Abstract
This study collected both behavioral and event‐related potential (ERP) data to investigate neural processing of two spatial demonstrative expressions in English, this and that, in social communication. The experimental design employed congruent and incongruent conditions for audiovisual scenarios involving the speaker, the hearer, and the referred‐to object. Behavioral data showed that distance determined the demonstrative form only when the hearer shared the speaker’s gaze at the object. ERP data indicated signficant congruent versus incongruent differences in the poststimulus window of 525–725 ms for the expected demonstrative form, that, when an object was near the hearer and when the interlocutors shared gaze. Global field power (GFP) analysis showed the effect at an earlier window (200–500 ms). There were also significant GFP effects at 100–200 and 300–775 ms associated with specific spatial configurations in relation to the near‐far perceptual distance and shared gaze. Furthermore, standardized low ...
