Abstract

Eye movements (EM) during naming alphabetic versus logographic stimuli in children with and without developmental dyslexia (DD) were examined for each stimulus separately to identify conspicuous characteristics that influence naming performance. 40 children (group DD = 18; control group C = 22) were taught Chinese characters. EM were recorded during naming alphabetic words, pictures and Chinese characters. Main variables were articulation latencies, numbers and durations of fixations, secondary variables were fixation locations and error rates. Group DD showed significantly longer latencies and more fixations while reading words, but only insignificantly more fixations while naming pictures and Chinese characters. However, their error rate was significantly higher during naming Chinese characters but correlated neither with severity of phonological deficit nor with visual complexity. Their first fixation was significantly more often on the center of characters, in group C on the left. In both groups, EM variables were influenced by conspicuous features of characters, such as visual complexity, composition and structure. EM variables and scanning behavior while naming Chinese characters indicate holistic processing in the visuo-spatial pathway and were affected by conspicuous features of characters. The higher error rate in group DD could be determined by several factors, without a major role of the phonological deficit.

摘要

对伴有和不伴有发展性阅读障碍（DD）的儿童在命名字母和象形文字刺激时的眼动（EM）进行了分别检查，以确定影响命名表现的明显特征。40 名儿童（DD 组=18；对照组 C=22）学习了汉字。在命名字母单词、图片和汉字时记录了 EM。主要变量是发音潜伏期、注视次数和注视持续时间，次要变量是注视位置和错误率。DD 组在阅读单词时表现出明显更长的潜伏期和更多的注视次数，但在命名图片和汉字时仅略微更多的注视次数。然而，他们在命名汉字时的错误率明显更高，但与语音缺陷的严重程度或视觉复杂性均无相关性。他们的第一个注视点明显更常位于字符的中心，而在 C 组中则位于左侧。在两个组中，EM 变量都受到字符的明显特征的影响，例如视觉复杂性、组成和结构。命名汉字时的 EM 变量和扫描行为表明在视空间通路上进行整体处理，并且受到字符的明显特征的影响。DD 组中较高的错误率可能由几个因素决定，而语音缺陷的作用不大。
