Investigations in universal grammar

This introductory guide to language acquisition research is presented within the framework of Universal Grammar, a theory of the human faculty for language. The authors focus on two experimental techniques for assessing children's linguistic competence; the Elicited Production task, a production task, and the Truth Value Judgment task, a comprehension task. Their methodologies are designed to overcome the numerous obstacles to empirical investigation of children's language competence. They produce research results that are more reproducible and less likely to be dismissed as an artifact of improper experimental procedure.
