Assessment of the Visual Processing Carried Out by Each Hemisphere

question 67

Multiple Choice

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?

• 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.
