This study investigated the developmental time course of spoken word recognition in older children using eye tracking to assess how the real-time processing dynamics of word recognition change over development. We found that 9-year-olds were slower to activate the target words and showed more early competition from competitor words than 16-year-olds; however, both age groups ultimately fixated targets to the same degree. This contrasts with a prior study of adolescents with language impairment (McMurray, Samelson, Lee, & Tomblin, 2010) that showed a different pattern of real-time processes. These findings suggest that the dynamics of word recognition are still developing even at these late ages, and developmental changes may derive from different sources than individual differences in relative language ability.
本研究利用眼动追踪技术,调查了大龄儿童口语单词识别的发展时间进程,以评估单词识别的实时处理动态在整个发展过程中是如何变化的。我们发现,与16岁的儿童相比,9岁的儿童激活目标单词的速度较慢,并且在早期受到竞争单词的干扰更多;然而,两个年龄组最终对目标的注视程度相同。这与之前一项针对语言障碍青少年的研究(麦克默里、萨默尔森、李和汤姆林,2010年)形成对比,该研究显示了不同的实时处理模式。这些发现表明,即使在这些较晚的年龄段,单词识别的动态过程仍在发展,而且发展变化的来源可能与相对语言能力的个体差异不同。
