Can stroke count influence the visual span in Korean Hangul reading? Youngon Choi SeongWoo Jeong Tae Hoon Kim Psychology, Chung-Ang University Psychology, Kyungnam University The aim of the present study was to examine the effect of pattern complexity, in particular, the number of strokes involved in forming a syllable-based character, on the visual span in Korean Hangul reading. The visual span refers to the number of characters that can be accurately recognized without moving one s eyes in reading and has been related to individual differences in reading speed. The concept of the visual span, however, has only been applied to English and Chinese scripts thus far. Korean Hangul writing system is quite unique, having alphabets combined into a syllable and each syllable written in a restricted space. This differs from both English alphabetic serial writing and Chinese logographic writing system. Due to its unique combinatorial nature of the script, the pattern complexity of Hangul can be affected by stroke frequency as well as by the type of alphabet combination (e.g., CV vs CVCC). Using a trigram presentation method, we found that participants who viewed characters with 2-7 stroke frequency had higher accuracy than those who viewed characters with 8-15 strokes only in their right visual field. No main overall difference or the difference in the left visual field was observed, suggesting that stroke frequency may not be a critical sensory limiting factor on the visual span for Hangul reading. Key words : visual span, stroke count, Korean Hangul, reading abilities
