This volume emphasizes the emergence of linguistic development through children's and learners' interactions with their environment - spatial, social, cultural, educational - bringing to light commonalities between primary language development, child and adult second-language learning, and language acquisition by robots. The studies presented here challenge a number of dominant ideas in language acquisition theory. It is of interest to language acquisition researchers and professionals.
