The Emergence of the Listener to Speaker Component of Naming in Children as a Function of Multiple Exemplar Instruction

We tested the effect of multiple exemplar instruction on the transfer of stimulus function for unfamiliar pictures across listener responses (i.e., matching and pointing) and speaker responses (i.e., pure tacts and impure tacts). Three preschool students, who were 3- and 4-year-old males and did not have the listener to speaker component of the naming repertoire, participated in the experiment. The dependent variable was numbers of correct responses to probe trials of both untaught listener responses (“point to__”) and speaker responses (tact and impure tacts) following mastery of matching responses for two sets of five unfamiliar pictures (Set 1 and Set 3). After each participant mastered matching (e.g., “match Labrador”) for Set 1 pictures they were probed on the three untaught responses to Set 1 words. That is, they were asked to point to Labrador, tact the picture of Labrador, and respond to the picture of a Labrador and the question “What is this?” Next, the participants were taught mastery of all four types of responses using MEI for a second set of five pictures (Set 2) and probed again on the 3 untaught Set 1 responses. Finally, matching responses were taught to mastery for a novel set of pictures (Set 3) and then probed on the three untaught responses. The results showed that untaught speaker responses emerged at 60% to 85% for two participants, and 40%–70% for one participant. We discuss the role of instructional history in the development of the listener to speaker component of naming.     

Multiple exemplar instruction and the emergence of generative production of suffixes as autoclitic frames

We report 2 experiments that tested the effects of multiple exemplar instruction (MEI) across training sets on the emergence of productive autoclitic frames (suffixes) for 6 preschoolers with and without language-based disabilities. We implemented multiple exemplar tact instruction with subsets of stimuli whose "names" contained the suffix "-er" denoting the comparative form of adjectives. Subsets of stimuli included regular, irregular, and contrived tacts containing the target relational autoclitic frame in order to determine if our MEI procedure would induce the abstraction of the frame across all stimulus sets. In the second experiment, additional tasks were introduced to the participants to control for a possible sequence effect. A nonconcurrent multiple probe design was used to evaluate the functional relation between MEI and emergence of untaught tact responses containing the comparative adjective "-er." The results of both experiments showed relations between MEI and novel, untaught tact responses containing the target autoclitic frame; the second experiment showing a functional relation. The results are discussed in terms of environmental sources for productive verbal behavior.     

Novel Dictation and Intraverbal Responses as a Function of a Multiple Exemplar Instructional History

We tested the effect of multiple exemplar instruction (MEI) on acquisition of joint spelling responses, vocal to written and vice versa, for three sets of five words by four kindergarteners with language delays using a delayed multiple probe design. First, students were taught to spell Set 1 as either vocal or written responses (two vocal and two written) and probed on untaught responses. Next students were taught Set 2 using MEI (i.e., alternating responses) and again probed untaught responses for Set 1. Finally, Set 3 was taught in a single response and students were probed on untaught responses. Two students spelled none of Set 1 untaught responses before MEI, while two spelled the words at 60% accuracy or 10% accuracy. After MEI on Set 2, all students spelled untaught responses for Set 1 at 80% to 100% accuracy and Set 3 at 80% to 100% accuracy. The MEI resulted in joint stimulus function such that formerly independent responses came under the same stimulus control. We replicated these results with four other kindergartners with autism who performed academically above their typically developing peers. The results are discussed in terms of Skinner''s treatment of the independence of the two verbal operants.     

The Emergence of Autoclitic Frames in Atypically and Typically Developing Children as a Function of Multiple Exemplar Instruction

In two experiments, we tested the effect of multiple exemplar instruction (MEI) for training sets on the emergence of autoclitic frames for spatial relations for novel tacts and mands. In Experiment 1, we used a replicated pre- and post-intervention probe design with four students with significant learning disabilities to test for acquisition of four autoclitic frames with novel tacts and mands before and after MEI. The untaught topographies emerged for all participants. In Experiment 2, we used a multiple probe design to test the effects of the MEI procedures on the same responses in four typically developing, bilingual students. The novel usage emerged for all participants. In the latter experiment, the children demonstrated untaught usage of mand or tact frames regardless of whether they were taught to respond in either listener or speaker functions alone or across listener and speaker functions. The findings are discussed in terms of the role of MEI in the formation of abstractions.     

