Basic cognitive tasks rely on memory

It’s easy not to notice how dependent we are on memory for interpreting the world and performing basic tasks. For example, see this situation from Cognition - Reisberg (p. 5):

Betsy wanted to bring Jacob a present. She shook her piggy bank. It made no sound. She went to look for her mother.

You have to know so much to interpret this! That presents are usually purchased, that piggy banks are where children keep money, that they usually keep coins, etc. All this comes from your memory.

This seems trivial, but it’s not: doing basically anything in the world relies on what you know, and what you know relies on your memory.
