If a representation is stored in memory, what cognitive process uses it to perform tasks?

• A. Manipulation
• B. Perception
• C. Encoding
• D. Rehearsal

Answer: (A)

Using stored memory representations to perform tasks requires manipulation of that information. When a representation is in memory, the brain doesn’t just hold it passively; it actively transforms, combines, and applies it to guide actions and problem solving. This manipulation lets you use the stored data to plan, decide, or execute tasks.

Perception is about interpreting incoming sensory input in the moment, not about using stored representations to act. Encoding is the initial step of taking information from the world and putting it into memory, not the step where you actively work with it to do something. Rehearsal helps keep information in working memory, but it’s about maintaining availability rather than using the representation to perform tasks. Manipulation is the process of operating on the stored representation to achieve a goal.
