Native Japanese speakers were timed to judge the numerically larger of two numbers, written either in Kanji (an ideographic script) or in Kana (a syllabic script). For Kanji, irrelevant variations in the physical size of the numbers speeded reaction time in one condition and slowed it in another. Such variations only slowed processing for Kana, except when subjects had previously performed with Kanji. For both scripts, reaction time varied with the numerical difference between the two numbers but not in an identical manner. The implications of the findings are considered.
以日语为母语的人被要求判断两个数字中数值较大的那个，这两个数字分别用汉字（表意文字）或假名（音节文字）书写。对于汉字，数字物理大小的无关变化在一种情况下加快了反应时间，而在另一种情况下减慢了反应时间。这种变化只会减慢假名的处理速度，除非受试者之前使用过汉字进行测试。对于这两种文字，反应时间都随两个数字之间的数值差异而变化，但方式并不相同。研究结果的含义也得到了探讨。
