Abstract : Current theories of mental multiplication elicit two questions: (1) Do the same processes underlie answer production and answer verification, and (2) Does any theory centered around a single strategy suffice to explain the underlying mechanisms for these tasks? This study involved addition of retrospective protocols to a verification task, in two experiments. The patterns of effects for reaction times (RT) and errors in both experiments were similar to Campbell's (1991) findings, suggesting that the addition of the protocols did not significantly alter the task. Analysis of the protocols provided evidence that retrieval of the correct answer from memory and then comparison to the answer given was the modal strategy reported in both experiments but was not reported for 100% of the trials. These findings imply that the same processes that underlie production are involved. Furthermore, the use of protocols can facilitate differentiating what strategies are involved and provide evidence that any theory of this skill assuming one strategy will likely be incomplete.
