目的 探讨情节记忆年老化的选择性及其变异性与焦虑之间的关系。方法 筛选老年和青年高、低特质焦虑者完成记忆任务。以20个动宾词组为记忆的内容，以听或做动作为记忆的来源。结果 (1)老年组来源记忆和内容记忆均显著差于青年组，但并未发现来源记忆比内容记忆对年老化更为敏感；(2)实验情境诱发的焦虑情绪干扰了老年组记忆操作，但对青年组没有不利影响，甚至促进其条件性来源记忆成绩。结论 (1)相对于内容记忆而言，来源记忆年老化并不存在选择性受损； (2)焦虑与情节记忆年老化的变异性存在联系，提示采取情绪干预可能会改善老年记忆功能。%Objective To investigate the select ivity of episodic memory aging and its variability in relation to anxiety.Methods The high-trait and low-trait anxious subjects s creened respectively from young and elderly adults were presented with sentences that they either read or enacted.They were then asked to recall the object of e ach sentence and to identify its format of encoding.Results (1)There were significant age-related difference s in both item and source memory,while soruce memory wasn't found to be more sen sitive to aging than item memory;(2)Anxiety impaired the memory performance of o lder people,while had no adverse effect on that of younger adults,and even impro ved their conditioned source memory performance.Conclusions (1)Source memory wasn't selectively disrupted by aging.(2)Anxiety had adverse impact on the individual differences in episodi c memory aging,which suggested that intervention of anxiety may improve the olde r people's memory functioning.
