one measure of memory is recall, which requires you to produce information by searching the memory for it. In aided recall, you are given cues to help you produce the information. In free- recall learning you recall the material in any order in serial learning you recall it in the order it was presented and in paired-associate learning you learn pairs of words so that when the first word is given you can recall the second word. A second measure of memory is recogniting, in which you do not have to produce the information from memory, but must be able to identify it when it is presented to you. In a third measure of memory, relearning, the difference between how long it look to learn the material the first time and how long it takes to learn it again indicates how much you remember. Relearning is generally a more sensitive measure of memory than is recognition, in the sense of showing retention where recognition does not; recognition is generally a more sensitive measure than recall.
