What is the implied relationship between poverty-related deficits and brain physiology?

• A. There are physiological differences in the brain.
• B. Brain physiology remains the same.
• C. Only behavior is affected.
• D. Poverty leads to increased brain size.

Answer: (A)

The main idea here is that deficits associated with poverty are linked to actual differences in how the brain develops and functions. Factors tied to poverty—like chronic stress, limited nutrition, and fewer opportunities for stimulating experiences—can shape neurodevelopment, leading to measurable changes in brain structure and activity. This means brain physiology can differ from typical development, rather than staying the same, being limited to behavior only, or increasing in size. So the best answer reflects that there are physiological differences in the brain.