Establishing Naming in Typically Developing Two-Year-Old Children as a Function of Multiple Exemplar Speaker and Listener Experiences

Naming is a verbal developmental capability and cusp that allows children to acquire listener and speaker functions without direct instruction (e.g., incidental learning of words for objects). We screened 19 typically developing 2- and 3-year-old children for the presence of Naming for 3-dimensional objects. All 9 3-year-olds had Naming, and 8 of 10 2-year-olds lacked Naming. For the 2-year-old children who lacked Naming, we used multiple-probe designs (2 groups of 4 children) to test the effect of multiple exemplar instruction (MEI) across speaker and listener responses on the emergence of Naming. Prior to the MEI, the children could not emit untaught listener or speaker responses following match-to-sample instruction with novel stimuli, during which they had heard the experimenter tact the stimuli. After MEI with a different set of novel stimuli, the children emitted listener and speaker responses when probed with the original stimuli, in the absence of any further instruction with those stimuli. Seven of 8 children acquired the speaker and listener responses of Naming at 83% to 100% accuracy. We discuss the basic and applied science implications.     

The Effects of Multiple Exemplar Instruction on the Relation Between Listener and Intraverbal Categorization Repertoires

We evaluated the effects of multiple exemplar instruction (MEI) on the relation between listener and intraverbal categorization repertoires of six typically developing preschool-age children using a nonconcurrent multiple-probe design across participants. After failing to emit intraverbal categorization responses following listener categorization training, participants were exposed to MEI in the form of alternating response forms (listener and intraverbal) during categorization training with novel stimulus sets. For two participants for whom there was some evidence of emergent intraverbal responding, responding was variable. For the remaining four participants, 32 to 99 MEI trial blocks produced minimal improvement in responding or no emergent responding at all. The results are discussed in terms of Skinner’s analysis of verbal behavior and naming theory.     

Mands for Information Using “How” Under EO-Absent and EO-Present Conditions

The present study replicates and extends previous research on teaching “How?” mands for information to children with autism. The experimental preparation involved mand training in the context of completing preferred activities and included training and testing under conditions when the establishing operation (EO) was present and absent. Results show that two children with autism acquired mands for information using How? only in situations where information was valuable (i.e., the EO was present); they then consistently made use of the information provided in activity completion. Generalization to novel, untaught situations was assessed.     

Effects of Multiple Exemplar Training on the Emergence of Derived Relations in Preschool Children Learning a Second Language

We evaluated the facilitative effects of multiple exemplar training (MET) on the establishment of derived tact relations in typically developing children. A multiple-probe design across stimulus sets was implemented to introduce MET. Participants were first taught to conditionally relate dictated names in English to their corresponding objects (listener behavior; A-B relations), followed by tests for derived tacts (B-A relations). If participants failed these tests, MET was implemented whereby tact relations were explicitly taught with novel stimulus sets, followed by test probes with the original training set. MET continued with novel stimuli until participants met criterion for the emergence of derived tact relations or after exposure to three MET sets. Results indicated failed tests for tact relations following direct training in listener relations, and marked improvements in derived tact relations following MET across all participants.     

Does ABLA Test Performance on the ABLA Test Predict Picture Receptive Name Recognition with Persons with Severe Developmental Disabilities?

Research has shown that performance on the Assessment of Basic Learning Abilities (ABLA) test correlates with language assessments for persons with developmental disabilities. This study investigated whether performance on ABLA Level 6, an auditory-visual discrimination, predicts performance on a receptive language task with persons with severe developmental disabilities. Five participants who passed ABLA Level 6, and five who failed ABLA Level 6, were each tested on five 2-choice discriminations that required them to point to pictures of common objects after hearing their names. Four of the five participants who had failed ABLA Level 6 failed all of the receptive name recognition tasks. All five participants who had passed ABLA Level 6 passed all of the name recognition tasks. The practical implications of these results are discussed.

