Answer:
chunking, short-term
Explanation:
When you tell an acquaintance your telephone number, you do not recite the digits one by one at a constant rate, as in "3, 3, 7, 2, 3, 4, 8, 3, 9, 2." Rather, you might say, "3, 3, 7 . . . 2, 3, 4 . . . 83, 92." This exemplifies chunking, a strategy to enhance short-term memory.
This, in turn, helps to remember the number.
