Thin slices are used across a wide array of research domains to observe, measure, and predict human behavior. This article reviews the thin-slice method as a measurement technique and summarizes current comparative thin-slice research regarding the reliability and validity of thin slices to represent behavior or social constructs. We outline decision factors in using thin-slice behavioral coding and detail three avenues of thin-slice comparative research: (1) assessing whether thin slices can adequately approximate the total of the recorded behavior or be interchangeable with each other (representativeness); (2) assessing how well thin slices can predict variables that are different from the behavior measured in the slice (predictive validity), and (3) assessing how interpersonal judgment accuracy can depend on the length of the slice (accuracy-length validity). The aim of the review is to provide information researchers may use when designing and evaluating thin-slice behavioral measurement.
薄片法在广泛的研究领域中被用于观察、测量和预测人类行为。本文回顾了薄片法作为一种测量技术，并总结了当前关于薄片在代表行为或社会结构的可靠性和有效性方面的比较薄片研究。我们概述了使用薄片行为编码的决策因素，并详细介绍了薄片比较研究的三个途径：（1）评估薄片是否能够充分近似记录行为的总体或相互可互换（代表性）；（2）评估薄片在预测与薄片中测量行为不同的变量方面的效果如何（预测效度）；以及（3）评估人际判断准确性如何取决于薄片的长度（准确性-长度效度）。本综述的目的是为研究人员在设计和评估薄片行为测量时提供可用信息。
