Which phrase describes psychology's focus in the 1990s related to brain research?

• A. Psychology's 'decade of the brain'
• B. AI's 'digital renaissance'
• C. The 'neural engineering' era
• D. The 'quantum cognition' era

Answer: (A)

During the 1990s, psychology increasingly linked mental processes to brain activity, marking a concerted push to map how brain function underpins behavior. The best description for this period is psychology’s decade of the brain, a label used to signal a nationwide emphasis on neuroscience as a core part of understanding psychology. Advances in imaging technologies like MRI and PET allowed researchers to observe brain activity as people think, learn, remember, and perceive, fueling the growth of cognitive neuroscience and neuropsychology. The other options don’t fit the era’s broad focus: they point to AI or more niche subfields rather than the widely recognized framing of the decade around brain research.
