Emergent Intraverbal and Reverse Intraverbal Behavior Following Listener Training in Children with Autism Spectrum Disorder

We evaluated whether intraverbal and reverse intraverbal behavior emerged following listener training in children with autism spectrum disorder (ASD). Six participants were each taught three sets of three “when?” questions in listener training. A multiple baseline design across behaviors (stimulus sets) was used to assess the effects of listener training. Results showed that intraverbal behavior emerged following listener training for five out of six participants. One participant received additional listener training and intraverbal training before intraverbal behavior emerged. Furthermore, reverse intraverbal responding occurred across all three sets of questions for three of the six participants. Establishing listener behavior may be a pathway for emergent intraverbal and reverse intraverbal responding in children with ASD. Future research could examine what skill repertoire may facilitate such transfer.     

Emergent Intraverbal Forms may Occur as a Result of Listener Training for Children with Autism

The purpose of the present study was to assess whether intraverbal behavior, in the form of answers to questions, emerges as a result of listener training for five children diagnosed with autism. Listener responses were targeted and taught using prompting and differential reinforcement. Following successful acquisition of listener responses, the intraverbal form of the response was probed. Data were evaluated via a nonconcurrent multiple-baseline design that included a control series. Results showed listener-to-intraverbal transfer for four of the five participants. One participant required additional teaching that involved tacting the items selected during listener training.

     

Using Instructive Feedback to Increase Response Variability During Intraverbal Training for Children with Autism Spectrum Disorder

We evaluated the effects of instructive feedback on the variability of intraverbal responses for two children with autism spectrum disorder. Specifically, we used an adapted alternating treatments design to compare participants’ novel responses and response combinations during an intraverbal category program across conditions with and without instructive feedback. During instructive feedback, secondary targets were presented during the consequence event of the learning trial and consisted of a therapist’s model of response variability. The results showed that participants engaged in more novel response combinations during instructive feedback conditions. We discussed the clinical implications of these results as well as areas for future research.

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.     

Teaching Intraverbal Behavior to Children with Autism: A Comparison of Textual and Echoic Prompts

Although echoic prompts may be effective for teaching intraverbal behavior to children with autism, the performance of some children may become dependent on such prompts (i.e., the prompts cannot be eliminated). Recent research suggests that visual rather than echoic prompts may be used to teach children with autism a variety of skills and may facilitate independent performance. In the present study, an adapted alternating treatments design was used to compare the effects of using visual (textual) and echoic prompts on acquisition of intraverbal responses (answering questions) by 2 children with autism. The results indicated that the textual prompts were more effective than the echoic prompts. Implications for the use of visual prompts during instruction with children with autism are discussed.     

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.

The Effects of Multiple-Tact and Receptive-Discrimination Training on the Acquisition of Intraverbal Behavior

The purpose of this study was to determine whether multiple-tact training and receptive-discrimination training could be used to teach thematically related vocal intraverbals to typically developing preschool children. Multiple-tact training involved teaching a child to name both the item and the category to which the item belonged. Receptive-discrimination training consisted of teaching a child to select a picture card in the presence of a question from the experimenter regarding the item or its category. When neither of these strategies resulted in substantial increases in intraverbal responses, a typical intraverbal training protocol using tact prompts was implemented. Six typically developing children participated in the study. A multiple-baseline design across word categories was used to evaluate the effects of the three training procedures. Results indicated that both multiple-tact and receptive-discrimination training had minimal effects on the strength of the intraverbal repertoire, whereas direct intraverbal training had a more substantial effect. The results provide some evidence of the functional independence of verbal operants, as well as the independence of listener and speaker repertoires. Receptive-discrimination and multiple-tact training may have facilitated acquisition of intraverbals; however, further research is needed to assess how these repertoires might interact with each other.     

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.     

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.

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.     

Measles: Current Status and Outbreak Control on Campus

Abstract

This study is part of a nationwide research project dealing with all suicides in Finland. It includes all suicides among university students during the 1-year period from April 1, 1987, to March 31, 1988. Ten students (6 men and 4 women) committed suicide during the period studied. The observed suicide rates per 100,000 students per year were 13.8 (95% CI = 5.1–30.1) for men and 9.0 (95% CI = 2.4–22.8) for women. The difference between the observed and expected suicide rate for men (13.8 v 47.7, standard mortality rate [SMR] = 29) was statistically significant. For women (9.0 v 8.3, SMR = 108), the difference was not statistically significant. Most of the suicides had experienced serious difficulties since early childhood, including narcissistic problems, difficulties in human relations, severe depressive periods, previous suicidal behavior, and alcohol problems; they had also had earlier psychiatric treatment.

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.
