Constructing a protolanguage: reconstructing prehistoric languages in a usage-based construction grammar framework

Construction grammar is an approach to language that posits that units and structures in language can be exhaustively described as pairings between form and meaning. These pairings are called constructions and can have different degrees of abstraction, i.e. they span the entire range from very concrete ( armadillo, avocado ) to very abstract constructions such as the ditransitive construction ( I gave her a book ). This approach has been applied to a wide variety of different areas of research in linguistics, such as how new constructions emerge and change historically. It has also been applied to investigate the evolutionary emergence of modern fully fledged language, i.e. the question of how systems of constructions can arise out of prelinguistic communication. In this paper, we review the contribution of usage-based construction grammar approaches to language change and language evolution to the questions of (i) the structure and nature of prehistoric languages and (ii) how constructions in prehistoric languages emerged out of non-linguistic or protolinguistic communication. In particular, we discuss the possibilities of using constructions as the main unit of analysis both in reconstructing predecessors of existing languages (protolanguages) and in formulating theories of how a potential predecessor of human language in general (protolanguage) must have looked like. This article is part of the theme issue ‘Reconstructing prehistoric languages’.

Language Development in Down Syndrome

This chapter is a review of research on language development in individuals with Down syndrome. The development of various aspects of language is described from infancy to adulthood, with a focus on gestures and prelinguistic communication, speech, vocabulary, syntax, and pragmatics. In each area, the profile of relative strengths and weaknesses is described, as well as the trajectory of development, and differences relative to other disorders, and the influence of other aspects of the phenotype of individuals with Down syndrome (e.g., memory impairments). Research is briefly reviewed on possible influences of the social and linguistic environments of individuals with Down syndrome on their language development. The chapter focuses on research on the learning of English as a first language; however, where possible, data from other languages and cultures is considered. Directions for future research are outlined.

Modelling the early expressive communicative trajectories of infants/toddlers with early cochlear implants

For children with normal hearing (NH), early communication skills predict vocabulary, a precursor to grammar. Growth in early communication skills of infants with cochlear implants (CIs) was investigated using the Early Communication Indicator (ECI), a play-based observation measure. Multilevel linear growth modelling on data from six ECI sessions held at three-monthly intervals revealed significant growth overall, with a non-significant slower growth rate than that of children with NH (comparison age centred at 18 months). Analyses of gesture use and of nonword vocalisations revealed the CI group used significantly more of each, with more rapid growth. In contrast, the CI group used significantly fewer single words and multiword utterances, and with slower growth. Maternal education and time to achieve consistent CI use impacted significantly on growth for the CI sample. The results indicate that progression to vocabulary by young CI users can be supported by encouraging their use of prelinguistic communication.
