Answer:
Chunking
Step-by-step explanation:
Chunking is a term that refers to the process of taking individual pieces of information (chunks) and grouping them into larger units. This is a memory strategy that helps us memorize larger units of information by grouping them into smaller pieces.
When we take each piece of information into the larger whole, it is easier to remember the whole than try to remembering by itself.
In this example, Megan can recall her friend's number even though it contains 15 digits. The strategy she used to remember is that she split the digits into smaller groups of three each. We can notice that Megan took these smaller pieces of information to memorize the larger number. Thus this process is called chunking.
