Effects of repetition of mental operations on memory for occurrence and origin.
In two experiments, subjects read or generated items at both encoding and retrieval. At test, they were required to decide whether or not the targets were presented initially (recognition), and if so, whether they were initially read or generated (judgments of origin). Recognition for items that were initially generated was enhanced if they were once again generated at test in the same context, but not if they were generated at test without context. These results confirm that memory for occurrence is facilitated by repetition of the initial encoding operations at retrieval. Generating at test resulted in an increase in "generate" responses both for items that were initially generated and for items that were initially read. Overall, there was a decrease in the accuracy of origin discriminations. It is suggested that, when subjects generate at test, they are likely to mistakenly attribute these just-performed operations to be part of the memory trace for that item.
