Which developmental science term is most equivalent to semantic memory?

The correct answer is crystallized knowledge.

Crystallized knowledge refers to the knowledge, information and understandings a person has accumulated in their lifespan. Crystallized knowledge increases with age, because the longer a person has lived, the longer he or she has to learn, acquire knowledge and experience various happenings. Crystallized knowledge is similar to semantic memory, since the latter refers to long-term memory about facts, information and general knowledge.
