身份信息与位置信息的加工进程及语境预测性的影响 <sup>*</sup>
摘要
<p id="C2">In the process of word recognition, the encoding of letter identity and letter location information plays a vital role. Many English studies found that the letter location information is more flexible than letter identity information. And context predictability has a different effect on letter location and identity information. Chinese word consists of meaningful morpheme, so the encoding of Chinese character identity and location information may have different features from English letter. In present study, we discussed the effect and the time course of predictability on the encoding of Chinese character identity and location information. <p id="C110">In order to explore the morpheme processing, the present study recruited 20 students as participants in experiment 1, and instructed them to do the lexical decision task. We used 5 types of word (original word, transposed non-word, initial substituted non-word, final substituted non-word and unmeaning symbol) as prime words when the prime time is 80 ms, 150 ms and 300 ms. We collected reaction time as the index. We found that the effect caused by transposed non-word is significant from that caused by original word under 80 ms and 300 ms prime condition, but it is opposite under 150 ms condition. <p id="C111">To study the morpheme processing in sentence, 50 participants took part in experiment 2, and was instructed to read high predictability and low predictability sentences. Each sentence included a different target word of 4 conditions which is original word(OR), transposed non-word (TN), first substituted (FS) non-word and end substituted (ES) non-word. The participation’s eye movement was recorded by EyeLink1000 during reading process. The results showed that the TN condition is not significant with FS and ES condition under high-predictability, but it is opposite under low-predictability. <p id="C112">To explore the time course of encoding of Chinese character location and identity information, we used
