The present study examines source memory for actions (e.g., placing items in a suitcase). For both young and older adult participants, source memory for actions performed by the self was better than memory for actions performed by either a known (close) or unknown other. In addition, neither young nor older adults were more likely to confuse self with close others than with unknown others. Results suggest an advantage in source memory for actions performed by the self compared to others, possibly associated with sensorimotor cues that are relatively preserved in aging.
本研究考察了对动作的源记忆(例如,将物品放入手提箱中)。对于年轻和老年参与者,对自己执行的动作的源记忆比对已知(亲密)或未知他人执行的动作的记忆要好。此外,无论是年轻人还是老年人,都不太可能将自己与亲密他人混淆,而不是与未知他人混淆。结果表明,与他人相比,对自己执行的动作的源记忆存在优势,这可能与相对保留在衰老过程中的感觉运动线索有关。
