Abstract:
Embodied views of language support that facial sensorimotor information can modulate language comprehension. The aim of this study is to test whether the syntactic processing of simple sentences, as measured with event-related brain potentials (ERP), could be affected by reader's facial expressions. Participants performed a correctness decision task using sentences that could be either correct (50%) or contain a morphosyntactic disagreement (either in gender or number), while making one of four facial expressions: participants either (a) posed no facial expression (“control” condition) (b) brought their eyebrows together, making the ends of two golf tees touch (“frown” condition), (c) held a pencil with their teeth (“smile” condition), or (d) held the pencil using their lips (“non-smile” condition). In all conditions the customary left anterior negativities did not appear. In contrast, an N400-like component emerged, which was larger for the “frown” condition and reduced in the “smile” and “non-smile” conditions. These results can be interpreted as the consequence of either an unconscious emotion induction or an interplay between the motor and the language systems subsequent to the effort needed to hold the facial expression. ; 8
