The importance of language for language development: Linguistic determinism in the 1980s

Abstract

The semantic and syntactic functions of verbs are the major aspects of linguistic complexity that contribute to the cognitive requirements for learning language between two and three years of age. Several contrastive categories of verbs emerged from our studies with action/state as the largest and most general. Contrastive subcategories of action verbs were locative/nonlocative action, durative/nondurative action, and completive/noncompletive action. The subcategories of state verbs were volitional/epistemic/notice/communication states. The psychological and linguistic validity of these semantic categories rests on their being coextensive with major grammatical developments and/or their sequential development
