在严格控制的实验中，年龄是如何影响大脑的，尽管这在很大程度上是人为设计的，我们已经知道了很多，但这些影响是否可以推论到日常生活中？自然主义的刺激，如电影，非常接近真实世界，并提供了一扇窗，让我们了解大脑对复杂的日常事件做出及时和有节制的反应的能力。年轻人对这些刺激的反应是高度同步的，但在自然主义观看过程中，年龄如何影响神经反应仍有待观察。为此，我们在看电影期间扫描了剑桥老龄化和神经科学中心(Cam-Can)基于人群的大样本(N=218)。被试之间的同步性随着年龄的增长而下降，因此老年人对这部电影的反应更具特殊性。这降低了与对注意力控制敏感的认知措施相关的同步性。我们的发现表明，神经反应性随着年龄的变化而变化，这可能对现实世界的事件理解和记忆具有重要意义。
Much is known about how age affects the brain during tightly controlled, though largely contrived, experiments, but do these effects extrapolate to everyday life? Naturalistic stimuli, such as movies, closely mimic the real world and provide a window onto the brain's ability to respond in a timely and measured fashion to complex, everyday events. Young adults respond to these stimuli in a highly synchronized fashion, but it remains to be seen how age affects neural responsiveness during naturalistic viewing. To this end, we scanned a large (N = 218), population-based sample from the Cambridge Centre for Ageing and Neuroscience (Cam-CAN) during movie-watching. Intersubject synchronization declined with age, such that older adults' response to the movie was more idiosyncratic. This decreased synchrony related to cognitive measures sensitive to attentional control. Our findings suggest that neural responsivity changes with age, which likely has important implications for real-world event comprehension and memory.
