Brain lateralization refers to the division of functions between the left and right hemispheres of the brain. Each hemisphere specializes in certain cognitive processes, such as language processing or spatial awareness.
Brain lateralization refers to the idea that certain mental processes or cognitive functions are more dominant in one hemisphere of the brain than the other. Psychologists from biological and cognitive perspectives often study this phenomenon to understand how it affects behavior and cognitive abilities.
Roger W. Sperry's split-brain research in the 1960s provided significant insights into brain lateralization, demonstrating distinct functions of the left and right hemispheres, especially in split-brain patients. Later studies have further explored how lateralization influences language, spatial abilities, and other cognitive processes.
