Observational studies of human responses frequently yield only tenuous or no support for hypothesized relationships. These null findings often may be due to reliance on single observations rather than on multiple measures aggregated over contexts or occasions. This article discusses the principle of aggregation and describes the development and evaluation of aggregated measures in a study of the relationship of nursery nurse's behavior to emerging newborn temperament.
对人类反应的观察性研究常常只能为假设的关系提供微弱的支持或根本没有支持。这些无显著结果往往可能是由于依赖单一观察，而非依赖在不同情境或场合下汇总的多种测量方法。本文讨论了汇总原则，并描述了在一项关于托儿所护士行为与新生儿气质形成关系的研究中汇总测量方法的开发与评估。
