词汇获得年龄效应的眼动研究

采用两个实验考察了获得年龄因素在汉语词汇识别中的作用。实验一采用经典的词汇判断任务考察了获得年龄和词频因素在词汇判断中的作用,结果发现获得年龄和词频两个因素均影响词汇识别。实验二采用阅读句子任务,通过实时记录的眼动追踪技术进一步考察了在有语境的情况下,获得年龄和词频因素在词汇加工中的作用。结果发现,在阅读句子任务中,词汇获得年龄和词频因素都在词汇加工中起作用,二者存在交互作用,晚获得词存在词频效应。两个实验的结果均支持了在汉语词汇识别中,存在获得年龄效应。

AN EYE MOVEMENT STUDY ON AGE OF ACQUISITION EFFECT

Two experiments were conducted to explore the locus of the age of acquisition effects in the word identification.In Experiment 1,classic lexical decision task was used to examine how word′s age of acquisition and word frequency contribute to word recognition.The results found that the age of acquisition and frequency affected word identification.In Experiment 2,participants were asked to read the sentences which contained target words that varied in the age of acquisition and word frequency but other factors were controlled.,eye movements were recorded as participants read sentences to further explore the roles of age of acquisition and word frequency in word recognition.The results showed that word′s age of acquisition and word frequency played an important role in the Chinese word processing.The present experiment also found a tendency for the frequency effect to be slightly larger for later-acquired than for earlier-acquired words.Results from these two experiments converged to demonstrate that it is in being for the effect of the age of acquisition in the task of word processing.
