Interkinesics and interprosodics in second language acquisition Gassin, June,, 15, 95-106 (1992), doi = https://doi.org/10.1075/aral.15.1.06gas, publicationName = John Benjamins, issn = 0155-0640, abstract= This paper assumes the unified nature of language behaviour including verbal, kinesic and prosodic forms. In the light of this, it proposes that Interlanguage Theory should be expanded to include kinesic and prosodic modes of behaviour. It presents the hypothesis that the acquisition of second language kinesic and prosodic forms takes place in a similar fashion to acquisition of second language verbal forms acquisition is developmental; it is subject to mother tongue interference; it can undergo fossilization. It is further hypothesised that fossilization in kinesic and prosodic forms may have cognitive and emotional implications and may even impede the second language learner in his/her development on the verbal level., language=, type=
