  Perception and action in Chinese character processing
Chinese characters are similar to morphemes or words in alphabetic languages in their functions, but they are very different in their structures. Unlike English words that are arranged linearly, three levels of hierarchical organization can be distinguished within a constant square-shaped size of a Chinese character. Because Chinese characters are complex visual stimuli and they are also familiar linguistic materials for Chinese readers, they serve as an excellent tool to investigate the sensorimotor processes on the one hand and the knowledge representation on the other. We have approached issues as such by conducting both behavior and fMRI experiments. Behavioral data revealed the important aspect of character structure and how familiarity affects our perception of Chinese characters. However, in most conditions Chinese readers did not differ in their perception from non-readers, other than the one that particularly imposes the perception-for-action route in our visual brain. In particular, results from fMRI studies confirmed the importance of the medial occipital gyrus and the intraparietal sulcus in the involvement of grouping of a perceived orderly writing action.
