Interventions
BEHAVIORAL

Binocular visual confusion (unilateral opaque)

"The peripheral target was a horizontally drifting grating measuring 10° by 10°, with a spatial frequency of 1 cycle per degree and a temporal frequency of 3 Hz, and located at 10° above the fixation.~For the binocular visual confusion condition, the non-transparent (opaque) peripheral target will be displayed on only one eye (unilateral opaque display)."

BEHAVIORAL

Unilateral monocular visual confusion (unilateral see-through)

"The peripheral target was a horizontally drifting grating measuring 10° by 10°, with a spatial frequency of 1 cycle per degree and a temporal frequency of 3 Hz, and located at 10° above the fixation.~For the unilateral monocular visual confusion condition, the half-transparent peripheral target will be displayed on only one eye (unilateral see-through display)."

BEHAVIORAL

Bilateral monocular visual confusion (bilateral see-through)

"The peripheral target was a horizontally drifting grating measuring 10° by 10°, with a spatial frequency of 1 cycle per degree and a temporal frequency of 3 Hz, and located at 10° above the fixation.~For bilateral monocular visual confusion condition, the half-transparent peripheral target will be displayed on both eyes (bilateral see-through display)."
