چکیده انگلیسی


- We investigate eye movement patterns of Chinese dyslexic and normal children.
- Group difference increases as words get longer in single fixation landing position.
- Incoming saccade amplitudes are longer in single than in first of multi-fixations.
- Launch sites are closer in single fixations than in first of multi-fixations.
- Chinese children's saccade-target selection is affected by high level processing.

This study investigates the eye movements of dyslexic children and their age-matched controls when reading Chinese. Dyslexic children exhibited more and longer fixations than age-matched control children, and an increase of word length resulted in a greater increase in the number of fixations and gaze durations for the dyslexic than for the control readers. The report focuses on the finding that there was a significant difference between the two groups in the fixation landing position as a function of word length in single-fixation cases, while there was no such difference in the initial fixation of multi-fixation cases. We also found that both groups had longer incoming saccade amplitudes while the launch sites were closer to the word in single fixation cases than in multi-fixation cases. Our results suggest that dyslexic children's inefficient lexical processing, in combination with the absence of orthographic word boundaries in Chinese, leads them to select saccade targets at the beginning of words conservatively. These findings provide further evidence for parafoveal word segmentation during reading of Chinese sentences.
