单个阿拉伯数字启动下的数字匹配加工的ERP研究

【摘要】：数字独特的魅力之一就在于它能够以多种不同的外在形式表现出来。世界上绝大多数国家都至少存在两种数字符号,一种是国际上通用的阿拉伯数字,另一种是基于本国语言的数字符号。那么,不同类型的数字符号在进行数字匹配加工时会不会有差异呢?它们的神经机制是不是有所不同呢?本文对单个阿拉伯数字启动下的数字匹配加工进行研究,并结合ERP数据进一步探讨数字匹配加工的神经机制,采用阿拉伯数字、中文数字和英文数字为实验材料,对16名苏州大学本科生和研究生进行行为实验和脑电实验研究。使用数字匹配任务,要求被试对先后呈现的数字做大小匹配判断,记录被试的行为反应时和正确率,同时记录被试的脑电数据。实验采用3×2的被试内设计,所有实验采用拉丁方设计。通过对行为数据和脑电数据的分析,本研究得到以下结论:(1)三种语言条件均出现“快同效应”,N2的潜伏期也表现为匹配的潜伏期要显著早于不匹配条件,且不匹配反应比匹配反应诱发了更负的N2成分。(2)匹配反应和不匹配反应均出现符号效应,且不同符号数字在N2潜伏期上有显著差异,阿拉伯条件的潜伏期最短,英文条件潜伏期最长。(3)各条件下均未出现优势脑区,表明左右脑区共同参与数字匹配任务的加工。
[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.
