Research for understanding underlying mechanisms of source memory deficits in old adults

一系列实验探索了为什么老年人在源记忆中表现出不成比例的缺陷，而不是项目记忆的潜在机制。本研究的结果表明，源记忆的衰退部分是由于与年龄相关的短期和/或长期记忆中的特征结合缺陷和与年龄相关的记忆任务中的注意控制缺陷。此外，研究表明，老年人源记忆退化的一个最重要的隐藏因素似乎是编码和/或提取过程的速度变慢。有必要进行进一步的研究来检验这一假设。

A series of experiments explored underlying mechanisms of why old adults show disproportional deficits in source memory as opposed to item memory. The results of this study indicate that the source memory deterioration would be partly due to the age-related feature binding deficit in short and/or long-term memory and the age-related attention control deficits in memory tasks. Furthermore, the study showed one of the most important hidden factors involved in the source memory deterioration seems to be the slowing speed of processes in encoding and/or retrieval for old adults. A further study is necessary to examine this hypothesis.