Rudimentary Reading Repertoires via Stimulus Equivalence and Recombination of Minimal Verbal Units

We report a study with sixteen low-SES Brazilian children that sought to establish a repertoire of relations involving dictated words, printed words, and corresponding pictures. Children were taught: (1) in response to dictated words, to select corresponding pictures; (2) in response to syllables presented in both visual and auditory formats, to select words which contained a corresponding syllable in either the first or the last position; (3) in response to dictated-word samples, to “construct” corresponding printed words via arranging their constituent syllabic components; and (4) in response to printed word samples, to construct identical printed words by arranging their syllabic constituents. After training on the first two types of tasks, children were given tests for potentially emergent relations involving printed words and pictures. Almost all exhibited relations consistent with stimulus equivalence. They also displayed emergent naming performances––not only with training words but also with new words that were recombinations of their constituent syllables. The present work was inspired by Sidman''s stimulus equivalence paradigm and by Skinner''s functional analysis of verbal relations, particularly as applied to conceptions of minimal behavioral units and creativity (i.e., behavioral flexibility) in the analytical units applied to verbal relations.     

The Use of Instructive Feedback to Promote Emergent Tact and Intraverbal Control: A Replication

Instructive feedback (IF) involves incorporating additional acquisition targets into skill-acquisition programs. A recent study by Frampton and Shillingsburg (2020) found that IF led to emergent verbal operants with two elementary-aged children diagnosed with autism spectrum disorder (ASD). The current study replicated Frampton and Shillingsburg with two children with ASD. Therapists conducted sessions of mastered listener-by-name trials (e.g., “Show me otter,” with pictures of otter, dog, and elephant) with IF statements for features of the target stimuli (e.g., “It lives in rivers.”) embedded during the consequence portion of the trial. We evaluated the acquisition of secondary targets and emergent responses using a concurrent multiple baseline across sets design. We observed increased correct responding for secondary targets and emergent responses for all three sets of stimuli with one participant. The other participant emitted correct responses for secondary targets and emergent operants with the first set but not with the other two sets of stimuli. Results suggested that IF can lead to emergent verbal operants, but the extent of emergence may be idiosyncratic.Supplementary InformationThe online version contains supplementary material available at 10.1007/s40616-022-00171-y.     

Is a Reasonable Attempt Reasonable? Shaping Versus Reinforcing Verbal Attempts of Preschoolers with Autism

The effectiveness of a language-training procedure that emphasized reinforcing vocal “reasonable attempts” (any response directed at an interventionist and within a broader class of correct responses) was compared with a procedure that emphasized shaping (reinforcing successive approximations that more closely resembled the target vocalization). Three preschoolers who had been diagnosed with autism spectrum disorders participated in the study. Data indicated that the children mastered vocal skills more rapidly when they learned through shaping than in the reasonable attempts condition. Implications for teaching children with autism spectrum disorders are discussed.     

Evaluating the Emergence of Reverse Intraverbals in Children with Autism

Verbal behavior plays a fundamental role in the development of complex social and communication skills. Many children diagnosed with autism spectrum disorder exhibit profound deficiencies in intraverbal repertoires and the development of social relationships. Recent studies that investigated the effects of intraverbal training on the emergence of reverse intraverbals produced mixed results (e.g., Perez-Gonzalez et al., Journal of Applied Behavior Analysis 40:697–701, 2007)). In the current study, a multiple-probe design across four participants with autism was used to evaluate the effects of intraverbal training on the emergence of reverse intraverbals. Intraverbal training consisted of multiple exemplars taught concurrently, bidirectional stimulus-response teaching formats, general case analysis, reinforcement, and a constant prompt delay (CPD) procedure. Participants were trained on intraverbal targets and probes were conducted to assess emergence of untaught reverse intraverbals. Three participants demonstrated the emergence of reverse intraverbals as a result of the intraverbal training procedures. Social validity and maintenance of target responses and emergent reverse intraverbals were assessed.     

