Explanation:

• Question 36: The biopsychosocial approach considers biological (nerve damage), psychological (attentional processes), and social (cultural background) factors in understanding health and illness.
• Question 37: The brainstem is the oldest part (basic life functions), followed by the limbic system (emotions, memory), and then the cerebral cortex (higher - order thinking).
• Question 38: Split - brain patients have their corpus callosum (connects the two hemispheres) cut.
• Question 39: Lateralization refers to the specialization of functions in different hemispheres (e.g., face recognition in the right hemisphere).
• Question 40: Caffeine is a stimulant that is most likely to impair sleep.

Answer:

• 36. E. a biopsychosocial approach
• 37. C. brainstem; limbic system; cerebral cortex
• 38. A. corpus callosum
• 39. E. lateralization
• 40. D. caffeine
