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

点击翻译按钮获取中文摘要

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.
