Final answer:
When you move your eye, only the oculocentric direction changes because it is relative to the position of the eyes, which have moved; the egocentric direction remains the same since it is relative to your overall sense of self in the environment.
Step-by-step explanation:
When you move your eye, your perception of where things are in the environment (egocentric direction) does not change because your sense of self in relation to the environment is maintained. However, the location of objects relative to your eyes (oculocentric direction) does change because the eyes are the reference point for this perspective, and they have moved. Therefore, the correct answer to the question of whether the oculocentric and egocentric directions change when you move your eye is (c) only oculocentric changes.
