Lexical effect on spoken word recognition of native and non-native speakers of Korean

The present work investigated whether non-native Korean listeners employ two types of lexical information such as word frequency and neighborhood density in their spoken word recognition process. Korean single syllable words recorded by a native speaker of Korean were presented to both native and non-native speakers of Korean in an auditory lexical decision task. Correct response rates and response time (RT) were measured in the task. The experimental result showed native listeners of Korean made use of a competitive effect of neighborhood density and a facilitative effect of word frequency. Non-native listeners were also influenced by word frequency and neighborhood density although they were affected in a different manner when they recognize Korean. In non-native perception of Korean, neighborhood density played a facilitative effect in high frequency words, while it has a competitive effect on the recognition of low frequency words.
