Randomized trial shows that phonological and morphological interventions improve reading in children, suggesting distinct neural mechanisms.

To investigate the effects of phonological and morphological interventions on reading disability and related brain changes in Chinese children.
Random assignment of 67 children with reading disability to phonological intervention, morphological intervention, and waitlist groups.
Measurement of cortical thickness and reading improvement pre- and post-intervention.
Assessment of the relationship between socioeconomic status and intervention effectiveness.
Both interventions improved reading abilities in participants.
The phonological intervention increased cortical thickness in the right middle temporal gyrus.
The morphological intervention increased cortical thickness in the left inferior frontal gyrus and superior parietal lobule.

Cao et al. (2026) studied this question.
