It is by now well-known that in speech communication, the same string of words can be uttered differently as a function of different preceding discourse contexts. Little, however, is known about how exactly discourse context affects the way an utterance is formulated (or planned). In this talk, I will discuss results of two studies which aimed to shed some light on this issue. In both studies, participants described pictures of two-character transitive events and their eye fixation patterns were recorded (via an eyetracker), together with the response time of their speech, as indices of their utterance planning processes. The first study zoomed into the effect of focus while the second one giveness, two important dimensions of discourse context on sentence planning. Results suggest that discourse context affects the time course of linguistic formulation in simple sentences but its effect can be modulated by language-specific linguistic structures as well as the planning scope of the utterance (which provides further evidence for highly incremental planning in sentence production).
