Imagine that your body, neck and eyeballs are fixed by some
external apparatus (i.e. you can’t move your body, your neck or
eyes). Explain what happens in each of the following
conditions:
(a) You ‘keep’ your eyes fixed (i.e. you don’t try to move
them) and an object moves before your eyes. What do you perceive
(e.g. do you perceive that the object moves?) Why?
(b) While looking at a stationary scene, you try to move
your eyes (but remember, you can’t move them!) What do you
perceive? Do you perceive objects move or not? If yes in which
direction? Why?
(c) An object moves in your visual field. You try to
follow the object with your eyes (but you can’t of course!). What
do you perceive? Does the object appear to move? If yes, slower or
faster? Why?
(Hint: In your answer don’t forget to refer to corollary
discharge model, and retinal image displacement signal, motor
signal and the corollary discharge signal.)
