The study aimed to explore whether neurophysiological measures of auditory processing in preschoolers can predict Chinese reading after going to school. Mismatch responses (MMRs) to auditory frequency, duration, and temporal pattern deviants were examined in 24 Chinese preschoolers (6.59 +/- 0.25 years old). Reading abilities were tracked in Grades 2 (8.09 +/- 0.29 years old) and 4 (9.65 +/- 0.28 years old). We found that temporal pattern MMRs in preschoolers continuously contributed to Chinese reading fluency in Grades 2 and 4. However, MMRs to frequency or duration deviants did not predict their reading abilities in Grades 2 or 4. These findings suggest that MMRs of basic auditory temporal processing in preliterate children can serve as predictive biomarkers for future Chinese reading acquisition, thus holding promise for identifying Chinese children at risk of dyslexia before formal school education and further guiding early intervention to support their reading development.
