|Other Abstract||A number of experiments have shown that letter position encoding is very flexible in alphabetic writing systems. A transposed-letter nonword (TL condition), created by transposing two adjacent letters of a word, is perceptually similar to the base word, much more than a replacement-letter nonword (SL condition), in which two corresponding letters are replaced (i.e., the TL effect). There are no spaces or other explicit visual cues between successive words in Chinese texts except for punctuation marks. Given characteristics of Chinese text, character position encoding was examined in our studies.|
We explored how character order information is encoded in two-character words recognition in the first study. Aditionally, whether morpheme boundaries modulate character position encoding is tested. Simple words and compound words were chose as targets. In Experiment 1, we used a masked priming paradigm and in Experiment 2, we embedded target words in sentences and manipulated previews using a boundary paradigm. The prime (in Experiment 1) or preview (in Experiment 2) was identical to the target word (identity condition), a transposition of the two characters of the target word (transposed-character condition, TC condition) or two characters that were different from the characters in the target word (substituted-character condition, SC condition). The results showed that response latencies in the lexical decision task and reading times on the target word region were longer in the SC condition than the TC condition, which were respectively longer than in the identity condition. Therefore, transposed-character effects occurred in Chinese reading. However, morpheme boundaries did not affect character position encoding. In Experiment 3, we explored whether there was different effects between within-morpheme transpositions and across-morpheme transpositions in natural reading conditions. Results found fixation durations in the TC condition was longer than that in the identity condition. A main effect of word type did not appear. To summarize, morpheme boundaries had no effect on character position encoding, and character position encoding occurred at an early stage in word processing.
We explored the effects of word boundaries in Chinese text on the character order encoding in the second study. We used four-character words (the one-word condition) and two two-character words (the two-word condition) as our targets. We used the masked priming paradigm in Experiment 4, embedded the target words into sentences, and then manipulated the previews through the boundary paradigm in Experiment 5. The prime (in Experiment 4) or preview (in Experiment 5) was identity condition, TC condition or SC condition. The reaction times (RTs) and fixation durations on the target word in the TC condition were much longer than those in the identity condition for the two-word condition, but were not significantly different for the one-word condition. Word boundaries were found to affect the character order encoding in Chinese reading. In Experiment 6, we explored whether word boundaries affected character position encoding in natural reading conditions. Results found first fixation duration in the TC condition was longer than the identity condition for two-word targets, while first fixation duration in the TC and identity conditions was not significant for one-word targets.
In summary, character position was encoded and transposed-character effects occurred in Chinese reading. Word boundaries affected character order encoding. Word segmentation occurs at a very early stage of visual word recognition, before or coinciding with the letter position encoding.
