Campbell and Reynvoet (2009) found that time to name a single-digit target was about 8 ms faster if preceded by a near prime (±1) compared to a far prime (at least ±3) when prime-digit pairs were interleaved with number comparisons (9↑3; name larger) and not when they were interleaved with multiplication problems (9×3; state product). This is consistent with the claim by previous researchers that magnitude comparison can enable a semantic pathway for digit naming whereas number-fact retrieval can inhibit it. To pursue this, the current study compared priming in the context of multiplication production (9×3=?) versus multiplication verification (e.g., 9×3=24, true or false). Multiplication production, but not verification, may inhibit semantic digit naming to reduce naming-related interference with verbal number production. Indeed, semantic priming of digit naming occurred only in verification and not production blocks. This supports the conclusion that multiplication production can inhibit semantic mediation of digit naming, which is enabled in other number processing tasks (e.g., comparison, verification) that do not compete with naming for verbal number production processes.
坎贝尔和雷诺沃特（2009年）发现，当质数数字对与数字比较（9↑3；说出较大的数）交错排列时，与远质数（至少±3）相比，在接近质数（±1）之前命名个位数目标的时间要快约8毫秒；而当它们与乘法问题（9×3；说出乘积）交错排列时则不然。这与之前研究人员的观点一致，即大小比较可以为数字命名开启一条语义通路，而数字事实检索则会抑制它。为了探究这一点，当前的研究比较了乘法运算（9×3=？）与乘法验证（例如，9×3=24，对或错）情境下的启动效应。乘法运算而非验证，可能会抑制语义数字命名，以减少与言语数字生成相关的命名干扰。事实上，数字命名的语义启动仅发生在验证环节，而不是运算环节。这支持了这样的结论：乘法运算会抑制数字命名的语义中介，而在其他不与言语数字生成过程中的命名相竞争的数字处理任务（如比较、验证）中，语义中介是可行的。
