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 at which one can orient one's eye to a stimulus has also been highly correlated with overall health.
B: The speed in which a person orients his or her eyes towards a stimulus is a skill that cannot be modified by experience.
C: 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.
D: The ability of scientists to measure a person's IQ depends on whether that person is literate.
