Abstract
The writing systems have been developed by regard that how sound is written to express phonology in letters. So to interpret the written words, the phonological orthography is deemed to have serious contribution. In researches, the decoding processes of phonology have been concerned, proposing some theories as orthographic depth hypothesis, and phonological primary principle. However the other aspect of orthography has been raised with regard of how to reserve morphology in writing. Also to understand the written words, the analysis of the morphological orthography is viewed to help readers. So in researches, some of morphological effects have been analyzed. This study presupposed two-dimensional category of phonology and morphology to set various writing systems. Attempting to confirm the two dimensions, an experiment was designed to analyze both of phonological and morphological effect. For the purposes, the intrusion effect of phonology or morphology was proposed as what is sensitive to working of the two dimensions. This study observed the intrusion of phonology which influenced on the semantic task which required judging whether same or different in meaning between prime and target. And also the intrusion of morphology was observed when judging sounds between prime and target was required. This study sampled Korean and Chinese words both of which belong to Korean language, and each of which is posited by this study to be distributed differently in the two dimensions of phonology and morphology. The analysis of the results showed both of the sound and meaning intrusion, concluding that Korean writing system kept the two-dimensional category of phonology and morphology. Therefore this study pointed out the limit of one-dimensional category hitherto accepted, where each of the phonological and morphological orthography is posed at each of the two extremes in one-dimension, requiring the further tests on the other languages to make generalization of the two-dimensional category of phonology and morphology proposed and supported by this study.
Highlights
What are defined as the writing system are various over worldwide
It is concluded that the writing systems are categorized by not one-dimensional but two-dimensional category of phonology and morphology
What was most figural is that the intrusion effects both of phonology and morphology were observed within a writing system of Korean and designed as within subject variables
Summary
What are defined as the writing system are various over worldwide. To categorize them, varieties of criteria have been attempted. The strong phonological effect was shown in the shallow depth of the writing systems as Spanish, and Serbo-Croatian, and the reverse was found in the deep orthography as Hebrew and English (Frost, Katz, & Bentin, 1987). The two are independent to set up properties of writing system Applying this position to the above orthographic depth hypothesis, what is limited is found in the premise as the morphological properties are dependent on the phonological ones, in other words as phonological depth is to correlate a level of morphological dimension. Discussing dimensions where to place Korean and Chinese, in one dimension, Chinese and Korean are mentioned to be different only in levels of phonological transparency; Chinese is placed to opaqueness, but Korean
