【摘要】：當(dāng)長(zhǎng)時(shí)間加工或者多次重復(fù)加工特定文字后,對(duì)該文字及其相關(guān)信息加工效率降低的現(xiàn)象稱為文字飽和。該現(xiàn)象在多種文字材料的實(shí)驗(yàn)中都有發(fā)現(xiàn),但其發(fā)生本質(zhì)存在爭(zhēng)論,主要形成以下四種理論解釋:字形飽和、字形語(yǔ)義聯(lián)結(jié)通道飽和、語(yǔ)義飽和及多種飽和方式的結(jié)合,分別提出文字飽和現(xiàn)象可能發(fā)生在文字加工過程中字形加工水平、字形語(yǔ)義聯(lián)結(jié)通道加工水平、語(yǔ)義加工水平和以上多種加工水平的結(jié)合。為了驗(yàn)證多種飽和方式同時(shí)存在的理論假設(shè),研究者采用事件相關(guān)電位技術(shù)(ERP)進(jìn)行兩個(gè)實(shí)驗(yàn),實(shí)驗(yàn)一以韓文文字為實(shí)驗(yàn)材料,通過N170成分監(jiān)控文字加工進(jìn)程中字形加工水平的激活程度,直接反映單純字形加工;實(shí)驗(yàn)二以古文文字為實(shí)驗(yàn)材料,通過N170成分和N400成分監(jiān)控文字加工進(jìn)程中字形加工水平和語(yǔ)義加工水平的激活程度,同時(shí)考察字形加工和語(yǔ)義加工。兩實(shí)驗(yàn)均采用2重復(fù)性(重復(fù)、基線)×2匹配性(是、否)×6重復(fù)水平(6個(gè)區(qū)段)的被試內(nèi)實(shí)驗(yàn)設(shè)計(jì),匹配性僅作快速重復(fù)字形匹配任務(wù)之需,自變量為以區(qū)段表示的重復(fù)水平,因變量為重復(fù)條件R與基線條件B反應(yīng)時(shí)差值DRT、準(zhǔn)確率差值DACC和ERP成分平均波幅差值DAM。實(shí)驗(yàn)一結(jié)果顯示:隨重復(fù)水平增加,反應(yīng)時(shí)差值DRTs無(wú)顯著差異,準(zhǔn)確率差值DACC在第二區(qū)段DACC2和第四區(qū)段DACC4偏低且差異統(tǒng)計(jì)檢驗(yàn)顯著,N170平均波幅差值DAM第四區(qū)段DAM4最高且統(tǒng)計(jì)檢驗(yàn)顯著,即韓文文字字形飽和時(shí)間進(jìn)程為倒U形,峰值出現(xiàn)在第四區(qū)段。實(shí)驗(yàn)二結(jié)果顯示:隨重復(fù)水平增加,反應(yīng)時(shí)差值DRTs無(wú)顯著差異,準(zhǔn)確率差值DACC在第二區(qū)段DACC2和第四區(qū)段DACC4較低且差異統(tǒng)計(jì)檢驗(yàn)顯著,N170平均波幅差值DAM在第二區(qū)段DAM2存在差異,N400平均波幅差值DAMs無(wú)顯著差異,即古文文字字形飽和時(shí)間進(jìn)程為倒U形,峰值發(fā)生在第二區(qū)段,未檢測(cè)到古文文字語(yǔ)義飽和峰值。綜合韓文文字和古文文字飽和現(xiàn)象研究,得出結(jié)論:(1)文字字形飽和時(shí)間進(jìn)程為倒U形;(2)古文文字字形飽和峰值早于韓文文字,即熟悉性影響飽和峰值早晚,熟悉的文字飽和峰值更早。
[Abstract]:When a particular text is processed for a long time or repeatedly, the phenomenon that the processing efficiency of the text and its related information is reduced is called text saturation. This phenomenon has been found in a variety of text materials, but the nature of its occurrence is controversial, mainly forming the following four theoretical explanations: zigzag saturation, zigzag semantic connection channel saturation, semantic saturation and the combination of various saturation modes. It is pointed out that the phenomenon of character saturation may occur in the process of character processing, such as the level of font processing, the processing level of font semantic connection channel, the combination of semantic processing level and the above processing levels. In order to verify the theoretical hypothesis that multiple saturation modes exist at the same time, the researchers used event-related potential technique (ERP) to carry out two experiments. In experiment 1, Korean characters were used as experimental materials. The activation degree of glyph processing level in the process of character processing is monitored by N170 component, which directly reflects the simple glyph processing. In the second experiment, the activation degree of glyph processing level and semantic processing level in the process of character processing was monitored by N170 component and N400 component, and the glyph processing and semantic processing were investigated at the same time. In both experiments, the experimental design of 2 repeatability (repetition, baseline) 脳 2 matching (yes, no) 脳 6 repetition level (6 sections) was adopted, and the matching was only needed for the task of fast repeated glyph matching. The independent variable is the repetition level represented by the section, and the dependent variable is the repetition condition R and the baseline condition B reaction time difference value DRT, accuracy difference DACC and ERP component average amplitude difference DAM. The results of experiment 1 showed that with the increase of repetition level, there was no significant difference in reaction time difference value (DRTs), and the accuracy difference DACC was low in the second section and the fourth section of DACC4, and the difference was significant by statistical test. The DAM4 of the fourth section of the N170 average amplitude difference DAM is the highest and the statistical test is significant, that is, the saturation time process of the Korean character font is inverted U-shaped, and the peak value appears in the fourth section. The results of experiment 2 showed that with the increase of repetition level, there was no significant difference in reaction time difference value (DRTs). The accuracy difference DACC was lower in the second section DACC2 and the fourth section DACC4, and the difference statistical test was significant. The N170 average amplitude difference DAM was different in the second section DAM2. The average amplitude difference DAMs of N400 has no significant difference, that is, the saturation time process of ancient characters is inverted U shape, the peak value occurs in the second section, and no semantic saturation peak value of ancient text is detected. Based on the study of saturation phenomenon of Korean characters and ancient characters, it is concluded that: (1) the saturation time process of characters is inverted U shape; (2) the peak value of glyph saturation in ancient Chinese is earlier than that in Korean, that is, familiarity affects the saturation peak sooner or later, and the saturation peak of familiar text is earlier.
