ABSTRACT

Phonological representations are important for reading. In the current work, we examine the relationship between speech-perceptual memory encoding and consolidation to reading ability in skilled adult readers. Seventy-three young adults (age 18–24) were first tested in their word and nonword reading ability, and then trained in the late evening to identify an unfamiliar speech sound contrast (Hindi retroflex-dental). Participants were assessed in their ability to perceive the target contrast immediately before training, after training, and 12 hours later. While perceptual performance on the target at any time point was unassociated with reading ability, overnight changes to the post-training perceptual ability over the 12-hour delay were significantly associated with nonword reading (i.e. decoding) ability, but not real-word reading. These results provide preliminary support for the hypothesis that individual differences in memory processes that update phonological representations following acoustic-phonetic exposure relate to decoding performance, including in adulthood.

语音声音的一夜巩固预测熟练成人读者的解码能力

摘要

语音表征对于阅读很重要。在目前的工作中,我们研究了语言感知记忆编码和巩固与熟练成人读者阅读能力之间的关系。73 名年轻人(18-24 岁)首先接受了单词和非单词阅读能力的测试,然后在深夜接受训练以识别不熟悉的语音对比(印地语卷舌-牙音)。评估参与者在训练前、训练后和 12 小时后感知目标对比度的能力。虽然在任何时间点对目标的感知性能与阅读能力无关,但在 12 小时延迟内训练后感知能力的夜间变化与非单词阅读(即解码)能力显着相关,但与真实单词阅读无关。
