The correct answer is option A, that is, perceptual asymmetries.
Visual perception refers to the procedure of organizing and interpreting visual information. It incorporates the tendency to determine and recognize the distinguishing characteristics of visual images like size, shape, position, orientation, color, and others.
One of the most prominent features is the perceptual asymmetry or variability originating from the brain's perceptual responses to certain visual stimuli and/or to stimuli at the certain specific location of the retina. For example, vertical stimuli are represented and perceived better than oblique stimuli.
Thus, during research with connected brain patients, the researchers study perceptual asymmetry or left/right imbalances between the cerebral hemispheres in auditory or visual processing speed.
