title: Memory for questions and amount of processing.
abstract: Two experiments were carried out on how questions are remembered. Subjects watched a videotape of a series of simple events and then answered 18 questions about these events. The questions were all of the same general syntactic form (e.g., "Did the pencil fall against the jug on A?", where A refers to a particular location). They were designed to elicit three sorts of answer: "yes," "no" because the event took place at another location, and "no" because the event did not take place at all. After the subjects had answered the questions, they were given an unexpected test of their ability to recall them. A difference in the memorability of the questions was predicted on the basis of a procedural theory of comprehension and a hypothesis about memory subjects should cease to process a question when they realize that it concerns an event that did not take place, and such questions should be harder to remember because they are processed to a lesser degree than the other sorts of question. Experiment 1 confirmed the predictions, but its results in part could be accounted for by assuming that subjects recalled the original events and used them as a cue to remembering the questions. Experiment 2 eliminated this explanation by showing that when subjects do not have to answer certain questions, their recall of them is very poor. However, the same differences in the memorability of the three sorts of question were obtained for both answered and unanswered questions.
