Summary

This summary is machine-generated.

Readers use font size to guide eye movements, even for longer "return-sweep" saccades between lines. This guidance is independent of visual acuity at the target, relying instead on overall text appearance.

Area of Science:

Ophthalmology
Cognitive Psychology
Human-Computer Interaction

Background:

Reading involves small saccades within lines and longer return-sweep saccades between lines.
Previous research shows letter size guides within-line saccades.
The guidance of return-sweep saccades is less understood.

Purpose of the Study:

To investigate if font size influences return-sweep saccade programming.
To determine if font size guidance for return-sweeps depends on visual acuity at the target.
To explore how readers program eye movements for efficient text navigation.

Main Methods:

Participants read text with manipulated font sizes (0.29 vs 0.39° per character).
Line length was also varied (16 vs 26°).
Return-sweep saccade landing positions and under-sweeps were measured.

Main Results:

Larger font sizes led to longer return-sweeps and fewer under-sweeps.
Longer line lengths increased return-sweep distance and under-sweep proportion.
No interaction was found between font size and line length, indicating font size guidance is independent of target acuity.

Conclusions:

Font size information is utilized when programming return-sweep saccades.
This font size guidance is independent of visual acuity at the saccade target.
Readers likely use global typographic properties for return-sweep programming, optimizing character count on the next line.
