What does lateralization of function in the brain imply?

• A. That cognitive processes are equally distributed across both hemispheres
• B. That certain cognitive processes are more dominant in one hemisphere than the other
• C. That brain injuries affect function uniformly across hemispheres
• D. That memory is stored in both hemispheres

Answer: (B)

Lateralization of function in the brain refers to the idea that certain cognitive processes are more pronounced in one hemisphere than the other. This phenomenon is particularly evident in functions such as language, which is typically associated with the left hemisphere in right-handed individuals, and spatial abilities, which are often tied to the right hemisphere. Research has shown that while both hemispheres contribute to a wide range of psychological functions, they do so in a way that is not uniform. For example, people may find that tasks related to verbal skills, such as speaking or writing, are primarily managed by the left side of the brain, while tasks involving visual-spatial processing might be handled more effectively by the right side. By recognizing that certain functions are lateralized, we gain insight into how brain organization affects behavior, cognition, and even the impacts of brain injuries, which may not occur equally across hemispheres due to this specialization.
