- Abstract
- This event-related brain potential study investigates whether a visually presented homophone “옻” translates into phonological code /oud/ immediately, and it can activate two meanings “cloth” and “sap of poison oak” or not. To test this hypothesis, this study focused on the difference of N400 component induced by homophone and non-homophone. The N400 is a representative ERP component to reflect semantic activation levels in the brain. The ERP results of 23 subjects who conducted go/no-go lexical decision task show that homophone elicited larger N400 than non-homophone did. Hence, this paper suggests the involvement of phonological code before semantic processes in visual word processing.
