Topicalization effects in cued recall of technical prose

The perceived topic of a passage should determine what information is given priority in storage effort for later recall. The topic should also determine how effective a later recall cue should be, in that recall should be best if the cue is the same as the passage topic. These issues were studied by investigating cued recall of passages that contained information about two candidate topic items, either of which could be marked as the passage topic by initial mention or the sentence surface subject position. The recall cue was either the item marked as the topic or the nontopic item. If the cue was the topic, recall about the topic item was greater than recall about the nontopic item. If the cue was the nontopic item, recall about the two items was roughly the same, unaffected by the topic marking. But the topic and nontopic cues produced the same overall level of recall. In contrast to the original hypothesis, the results are interpreted as the topic marking and recall cue acting as instructions for what information the subject should emphasize in recall. It is argued that the two-topic passages used in this work are processed differently from the usual one-topic passages in prose memory studies.
