We propose that such a directional advantage may be due the overwhelming reading experience in the horizontal direction. Writing orientation is highly flexible for Traditional Chinese sentences. We compare horizontal and vertical eye movements during reading of such sentences and provide first evidence of a text-orientation effect on eye-movement control during reading. In addition to equivalent reading speed in both directions, more fine-grained analyses demonstrate a tradeoff between longer fixation durations and better fixation locations in vertical than in horizontal reading. Our results suggest that with extensive reading experience, Traditional Chinese readers can generate saccades more efficiently in vertical than in horizontal direction.}, language = {en} } @article{YanPanLaubrocketal.2013, author = {Yan, Ming and Pan, Jinger and Laubrock, Jochen and Kliegl, Reinhold and Shu, Hua}, title = {Parafoveal processing efficiency in rapid automatized naming a comparison between Chinese normal and dyslexic children}, series = {Journal of experimental child psychology}, volume = {115}, journal = {Journal of experimental child psychology}, number = {3}, publisher = {Elsevier}, address = {San Diego}, issn = {0022-0965}, doi = {10.1016/j.jecp.2013.01.007}, pages = {579 -- 589}, year = {2013}, abstract = {Dyslexic children are known to be slower than normal readers in rapid automatized naming (RAN). This suggests that dyslexics encounter local processing difficulties, which presumably induce a narrower perceptual span. Consequently, dyslexics should suffer less than normal readers from removing parafoveal preview. Here we used a gaze-contingent moving window paradigm in a RAN task to experimentally test this prediction. Results indicate that dyslexics extract less parafoveal information than control children. We propose that more attentional resources are recruited to the foveal processing because of dyslexics' less automatized translation of visual symbols into phonological output, thereby causing a reduction of the perceptual span. This in turn leads to less efficient preactivation of parafoveal information and, hence, more difficulty in processing the next foveal item.}, language = {en} } @article{YanRisseZhouetal.2012, author = {Yan, Ming and Risse, Sarah and Zhou, Xiaolin and Kliegl, Reinhold}, title = {Preview fixation duration modulates identical and semantic preview benefit in Chinese reading}, series = {Reading and writing : an interdisciplinary journal}, volume = {25}, journal = {Reading and writing : an interdisciplinary journal}, number = {5}, publisher = {Springer}, address = {Dordrecht}, issn = {0922-4777}, doi = {10.1007/s11145-010-9274-7}, pages = {1093 -- 1111}, year = {2012}, abstract = {Semantic preview benefit from parafoveal words is critical for proposals of distributed lexical processing during reading. Semantic preview benefit has been demonstrated for Chinese reading with the boundary paradigm in which unrelated or semantically related previews of a target word N + 1 are replaced by the target word once the eyes cross an invisible boundary located after word N (Yan et al., 2009); for the target word in position N + 2, only identical compared to unrelated-word preview led to shorter fixation times on the target word (Yan et al., in press). A reanalysis of these data reveals that identical and semantic preview benefits depend on preview duration (i.e., the fixation duration on the preboundary word). Identical preview benefit from word N + 1 increased with preview duration. The identical preview benefit was also significant for N + 2, but did not significantly interact with preview duration. The previously reported semantic preview benefit from word N + 1 was mainly due to single- or first-fixation durations following short previews. We discuss implications for notions of serial attention shifts and parallel distributed processing of words during reading.}, language = {en} } @article{ShuZhouYanetal.2011, author = {Shu, Hua and Zhou, Wei and Yan, Ming and Kliegl, Reinhold}, title = {Font size modulates saccade-target selection in Chinese reading}, series = {Attention, perception, \& psychophysics : AP\&P ; a journal of the Psychonomic Society, Inc.}, volume = {73}, journal = {Attention, perception, \& psychophysics : AP\&P ; a journal of the Psychonomic Society, Inc.}, number = {2}, publisher = {Springer}, address = {New York}, issn = {1943-3921}, doi = {10.3758/s13414-010-0029-y}, pages = {482 -- 490}, year = {2011}, abstract = {In alphabetic writing systems, saccade amplitude (a close correlate of reading speed) is independent of font size, presumably because an increase in the angular size of letters is compensated for by a decrease of visual acuity with eccentricity. We propose that this invariance may (also) be due to the presence of spaces between words, guiding the eyes across a large range of font sizes. Here, we test whether saccade amplitude is also invariant against manipulations of font size during reading Chinese, a character-based writing system without spaces as explicit word boundaries for saccade-target selection. In contrast to word-spaced alphabetic writing systems, saccade amplitude decreased significantly with increased font size, leading to an increase in the number of fixations at the beginning of words and in the number of refixations. These results are consistent with a model which assumes that word beginning (rather than word center) is the default saccade target if the length of the parafoveal word is not available.}, language = {en} }
