The Locus of Word Length and Frequency Effect in Comprehending English Words by Korean-English Bilinguals and Americans
Three experiments on English word recognition have been conducted in order to investigate the locus of word length effect, as well as the locus of the frequency effect. The other aim of this study was to investigate whether the processing of English word recognition for Koreans is similar to that of Americans’ or not in the respect of word length and frequency effects. In all experiments, the interacting pattern between length and frequency was examined. If the interaction is additive, length and frequency affect separate stages. Experiment 1 showed that degradation of stimuli by mixing the case had no effect on word length and frequency. The processing patterns between the naming and the lexical decision (Experiment 2), and between the naming and the delayed naming (Experiment 3) were similar for both word length and frequency effects. In addition, Korean bilinguals showed similar length and frequency effect as American. The locus of length effect is located at the lexical access and a post-lexical stage. Because word frequency and length are two most influential lexical variables in word recognition, this result indicates that Korean bilingual access the lexical system of English as much the similar way as American.
