Abstract

Growing boy of studies focus on the letter transposition effect since it gives the information on how letters are coded and what variables are involved in the processes of word recognition. This review investigated various models on letter transposition effect. While most proposed models rely mainly on the bottom-up processes, evidences from various studies suggested the necessity of the top-down variables based on the cognitive processing mechanism. Especially, empirical evidences suggested that Hangul model should include a position specific processing mechanism based on onset, vowel, and coda of the Korean character.

단어내의 글자들을 교환하여 제시할 경우 원래의 단어로 혼동하는 현상인 글자 교환 효과에 대한 연구가 활발하다. 이는 글자교환 효과에 대한 연구가 시각단어 재인시 글자가 어떻게 부호화 되는지와 단어재인 초기과정에 영향을 주는 변인과 처리과정에 대한 정보를 제공하기 때문이다. 본 소고에서는 글자교환 효과에 대한 기존의 설명 모형들을 살펴보고, 하향적 인지적 처리를 반영하는 모형의 필요성을 논의하였다. 특히 한글 처리의 경우, 글자의 위치가 정해져 있지 않고 유동적이라고 보는 기존의 모델들과 달리 하향식으로 글자의 위치가 어휘 하위 단위인 초성, 중성, 종성으로 지정되어 있다는 가정이 필요하다. 따라서 이에 기반한 모형을 탐색하고 추후 연구방향을 논의하였다.
