade. The data also question the notion that a “paucity” of research based on Verbal Behavior currently exists. Explanations of the acceleration of verbal behavior research are suggested, and plausible reasons are offered as to why a relative lack of verbal behavior research extended through the mid 1960s to the latter 1970s.

     

The Importance of Form in Skinner’s Analysis of Verbal Behavior and a Further Step

A series of quotes from B. F. Skinner illustrates the importance of form in his analysis of verbal behavior. In that analysis, form plays an important part in contingency control. Form and function complement each other. Function, the array of variables that control a verbal utterance, dictates the meaning of a specified form; form, as stipulated by a verbal community, indicates that meaning. The mediational actions that shape verbal utterances do not necessarily encounter their controlling variables. These are inferred from the form of the verbal utterance. Form carries the burden of implied meaning and underscores the importance of the verbal community in the expression of all the forms of language. Skinner''s analysis of verbal behavior and the importance of form within that analysis provides the foundation by which to investigate language. But a further step needs to be undertaken to examine and to explain the abstractions of language as an outcome of action at an aggregate level.     

Participant and observer attribution of affect in interpersonal conflict: An examination of noncontent verbal behavior

This investigation explored the relationship between observer and participant attribution of affect intensity in interpersonal conflict interaction and the occurrance of verbal behavior. It was predicted that observer's judgments of affect intensity would account for more variation in verbal behavior that represents conflict than would participant's judgments of affect intensity. Videotapes of 37 dyadic conflict interactions were examined. The results indicate that one observer's judgment of affect intensity was a much better predictor of verbal behavior than were the other observer's judgment of affect intensity or either of the two participant's judgments of affect intensity. While some evidence was yielded to suggest that observers are more likely to be sensitive to behavior in their attribution of affect intensity than are participants, these results imply significant differences in the attribution of affect between some observers.     

Equivalence class formation in non-hearing impaired children and hearing impaired children

The relationship between verbal behavior and stimulus equivalence was examined using three sets of children differing in chronological age and verbal ability: (1) non-hearing impaired three and four year olds who had verbal skills generally consistent with their chronological ages; (2) partially hearing (severe to profoundly deaf) children who were rated with verbal ages of above 2 years; and (3) partially hearing children (also severely to profoundly deaf) who were rated with verbal ages of below 2 years. All children were taught a series of four conditional discriminations using unfamiliar stimuli. The children were then tested to determine whether classes of equivalent stimuli had formed. Although all the children were able to learn the conditional discriminations equally well and all the verbally-able children (normal and partially hearing) formed equivalence classes, only one of the verbally-impaired children reliably demonstrated stimulus equivalence formation. These results are consistent with the suggestion that stimulus equivalence and human verbal behavior are closely related.

Meaning and Verbal Behavior in Skinner's Work from 1934 to 1957

This paper explores the historical development of Skinner''s treatment of meaning from 1930 to 1957. Twelve papers published between 1934 and 1957, and parts of The Behavior of Organisms and Science and Human Behavior related to verbal behavior, were analyzed. Before 1945 meaning was taken as a property of the verbal response, and from 1945 on, meaning was supposed to be found among the determiners of a verbal response. We argue that these different conceptions of meaning were related to distinct aspects of Skinner''s explanatory system. Finally, the notion of meaning presented by Skinner in 1945 is related to the theoretical breakthrough represented by Skinner''s assertion of the three-term contingency. This idea permitted verbal behavior to be analyzed in terms of its functions.     

Conditional Discrimination in the Intraverbal Relation: A Review and Recommendations for Future Research

Conditional discrimination is inherent in the intraverbal relation when one verbal stimulus alters the evocative effect of another verbal stimulus and they collectively evoke an intraverbal response. Rarely in research on conditional discriminations have both conditional and discriminative stimuli been vocal verbal and rarely have the responses been topography-based. Making conditional discriminations in intraverbal behavior is a repertoire that is often delayed in children with autism and other developmental disabilities. Reviewed in this paper is research on teaching intraverbal behavior, auditory conditional discriminations, and restricted stimulus control. The purpose of these reviews is to identify the extent to which previous researchers examined conditional discriminations in the intraverbal relation and to recommend directions for research in this area.     

The last ten turns: Behavior and sequencing in friends' and strangers' conversational findings

This study examined the verbal and nonverbal behaviors which characterize the ends of two-person face-to-face interactions. It was hypothesized that sequences of both verbal and nonverbal behavior would be present in conversational endings and that nonverbal behaviors would occur with different frequency in the middle and at the end of conversations. It was also predicted that both verbal and nonverbal behavior in conversational endings between friends and between strangers would differ. Ten dyads of friends and ten dyads of strangers, all female, were videotaped while in relatively unconstrained conversation. The content of verbal statements and the occurrence or nonoccurrence of 13 nonverbal behaviors in the ten middlemost and the ten last turns were analyzed. Results indicated that the seven verbal statement types formed a sequence of information, summary, question, verbalization, justification, continuity, and well-wishing. Six clusters of nonverbal behavior distinguished the ending phase from the middle phase; these behaviors were organized into a general sequential pattern, but the positions of several behaviors within the sequence were subject to variation. Finally, three clusters of nonverbal behaviors (more looking away, more grooming, less head nodding) distinguished conversation endings between friends from those between strangers.We are grateful to Helen McKenna and Peter Pamment for their help. We also appreciate the comments given by Dr. Judee, K. Burgoon, and an anonymous reviewer.

Constructs and Events in Verbal Behavior

Skinner''s (1957) analysis of verbal behavior has been the subject of much controversy in recent years. While criticism has historically come from outside the field of behavior analysis, there are now well-articulated arguments against Skinner''s analysis of verbal behavior from within the field as well. Recently, advocates of Skinner''s analysis have attempted to respond to the critiques, particularly to those regarding Skinner''s definition of verbal behavior articulated by proponents of relational frame theory. Specifically, it has been suggested that talk about definitions equates to making the essentialist error. This paper provides an overview of these issues in the context of understanding the role of constructs in science more generally. It will be argued that definitions are central to scientific progress, and are not only relevant to a functional analysis, but a central prerequisite to the pursuit of such an analysis.
