  • Title: Bidirectional links in the network of multiplication facts.
    Author: Rusconi E, Galfano G, Rebonato E, Umiltà C.
    Journal: Psychol Res; 2006 Jan; 70(1):32-42. PubMed ID: 15580529.
    Abstract:
    In three experiments, we tested the hypothesis that activation of multiplication operand nodes (e.g., 3 and 8) can occur through presentation of their product (e.g., 24). In Experiments 1 and 2 we found activation of the operands when the product was presented as a cue in a number-matching task. In Experiment 3, activation also occurred in a parity-matching task, where the product (24) was not relevant to the parity matching on its operands (3 and 8). We concluded that bidirectional links exist among the operands and their product for multiplication problems and these links can be activated in a purely stimulus-driven manner. We suggest this may constitute the basis for the solution of simple divisions by mediation through the complementary multiplication facts.
