The landscape of human memory and event cognition research has witnessed a transformative journey toward the use of naturalistic contexts and tasks. In this review, we track this progression from abrupt, artificial stimuli used in extensively controlled laboratory experiments to more naturalistic tasks and stimuli that present a more faithful representation of the real world. We argue that in order to improve ecological validity, naturalistic study designs must consider the complexity of the cognitive phenomenon being studied. Then, we review the current state of "naturalistic" event segmentation studies and critically assess frequently employed movie stimuli. We evaluate recently developed tools like lifelogging and other extended reality technologies to help address the challenges we identified with existing naturalistic approaches. We conclude by offering some guidelines that can be used to design ecologically valid cognitive neuroscience studies of memory and event cognition.
人类记忆和事件认知研究的领域见证了从使用在广泛控制的实验室实验中的突然、人为刺激向更自然的任务和刺激的转变，这些刺激更真实地反映了现实世界。我们认为，为了提高生态有效性，自然主义的研究设计必须考虑到所研究的认知现象的复杂性。然后，我们回顾了当前的“自然主义”事件分割研究的状态，并批判性地评估了经常使用的电影刺激。我们评估了最近开发的工具，如生活记录和其他扩展现实技术，以帮助解决我们在现有自然主义方法中发现的挑战。最后，我们提供了一些可以用来设计记忆和事件认知的生态有效认知神经科学研究的指导方针。
