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

Comparing the Effect of Echoic and Listener Responding in the Development of Complex Intraverbals

This study aimed to compare the effects of echoic and listener responding in the emergence of complex intraverbal behavior in four children with autism spectrum disorder (ASD). Each participant was taught to provide an echoic response or a listener response for different discriminative stimuli for each condition. We used a nonconcurrent multiple probe design across participants and adapted an alternating treatment design to compare the effects between the two conditions. Pre- and posttests were used to evaluate the effects of the two different prompt types in the emergence of complex intraverbals. The results indicate that the echoic response was more effective than the listener response at increasing the emergence of complex intraverbal responses in three out of four participants.

A translational evaluation of component skills for the establishment of multiply controlled intraverbals

Intraverbal behavior is a type of verbal behavior in which the response form has no point-to-point correspondence with its verbal stimulus. However, the form and occurrence of most intraverbals is under the control of multiple variables. Establishing this form of multiple control may depend on a variety of preestablished skills. The purpose of Experiment 1 was to evaluate these potential prerequisites with adult participants using a multiple probe design. The results suggest that training was not required for each putative prerequisite. In Experiment 2, probes for all skills were conducted following convergent intraverbal probes. The results showed that convergent intraverbals only emerged when proficiency of each skill was demonstrated. Finally, Experiment 3 evaluated alternating training of multiple tact and intraverbal categorization. The results showed that this procedure was effective for half of the participants.

Integrative Review of Developmental Behavior-Analytic Concepts

We reviewed five behavior-analytic concepts related to development: behavioral trap, cumulative-hierarchical learning (CHL), basic behavioral repertoire (BBR), pivotal behavior, and behavioral cusp. We searched for terminological variations of the concepts in the CAPES Journals Portal and selected for analysis 31 peer-reviewed articles written in English or Portuguese, published between 1967 and 2021, that contained the search terms in the title, abstract, or keywords and contextualized in the main text. We analysed the conventional usage of the concepts, their conceptual limitations, and the relationships among them, declared or implied, and proposed a conceptual integration of the concepts under a CHL framework, following a path indicated by other authors. We considered BBR, pivotal behavior, and behavioral cusp nonsynonymous concepts of the same logical category, referring to prerequisites for important developmental outcomes and targets of CHL-inspired interventions but defined by different effects on subsequent behavioral development. The three concepts can be conflated in a superset-subset fashion, based on the specificity of their effects: BBR consists of a broad class of behaviors that may affect subsequent learning; the subclass of BBRs characterized by far-reaching collateral effects are classified as pivotal behavior, and the subclass of pivotal behaviors whose potential effects include contact with unprecedented environmental contingencies are classified as behavioral cusps. We propose that behavioral traps be explicitly incorporated in the CHL framework, to emphasize the environmental component of the cumulative-hierarchical learning process. Our formulation seems to organize the conceptual field in a way that respects the conventional use of concepts, preserving their strengths. Regardless of the specific formulation, we believe that integrating the various development-related concepts within a cumulative-hierarchical learning framework can encourage a more proactive integration of findings, questions, and practices informed by each concept, which could lead to the mutual refinement of the corresponding conceptual and methodological frameworks, as well as new research questions and practical applications. In particular, we expect that explicitly incorporating behavioral traps within the CHL framework will provide a useful heuristic model to guide research on how natural environmental contingencies influence the systematic transformation of behavior across the lifespan.

The Effects of Tact Training on Echolalia in Children with Autism Spectrum Disorder in China

Echolalia can negatively impact multiple skill areas in children diagnosed with autism spectrum disorder (ASD), including skills related to academic and social performance. The purpose of this study was to employ a multiple probe across participants design to evaluate the effects of tact training on delayed echolalia in three children in China diagnosed with ASD. The results of this study indicated that tact training was effective in decreasing echolalia and increasing appropriate tacts for all three children. The effects were maintained 7 weeks following the completion of training.

