Emergence of Naming Relations and Intraverbals After Auditory Stimulus Pairing

Naming: What Do We Know So Far? A Systematic Review

Although the term naming is used colloquially in the English language, it refers to a specific instance of verbal behavior within behavior analysis. Since Horne and Lowe's (Horne & Lowe, 1996) seminal account on naming, the concept continues to generate clinical and research interest to-date. We conducted a systematic search of the behavior analytic studies on naming to highlight the methods that were used to test naming, the terminology that have been adopted, the conceptual underpinnings, and the methods used to train naming if it was found to be absent. Forty-six studies met inclusion criteria and we conducted a descriptive analysis of these studies. We found that most studies either used the terms naming or bidirectional naming. We found wide variation in the methods used to test and train naming. Nearly one third of these studies attempted to offer evidence that naming facilitated some other type of behavior, and the remaining studies attempted to train naming in individuals when the behavior was found to be absent. Overall, our review highlighted that there exists a rich empirical dataset on testing and training naming within behavior analysis, and we discussed specific areas for future research.

Learning Symmetrical Relations Facilitates Emergence of Intraverbals after Reading a Text: Effects on Reading Comprehension

We studied the effect of prior learning of symmetrical intraverbals on the emergence of complex intraverbals after reading a text. In Experiment 1, eighteen 7- and 8-year-old children read a text with sentences in which A and B stimuli and B and C stimuli were related (e.g., “The Alps” to “Mont Blanc,” and to “Falcon”). Thereafter, all ABC intraverbals (e.g., C–A—“Name the mountain range of the falcon”) were probed without reinforcement with written stimuli and written responses. In Condition 1, six children learned before intraverbals that relate the categories to the exemplars that served as stimuli in the text (e.g., “Name a mountain”—“Mont Blanc”—Exemplars) and learned intraverbals that relate the exemplars to the categories (e.g., “What is the Mont Blanc?”—“A mountain”—Categories.) In Conditions 2 and 3, 12 children did not learn Categories or neither Exemplars and Categories. All children in Condition 1 demonstrated the emergence of all ABC intraverbals, but not all children in Conditions 2–3 demonstrated emergence. Experiment 2 controlled that text presentations and teaching trials did not affect the results and replicated the effect. Therefore, learning simple discriminations symmetrical to one another facilitates further emergence with more complex discriminations—intraverbals—which evidence reading comprehension.

Training sequence effects on emergent conditional discriminations: Replication and extension to selection-based training

We examined the replicability and generality of a previously reported training sequence effect on emergent conditional discriminations in the intraverbal naming task. In Experiment 1, a tact-intraverbal (TI) group learned first to vocally label 6 visual patterns and then to intraverbally relate pairs of verbal labels, whereas an intraverbal-tact (IT) group received the same training in the opposite sequence. Emergent conditional discriminations among pattern stimuli were assessed in match-to-sample (MTS) format. Experiment 2 was identical, except vocal tact and intraverbal training were replaced with selection-based training in which the verbal labels were text stimuli. Compared to the IT sequence, the TI sequence resulted in greater mean accuracy at test (Experiment 1), higher yields (Experiment 2), and shorter reaction times (Experiment 2). Experiment 2 data suggested the TI group's performance might be less dependent on intact intraverbal relations relative to the IT group, but related to participants' reports of visualization during intraverbal training. The results suggest the sequence effect is replicable and occurs in experimental preparations commonly used to study derived stimulus relations. They also provide novel support for the hypothesis that participant behavior during training alters sources of stimulus control available at test.

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.

Verbal Development, Behavioral Metamorphosis, and the Evolution of Language

Building on Skinner's theory of verbal behavior, research over the last few decades confirmed verbal speaker operants, added the role of the listener, added the identification of speaker and listener interaction between and within individuals, and identified verbal behavior developmental cusps. Meanwhile, comparative biology focused on how and why language evolved in Homo sapiens. Findings about differences in behavior that neurotypical children demonstrated in their verbal development, and even more so in research that identified and established missing verbal behavior cusps, suggested changes analogous to metamorphosis. These striking changes in stimulus control found in the onset of cusps from the preverbal to the fully verbal child led us to an expansion of the concept of metamorphosis from morphology to the domain of behavior. The major findings of this comparative perspective are presented here as they have led us from experimental analyses of verbal development to metamorphosis as complex verbal behavior transformation and finally to a novel hypothesis about the evolution of language based on the concepts and research described here. To our knowledge, this is the first formulation of verbal development as behavioral metamorphosis in the context of evolutionary developmental biology.

Aquisição de intraverbais em crianças com autismo: efeitos do pareamento de estímulos e respostas ecoicas

Resumo O ensino de intraverbais para indivíduos com autismo tem sido realizado, principalmente, através de procedimentos que envolvem reforçamento diferencial. Recentemente, o procedimento de observação de pareamento de estímulos (SPOP) surgiu enquanto alternativa para verificar a emergência de repertórios verbais. O SPOP implica o pareamento de estímulos sem exigir outra resposta que a observação do pareamento. O ecoico tem sido apontado como facilitador na emergência de operantes verbais. O presente estudo comparou, com um delineamento de sondas múltiplas concorrentes com tratamento alternado adaptado, a eficácia do SPOP com um procedimento de apresentação contígua de estímulos com requisição de resposta ecoica na emergência de intraverbais em três crianças com autismo. Observou-se a eficácia do SPOP na indução de intraverbais e verificou-se o papel facilitador do ecoico. Discutem-se possíveis efeitos de interferência dos tratamentos, da extinção de respostas no contexto experimental e da utilização de reforçadores condicionados como parte do SPOP.

Common and Intraverbal Bidirectional Naming

Naming has been defined as a generalized operant that combines speaker and listener behaviors within the individual. The purpose of this paper is to reintroduce the concept of naming and its subtypes, common and intraverbal, distinguish it from other terms such as the tact relation, and discuss the role of naming in the development of verbal behavior. Moreover, a taxonomical change is proposed. The addition of the qualifier bidirectional would serve to emphasize the speaker-listener bidirectional relation and serve to distinguish the technical term from its commonsense use. It is hoped that this paper will inspire future basic and applied research on an important extension of Skinner's analysis of verbal behavior.
