Question

Quizplus · Accepted Answer

Studies have shown that when visual stimuli are presented off the foveal fixation point, subjects are faster in shifting their attention to an expected point than to an unexpected point. This is known as the "validity effect." Therefore, Option A is the correct answer. Option B is incorrect because there is a difference in the speed of shifting attention. Option C is also incorrect because shifting attention is possible. Option D is incorrect because the accuracy of identifying the stimulus was not mentioned in the question.
