Final answer:
Retrieval is the easiest of the three basic memory tasks as it involves accessing information that has already been stored.
Step-by-step explanation:
The easiest of the three basic memory tasks is retrieval. Retrieval refers to the act of getting information out of memory and back into conscious awareness. It involves accessing information that has been previously encoded and stored. There are three ways to retrieve information: recall, recognition, and relearning. Recall is the ability to access information without cues, while recognition involves identifying information that has been previously learned. Relearning refers to the process of reacquiring knowledge that has been forgotten or is no longer easily accessible. Overall, retrieval is considered to be the easiest of the three memory tasks because it involves accessing information that has already been stored.
