Answer:
working memory
Step-by-step explanation:
When a middle-school student is able to demonstrate that he/she is able to hear a string of digits (1, 2, 3, 4, etc.) and then repeat the string in reverse order, the child is indicating that he/she is developing: working memory. In working memory, we can store information for a brief period of time. In working memory, the information is analyzed, classified and then stored. The average of digits that a normal adult can recall is 7 items.
