Individual differences in reading subprocesses: relationships between reading ability, lexical access, and eye movement control.

This study examines the relationship between individual reading subprocesses and general reading ability in college students. The reading measures included eye movements while reading a passage, lexical decision latencies, comprehension, and vocabulary size. The results indicate that a distinct relation exists between reading speed and fixation behaviour associated with regressions through a text. About half the variability in comprehension scores can be predicted by subjects' performance on nonword lexical decisions, gaze durations, and vocabulary scores. These findings are discussed with reference to past studies using similar reading measures.
