Lexical Decision and Semantic Relatedness Judgment Processing

Numerous studies on semantic memory observed that neurologically healthy monolinguals are faster and more accurate in processing concrete than abstract words. This study examines concreteness effects in lexical decision and semantic relationship judgment tasks in the second language in bilinguals and in the first language in people with aphasia, and the relationship between concreteness and types of semantic relationships. Implications for bilingual semantic memory and comparisons between L2 and impaired L1 will be discussed.