Learning Channels: The Role of Compound Stimuli in the Emergence of Intraverbal Relations in Children on the Autism Spectrum

Teaching tact and intraverbal responses based on function-feature-class to children with language delays can result in the emergence of untrained relational responses. The purpose of this study was to compare the effects of compound stimuli in discriminated operants (i.e., different combinations of hear, see, touch, and taste) on the acquisition of object-attribute relations, on the emergence of untrained attribute-object relations, and on the acquisition and emergence of same-different relations between objects and their attributes. All the participants were on the autism spectrum and between 4 and 12 years old. Participants who did not meet the mastery criterion or show emergent intraverbal responses during initial training trials completed a fluency-based practice phase. Overall results showed that all six participants required fewer trials to meet the criterion in the condition involving compound stimuli (e.g., HearSeeSay plus Touch, Taste, or Sniff) as compared to the HearSeeSay-alone condition. In addition, participants required fewer fluency practice timings in the condition involving compound stimuli to meet fluency aim.

Teaching children with autism to mand for social information

We replicated Shillingsburg et al. (2018) by teaching children with autism to mand for social information while analyzing the variables influencing the emission of mands. We presented questions about a social partner that were known and observable (e.g., "What is Robin doing?"), known but unobservable (i.e., questions for which an intraverbal response had previously been taught, such as, "Where does Robin work?"), or unknown (e.g., "What is Robin's favorite food?"). Correct answers were reinforced across all conditions. During treatment, we prompted children to mand for information from the social partner following only unknown questions. All children acquired mands for social information and answered previously unknown questions correctly after manding for social information and 3 of 4 participants emitted mands to novel social partners, including a peer with autism.

Effects of exposure to prompts on the acquisition of intraverbals in children with autism spectrum disorder

The current experiment is a systematic replication of previous studies that evaluated the efficiency of echoic and tact prompts on the acquisition of intraverbals (i.e., French-to-English translations) following exposure to each prompt type. We extended these studies by (a) evaluating participants' language skills on standardized assessments, (b) incorporating descriptive praise for correct responding, (c) presenting trials via voice recording, and (d) evaluating teacher preference for each prompt type as a social validity measure. All participants learned at least one set of intraverbals faster with the procedure that was most recently used during teaching. These findings suggest that results from previous prompt comparison studies might be a function of previous exposure to prompt types and that it might be possible to manipulate learning histories such that a particular prompt type becomes more efficient.

Exposure to a specific prompt topography predicts its relative efficiency when teaching intraverbal behavior to children with autism spectrum disorder

Comparisons of the relative efficiency of different prompt topographies (visual or auditory), when teaching intraverbal behavior to children with disabilities, have yielded idiosyncratic results. Recent research has shown that previous exposure to a specific prompt type may affect its efficiency when teaching intraverbal behavior to preschool children. The current study was an attempt to replicate these results with 3 children diagnosed with autism spectrum disorder. For all participants, increased exposure to one prompt topography was sufficient to make it relatively more efficient as measured by number of trials to criterion. These results suggest that previous history with a prompt type may predict its efficiency.

Teaching Children with Autism Extended Verbal Utterances Under Audience Control in the Context of Show-and-Tell

The present study evaluated the efficacy of a discrete-trial-training procedure to bring extended verbal behavior under the convergent control of audience and contextual variables during a show-and-tell activity. Three children with autism were exposed initially to a baseline condition in which they were presented with a preferred item and asked to tell the class about it. Following low rates of responding, a differential reinforcement procedure was implemented that reinforced extending the verbal utterance word length beyond baseline levels allowing for an appropriate display of "show-and-tell" behavior. The results show that the procedures were efficacious in application with three children with autism, providing a method that can be conducted in classroom settings to teach a complex form of verbal operant behavior.

Observational learning and children with autism: discrimination training of known and unknown stimuli

We extended past observational learning research by incorporating stimuli already known to participants into training. We used a multiple-baseline design across three participants to determine the effects of discrimination training on the discrimination of consequences applied to modeled responses using both known and unknown pictures. During baseline, participants were exposed to modeled correct and incorrect picture labels and were observed to imitate modeled responses that were incorrect and followed by negative feedback. During discrimination training, we taught participants to label known pictures regardless of observed responses and consequences. With unknown pictures, we taught participants to imitate correct and reinforced modeled responses, and to say, "I don't know," when modeled responses were incorrect and received negative feedback. Test sessions measured responding to known and unknown pictures and showed acquisition over baseline levels. Generalization to pictures not associated with training was variable. Implications for teaching observational learning to children with autism are discussed.

