Motor Compatibility Effect on the Comprehension of Complex Manual Action Sentences in L2: An ERP Study

Abstract

Abstract Embodiment theories proposed that the comprehension of language involves sensory-motor simulation in the brain. The present study examined the brain response to motor compatibility effect in comprehending action-related linguistic materials for participants learning Chinese as a second language (L2). In this study, participants are required to read action-related sentences describing an agent performing two manual actions simultaneously or sequentially by manipulating temporal conjunctions. The sentences with simultaneous actions are marked by Chinese parallel structure 一边……一边…… (“while”) showing non-congruent motor condition while the sequential action sentences are marked by 先……然后…… (“after”) showing congruent motor condition. Event-Related Potentials (ERPs) were recorded with the second verb phrase. A larger fronto-central late positivity was observed for the sentences with simultaneous actions rather than the sentences with sequential actions due to body constraints, revealing that late L2 Chinese learners integrate embodied knowledge while processing action-related complex sentence despite demanding more cognitive resources, and longer processing time.
