We study how children learn language and also how language learning can break down. We take the perspective of language learning as part of a larger cognitive-linguistic learning profile. Thus, we examine how language learning and nonlinguistic cognitive processing are linked within fundamental learning mechanism and whether and how limitations in this mechanism potentially affect language difficulties in children. We invite both bilingual and monolingual children with and without language difficulties to help us answer our research questions. Our aim is to broaden our perspective on cognitive-linguistic theories of language learning and to achieve more accurate assessment and more effective intervention services for children who have language difficulties.
