本文回顾了电子激活记录仪（EAR）作为一种动态生态瞬时评估工具，用于观察日常行为。从技术上讲，EAR是一个录音机，当参与者在他们的生活中断断续续地记录环境声音片段。从概念上讲，这是一种自然的观察方法，可以产生一个人一天的声学日志。EAR的强大之处在于不引人注目地收集真实的现实观测数据。在原始记录的水平上保持高度的自然主义，它类似于民族志方法；通过抽样和编码，它可以进行更大规模的实证研究。本文概述了EAR方法，回顾了其有效性，实用性和局限性，并在动态评估的当前发展背景下讨论了它，特别是新兴的移动传感领域。
This article reviews the Electronically Activated Recorder or EAR as an ambulatory ecological momentary assessment tool for the real-world observation of daily behavior. Technically, the EAR is an audio recorder that intermittently records snippets of ambient sounds while participants go about their lives. Conceptually, it is a naturalistic observation method that yields an acoustic log of a person’s day as it unfolds. The power of the EAR lies in unobtrusively collecting authentic real-life observational data. In preserving a high degree of naturalism at the level of the raw recordings, it resembles ethnographic methods; through its sampling and coding, it enables larger empirical studies. The article provides an overview of the EAR method, reviews its validity, utility, and limitations, and discusses it in the context of current developments in ambulatory assessment, specifically the emerging field of mobile sensing.
