What Is the Process of Lateralization

The lateralization of brain function is the tendency for some neural functions or cognitive processes to be specialized to one side of the brain or the other. The medial longitudinal fissure separates the human brain into two distinct cerebral hemispheres, connected by the corpus callosum.

What are some examples of lateralization?

The most obvious example of laterality is handedness, which is the tendency to use one hand or the other to perform activities. It is the usual practice to classify persons as right-handed, left-handed, or ambidextrous (two-handed).

What is lateralization and how is it tested?

To examine how language or emotion might be lateralized, a psychologist could use dichotic listening. In this procedure, sounds are presented to the right and left ears at the same time. Participants are most likely to report hearing speech sounds at the right ear and emotional sounds at the left ear.
