Recall of facts such as the location of the nearest grocery store or the date of the first Moon landing—what scientists call semantic memory—generally doesn’t fade with time.

In psychology, episodic memory is distinguished from semantic memory.

Explicit memory is itself subdivided between episodic memory – the autobiographical record of our experience – and semantic memory, which concerns general knowledge or “textbook learning”.

Factual knowledge, on the other hand, such as the capital of France, is part of semantic memory.

Namely, individuals with a long allele of the 4-GTTLR gene got more right answers on the arithmetic, mental rotation, and semantic memory tasks than did individuals with the short version of the gene.
