Citation Analysis of Skinner's Verbal Behavior: 1984-2004

Evidence From Children with Autism that Derived Relational Responding is a Generalized Operant

We conducted an empirical examination of derived relational responding as a generalized operant and concurrently evaluated the validity and efficacy of program items contained in the Promoting the Emergence of Advanced Knowledge - Equivalence (PEAK-E) curriculum. A first study utilized a multiple-baseline across-skills experimental arrangement to determine the efficacy of equivalence-based instruction guided by PEAK-E, replicated across 11 children with autism. A total of 33 individualized skills were taught, and the subsequent emergence of untrained relations was tested throughout the investigation. The mastery criterion was achieved for 29 of the 33 instructional targets. Additionally, for 3 participants, results were again replicated with a novel set of stimuli. A second study evaluated the degree to which multiple-exemplar equivalence-based instruction led to the emergence of derived relational responding as a generalized operant. The organized nature of the PEAK curriculum allowed the impact on derived relational responding to be compared to that produced by earlier PEAK models that are focused on the direct training of traditional verbal operants. PEAK-E instruction was introduced in a multiple-baseline design across two participants, with a third staying in a training baseline throughout. Increases in derived relational responding using novel, untrained stimuli were only observed when multiple-exemplar equivalence-based instruction was introduced. Taken together, these results provide support for derived relational responding as a generalized operant and demonstrate the utility of conducting larger scale evaluations of higher order behavioral phenomena in single-case experimental arrangements.

Derived Relational Responding and Transformations of Function in Children: A Review of Applied Behavior-Analytic Journals

Theoretical extensions of Skinner's verbal behavior that emphasize derived relational responding (stimulus equivalence, relational frame theory, and bidirectional naming) can improve the complexity and scope of applied behavior-analytic training models with children. We evaluated the prevalence and content of empirical research on derived relational responding in children within 8 major applied behavior-analytic journals. We identified 123 empirical articles that met all inclusion criteria (i.e., they demonstrated derived relational responding in children). Whereas prior citation analyses have shown higher rates of research with adult participants, considerable research within these journals has involved child participants. In addition, 55% of the research targeted socially relevant or culturally established verbal relations, rather than culturally arbitrary relations (e.g., unknown symbols, consonant-vowel-consonant combinations) that are unlikely to affect real-world behavior. Generalization and transformation tests were also present in 47% of articles. We also conducted a content analysis of all articles that contained culturally relevant relations and demonstrated generalization or transformation of stimulus function (21% of all articles, N = 26); we argue that studies that meet these criteria are likely to be the most immediately impactful for learners. Results suggest that future research is needed to evaluate relational frames other than coordination (e.g., distinction, opposition), as well as to extend considerably the complexity of target relational classes and transformations of stimulus function with children.

Citation Analysis of The Analysis of Verbal Behavior (2008-2018)

Recent articles by the editorial board of The Analysis of Verbal Behavior (TAVB) include calls for greater integration, collaboration, and inclusion. In so doing, it may be helpful to consider TAVB's current reach. Previously, Petursdottir, Peterson, and Peters (The Analysis of Verbal Behavior, 25, 109-121, 2009) described the number of citations of articles published in TAVB from 1983 to 2007. The authors found that the greatest number of references to TAVB were self-citations, followed predominantly by other behavior-analytic outlets, such as the Journal of Applied Behavior Analysis. Here, we replicate and extend the work of Petursdottir et al. (The Analysis of Verbal Behavior, 25, 109-121, 2009) by conducting a citation analysis of references included in TAVB publications from 2008 to 2018 and also report citations by these venues to TAVB. This citation analysis allows for a more recent review of those outlets that articles published in TAVB commonly reference and those that cite TAVB. Generally, self-citations predominated, with articles published in TAVB commonly referencing books and chapters. The implications of these practices on the impact of TAVB and suggestions for moving forward are considered.

Model Dependent Realism and the Rule-Governed Behavior of Behavior Analysts: Applications to Derived Relational Responding

A fundamental assumption within radical behaviorism is that all human behavior, including the rule-governed behavior of scientists, can be understood within a functional account. I propose that models of human behavior can be best described as a set of rules that are selected by behavior analysts to solve applied challenges, rather than descriptions of nature as it "truly exists." Model dependent realism (MDR) developed within the field of physics may provide useful criteria that could allow behavior analysts to more accurately track the relative probability of success of a given model within applied contexts. As a case example, I examine dispersive models of derived relational responding in terms of the criteria outlined within MDR, and I describe a preliminary level-scaling account of derived relational responding that encompasses several models in pursuit of a unified account. The account is context dependent and adopts a pragmatic truth criterion, consistent with assumptions within functional contextualism and radical behaviorism as an overarching rule governing the behavior of our applied subfield.

