To assess how the intensity of DR influences brain development, we quantitatively measured parental engagement in DR when children are at 2 years of age. Neural activations in frontal regions associated with EF were evaluated using functional near-infrared spectroscopy when children reached age 5. Our results reveal a significant positive correlation between parental dialogic interaction during shared book reading at age 2 and the activation of key brain regions related to EF \u2013 the bilateral dorsolateral prefrontal cortex and the bilateral inferior frontal gyrus \u2013 during a Dimensional Change Card Sort (DCCS) task at age 5. This correlation persisted even after controlling for maternal education and children\u2019s expressive vocabulary, indicating a robust relationship between early DR experiences and subsequent neural correlates of EF. The results suggest that early DR may help cultivate the neural infrastructure necessary for EF development. By focusing on DR at a young age and assessing neural activity during a classic EF task, the DCCS, our findings contribute additional evidence regarding the role of DR in shaping neural development associated with EF. These results highlight the importance of encouraging interactive DR practices in early childhood, as they not only support language development but also strengthen the neural pathways crucial for cognitive skills essential for academic success.<\/jats:p>","DOI":"10.1371\/journal.pone.0351177","type":"journal-article","created":{"date-parts":[[2026,6,15]],"date-time":"2026-06-15T17:24:34Z","timestamp":1781544274000},"page":"e0351177","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":0,"title":["Dialogic reading at age 2 is linked to frontal activation related to executive function at age 5: An fNIRS study"],"prefix":"10.1371","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8180-8164","authenticated-orcid":true,"given":"Ming Yean","family":"Sia","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chia-Feng","family":"Lu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ovid J.
