 A test in which stimuli are briefly exposed in either the left or right visual half field.

Tachistoscope Test

Using a tachistoscope test, stimuli is presented to either the left or right visual field for less than 150 milliseconds to have the input only in the contralateral hemisphere.

These studies confirm the general division of labor between the hemispheres. The left hemisphere(right visual field) is better at processing verbal stimuli (letters and words). The right hemisphere (left visual field) is better at processing non-verbal stimuli (faces, geometric words, etc.). Simple visual detection is performed by both hemispheres.

In healthy individuals, studies on brain asymmetry focus primarily on hearing and vision. By directing auditory or visual stimuli to a single hemisphere, researchers can infer functional specializations based on the participants' responses.

In a task where a participant is told to identify/recall the different sounds coming through each ear, most people will identify sounds that come from the right ear more accurately than the right ear. (Note: 50%of left-handers experience the reverse, which is a left-ear advantage).
