Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
In different blocks, text will contain one or more of several dynamic assistive manipulations that are hypothesized to enhance reading: 1) inverting the text at a given position, with instructions for the participant to attend to that location, which simulates a "surrogate fovea" of a patient with central vision loss. 2) horizontally expanding text to alleviate within-word crowding. 3) highlighting the next word with a visible indicator to encourage proper eye movements.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Single Arm
Each participant will participate in several blocks (randomized order), to evaluate performance with and without behavioral gaze-contingent text enhancements.
Gaze-contingent text enhancement
In different testing blocks, the efficacy of the different enhancements will be evaluated, such as inverting the text in a gaze-contingent inverted "spotlight."
