Phonological Preparation in Korean: Phoneme, or Syllable or Another Unit?

Abstract

With three experiments, the present study investigated the primary phonological preparation (PP) unit in spoken word production in Korean. Adopting the form preparation paradigm, 23 native Korean speakers named pictures in homogenous or heterogenous lists. In homogenous lists, the names of the pictures shared the same initial phoneme (Experiment 1), initial consonant + vowel (i.e., CV) body (Experiment 2), or initial consonant + vowel + consonant (CVC) syllable (Experiment 3); and in heterogenous lists, the names did not share any phonological components systematically. Compared to naming pictures in heterogenous lists, participants’ naming speed was significantly faster when the initial body or the initial syllable of target names was shared. However, this form preparation effect was not shown in Experiment 1, when only the initial phoneme was shared. These results suggested that the body serves as the primary PP unit in Korean, that is, native Korean speakers tend to plan spoken words in a body–coda fashion, probably due to a joint contribution from the strong prevalence of the CV structure and early literacy instructional approach.