Resolving Barriers to an Applied Science of the Human Condition: Rule Governance and the Verbal Behavior of Applied Scientists

Rules / verbal behavior governing applied behavior scientists since Skinner have achieved great success resolving challenges experienced by individuals with severe developmental and intellectual disabilities. We extend prior work by Dixon, Belisle, Rehfeldt, and Root (2018, "Why We Are Still Not Acting to Save the World: The Upward Challenge of a Post-Skinnerian Behavior Science," Perspectives on Behavior Science, 41, 241-267) by suggesting that many of these rules, applied inflexibly, are unlikely to resolve significant problems experienced by humans without these same intellectual challenges (i.e., most humans). Particularly, methodological models of human behavior that ignore both private events and advances in relational frame theory and that favor a bottom-up inductive theorizing have not, and we argue cannot, address uniquely human challenges. Instead, we propose alternative rules developed in part within contextual behavior science that are more consistent with Skinner's radical behaviorism than are current approaches and that may expand the scope of applied behavior science. Only by adapting our own public and private verbal behavior as applied scientists can we move toward solving the wide range of challenges within the human condition.

Establishing arbitrary comparative relations and referential transformations of stimulus function in individuals with autism

Relational Frame Theory posits that complex language develops through arbitrarily applicable relational networks, with potential implications for individuals with autism. Responding relationally based on comparison occurs when participants respond to any number of comparative properties, such as "bigger" or "faster." Experiment 1 established two 3-member comparative networks, in which a stimulus A was conditioned as "bigger" or "faster" than a stimulus B, and the stimulus B was conditioned as "bigger" or "faster" than a stimulus C in 2 children with autism. Both participants met the mastery criterion for the trained relations and demonstrated the emergence of the untrained combinatorially entailed A-C and C-A relations. The participants could also match the arbitrary A stimuli with larger or faster objects and the C stimuli with smaller or slower objects. The results were replicated in Experiment 2 with the same participants, where a 5-member relational network was established for the bigger/smaller relation.

Why We Are Still Not Acting to Save the World: the Upward Challenge of a Post-Skinnerian Behavior Science

Basic research on derived stimulus relations reveals many effects that may be useful in understanding and resolving significant and complex societal problems. Applied research on derived stimulus relations has done little to fulfill this promise, focusing instead mainly on simple demonstrations of well-known phenomena. We trace the research tradition of derived stimulus relations from laboratory to wide-scale implementation, and put forward several suggestions for how to progress effective and impactful research on derived relational responding to issues of immense social importance. To advance a science of behavior from relative social obscurity to the developing world-saving technologies, we must evaluate our own behavior as scientists in the grander social context.

The effectiveness of the peak relational training system and corresponding changes on the VB-MAPP for young adults with autism

The current investigation sought to extend prior research evaluating the use of the PEAK Relational Training System as a comprehensive treatment model in improving language skills demonstrated by individuals with autism. Baseline PEAK-Direct Training and Verbal Behavior Milestone Assessment and Placement Program (VB-MAPP) assessments were conducted across 3 adult male participants, and scores on the PEAK-Direct Training assessment were used to select targets for intervention. Language instruction guided by the PEAK-Direct Training module was implemented for 45 to 69 days across participants. Results suggest that participants mastered target skills throughout the training phase, and VB-MAPP test probes showed an increasing trend. Follow-up probes suggested that scores on the VB-MAPP maintained when training was discontinued. In addition, participants demonstrated an increase in assessment scores on the PEAK-Direct Training assessment in the follow-up phase, including the mastery of untargeted verbal skills.

An Internal and Critical Review of the PEAK Relational Training System for Children with Autism and Related Intellectual Disabilities: 2014-2017

The PEAK Relational Training System was designed as an assessment instrument and treatment protocol for addressing language and cognitive deficits in children with autism. PEAK contains four comprehensive training modules: Direct Training and Generalization emphasize a contingency-based framework of language development, and Equivalence and Transformation emphasize an approach to language development consistent with Relational Frame Theory. The present paper provides a comprehensive and critical review of peer-reviewed publications based on the entirety PEAK system through April, 2017. We describe both psychometric and outcome research, and indicate both positive features and limitations of this body of work. Finally, we note several research and practice questions that remain to be answered with the PEAK curriculum as well as other many other autism assessment and treatment protocols that are rooted within the framework of applied behavior analysis.

