(A) Example dichoptic stimulus. (B) Participants reported binocular perceived contrast using their thumb and forefinger to move the throttle lever of a joystick. (C) Trial schematic indicating contrast modulation in each eye over time. In half of the trials the fellow eye contrast modulated at 1/8 Hz and amblyopic eye at 1/6 Hz (left panel) or vice versa (right panel). Example monoptic portions embedded in the trial are shown in grey, these regions differed across each trial. (D) Example mean time-courses averaged across all 14 trials per condition (dichoptic periods only), with model fits (based on the full dataset), for typical participants from the control, amblyopic and non-amblyopic strabismus with equal vision groups.
