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.
先前的研究表明，声音退化会影响项目在记忆中的编码，尤其是在老年受试者中。我们在此旨在研究最初编码到记忆中的声音退化项目是否更易于随年龄增长而遗忘。年轻和老年参与者接受了一项涉及即时和延迟自由回忆的有声编码和无声编码系列列表学习任务测试。我们发现，退化的听觉输入增加了对先前编码项目的遗忘，尤其是在老年参与者中。我们还发现，工作记忆容量可预测年轻参与者对退化信息的遗忘。在老年参与者中，言语智商是遗忘声音退化信息的最重要预测因素。我们的数据表明，即使经过编码，声音退化信息在老年时尤其容易遗忘。
