先前的研究表明，声学退化会影响记忆中的项目编码，尤其是对于老年受试者。我们的目的是调查最初编码到记忆中的声学退化项目是否更容易随着年龄的增长而遗忘。年轻和年老的参与者接受了声码和非声码序列列表学习任务的测试，其中包括立即和延迟自由回忆。我们发现，听觉输入的退化会增加对先前编码项目的遗忘，尤其是对于年长的参与者。我们进一步发现，工作记忆容量可以预测年轻参与者对退化信息的遗忘。在老年参与者中，言语智商是遗忘听觉退化信息的最重要预测因素。我们的数据证明，声学退化的信息即使经过编码，在老年时也特别容易被遗忘。
Prior research suggests that acoustical degradation impacts encoding of items into memory, especially in elderly subjects. We here aimed to investigate whether acoustically degraded items that are initially encoded into memory are more prone to forgetting as a function of age. Young and old participants were tested with a vocoded and unvocoded serial list learning task involving immediate and delayed free recall. We found that degraded auditory input increased forgetting of previously encoded items, especially in older participants. We further found that working memory capacity predicted forgetting of degraded information in young participants. In old participants, verbal IQ was the most important predictor for forgetting acoustically degraded information. Our data provide evidence that acoustically degraded information, even if encoded, is especially vulnerable to forgetting in old age.
