有证据表明，命名阿拉伯数字的语义和asemantic路线，但神经心理学分离表明，数字事实检索（2 × 3 = 6）可以抑制数字命名的语义路线。在这里，我们测试的假设，这种抑制应该放慢数字命名，根据减少访问多个路线的原则，将抵消冗余增益（响应时间的优势，预计从平行检索途径）。参与者命名两个个位数，然后进行简单的加法或大小比较（实验1），乘法或大小比较（实验2），乘法或减法（实验3）在相同或不同的数字对。加法和乘法会抑制语义路径，而比较和减法会使语义路径有效。当参与者随后进行加法或乘法相对于比较或减法时，数字命名时间大约慢15 ms，无论是否涉及相同的数字对。实验3中的字母命名控制条件表明，该效应是特定的数字命名。数字事实提取明显抑制阿拉伯数字命名过程。(C)2007 Elsevier B.V.保留所有权利。
There is evidence for both semantic and asemantic routes for naming Arabic digits, but neuropsychological dissociations suggest that number-fact retrieval (2 x 3 = 6) can inhibit the semantic route for digit naming. Here, we tested the hypothesis that such inhibition should slow digit naming, based on the principle that reduced access to multiple routes would counteract redundancy gain (the response time advantage expected from parallel retrieval pathways). Participants named two single digit numbers and then performed simple addition or magnitude comparison (Experiment 1), multiplication or magnitude comparison (Experiment 2), and multiplication or subtraction (Experiment 3) on the same or on a different pair of digits. Addition and multiplication were expected to inhibit the semantic route, whereas comparison and subtraction should enable the semantic route. Digit naming time was approximately 15 ms slower when participants subsequently performed addition or multiplication relative to comparison or subtraction, regardless of whether or not the same digit pair was involved. A letter naming control condition in Experiment 3 demonstrated that the effect was specific to digit naming. Number fact retrieval apparently can inhibit Arabic digit naming processes.