The impact of Verbal Behavior on the scholarly literature from 2005 to 2016

B. F. Skinner's (1957) Verbal Behavior had a limited influence on empirical research in the first few decades following its publication, but an increase in empirical activity has been evident in recent years. The purpose of this article is to update previous analyses that have quantified the influence of Verbal Behavior on the scholarly literature, with an emphasis on its impact on empirical research. Study 1 was a citation analysis that showed an increase in citations to Verbal Behavior from 2005 to 2016 relative to earlier time periods. In particular, there was a large increase in citations from empirical articles. Study 2 identified empirical studies in which a verbal operant was manipulated or measured, regardless of whether or not Verbal Behavior was cited, and demonstrated a large increase in publication rate, with an increasing trend in the publication of both basic and applied experimental analyses throughout the review period. A majority of the studies were concerned with teaching verbal behavior to children with autism spectrum disorder and other developmental disabilities, but a variety of other basic and applied research topics were also represented. The results suggest a clearly increasing impact of Verbal Behavior on the experimental analysis of behavior on the 60th anniversary of the book's publication.

Teaching metaphorical extensions of private events through rival-model observation to children with autism

The study evaluated the efficacy of observational learning using the rival-model technique in teaching three children with autism to state metaphorical statements about emotions when provided a picture, as well as to intraverbally state an appropriate emotion when provided a scenario and corresponding metaphorical emotion. The results provide a preliminary evaluation of how an observational teaching strategy may be effective in teaching children with autism to correctly tact emotions when given metaphors.

Teaching Complex Verbal Operants with the PEAK Relational Training System

The present study evaluated the effectiveness of five packaged protocols from the Promoting the Emergence of Advanced Knowledge (PEAK) curriculum. The skills targeted in the study included complex verbal operants proposed by Skinner (Verbal behavior. Englewood Cliffs, NJ: Prentice Hall, 1957), an area that is lacking in the current literature. The target skills included autoclitics, metonymical tacts, tacting planet names, and guessing. The results suggest that the PEAK methodology was effective in teaching each of the targeted skills to a mastery criterion, as well as maintenance of those skills at a 2-week follow-up phase.

Evaluating the evidence base for relational frame theory: a citation analysis

Relational frame theory (RFT) is a contemporary behavior-analytic account of language and cognition. Since it was first outlined in 1985, RFT has generated considerable controversy and debate, and several claims have been made concerning its evidence base. The present study sought to evaluate the evidence base for RFT by undertaking a citation analysis and by categorizing all articles that cited RFT-related search terms. A total of 174 articles were identified between 1991 and 2008, 62 (36%) of which were empirical and 112 (64%) were nonempirical articles. Further analyses revealed that 42 (68%) of the empirical articles were classified as empirical RFT and 20 (32%) as empirical other, whereas 27 (24%) of the nonempirical articles were assigned to the nonempirical reviews category and 85 (76%) to the nonempirical conceptual category. In addition, the present findings show that the majority of empirical research on RFT has been conducted with typically developing adult populations, on the relational frame of sameness, and has tended to be published in either The Psychological Record or the Journal of the Experimental Analysis of Behavior. Overall, RFT has made a substantial contribution to the literature in a relatively short period of time.

Extended Analysis of Empirical Citations with Skinner's Verbal Behavior: 1984-2004

The present paper comments on and extends the citation analysis of verbal operant publications based on Skinner's Verbal Behavior (1957) by Dymond, O'Hora, Whelan, and O'Donovan (2006). Variations in population parameters were evaluated for only those studies that Dymond et al. categorized as empirical. Preliminary results indicate that the majority of empirical research in the area of verbal behavior has been conducted with the younger developmentally disabled population and has focused on verbal operants from the introductory chapters of Skinner's book. It is clear that Verbal Behavior has influenced empirical research over the past 50 years. We believe, however, that there are many underdeveloped research areas originating from Verbal Behavior that have not yet been addressed. Suggestions for extended areas of research are provided.

Acquisition of intraverbal behavior: teaching children with autism to mand for answers to questions

Four boys with autism were taught via echoic prompting and constant prompt delay to mand for answers to questions by saying "I don't know please tell me" (IDKPTM). This intervention resulted in acquisition of the IDKPTM response for all 4 participants and in acquisition of correct answers to most of the previously unknown questions for 2 participants. For 1 participant, tangible reinforcement resulted in increased frequency of correct answers, and direct prompting of correct answers was eventually conducted for the final participant. The IDKPTM response generalized to untargeted unknown questions with 3 participants. Results of person and setting generalization probes varied, but some generalization eventually occurred for all participants following additional training or interspersal of probe trials with training trials.

