Description

Participants are asked to determine their ocular dominance by creating a triangle with their fingers and centering this triangle (with both eyes open) on a far away object. Then they are asked to close their left eye: if the object stays in the center -> right eye dominance if the object moves out of the center -> left eye is dominance
