Abstract

Sex differences in word perception are an important issue in reading. Previous studies that used various word perception tasks have indicated that girls outperform boys. The composite paradigm is a typical task for measuring visual perception and was employed here to identify the age at which sex differences in the perceptual processing of Chinese characters emerge. We tested 124 typically developed children from junior (6–7 years) and middle grades (9–11 years), studying in a primary school. Chinese character processing was better in congruent than incongruent conditions for all children with one or more years of experience in learning Chinese characters. Importantly, girls in the middle grade showed better discrimination sensitivity performances than boys, whereas no sex differences were found in the junior grade. These results suggest that sex differences in the visual perceptual processing of Chinese characters begin to emerge in middle-grade children.
