【摘要】：数字包含数量与顺序两种信息，数量表示数目、长短、多少等，顺序表示序列结构、等级位置等。本文对中文数词数量和顺序加工的神经机制进行考察，采用中文数词为实验材料，对苏州大学22名本科生和研究生进行脑电实验研究。实验采用SNARC效应的经典实验范式，分别要求被试对呈现的刺激做数量比较任务和顺序判断任务，数量判断即要求被试判断呈现的中文数词是大于“五”还是小于“五”，顺序判断即要求被试判断呈现的中文数词是在“五”之前还是在“五”之后，记录被试的脑电数据及行为数据的反应时和正确率。两个实验均为2×2的被试内设计，所有实验采用拉丁方设计。通过对行为数据及脑电数据的分析，本研究得到以下结论：（1）中文数词的数量和顺序信息均可以产生SNARC效应。（2）中文数词数量和顺序加工均未出现优势脑，左右脑共同参与中文数词的数量和顺序加工。（3）数量加工的深度大于顺序加工，特别是在额区、中央额区及中央区，且300毫秒以后的加工阶段，，顺序加工在前额区、额区的潜伏期提前。
[Abstract]:Contains the number and order of two kinds of digital information, the number indicates the number, length, number, sequence structure and sequence level location. The paper studies the neural mechanism of Chinese numeral and order processing, using Chinese numerals as experimental materials, conduct research on EEG in Soochow University 22 undergraduate and graduate students. The classical experiment the experimental paradigm using the SNARC effect, respectively. The subjects were required to do the task of quantity comparison and order judgment task on the number of stimuli, the judgment that the subjects were required to judge the Chinese numeral is greater than five or less than five, in order to judge the subjects were required to judge the present Chinese numeral is "Five" before or in the "Five" after the EEG data and behavioral data recorded by the reaction time and correct rate. Two experiments were 2 * 2 within subject design, all the Latin square design was adopted in this study.
Through the analysis of the behavioral data and EEG data, this study got the following conclusions:
(1) Chinese numeral number and sequence information can produce SNARC effect.
(2) the advantage of the brain did not appear Chinese numeral and order processing, to participate in the left and right brain Chinese numeral number and order processing.
(3) the number of processing depth is larger than the order processing, especially in the frontal area, central frontal and central regions, and 300 milliseconds after the processing stage, order processing in the prefrontal area, the frontal region of the incubation period in advance.
