Relative saccade length distributions reveal differences in gaze dynamics. Saccadic planning is more constrained during reading than shape-scanning, offering new insights into visual behavior during language processing.

Area of Science:

  • Cognitive Neuroscience
  • Psychology
  • Computational Linguistics

Background:

  • Human gaze behavior offers insights into cognitive processes during task execution.
  • Reading involves visual sampling and language processing, influencing visual behavior.
  • Existing measures of visual behavior are stimulus-dependent, limiting understanding of stimulus-independent differences.

Purpose of the Study:

  • To investigate stimulus-independent differences in gaze dynamics during reading and shape-scanning.
  • To explore the utility of relative saccade length distributions as a novel measure for studying visual behavior.
  • To consolidate findings on the vision-language interface and its neural underpinnings.

Main Methods:

  • A within-subject design comparing gaze behavior during text reading and shape-scanning.

  • Analysis of relative saccade length distributions in target and non-target directions.
  • Spatial matching of text and shape stimuli.

    • Main Results:

    • Relative saccade length distributions reveal similarities and differences in gaze dynamics between reading and shape-scanning.
    • Saccadic planning is more constrained during reading, indicated by more consistent saccade lengths in the target direction.
    • Consistency of eye movements opposite the target direction did not differ between conditions.

    Conclusions:

    • Relative saccade lengths offer a novel, stimulus-independent measure for investigating visual behavior during reading.
    • Findings support neurocognitive models of the vision-language interface.
    • Analyzing gaze dynamics via relative saccade lengths can provide insights into task-specific processing and cross-task similarities.
