【摘要】:數(shù)字包含數(shù)量與順序兩種信息,數(shù)量表示數(shù)目、長短、多少等,順序表示序列結構、等級位置等。本文對中文數(shù)詞數(shù)量和順序加工的神經(jīng)機制進行考察,采用中文數(shù)詞為實驗材料,對蘇州大學22名本科生和研究生進行腦電實驗研究。實驗采用SNARC效應的經(jīng)典實驗范式,分別要求被試對呈現(xiàn)的刺激做數(shù)量比較任務和順序判斷任務,數(shù)量判斷即要求被試判斷呈現(xiàn)的中文數(shù)詞是大于“五”還是小于“五”,順序判斷即要求被試判斷呈現(xiàn)的中文數(shù)詞是在“五”之前還是在“五”之后,記錄被試的腦電數(shù)據(jù)及行為數(shù)據(jù)的反應時和正確率。兩個實驗均為2×2的被試內(nèi)設計,所有實驗采用拉丁方設計。 通過對行為數(shù)據(jù)及腦電數(shù)據(jù)的分析,本研究得到以下結論: (1)中文數(shù)詞的數(shù)量和順序信息均可以產(chǎn)生SNARC效應。 (2)中文數(shù)詞數(shù)量和順序加工均未出現(xiàn)優(yōu)勢腦,左右腦共同參與中文數(shù)詞的數(shù)量和順序加工。 (3)數(shù)量加工的深度大于順序加工,特別是在額區(qū)、中央額區(qū)及中央?yún)^(qū),且300毫秒以后的加工階段,,順序加工在前額區(qū)、額區(qū)的潛伏期提前。
[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.
