Cognitive psychologist: The argument against IQ as a hereditary trait that is fixed throughout one's lifetime ignores the evidence of eye orientation. That is, there is a high correlation between the speed in which a person's eyes orient towards a stimulus and that person's IQ. Specifically, an experiment measured the number of milliseconds subjects required to orient their eyes to the where on a large screen a word was flashed. The study found that the more rapid the response the higher that person's IQ.

Which of the following is an assumption the cognitive psychologist makes?

A:The speed in which a person orients his or her eyes towards a stimulus is a skill that cannot be modified by experience.

B:The ability of scientists to measure a person`s IQ depends on whether that person is literate.

C:Some subjects who have a documented high IQ orient towards a stimulus slower than the average.

D:The screen used in the experiment was so large that subjects had to shift their bodies in order to read the words presented on the screen.

E:The speed at which one can orient one`s eye to a stimulus has also been highly correlated with overall health.