Empirical Investigations of the Intraverbal: 2005-2015

Several papers have reviewed the literature based on Skinner's conceptual framework presented in his 1957 book, Verbal Behavior. These reviews have called for more research on the topic of verbal behavior generally and often for more research on particular verbal operants. For example, Sautter and LeBlanc (2006) urged the behavior-analytic community to conduct more research on the intraverbal because of the scant existing literature base at that time. In the current review, we replicate the procedures used by Sautter and LeBlanc focusing specifically on the intraverbal relation and on the literature published in the 10 years since their call for research. We summarize the publication themes, provide graphs of the trends and types of published articles, and offer ideas for future research specific to the intraverbal.

Verbal Stimulus Control and the Intraverbal Relation

The importance of the intraverbal relation is missed in most theories of language. Skinner (1957) attributes this to traditional semantic theories of meaning that focus on the nonverbal referents of words and neglect verbal stimuli as separate sources of control for linguistic behavior. An analysis of verbal stimulus control is presented, along with its distinction from nonverbal stimulus control and motivational control. It is suggested that there are at least four different types of increasingly complex verbal discriminations relevant to speaker and listener behavior: simple, compound, verbal conditional, and verbal function-altering (Eikeseth & Smith, 2013; Schlinger & Blakely, 1994). Separate but interlocking accounts of how these specific types of verbal stimuli produce different evocative and function-altering effects for the speaker and for the listener are provided. Finally, the effects of weakening verbal stimulus control and the loss of intraverbal behavior are considered, especially as they relate to dementia, aphasia, and traumatic brain injury.

Teaching a Child with Autism to Mand for Answers to Questions Using a Speech-Generating Device

The current study systematically replicates and extends the findings of Ingvarsson and Hollobaugh (2010) by teaching a boy with autism who used a speech-generating device to mand for answers to unknown questions. The effects of the intervention were evaluated via a multiple baseline across stimulus sets. The intervention resulted in acquisition of both the mand for information and intraverbal responses (i.e., correct answers to previously unknown questions). However, generalization of the mand for information was limited.

Contingency analysis of caregiver behavior: Implications for parent training and future directions

Parent training is often a required component of effective treatment for a variety of common childhood problems. Although behavior analysts have developed several effective parent-training technologies, we know little about the contingencies that affect parent behavior. Child behavior is one source of control for parent behavior that likely contributes to the development of childhood problems and outcomes of parent training. We reviewed the evidence supporting child behavior as controlling antecedents and consequences for parent behavior. The implications for parent training are discussed, and recommendations for future research are suggested.

The role of increased exposure to transfer-of-stimulus-control procedures on the acquisition of intraverbal behavior

Studies that have compared the effectiveness of differing prompt types to teach intraverbal responses have yielded mixed results, suggesting that individuals' reinforcement histories with prompt types may influence which prompt will be most effective. The purpose of this study was to test whether programmed increases in exposure to specific prompt types would produce concomitant increases in the acquisition rate of intraverbal responding. We compared acquisition rates among 4 typically developing preschool-aged children when taught via either echoic or tact prompts following exposure training with 1 prompt type. For all participants, the prompt method most recently used to teach intraverbal responses required fewer trials to teach new intraverbal responses compared to a prompt method that had not been used recently. The results are discussed in terms of the effects of reinforcement history on the acquisition of verbal behavior.

An analysis of verbal stimulus control in intraverbal behavior: implications for practice and applied research

A common characteristic of the language deficits experienced by children with autism (and other developmental disorders) is their failure to acquire a complex intraverbal repertoire. The difficulties with learning intraverbal behaviors may, in part, be related to the fact that the stimulus control for such behaviors usually involves highly complex verbal stimuli. The antecedent verbal control of intraverbal behavior may involve discriminative stimuli (i.e., discriminated operants), conditional stimulus control, and/or control by compound stimuli. Distinctions among these different types of antecedent control are presented, along with recommendations for intervention procedures that may facilitate the acquisition of intraverbal behavior.

What is evidence-based behavior analysis?

