“…One hundred twenty Korean nouns varying in length and frequency were selected as experimental stimuli. The words contained 1–4 syllables (the number of syllables also representing the number of characters) and the average length was 2.1 syllables ( SD = 0.4) with the majority ( N = 107) being disyllabic, which approximates the length distribution of the Korean lexicon (Yi et al, 2017). Token frequency of the words was measured based on the Sejong corpus of modern Korean written texts of approximately 7.5 million words, comprising of fictional and nonfictional books, textbooks, magazines, and newspaper articles published between 1990 and 2006 (H.-G. Kim et al, 2007).…”

The present study examined age differences in word-frequency effects in Korean visual word recognition through a large-scale, web-based lexical-decision task. Four hundred ninety-seven adult Korean speakers in their 20s through 60s participated in the task, in which they decided the lexicality of 120 Korean words varying in frequency and 120 nonwords. Overall, both lexical-decision accuracy and response times increased with age, and more frequent words were recognized more rapidly than less frequent words. We also found significant effects of participants' reading skill as well as age of acquisition of words. Crucially, despite older adults' generally slower reaction times, there was no hint of any interaction between participant age and word frequency on lexical-decision times. This result adds to the literature on age-related changes in visual word recognition and provides evidence for stable word-frequency effect across the adult age spectrum. These findings are discussed with different hypotheses of lexical access and aging proposed in the literature. Public Significance StatementThis study examined the effect of cognitive aging on the process of visual word recognition, by investigating lexical decisions on Korean words/nonwords by adult speakers from the 20s−60s. We found that although older adults were generally slower than younger adults, the size of the wordfrequency effect on lexical-decision times was constant throughout the age spectrum. These results suggest that the process of word recognition remains relatively constant across the adult lifespan.

Chinese, Japanese, and Korean Writing Systems: All East-Asian but Different Scripts

The three East-Asian scripts—Chinese (characters and Pinyin), Japanese (multi-scripts), and Korean (alphabetic Hangul)—are discussed. Under each script, a brief historical account of the given writing system, the key features of the script, and the strengths and weaknesses as a script are described. The commonalities and differences among the three scripts are next discussed. Since it is claimed that Asian orthography, particularly Chinese characters, curbs Asians’ creativity (Hannas, 1997, 2003), East-Asian students’ performance in international comparison tests is reviewed in comparison to that of American counterparts. Finally discussed are the implications of script differences among the three writing systems for script relativity.
