代理感（SoAg）是对自己行为及其影响的控制感。它可以通过内部信号和外部线索增强或减弱。研究表明，老年人的SoAg水平有所下降，但这种变化背后的原因尚不清楚。我们调查了可能支持SoAg年龄相关变化的代理处理差异。使用一个改进版本的替代代理范式，我们通过操纵外部情境代理线索，在年轻人和老年人中测试了SoAg的调节。我们的研究结果表明，替代代理的错觉在老年人中不那么明显。这些结果在第二个实验中得到了重复，该实验还表明，老年人在内感受和本体感受任务中的表现明显更好。我们认为，对内部线索的依赖增加可能解释了老年人在代理处理方面的差异。
Sense of agency (SoAg) is the feeling of control over one's actions and their effects. It can be augmented or attenuated by internal signals and by external cues. Research has shown a reduction in the SoAg in older adulthood, but the reasons behind this change remain unclear. We investigated agency processing differences that may underpin age-related changes in SoAg. Using a modified version of a vicarious agency paradigm, we tested the modulation of SoAg by manipulating external situational agency cues in younger and older adults. Our results show that the illusion of vicarious agency was less pronounced in older adults. These results were replicated in a second experiment which also showed that older adults performed significantly better in interoception and proprioception tasks. We suggest that increased reliance on internal cues may explain differences in agency processing in older adulthood.
