【摘要】：數(shù)字獨特的魅力之一就在于它能夠以多種不同的外在形式表現(xiàn)出來。世界上絕大多數(shù)國家都至少存在兩種數(shù)字符號,一種是國際上通用的阿拉伯?dāng)?shù)字,另一種是基于本國語言的數(shù)字符號。那么,不同類型的數(shù)字符號在進行數(shù)字匹配加工時會不會有差異呢?它們的神經(jīng)機制是不是有所不同呢?本文對單個阿拉伯?dāng)?shù)字啟動下的數(shù)字匹配加工進行研究,并結(jié)合ERP數(shù)據(jù)進一步探討數(shù)字匹配加工的神經(jīng)機制,采用阿拉伯?dāng)?shù)字、中文數(shù)字和英文數(shù)字為實驗材料,對16名蘇州大學(xué)本科生和研究生進行行為實驗和腦電實驗研究。使用數(shù)字匹配任務(wù),要求被試對先后呈現(xiàn)的數(shù)字做大小匹配判斷,記錄被試的行為反應(yīng)時和正確率,同時記錄被試的腦電數(shù)據(jù)。實驗采用3×2的被試內(nèi)設(shè)計,所有實驗采用拉丁方設(shè)計。通過對行為數(shù)據(jù)和腦電數(shù)據(jù)的分析,本研究得到以下結(jié)論:(1)三種語言條件均出現(xiàn)“快同效應(yīng)”,N2的潛伏期也表現(xiàn)為匹配的潛伏期要顯著早于不匹配條件,且不匹配反應(yīng)比匹配反應(yīng)誘發(fā)了更負的N2成分。(2)匹配反應(yīng)和不匹配反應(yīng)均出現(xiàn)符號效應(yīng),且不同符號數(shù)字在N2潛伏期上有顯著差異,阿拉伯條件的潛伏期最短,英文條件潛伏期最長。(3)各條件下均未出現(xiàn)優(yōu)勢腦區(qū),表明左右腦區(qū)共同參與數(shù)字匹配任務(wù)的加工。
[Abstract]:One of the unique charm of the number is that it can be expressed in many different external forms. There are at least two kinds of digital symbols in most countries in the world, one is the international Arabic numeral, the other is the digital symbol based on the national language. So, will there be any difference between different types of numeric symbols when they are matched? Do they have different neural mechanisms? In this paper, the digital matching processing under the initiation of single Arabic numerals is studied, and the neural mechanism of digital matching processing is further discussed based on ERP data. Arabic numerals, Chinese numerals and English numerals are used as experimental materials. Behavior and EEG experiments were conducted in 16 undergraduates and postgraduates of Suzhou University. Using the digital matching task, the subjects were asked to match the size of the numbers presented successively, record the behavior response time and correct rate of the subjects, and record the EEG data of the subjects at the same time. The experiment was designed in 3 脳 2 subjects, and Latin square design was used in all experiments. Based on the analysis of behavioral data and EEG data, the following conclusions were drawn: (1) all three linguistic conditions showed "fast-identical effect", and N2 latency also showed that the matching latency was significantly earlier than the mismatch condition, and that the N _ 2 latency was significantly earlier than that of the mismatch condition. (2) both the matching reaction and the mismatched reaction showed symbolic effect, and there was significant difference in N2 latency between different symbol numbers, and the latency of Arab condition was the shortest. (3) there was no dominant brain area in each condition, indicating that the left and right brain regions were involved in the processing of digital matching task together.
