CARTA: How Language Evolves: Ann Senghas: Rethinking Recapitulation: Sources of Structure in Nicaraguan Sign Language

4/3/2015; 19 minutes

In this talk Ann Senghas traces the development of basic sentence structure and vocabulary in Nicaraguan Sign Language, in order to uncover the effect of language acquisition processes on language emergence and convergence across age cohorts. Evolutionary principles must apply not only to the development of humans as language learners, but also to the development of languages as systems that change and adapt over generations. Recorded on 2/20/2015. (#29399)
