ABSTRACT

We compare poor-performing and normal-performing decoders’ processing times on real words, pseudo-homophones, and nonwords (Study 1), and evaluate how a processing time difference is associated with rates of decoding development (Study 2). Over 800 sixth and seventh graders took an online reading component battery, which included a decoding test, four times in three consecutive years. Study 1 indicates that poor decoders were generally slower than their peers in processing real words and pseudo-homophones, but they spent shorter time than their peers when decoding nonwords that were novel to them, resulting in a significant interaction. In Study 2, longitudinal modeling reveals that the time students spent decoding novel words positively predicted decoding development. These results are consistent with the hypothesis that poor decoders may be trapped in a vicious cycle: poor decoding skill combined with less time spent attempting to decode novel words interferes with decoding development.

摘要

我们比较了真实单词，伪谐音符号和非单词上性能不佳和正常性能的解码器的处理时间（研究1），并评估了处理时间差异与解码发展速度之间的关系（研究2）。超过800名六年级和七年级学生连续三年参加了一次在线阅读成分电池，其中包括一次解码测试。研究1表明，较差的解码器在处理实词和伪谐音器时通常比同等速度慢，但花费的时间较短在解码对他们来说很新颖的非单词时比同龄人花费更多的时间，从而导致了重大的互动。在研究2中，纵向建模揭示了学生花在解码新单词上的时间可以肯定地预测解码的发展。这些结果与以下假设相吻合：不良的解码器可能陷入一个恶性循环：不良的解码技术加上较少的尝试解码新单词的时间会干扰解码的发展。
