In the context of AP Psychology, which of the following best defines the cerebral cortex?

• A. The outer layer of the brain responsible for higher-order functions such as perception, thought, and decision-making
• B. A bundle of nerve fibers that connects the two hemispheres of the brain
• C. A group of glands that secrete hormones directly into the bloodstream
• D. A structure located at the base of the brain that regulates basic life functions like breathing and heart rate

Answer: (A)

Verified step by step guidance

1. Step 1: Understand that the cerebral cortex is a part of the brain involved in complex mental processes rather than basic life functions or hormone secretion.
2. Step 2: Recognize that the cerebral cortex is the outermost layer of the brain, which is crucial for advanced cognitive abilities.
3. Step 3: Identify the key functions associated with the cerebral cortex, such as perception, thought, decision-making, and voluntary movement control.
4. Step 4: Differentiate the cerebral cortex from other brain structures mentioned, such as the bundle of nerve fibers (corpus callosum), glands (endocrine system), and brainstem (basic life functions).
5. Step 5: Conclude that the best definition of the cerebral cortex is the outer layer of the brain responsible for higher-order functions like perception, thought, and decision-making.
