From Co-Actionality to Extended Intersubjectivity: Drawing on Language Change and Ontogenetic Development

摘要

This article combines research results centred on theory of mind (ToM) from cognitive and developmental psychology (Goldman 2006; Apperly 2010; Wilkinson and Ball 2012) with the notion of intersubjectivity in usage-based linguistics (i.a. Verhagen 2005; Nuyts 2012; Traugott 2012). It identifies some of the controversies in the literature from both domains and suggests the desiderata for a hybrid approach to intersubjectivity, which is distinctively designed to tackle applied research in social and cognitive sciences. This model is based on a mismatch between interaction as mere 'co-action' vs. interaction as spontaneously communicated awareness of an(other) mind(s). It provides a case study centred on the first language acquisition of pre-nominal usage of this/that and such. From, respectively, a distinctive collexeme (Gries and Stefanowitsch 2004) and behavioural profile analysis (Gries 2010) will emerge that beyond expressions of joint attention, children's ToM ability progressively underpins 'ad-hoc' generalized instantiations based on extended intersubjectivity, viz. the socio-cognitive skill to problematize what a general persona would act, feel, or think in a specific context.
