Abstract

Little is known about how word recognition processes, such as decoding, change when reading fluency improves during the school year. Such knowledge may have practical importance by determining which aspects of reading are most malleable at a certain age and reading level. The development of word-recognition subprocesses of third- and fourth-grade Finnish students (n = 81) with variable reading fluency was explored from longitudinal (6-month) text reading eye-tracking data. Generic development of the word recognition system was assessed from longitudinal changes in first fixation, average refixation durations and the number of first-pass fixations. The development of orthographic word representations and decoding was studied by examining the longitudinal changes in word frequency and word length effects, respectively. According to the results, the gain in reading fluency was mainly associated with decreases in first fixation and refixation durations. These decreases, in turn, inhibited the reduction in the number of fixations. However, students who could overcome this inhibitory effect, that is, by reading both with shorter fixation durations and with fewer fixations, developed most in reading fluency. The results seem to indicate that reading fluency development is driven by increased efficiency in representing letter strings in working memory. Over time, this development may lead to fewer fixations made into a word and, thus, more letters processed during each fixation.

阅读流畅性发展机制的眼动研究
在学习期间,当阅读流畅性提高时,单词识别过程(如解码)是如何变化的,我们知之甚少。这些知识在确定阅读的哪些方面在特定的年龄和阅读水平上是最具可塑性的方面,可能具有实际的重要性。通过纵向(6个月)文本阅读眼动追踪数据,探讨了芬兰三年级和四年级学生(n = 81)不同阅读流畅性的单词识别子过程的发展。从第一次注视的纵向变化、平均再注视时间和第一次注视的次数来评估单词识别系统的一般发展。通过对词频和词长影响的纵向变化,研究了正字法单词表征和解码的发展。结果表明,阅读流畅性的提高主要与首次固定和再固定时间的减少有关。这些减少反过来又抑制了注视次数的减少。然而,能够克服这种抑制效应的学生,即通过较短的注视时间和较少的注视时间来阅读,在阅读流畅性方面发展最快。研究结果似乎表明,阅读流畅性的发展是由工作记忆中表示字母串的效率提高所驱动的。随着时间的推移,这种发展可能会导致对一个单词的注视更少,因此,每次注视时处理的字母更多。

期刊介绍: Cognitive Development contains the very best empirical and theoretical work on the development of perception, memory, language, concepts, thinking, problem solving, metacognition, and social cognition. Criteria for acceptance of articles will be: significance of the work to issues of current interest, substance of the argument, and clarity of expression. For purposes of publication in Cognitive Development, moral and social development will be considered part of cognitive development when they are related to the development of knowledge or thought processes.
