Recent years saw a growing interest in the study of subjectivity, as the linguistic expression of speaker involvement. Intersubjectivity, defined by Traugott as "the linguistic expression of a speaker/writer's attention to the hearer/reader", on the other hand, has so far received little explicit attention in its own right, let alone systematic definition and operationalization. Intersubjectivity and seemingly related notions such as interpersonal meaning, appraisal, stance and metadiscourse, frequently appear in cognitive-functional accounts, as well as historical and more applied approaches.
The Shared Mind: Perspectives on intersubjectivity
The Shared Mind challenges the conventional "theory of mind" approach, proposing that the human mind is fundamentally based on intersubjectivity: the sharing of affective, conative, intentional and cognitive states and processes between a plurality of subjects. The socially shared, intersubjective foundation of the human mind is manifest in the structure of early interaction and communication, imitation, gestural communication and the normative and argumentative nature of language.
Constructions of Intersubjectivity shows that the meaning of grammatical constructions often has more to do with the human cognitive capacity for taking other peoples' points of view than with describing the world.
