Want to know:

Assessment of the visual processing carried out by each hemisphere in split-brain patients usually involves the brief simultaneous presentation of different stimuli to each visual field while the participant fixates on a central point in space. Why is it necessary to ensure that stimulus presentation is brief?Select one:a. If the stimuli were presented over longer intervals, information would be transferred between the hemispheres through the corpus callosum.b. Brief presentation prevents participants from focusing attention on the stimuli.c. The short presentation time is necessary to prevent eye movements, which would redirect information across the visual fields.d. Increasing the presentation time increases task difficulty for split-brain patients.
