Abstract

Nonword trials are a necessary part of the lexical decision task and their composition can affect the responses to experimental words in the task. To investigate the role of nonwords in visual recognition of Korean words, the nonword type and its proportion in a list were manipulated. The results showed that the frequency effects of bisyllabic Sino-Korean (SK) words were smaller when they appeared among nonwords made of SK syllables than among nonwords with non-SK syllables or non-used syllables. The effect of nonword type was also stronger for low-frequency words. In addition, the proportion of nonwords included in a list influenced lexical decisions to words. The smaller the proportion of nonwords in a list, the faster decisions were made to words. The proportion of nonwords did not interact with word frequency. The present results call for more attention to nonwords in Hangul word recognition.
