Question

Quizplus · Accepted Answer

Studies with adults born blind who have had their sight restored have shown that they have difficulty interpreting and using visual information to mentally represent space. This suggests that early visual experience is important for the full development of the ability to mentally represent space. Option A is incorrect because it assumes that self-locomotion alone is sufficient for perfect development of the ability to mentally represent space, which is not supported by the evidence. Option B is incorrect because it assumes that the stream of visual information accompanying self-locomotion is important only for an individual's current sense of space, which does not take into account the long-term effects of early visual experience. Option D is incorrect because it suggests that individuals who are blind are better able to mentally represent space than those with normal vision, which is not supported by the evidence.
