Realizing the potential of Skinner's analysis of verbal behavior

Whither the muse: What influences empirical research on verbal behavior?

To identify some of the published works that have helped to inspire empirical verbal behavior research, we searched for patterns in the sources cited in empirical studies published in The Analysis of Verbal Behavior between 1990 and 1999. Not unexpectedly, Skinner's (1957) Verbal Behavior was the most cited source, although a variety of more recent sources explicating verbal relations as conceptualized by Skinner also were frequently cited. About one third of the most frequently cited sources were fairly recent primary empirical papers. These outcomes suggest that scholars who are interested in a behavior-analytic approach to studying verbal behavior are beginning to generate a critical mass of work that renders Verbal Behavior no longer monolithic in its influence. Nevertheless, some aspects of the citation data could be interpreted as evidence of insularity, and we argue for the importance of a broad-based analysis of verbal behavior that can have substantial impact outside of behavior analysis.

Assessing transfer of stimulus control procedures across learners with autism

The purpose of this study was to evaluate the effectiveness of 2 transfer of stimulus control procedures to teach tacting to individuals with autism. Five participants with differing verbal skills were assessed by a subset of the ABLLS prior to intervention, then were taught 36 previously unknown tacts using the receptive-echoic-tact (r-e-t) and echoic-tact (e-t) transfer procedures. Each transfer method was used separately to establish different tacts, in a multiple baseline design across tacts for 3 sets of stimuli. The results showed that 4 out of 5 participants (who demonstrated mands, tacts, echoics, and sometimes intraverbals prior to the study) acquired all targeted tacts when either r-e-t or e-t training was presented. One participant (who emitted no verbal operants at the onset of the study) did not acquire any tacts. While some participants appeared to learn more quickly with one transfer method, neither method emerged as more efficient with learners with fewer or more extensive verbal skills. The results indicate that both transfer methods promoted the acquisition of tacts for learners with autism with at least minimal verbal skills.

Linguistic Sources of Skinner's Verbal Behavior

Formal and functional analyses of verbal behavior have been often considered to be divergent and incompatible. Yet, an examination of the history of part of the analytical approach used in Verbal Behavior (Skinner, 1957/1992) for the identification and conceptualization of verbal operant units discloses that it corresponds well with formal analyses of languages. Formal analyses have been carried out since the invention of writing and fall within the scope of traditional grammar and structural linguistics, particularly in analyses made by the linguist Leonard Bloomfield. The relevance of analytical instruments originated from linguistic studies (which examine and describe the practices of verbal communities) to the analysis of verbal behavior, as proposed by Skinner, relates to the conception of a verbal community as a prerequisite for the acquisition of verbal behavior. A deliberately interdisciplinary approach is advocated in this paper, with the systematic adoption of linguistic analyses and descriptions adding relevant knowledge to the design of experimental research in verbal behavior.

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.
