Based on the facts, what can be inferred about the relationship between poverty and brain development?

• A. Physiological differences exist in the brains of children raised in poverty.
• B. Brain development is unaffected by poverty.
• C. Poverty improves cognitive outcomes with more stimulation.
• D. Nutritional deficits do not affect brain function.

Answer: (A)

Poverty-related environments expose children to stress, variable nutrition, and limited cognitive stimulation, all of which can influence how the brain develops. These environmental factors can shape brain physiology, affecting areas involved in memory, attention, and executive function, as well as white matter connectivity. Because of these influences, it’s reasonable to infer that physiological differences can exist in the brains of children raised in poverty compared with those from more advantaged backgrounds. The other statements conflict with what we know about how stress and nutrition influence neural development, which is why they’re not supported by the facts.