Although applied behavior analysts often say they engage in evidence-based practice, they express differing views on what constitutes "evidence" and "practice." This article describes a practice as a service offered by a provider to help solve a problem presented by a consumer. Solving most problems (e.g., increasing or decreasing a behavior and maintaining this change) requires multiple intervention procedures (i.e., a package). Single-subject studies are invaluable in investigating individual procedures, but researchers still need to integrate the procedures into a package. The package must be standardized enough for independent providers to replicate yet flexible enough to allow individualization; intervention manuals are the primary technology for achieving this balance. To test whether the package is effective in solving consumers' problems, researchers must evaluate outcomes of the package as a whole, usually in group studies such as randomized controlled trials. From this perspective, establishing an evidence-based practice involves more than analyzing the effects of discrete intervention procedures on behavior; it requires synthesizing information so as to offer thorough solutions to problems. Recognizing the need for synthesis offers behavior analysts many promising opportunities to build on their existing research to increase the quality and quantity of evidence-based practices.

Further evaluation of prompting tactics for establishing intraverbal responding in children with autism

We compared prompting tactics to establish intraverbal responding (question answering) in four boys with autism. Based on the results of intraverbal, textual, echoic, and tact pretests, we compared vocal and picture prompts with three participants, and textual, vocal, and picture prompts with one participant. We also evaluated repeated acquisition with different question sets, and included a concurrent-chains arrangement, in which initial link selections determined which prompting procedure occurred in the terminal link. All the prompting procedures were effective in establishing intraverbal responding, but vocal prompts resulted in the fewest trials to criterion for all four participants during the initial prompt comparison. However, the results were less consistent for the second comparison. The concurrent chains arrangement revealed a clear preference for picture prompts for one participant, but the results for the others were inconclusive.

Intraverbal behavior and verbal conditional discriminations in typically developing children and children with autism

Individuals with autism often experience difficulty acquiring a functional intraverbal repertoire, despite demonstrating strong mand, tact, and listener skills. This learning problem may be related to the fact that the primary antecedent variable for most intraverbal behavior involves a type of multiple control identified as a verbal conditional discrimination (VC(D)). The current study is a descriptive analysis that sought to determine if there is a general sequence of intraverbal acquisition by typically developing children and for children with autism, and if this sequence could be used as a framework for intraverbal assessment and intervention. Thirty-nine typically developing children and 71 children with autism were administered an 80-item intraverbal subtest that contained increasingly difficult intraverbal questions and VC(D)s. For the typically developing children the results showed that there was a correlation between age and correct intraverbal responses. However, there was variability in the scores of children who were the same age. An error analysis revealed that compound VC(D)s were the primary cause of errors. Children with autism made the same types of errors as typically developing children who scored at their level on the subtest. These data suggest a potential framework and sequence for intraverbal assessment and intervention.

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.

Behavior analysis and ecological psychology: past, present, and future. a review of Harry Heft's Ecological Psychology in context

Relations between behavior analysis and ecological psychology have been strained for years, notwithstanding the occasional comment on their affinities. Harry Heft's (2001)Ecological Psychology in Context provides an occasion for reviewing anew those relations and affinities. It describes the genesis of ecological psychology in James's radical empiricism; addresses Holt's neorealism and Gestalt psychology; and synthesizes Gibson's ecological psychology and Barker's ecobehavioral science as a means for understanding everyday human behavior. Although behavior analysis is excluded from this account, Heft's book warrants a review nonetheless: It describes ecological psychology in ways that are congruent and complementary with behavior analysis (e.g., nonmediational theorizing; the provinces of natural history and natural science). After introducing modern ecological psychology, I comment on (a) Heft's admirable, albeit selective, historiography; (b) his ecological psychology-past and present-as it relates to Skinner's science and system (e.g., affordances, molar behavior); (c) his misunderstandings of Skinner's behaviorism (e.g., reductionistic, mechanistic, molecular); and (d) the theoretical status of Heft's cognitive terms and talk (i.e., in ontology, epistemology, syntax). I conclude by considering the alliance and integration of ecological psychology and behavior analysis, and their implications for unifying and transforming psychology as a life science, albeit more for the future than at present.

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.

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.