Creating a strategy for progress: a contextual behavioral science approach

Behavior analysis is a field dedicated to the development and application of behavioral principles to the understanding and modification of the psychological actions of organisms. As such, behavior analysis was committed from the beginning to a comprehensive account of behavior, stretching from animal learning to complex human behavior. Despite that lofty goal, basic behavior analysis is having a generally harder time finding academic support, and applied behavior analysis has narrowed its focus. In the present paper we argue that both of these trends relate to the challenge of human language and cognition, and that developments within clinical behavior analysis and the analysis of derived relational responding are providing a way forward. To take full advantage of these developments, however, we argue that behavior analysts need to articulate their unique approach to theory, to develop more flexible language systems for applied workers, and to expand their methodological flexibility. This approach, which we term contextual behavioral science, is meant as an evolutionary step that will allow behavior analysis to better capture the center of modern psychological concerns in both the basic and applied areas. Clinical behavior analysis is showing a way forward for behavior analysis to regain its vision as a comprehensive approach to behavior.

General outcome measures for verbal operants

A general outcome measure (GOM) can be used to show progress towards a long-term goal. GOMs should sample domains of behavior across ages, be sensitive to change over time, be inexpensive and easy to use, and facilitate decision making. Skinner's (1957) analysis of verbal behavior may benefit from the development of GOM. To develop GOM, we conducted a review of the literature on mands, tacts, echoics, and intraverbals. The four areas reviewed included (a) an examination of the participant's response form (i.e., vocal or nonvocal), (b) the type of prompt used, (c) types of materials used, and (d) timing of responses or sessions. Based on the review of the literature, we developed GOM for mands and tacts. This paper attempts to bridge the concept of GOMs with Skinner's analysis of verbal behavior.

Publication trends in the analysis of verbal behavior: 1999-2008

The Analysis of Verbal Behavior (TAVB) publishes experimental and theoretical papers relevant to a behavioral analysis of language. Normand, Fossa, and Poling (2000) reviewed the published studies in TAVB across several dimensions and found that despite the growth of the journal, most articles published in TAVB from 1982 to 1998 were nonexperimental. The current study extends this review by analyzing articles published in TAVB from 1999 through 2008. Results showed that 48% of the articles published between 1999 and 2008 were experimental (65% in the last 4 years), 93% of them used within-subject experimental designs, and most of them (54%) included children with developmental disabilities. This suggests an increased interest in the experimental analysis of verbal behavior with a focus on teaching language to individuals with disabilities.

Relational frame theory: an overview of the controversy

Although Skinner's Verbal Behavior (1957) was published over 50 years ago, behavior-analytic research on human language and cognition has been slow to develop. In recent years, a new behavioral approach to language known as relational frame theory (RFT) has generated considerable attention, research, and debate. The controversy surrounding RFT can be difficult to fully appreciate, partly because of the complexity of the theory itself and partly because the debate has spanned several years and several journals. The current paper aims to provide a concise overview of RFT and a summary of key points of debate and controversy.

A quarter century of the analysis of verbal behavior: an analysis of impact

The Analysis of Verbal Behavior (TAVB) has been published since 1982, and during this time, interest in verbal behavior research appears to have increased substantially within behavior analysis. The purpose of the present analysis was to assess the influence of TAVB on the field by (a) counting citations of TAVB articles in the Journal of the Experimental Analysis of Behavior (JEAB) and the Journal of Applied Behavior Analysis (JABA) from 1983 through 2007, (b) examining which other journals cite TAVB, and (c) calculating impact-factor estimates for 2003 through 2007. Citations of TAVB articles began to appear in JEAB and JABA in the late 1980s to early 1990s, and by the end of 2007, almost a third of all articles published in TAVB had been cited in either JEAB or JABA. Other journals that cite TAVB include The Behavior Analyst and The Psychological Record. The estimated impact factor ranged from 0.267 to 0.600. Strategies for increasing the impact of TAVB are discussed.

An evaluation of intraverbal training to generate socially appropriate responses to novel questions

Four preschool children (with and without disabilities), who often responded inappropriately to questions, participated in the current study. Pretest results were used to create sets of questions that the children either did or did not answer correctly (i.e., known and unknown questions). We then sequentially taught two different responses to a subset of unknown questions: (a) "I don't know" (IDK), and (b) "I don't know, please tell me" (IDKPTM). Results showed that following acquisition with the target set, both responses generalized across questions and teachers for all participants. Following IDK training, some undesirable generalization of IDK to known questions occurred for 3 participants. Training of IDKPTM with the addition of a restricted reinforcement contingency was sufficient to establish correct answers to a portion of previously unknown questions. The importance of teaching generalized responses that enable the acquisition of novel intraverbals is discussed.
