The process by which a child incorporates a stimulus into an existing cognitive structure or schema is

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

Answer: (A)

Assimilation is the process of fitting new experiences into already existing mental frameworks. When a child encounters a stimulus and uses a current schema to interpret it, they’re assimilating. For example, a child who has a schema for “dog” may call any four-legged animal a dog, because they’re applying the existing dog schema to new information. This is different from accommodation, which happens when the child changes the schema itself to fit the new information. Equilibration refers to the broader push to balance assimilation and accommodation, and adaptation is the overall process of adjusting to the environment, involving both.
