The influence of foveal load on parafoveal processing of N + 2 during Chinese reading

According to the foveal load hypothesis, parafoveal processing is influenced by the difficulty of current foveal processing. It remains unclear whether foveal load may affect the extent of parafoveal processing. This is an important consideration given the evidence that Chinese readers may frequently pre-process word N + 2 when N + 1 is one character. Accordingly, the current study manipulated word frequency to explore the influence of foveal load on parafoveal processing of N + 2 using a 2 (foveal load: high-frequency, low-frequency) × 2 (preview condition: identical preview, pseudo-character preview) within-subject design. Main effects of foveal load were found for the foveal word N, with longer fixations for low- than for high-frequency words and a main effect of preview was also found for N + 2, with longer fixations for pseudo-character preview compared to identical preview. Crucially, there was no interaction between foveal load and preview condition, indicating that parafoveal processing of word N + 2 is not influenced by foveal load during natural Chinese reading.