The Use of Internet Chat Rooms to Meet Sexual Partners: A Comparison of Non-Heterosexually Identified Men with Heterosexually Identified Men and Women

ABSTRACT. Objectives: Prior work suggests that many individuals use the Internet to meet romantic or sexual partners. Our intent was to explore perceptions and experiences with meeting people online. Methods: In 2008, the authors conducted U.S.-based online interviews with 65 predominantly White, self-identified heterosexual men and women and gay/bisexual men (Mean age = 30.8 years). Results: Reasons for meeting people online, desired partner characteristics, and the process of connecting for sex paralleled those observed in face-to-face contexts. People used Internet chat rooms to identify more partners and specific partner characteristics. “Background checks” of online partners, though often believed to be inaccurate, increased familiarity and trust leading to reduced condom use. Participants said online condom use negotiation was easier but usually occurred in face-to-face contexts. Conclusions: The fundamental processes of meeting partners online are similar in many ways to meeting partners face-to-face; however, the Internet facilitates rapid access to relatively large numbers of potential partners.     

Joint Control: A Discussion of Recent Research

The discrimination of the onset of joint control is an important interpretive tool in explaining matching behavior and other complex phenomena, but the difficulty of getting experimental control of all relevant variables stands in the way of a definitive experiment. The studies in the present issue of The Analysis of Verbal Behavior illustrate how modest experiments can take their place in a web of interpretation to make a strong case that joint control is a necessary element of such phenomena.     

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.     

Toward an “Awareness” of the Relationship between Task Performance and Own Verbal Accounts of that Performance

The existence of learning without awareness has been debated for many years. Learning without awareness is said to occur when an individual''s behavior has been affected without that individual being aware of the conditions affecting the behavior, of the relationship between those conditions and the behavior, or of the fact that the behavior has changed. This paper describes a series of experiments investigating this phenomenon. The findings support the existence of “learning without awareness.” However, it is argued that the term “awareness” should be discarded as it is misleading. Instead, the results of the experiments are discussed in terms of behavior for which the individual does not provide a complete verbal account.     

Recombinative Generalization of Tacts Through Matrix Training with Individuals with Autism Spectrum Disorder

Foss (Journal of Experimental Psychology, 76, 450–459, 1968a; Journal of Experimental Psychology, 77, 341–344, 1968b) compared overlap and non-overlap instruction to promote recombinative response generalization using a matrix training procedure. In the present study, we used a similar set of procedures to teach tacting of kitchen items and prepositions (i.e., relational autoclitics) to three females ages 13–20, diagnosed with autism spectrum disorder. We taught some kitchen items/prepositions as tacts (e.g., “the strainer is to the right of the box”) according to a non-overlap instructional sequence. Subsequently, we taught more combinations in an overlap instructional sequence. Each training procedure was followed by probes of untrained relations. Two participants demonstrated recombinative generalization of untrained combinations following the first non-overlap phase, while the third participant demonstrated some response generalization of untrained relations after a few additional training sequences. All three participants demonstrated generalized tacting of object components while two participants showed generalized tacting of preposition components.     

The Use of the NICHD Protocol to Enhance the Quantity of Details Obtained from Children with Low Verbal Abilities in Investigative Interviews: A Pilot Study

ABSTRACT

This study explored the impact of the NICHD protocol to enhance the quantity and content of details reported by children with low verbal abilities. Thirty-four children aged from 6 to 14 were interviewed following their experience of sexual abuse. Half the interviews were conducted using the NICHD protocol. Results indicate that NICHD interviews contained more open-ended prompts and more details overall. Open-ended invitations yielded significantly more detailed responses than did closed-ended questions for both children with low and average verbal abilities. Although children with low verbal abilities provided fewer details than children with average verbal abilities, the NICHD protocol helped them provide detailed responses containing the core elements of the sexual abuse.
