This is a variation of the recall portion of a memory task. The subject is not required to explicitly state the items, but instead, they must simply identify which items (from a larger group of items) were on the original list.
For instance, the subject may be read a large list of items and be asked to say "YES" if the item was on the list, and say "NO" if it was not on the list.
This task is slightly easier than the cued or free recall task. The answers provided by the subject fall into 4 categories:
- HITS: These are the responses that correctly identify items as being from the original list when they actually are.
- CORRECT NEGATIVES: These are the responses that correctly state an item as not being on the original list when it actually was not.
- MISSES: These are the responses that fail to identify a word as being from the original list when it was.
- FALSE POSITIVES: These are responses that incorrectly identify items as being from the original list when they were not on that list.
