An essay question is a test of memory. a multiple-choice question is a test. recall; recognition recognition; recognition recall; recall recognition; recall

I believe the answer is: recall; recognition
In a recall test, the participant would be exposed to many stimulus, told to wait a minute, and told to recall as much stimulus as possible.
In recognition test, the participant would be implicitly exposed to the stimulus, and would be tested whether they could recognized the same stimulus if presented in a different way.
