摘要
为探究人们对负数的加工能否影响反应选择,采用自由选择实验范式对17名在校大学生进行研究。该范式要求被试根据自己的喜好按左/右键对数字自由地做出选择。结果发现,仅观看负数并不影响被试对左右键的选择比率以及按压左右键的反应,原因可能是SOA设置过长,导致负数的空间表征未能得到及时利用,此外,也说明人们对负数和正数的心理表征可能存在差异。
In order to explore whether the processing of negative numbers can affect the response selection, 17 college students were studied by free-response paradigm. This paradigm presented participants with low or high digits and then asked them to make one of two keypresses（left or fight） whichever one they felt more comfortable making. It was found that only viewing negative numbers do not affect the ratio of the selected ratio and the reaction of the left and fight keys. The reason may be that the SOA setting is too long, which leads to the spatial representation of negative number can not be used in a timely manner. Beside, it also shows that the mental representation of negative and positive differences that may exist.
