What is the term for the balance between assimilation and accommodation?

• A. Adaptation
• B. Assimilation
• C. Accommodation
• D. Equilibration

Answer: (D)

Equilibration is the process of balancing assimilation and accommodation to reach cognitive stability. Assimilation uses existing schemas to interpret new information, while accommodation adjusts those schemas or creates new ones in light of evidence that doesn’t fit. When something doesn’t fit what a learner already thinks, disequilibrium motivates a shift between interpreting the new input through current ideas and modifying those ideas, until a stable understanding emerges. For example, a child who believes all four-legged animals are dogs encounters a cat; this mismatch prompts refining the dog category and forming a separate cat category, restoring balance. This ongoing balancing act drives growth in understanding.
