Dr.McGrath's belief that both innate predisposition and a supportive environment contribute to language development is most consistent with the interactionist theory, which posits that language acquisition is influenced by both innate biological factors and environmental input, particularly social interaction with caregivers and other speakers. The behavioral theory emphasizes the role of environmental conditioning, while the nativist theory emphasizes innate, genetically determined factors. The Whorfian theory focuses on how language shapes thought and perception.
