If two symbols were presented simultaneously, one on either side of the visual field (e.g. a dollar sign on the left and a question mark on the right) and the participant was required to draw with their left-hand (shielded from their own view) what they had seen, how would they respond?
They would draw the left visual field symbol (a dollar sign)
They would draw the right visual field symbol (a question mark)
They could not draw anything
They could not name anything
