시각 단어 재인시 나타나는 음절 빈도효과의 원인 규명 : 사건관련 뇌전위 연구
The Source of the Syllable Frequency Effect During Visual Word Recognition : Event-Related Brain Potential Stud
The purpose of the current study is to investigate whether the syllable type frequency or the syllable token frequency is responsible for the syllable frequency effect during visual word recognition. In the present ERP study, type and token frequencies of the experimental materials were orthogonally controlled and 20 participates were performed a lexical decision task. The results showed that the P200 and N400, which have been known as ERP components to mirror syllable processing, were affected by the modulation of the syllable token frequency rather than by the modulation of the syllable type frequency. The results of the current study suggested that the syllable type frequency is the major source of the syllable frequency effect during visual word recognition.
