Syllable transposition effect on processing the morphologically complex Korean noun Eojeol

The transposition effect was used to describes the early stage of word recognition and to identify whether or not the morphological information is being processed at the early stage (see Lee & Lee 2014, for a comprehensive review). Transposition effect has been carried out mainly through the manipulation of letter units in the Indo-European languages. In contrast, in this study, syllables were used as manipulation units reflecting the characteristics of Korean. Experimental stimuli were manipulated by exchanging the middle two syllables in a four-syllable morphologically complex Korean noun. Within variables were composed of the across morpheme boundary condition (아지버가-아버지가) and the across morpheme boundary condition (자에리서-자리에서). Between variables were composed of the stimulus presentation times which were 50 ms, 100 ms, and 200 ms. The results showed that the transposed conditions were significantly slower than the pseudo nonword condition regardless of the stimulus presentation time. The response time of the within morpheme boundary condition was significantly slower than the across morpheme boundary condition only at the 200 ms condition. These results suggest that the syllable in morphologically complex Korean noun is treated as an independent processing unit, not limited to specific positions. At the same time, results also indicate that the morphological variable tends to modulate the transposition effect of syllable. This means that the processing of morphological variables is in the early stage of morphologically complex Korea noun recognition.
