Recognition of Second Language Spoken Words, Signs, and Characters Via Perception and Production in Adults

Plain-language summary

Self-production facilitates acquisition of spoken words, signs, and characters from an unfamiliar second language. The proposed work investigates how motor cortex, a key part of the brain enabling body action, supports their acquisition via production as well as perception, providing insight into whether they are learned via mental simulation of the body actions used to produce them. It is hypothesized that activity in motor cortex will differ based on the body part used to produce lexical items (e.g., mouth vs. hands), will be greater for lexical items learned via production than observation, and will differentiate lexical items recognized successfully vs. unsuccessfully.
