Association for Behavior Analysis International

Verbal Development Theory (VBT) has focused on which cusps and capabilities are related to and/or necessary for the devlopment of advanced verbal repertoires. Also of interest are the relations between and among different types of complex verbal relations. This current body of research extends the findings supporting VBT. In the first paper, the author investigated the relations between gradients of bi-directional naming (BiN) and the emergence of arbitrarily applicable relations in young children. The author of the second paper investigated the aquisition of BiN in both monoloingual children and children who were English language learners. In the third paper, the author investigated whether an intensive tact procedure was effective in increasing joint attention responses in preschoolers who previously did not demonstrate the initiation of joint attention. The results of this research expand on what we know about the acquisition of complex verbal behavior.

Behavior Anlayst Supervisors, advanced practioners

There is growing interest in children’s acquisition of complex language repertoires across domains of behavior analysis. In three experiments, I studied the sources of reinforcement for bidirectional naming (BiN) and the implications of the naming continuum on the emergence of arbitrarily-applicable relations (AAR). In Experiment 1, I tested the correlation between repeated pairings of auditory and visual stimuli (defined by the presentation of naming experiences using a storybook) and emergence of BiN. Listener responses significantly increased across three repeated experiences, suggesting the emergence of unidirectional naming (UniN); however, speaker data remained low. In Experiment 2, I tested the role of echoics on the emergence of BiN. The data suggested that echoic responding was not significantly related to BiN. I then tested the effects of the proximity of visual and auditory stimuli on the emergence of BiN using repeated stimulus pairings (tact experience). While the degree of BiN was not reliably affected by proximity conditions, results of the study showed the emergence of untrained language relations. I discuss these findings with regards to the relation between the joining of listener and speaker responses, the establishment of BiN, and the emergence of AAR.

In this study, I assessed the bidirectional naming (BiN) capabilities of 16 English Language Learners (ELL) and monolingual English preschool-aged students. Participants were divided into 2 group and assessed for the presence of BiN, in English and Spanish, using novel familiar stimuli. Group I consisted of ELL students while Group II was made up of native English-speaking students. Preliminary results showed that all only 1 participant demonstrated the presence of BiN across both languages, while all others, regardless of their native language, demonstrated higher degrees of unidirectional naming (UNi) or BiN in English. Subsequently, these students were matched based on levels UNi and underwent a repeated probe procedure using a simultaneous treatment design. The experimenters used novel sets of familiar stimuli during each intervention session to test the effects of this procedure and to compare the degree of BiN across ELL and monolingual English students. Results showed increases in untaught listener and speaker responses for monolingual English students and variable levels of responding for English Language Learners.
