Oculomotor and linguistic determinants of reading development: a longitudinal study.

We longitudinally assessed the development of oculomotor control in reading from second to fourth grade by having children read sentences with embedded target words of varying length and frequency. Additionally, participants completed oculomotor (pro-/anti-saccades) and linguistic tasks (word/picture naming), the latter containing the same item material as the reading task. Results revealed a 36% increase of reading efficiency. Younger readers utilized a global refixation strategy to gain more time for word decoding. Linguistic rather than oculomotor skills determined the development of reading abilities, although naming latencies of fourth graders did not reliably reflect word decoding processes in normal sentence reading.
