Recall latency, recall accuracy rate, and recall confidence were examined in free recall as a function of recall output serial position using a modified Deese-Roediger-McDermott paradigm to test a strength-based theory against the dual-retrieval process theory of recall output sequence. The strength theory predicts the item output sequence to be in the descending order of memory strength. The dual-retrieval process theory postulates two phases in a free recall, a first direct access phase in which items are output verbatim in the weakest-to-strongest order (cognitive triage) and a second reconstructive phase in which reconstructed items are output in the strongestto-weakest order. In three experiments, all three indicators of memory strength (latency, accuracy, and confidence) consistently showed a descending-strength order of recall both for true and false memories. Additionally, false memory was found to be output in two phases and subjects' confidence judgment of their own memory to be unaccountable by retrieval fluency (recall latency).

Research results have been inconsistent regarding the relationship between these two variables. Two theoretical perspectives make different predictions. The first view will be termed memory strength theories (Anderson, 1976(Anderson, , 2005Dosher, 1984;Gillund & Shiffrin, 1984;Norman, 2002; Wixted, Ghadisha, and Vera, 1997). These theories hold that the output sequence of items in a free recall follows the decreasing order of memory strength or activation of the items, i.e., recall output order is from the strongest to the weakest item. Also, according to these theories, the retrieval time for stronger memory is shorter than for weaker memory. The other perspective will be termed the dual-retrieval processes theory (
