  • Title: Do production and verification tasks in arithmetic rely on the same cognitive mechanisms? A test using alphabet arithmetic.
    Author: Dewi JD, Bagnoud J, Thevenot C.
    Journal: Q J Exp Psychol (Hove); 2021 Dec; 74(12):2182-2192. PubMed ID: 34015986.
    Abstract:
    In this study, 17 adult participants were trained to solve alphabet-arithmetic problems using a production task (e.g., C + 3 = ?). The evolution of their performance across 12 practice sessions was compared with the results obtained in past studies using verification tasks (e.g., is C + 3 = F correct?). We show that, irrespective of the experimental paradigm used, there is no evidence for a shift from counting to retrieval during training. However, and again regardless of the paradigm, problems with the largest addend constitute an exception to the general pattern of results obtained. Contrary to other problems, their answers seem to be deliberately memorised by participants relatively early during training. All in all, we conclude that verification and production tasks lead to similar patterns of results, which can therefore both confidently be used to discuss current theories of learning. Still, deliberate memorization of problems with the largest addend appears earlier and more often in a production than a verification task. This last result is discussed in light of retrieval models.
