Verbal Behavior

Instructional Demonstrations are More Efficient Than Consequences Alone for Children with Naming Abstract Prior research found that without the naming cusp, children did not learn from instructional demonstrations presented before learn units (IDLUs) (i.e., modeling an expected response twice for a learner prior to delivering an instructional antecedent), however, following the establishment of naming, they could. The present study was designed to compare the rate of learning reading and mathematics objectives in children who showed naming using IDLUs compared to standard learn units (SLUs) alone (comparable to three-term contingency trials). In Phase 1, a pre-screening phase, we demonstrated that four typically developing males, 3 to 4 years of age, had naming within their repertoire, meaning they were able to master the names of novel 2-D stimuli as both a listener and a speaker without explicit instruction. Using the same participants in Phase 2, we compared rates of learning under two instructional methods using a series of repeated AB designs where conditions (IDLUs versus SLUs) were counterbalanced across dyads and replicated across participants. The participants learned more than twice as fast under IDLU conditions and showed between 30% and 50% accuracy on the first presentation of a stimulus following a model. The IDLU condition was more efficient (fewer trials to criterion) than the SLU condition. These findings, together with prior findings, suggest that the onset of naming allows children to learn faster when instructional demonstrations are incorporated into lessons.

Empirical Evaluations of Skinner's Analysis of Problem Solving Abstract We reviewed 12 studies in which the researcher taught problem-solving strategies, such as self-questioning and visual imagining, to children and adolescents with and without disabilities to facilitate the learning of math, spelling, play/social, and communication skills. We analyzed these studies in terms of types of problem-solving strategies, the multiple control involved in problem solving, the extent to which problem solving occurred at the overt or covert level. In addition to suggesting limitations of the literature, we recommend areas for future research and practice.

An Evaluation of Conditional Manding Using a Four-Component Multiple Schedule Abstract Most verbal behavior curricula for children with autism spectrum disorder (ASD) focus on teaching multiple mands during the early stages of training (e.g., picture exchange communication system; Bondy & Frost, 1994). However, few, if any, of those curricula train children with ASD to differentially mand only for reinforcers that are reasonable for a caregiver to deliver in a given context (e.g., mands to cuddle at bedtime) and to refrain from manding for reinforcers that would be inappropriate to deliver in that context (e.g., mands to play outside at bedtime). In this study, we first taught a boy with ASD two initial mands. Immediately thereafter we brought those mands under the conditional discriminative control of a four-component multiple schedule with (a) S1 correlated with one reinforcer available (i.e., edibles), (b) S2 correlated with both reinforcers available (i.e., edibles or drink), (c) S3 correlated with another reinforcer available (i.e., drink), and (d) SΔ correlated with no reinforcer available. Following treatment, the child displayed conditionally discriminated manding in accordance with each of the four components of the schedule. We discuss these findings relative to the potential benefits of bringing mands under both evocative and discriminative control.

Further Evaluation of the Stimulus Pairing Observation Procedure with Children with Autism Spectrum Disorder Abstract A large amount of learning occurs through the observation of stimulus-stimulus relations. One procedure that involves this sort of learning is the stimulus-pairing observation procedure (SPOP). The current study involves a systematic replication of Byrne, Rehfeldt, and Aguirre (2014). Tests for the emergence of tact and listener relations were conducted pre- and post-SPOP intervention, which consisted of a therapist presenting auditory-visual stimulus relations to participants. The SPOP intervention resulted in the establishment of tact and listener relations for all participants. The importance of assessing prerequisite skills is considered in the context of previous research.

Further evidence of automatic reinforcement effects on verbal form Abstract The form of a verbal response allows for reinforcement mediation and language transmission across cultures. Reinforcement, in turn, plays a decisive role in learning verbal forms. The present work addresses methodological limitations of previous studies, providing further evidence of the role of automatic reinforcement in achieving parity with vocal models. In the first experiment, 4 preschool-age children heard the experimenter describe drawings of different actions in the passive voice. Participants were then asked to describe analogous drawings. They used the passive voice after the model was presented and continued to do so even when preferred explicit consequences followed diverging descriptions (i.e., in the active voice). To further investigate the effects of explicit reinforcement and of the passive-voice model, in Experiment 2, we altered the number of trials with explicit reinforcement and with the model. Three of four participants used the passive voice to describe the drawings, despite greater exposure to explicit consequences following descriptions diverging from the model.

Enhancing Instruction via Instructive Feedback for a Child With Autism Using a Speech-Generating Device Abstract Instructive feedback (IF) is a procedure in which secondary targets are presented to a learner during instruction for primary skills. Previous research has demonstrated that students with autism spectrum disorder (ASD) may acquire at least a portion of skills presented via IF. Although it is a promising instructional methodology for learners with ASD, few studies focus on learners who use an augmentative device for communication purposes. The purpose of the current investigation was to extend the IF literature related to students with ASD who use communication devices. Across all target skills, IF resulted in the acquisition of at least a portion of secondary targets without explicit teaching.

An investigation of the effects of a parent delivered stimulus-stimulus pairing intervention on vocalizations of two children with Autism Spectrum Disorder Abstract Communication deficits in children with Autism Spectrum Disorder (ASD) can manifest in a myriad of lifelong social and educational challenges. Many children with ASD fail to learn vocal verbal behavior and may require intensive individualized intervention to learn early verbal operants. The current research aimed to evaluate the effects of a parent delivered stimulus-stimulus pairing (SSP) procedure on target vocalizations of two young children with ASD who did not present with vocal verbal behavior. Results indicated the intervention was successful in increasing the frequency of the target vocalizations for both participants. Social validity results indicated that parents were satisfied with the intervention and their own implementation of these procedures. These results are discussed in terms of their implications for parent delivered interventions.

Evaluating the Effects of Similar and Distinct Discriminative Stimuli During Auditory Conditional Discrimination Training With Children With Autism Abstract Children with autism are often taught auditory conditional discriminations in the form of personal information questions that might prove useful in conversation (e.g., "What is your favorite food?" "Pizza" and "What is your favorite color?" "Purple"). In these questions, the auditory stimuli presented as part of the compound discriminative stimulus (i.e., what, favorite, color/food) do not always simultaneously control responding. If all components of the auditory stimulus do not control responding, a child may master 1 target but have trouble acquiring subsequent targets that have a component of a previously learned auditory stimulus because the previously learned response is emitted. One way to avoid this problem is to teach many targets that have no overlapping component stimuli before introducing targets that include a previously learned component. Another way to avoid the problem is to systematically introduce overlapping stimulus components simultaneously to facilitate control by all relevant components. Three children with autism were taught auditory conditional discriminations. An adapted alternating-treatments design was used to compare the use of training sets with programmed overlap of component auditory stimuli to training sets with no overlap of stimulus components. The effects of these 2 arrangements were evaluated on trials to criterion and percentage accuracy during acquisition. All participants reached mastery faster with at least 1 target set in the nonoverlap condition compared to the overlapping condition; 2 out of the 3 participants met the mastery criteria for both overlapping and nonoverlapping targets at a similar rate by the 3rd training set.

The Future of Verbal Behavior: Integration Abstract The future of verbal behavior research is integration. Different perspectives and research areas with their respective sets of jargon exist, which could lead one to believe in competing perspectives. However, a close inspection of various areas suggests overlap between those areas. Integrating research from across differing perspectives could result in a comprehensive understanding of verbal behavior.
