Chambers, C. G., Tanenhaus, M. K. et al. (2002). Circumscribing referential domains during real-time comprehension. Journal of Memory and Language, 47, 30-49.
A head-mounted eye-tracking methodology was used to investigate how linguistic
and nonlinguistic information sources are combined to constrain referential
interpretation. In two experiments, participants responded to instructions to
manipulate physical objects in a visual workspace. Instruction on critical trials
contained definite noun phrases preceded by spatial prepositions (e.g., "Put
the cube inside the can"). Experiment 1 established that the lexical-semantic
constraints of the preposition «inside» immédiately limited
attention to objects compatible with those constraints (i.e., containers), suggesting
that the referential context is dynamically restructured as sentence comprehension
proceeds. Experiment 2 evaluated the additional influence of nonlinguistic constraints
by varying the number of container objects that were large enough to hold the
object being moved. The results indicated that attention was initially restricted
to only those containers large enough to accommodate the object. This outcome
suggests that referential candidates are continuously evaluated in terms of
their relevance for the action denoted by the unfolding utterance. Overall,
the findings are consistent with an expectation-driven interpretive system that
rapidly integrates linguistic information with situation-specific constraints
and knowledge of possible actions.
