Which principle emphasizes that each brain is unique?

• A. The brain processes parts and wholes
• B. Each brain is unique
• C. Learning is easily standardized
• D. Emotions are irrelevant

Answer: (B)

Every learner’s brain is unique, with individual wiring, strengths, and needs shaped by biology and experience. This means people differ in how they process information, how quickly they learn, what kinds of supports help them, and how they best organize and retrieve knowledge. When we recognize this uniqueness, instruction becomes more effective through differentiation, multiple representations (visual, auditory, hands-on), flexible pacing, and ongoing assessment to tailor practice and feedback to each learner.

The other ideas don’t fit with this principle. Thinking learning can be easily standardized ignores real differences among learners. Treating emotions as irrelevant contradicts extensive findings that motivation and affect strongly influence attention, memory, and persistence. And the notion that the brain processes parts and wholes describes a processing style rather than the fundamental truth of individual variability in how brains work.
