This module investigates factors that influence bilingual language development. Evaluators who work with bilingual children must be familiar with typical second language acquisition, including phenomena such as subtractive bilingualism, the silent period, and code-switching. The effects of sociocultural background, personality and individual differences on bilingual language acquisition are discussed. In addition, Cate presents research that has demonstrated how similar second language acquisition can seem when compared to specific language impairment in monolingual speakers. This is why evaluators need the appropriate knowledge base to make an accurate diagnosis.
