The present study evaluated the validity and efficacy of the Promoting the Emergence of Advanced Knowledge Relational Training System Equivalence Module (PEAK-E) using a single-case, multiple baseline across skills design with 3 adolescents with autism. Total scores from the PEAK-E assessment (PEAK-E-A) and programs were used to evaluate the degree to which the assessment was able to identify language skills to teach using the PEAK-E curriculum, and how effective the PEAK-E curriculum was at teaching those target skills. Baseline results suggested that the programs selected using the PEAK-E-A were not currently in the participant’s language repertoire. Upon completion of 9 total programs across three participants (3 programs per participant), mastery was achieved and all derived relations emerged for all 9 programs. The PEAK-E pre-assessment, assessment, and training programs were proven to be valid and efficacious at improving participant’s language skill repertoire.

This study hypothesized a direct relationship among three verbal phenomena: derived relational responding, verbal intelligence, and worry. It also hypothesized that experiential avoidance would mediate the relationship between derived relational responding and worry. Overall, results from this study failed to support a relationship between worry and the other two verbal phenomena, however, results did support a relationship between derived relational responding and verbal intelligence. Additionally, results indicated a significant relationship between experiential avoidance and worry. Future research should clarify the relationship among the three primary variables of interest, improve measurement of these variables, be more sensitive to external validity, and promote the study of acceptance-based treatments that target experiential avoidance.

Approximately 1.7 million people sustain a traumatic brain injury each year in the United States. Perspective taking is a repertoire known to be severely affected following a traumatic brain injury. The ability to take the perspective of another greatly contributes to social interactions and involves a complex set of skills. A small number of studies have attempted to train perspective taking skills in populations lacking the ability, but none with individuals diagnosed with TBI. This study aimed to teach perspective taking skills to adults with TBI through established protocols which teach deictic relational frames. Three adult males with traumatic brain injuries were exposed to the deictic relational training protocol. Each participant was tested on traditional theory of mind tasks prior to and following mastery of deictic training. All three participants achieved mastery of the relational training protocol and showed some improvement on theory of mind tasks following training and at follow-up.

Children's language and world knowledge grows explosively in the preschool years. One critical contributor to this growth is their developing ability to infer relations beyond those that have been directly taught or modeled. Categorization is one type of skill commonly taught in preschool in which inference is an important aspect. This study explored the development of specific types of inferences within a categorization relation: those among naming items and categories, selecting items based on their names and categories, and answering questions that relate names and categories. Children learned names and categories for a set of unfamiliar cartoon characters through one of two training protocols: (a) Listener training involved selecting a picture upon hearing an item name or category; (b) Expressive training involved saying an item name or category upon seeing a picture. Following training, we tested whether children derived several kinds of untrained responses. Those children who received Expressive training (saying names) completed tests of listener responses (selecting pictures); similarly, those children who received Listener training (selecting pictures) completed tests of expressive responses (saying names). Next, children answered oral questions in the absence of pictures. Results show that children receiving Expressive and Listener training produce naming and question answering responses at levels above chance. However, many children failed to answer all questions correctly. The Expressive group produced naming and question answering responses at significantly higher levels than the Listener group. This suggests that Listener training is a weaker form of instruction when the goal of instruction is the production of untrained responses. However, these results are tentative because unequal proportions of children completed each type of training. Finally, we examined the relationship between naming and question answering. Few children answered questions at a higher level than they produced names. This study shows that children learn to infer responses from both Listener and Expressive trainings. This study also suggests that naming and question answering responses are related responses. The current study highlights the need for later research on teaching inference skills such as naming and question answering to those who do not develop them in the absence of specific instruction.

Os trabalhos iniciados por Sidman em 1971 alargaram os horizontes da Análise Experimental do Comportamento neste campo de estudos, sobretudo ao que se refere à linguagem e/ou comportamento simbólico. As extensões, ramificações e derivações dos trabalhos de Sidman têm gerado desde então incontáveis trabalhos empíricos e teóricos. A natureza do operante discriminado tomou vertentes e vultos bastante diferentes e complexos, por conseguinte, extensas discussões sugiram. O presente trabalho tenta contribuir com estas discussões e teve como objetivo propor um procedimento de treino discriminativo alternativo às propostas atuais sobre responder relacional e emergência de relações entre estímulos, baseado em discriminações simples simultâneas e utilizando-se estímulos compostos. Os resultados obtidos mostram ser o procedimento viável para o estudo do responder relacional e emergência de relações entre estímulos. Sugerem ainda uma reflexão sobre as características definidoras do responder relacional e emergência de relações entre estímulos. Indicam também que o repertório comportamental pré-experimento dos participantes é uma variável bastante relevante e que deve ser considerada e estudada como mais atenção.

Relational Frame Theory research involves either of two protocols utilized to establish relational networks and functions for stimuli in those relational networks. Years of research indicate the most prevalent method involves first establishing a relational frame, conditioning one of the stimuli to acquire a particular function, and then providing a test to see if the function trained to one of the stimuli in the network transferred through the relational network to other stimuli. The less common method involves first training a particular function for a stimulus, entering that stimulus in a relational network with at least two other stimuli, and then subsequently providing a test to see if the function transferred. Hayes, Kohlenberg, and Hayes (1991) hypothesized that not only do both procedures work, but there is also no differentiation between the two with regards to transformation of stimulus function. Although both protocols have been used in the RFT literature, a direct comparison has never been made. The current study directly examines that comparison in a within-subject analysis to determine if there may be differentiated results in transformation of stimulus function based on the protocol used. A within-subjects analysis indicates that subsequent probes of transformation of stimulus function probes yielded similar levels of correct responding in both training protocols, and thus supporting the hypothesis put forth by Hayes and colleagues (1991).

Perspective taking is a pivotal behavioral repertoire essential for social functioning and is recognized as a hallmark deficit of the Autism Spectrum Disorder. Recent advancements in the Relational Frame Theory have led to the development of a perspective-taking training protocol shown to improve performance on Theory of Mind tasks in typically developing children; however, there has been little research on the generality of these findings in children with ASD. The impact of deictic responding on social interaction is also undetermined. The current study aimed to: a), evaluate the effectiveness of multiple exemplar training of deictic relations on perspective taking abilities in children with ASD, b), assess the impact of deictic relations on naturalistic Theory of Mind tasks, and c), assess generality of the deictic repertoire on pretend play. All three participants acquired deictic repertoires through double reversed complexity. Acquisition of the relational operants was variable and required many sessions for each participant. Two of three participants showed transfer of perspective taking to the Strange Stories test, all three participants showed overall improvement in performance on various Theory of Mind tasks; and lastly, participants showed mixed results on transfer to pretend play. Implications for using multiple exemplar training in supporting social understanding, prerequisite skills for deictic relational responding, and training strategies are discussed.

The purpose of this study was to replicate and extend recent findings in the functional contextual literature by 1) establishing complex deictic relational responding skills in 3 persons diagnosed with Schizophrenia and mild-moderate Mental Retardation and 2) assessing generalization through pre and post-instructional measures of Social Anhedonia and Theory of Mind functioning. Results suggest that increasingly complex levels of deictic relational responses were acquired and mastered by all 3 participants and that generalization extended to the Deceptive Container Task (ToM levels 4 & 5) and Hinting Task. Support is provided for the notion that perspective taking skills might be shaped through operant conditioning of deictic frames and that acquisition of these skills may generalize to novel stimuli and settings.
