| summary | Until recently, there has been little evidence regarding how and when infants begin to integrate words into an inter-connected lexical-semantic system. Recent event-related potential (ERP) studies show that lexical-semantic system emerges together with early vocabulary during the second year of life (Rämä et al., 2013; Rämä et al., 2018). These studies also suggest that the N400 component is an useful tool to investigate lexical-semantic development in infancy. Some further evidence shows that lexical-semantic organization develops later in bilingual than in monolingual infants. There is mixed evidence as to whether lexical-semantic activation occurs similarly in dominant and non-dominant languages in bilingual language learners (e.g., Sirri & Rämä, 2019). In my talk, I will present our findings regarding neurophysiological mechanisms underlying lexical-semantic activation in monolingual and bilingual infants, and I will also describe my recent findings on the effect of speaker familiarity on processing of word meanings. |
