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.
在三个实验中，我们检验了这样一个假设：通过呈现乘法运算数节点（例如3和8）的乘积（例如24），可以激活这些节点。在实验1和实验2中，当乘积作为线索出现在数字匹配任务中时，我们发现了运算数的激活。在实验3中，在奇偶匹配任务中也出现了激活，其中乘积（24）与运算数（3和8）的奇偶匹配无关。我们得出结论，对于乘法问题，运算数与其乘积之间存在双向联系，并且这些联系可以以纯粹由刺激驱动的方式被激活。我们认为，这可能构成了通过互补乘法事实进行中介来解决简单除法问题的基础。
