What Eye Movements Reveal About Later Comprehension of Long Connected Texts

Area of Science:

• Cognitive Psychology
• Neuroscience
• Reading Science

Background:

• Reading involves complex coordination between textual features and visual attention.
• Limited research exists on the link between eye movements during reading and subsequent comprehension, especially for extended texts.

Purpose of the Study:

• To investigate the association between eye movement patterns and text comprehension after a reading task.
• To test the weak versus strong association hypotheses regarding eye movements and comprehension.

Main Methods:

• Utilized predictive modeling with regression to forecast comprehension scores from eye movement data.
• Employed participant-level cross-validation across three studies (total N=381) involving long texts.
• Analyzed eye movement features, including fixation count and duration, in relation to comprehension scores.

Main Results:

• Predictive models accurately estimated comprehension scores, supporting the strong association hypothesis (correlations ranging from 0.362 to 0.384).
• Making more, shorter fixations was a consistent predictor of higher comprehension across all studies.
• Models demonstrated generalizability, with predictions transferring across different study datasets.

Conclusions:

• A robust link exists between eye movements during reading and subsequent comprehension of long texts.
• Findings integrate theories of low-level visual processing (eye movements) with higher-order cognitive text processing.
• Eye movement patterns offer valuable insights into reading comprehension mechanisms.
