摘要
三个实验考察二语者语素知识水平对二语语素复杂词(派生词)加工的影响。被试的母语为汉语,第二语言为英语,根据语素知识测验的分数划分出高、低语素知识水平的两组被试。实验1采用掩蔽启动范式下的词汇判断任务,结果发现仅有高语素知识的被试出现了语素启动效应。这说明高语素知识被试对语素复杂词进行了分解加工。实验2采用自定步速移动窗口范式,考察高、低语素知识被试组在句子阅读过程中对语素复杂词的加工机制。结果发现,相比于加工句子中单语素词,高语素知识组在加工句子中的语素复杂词时出现了显著的加工代价,低语素知识组未出现加工代价。这说明高语素知识组被试对派生词进行了分解加工,低语素知识组采用了整词的加工机制。实验3采用了ERP技术,比较两组被试在句子阅读中加工正确和违反派生规则词汇时脑电成分的差异。结果发现,高语素知识者在加工派生规则违反词汇时诱发了P600,低语素知识者诱发了N400。结果表明,高语素知识组被试对派生词采用分解加工的机制,而低语素知识组被试采用了整词的加工机制。三个实验的结果表明,二语者语素知识是影响二语语素复杂词加工的重要因素,语素知识水平高的二语者对派生词进行了基于规则的分解加工,语素知识水平低的二语者采用了整词匹配的加工机制。本研究首次发现了二语者语素知识水平对二语语素复杂词加工的影响。
The present study investigated whether the morphological knowledge affects the online English morphological processing in Chinese-English bilinguals. Three experiments were conducted using derivational words. Experiment 1 employed a masked priming paradigm. Forty L2 learners were divided into two groups based on their score in the morphological knowledge test. The lexical decision task was used. The experiment 1 found the significant effect of morphological knowledge. To be specific, full-priming effect was found in the group with high morphological knowledge while no priming effect in the group with low morphological knowledge. These findings suggest that the group with high morphological knowledge relies on rule-based decomposition in online morphological processing, while the group with low morphological knowledge relies more on memory-based whole-word storage. Experiment 2 employed a self-paced moving window reading paradigm to test the difference between the two groups with high and low morphological knowledge. Derivational words or simple words were embedded in semantically plausible sentences. Both groups were asked to finish a reading comprehension task. Only the group with high morphological knowledge showed a significant processing cost in reading derivational words compared with monomorphemic words. Previous findings suggested that the morphologically complex words go through the process of decomposition and this needs extra processing time which is so called processing cost. The processing cost in the group with high morphological knowledge suggests that they decompose the derivational words based on rules, which prolongs the processing time. In Experiment 3, we combined the event-related brain potential technique with morpho-syntactic violation paradigm to investigate the cognitive mechanism of the two groups with high and low morphological knowledge in a sentence reading task involving morphological processing. Correctly and incorrectly formed derivational words were embedded in semantically plausible sentences. We found that violations of derivational morphology elicited an increased N400 component in the group with low morphological knowledge. For the group with high morphological knowledge, a significant P600, but no N400 component was elicited. This finding suggests that the group with high morphological knowledge relies on rule-based decomposition in online morphological processing, but the group with low morphological knowledge employs a whole-word storage mechanism. Based on the three experiments,we conclude that the morphological knowledge of L2 learners plays an important role in online L2 morphological processing. A high level of morphological knowledge helps L2 learners to build a more efficient and native-like morphological processing mechanism, in which they can use a decomposing mechanism in processing morphologically complex words.
