Grammar and Cognition

This chapter discusses the dualistic characteristics of the Agreement Groups (AG) model of linguistic processing and language acquisition, a usage-based distributional approach building on cognitive mechanisms for storing groups of similar utterances in memory, and mechanisms for mapping utterances onto such groups.
