McCollough aftereffects in strabismus and amblyopia

Probing Unconscious Visual Processing with the McCollough Effect

“…An experiment by Seaber and Lockhead (1989) provides some evidence for this. They studied both normal and strabismic 3 subjects using the same induction regime described above and found that, although normal subjects reported both the monocular and binocular aftereffects, strabismic subjects reported only the monocular aftereffects.…”

“…Despite the absence of interocular transfer, a ''binocular'' McCollough effect can be demonstrated under certain induction conditions (Seaber & Lockhead, 1989;Vidyasagar, 1976). For example, subjects might be induced with red-and-black vertical and green-and-black horizontal gratings with both eyes open.…”
