Verbal behavior development theory and relational frame theory: Reflecting on similarities and differences

Area of Science:

• Behavioral science
• Cognitive psychology
• Developmental psychology

Background:

• Relational frame theory (RFT) and verbal behavior development theory (VBDT) are behavior-analytic frameworks for language and cognition.
• Though both rely on Skinner's analysis of verbal behavior, they have developed independently, with RFT in clinical psychology and VBDT in education.

Purpose of the Study:

• To overview RFT and VBDT.
• To explore intersections between RFT and VBDT based on recent conceptual advancements.
• To integrate insights for understanding early language development and incidental learning.

Main Methods:

• Conceptual analysis of RFT and VBDT.
• Identification of shared principles and points of contact.
• Exploration of how behavioral developmental cusps facilitate incidental language learning.
• Examination of arbitrarily applicable relational responding and mutually entailed orienting in RFT.

Main Results:

• VBDT highlights how developmental cusps enable incidental language learning in children.
• RFT advancements detail dynamic variables in arbitrarily applicable relational responding.
• Mutually entailed orienting is proposed as a cooperative act driving relational responding.
• Both theories offer functional analyses applicable to early language and name learning.

Conclusions:

• RFT and VBDT provide complementary perspectives on early language development.
• Integrating these theories enhances understanding of children's incidental learning of names.
• Further research can explore the functional analyses generated by both approaches.
