目的：制定优化老年人功能表现的策略需要了解老年人在现实世界中执行任务的行为，并在研究方案中捕获这些相互作用。这是一个重大的挑战，因为在捕捉真实的世界中运行的上下文变量和约束与在受控实验环境中可以实际进行的研究规模之间存在某种程度的紧张关系。本文提出了一种研究方法，可以用来帮助确保研究协议的生态有效性。其目的是展示如何生态有效的方法提供更深入的了解老年人在真实的世界settings.Methods的表现：该方法涉及的技术，如任务分析和模拟。从两个研究项目的例子检查老化和现实世界中的基于计算机的工作任务的性能被用来证明这种approach.Results：本文演示了如何生态有效的研究方法产生的信息，人类的表现，可以转化为现实世界的问题的解决方案。
Purpose:Development of strategies to optimize the functional performance of older adults requires understanding the behavior of older people doing tasks in real-world settings and capturing these interactions in research protocols. This is a major challenge as there is some degree of tension between capturing the contextual variables and constraints that operate in the real world and the scale of research that can be realistically conducted within controlled experimental settings. This article presents a research approach that can be used to help ensure the ecological validity of research protocols. The intent is to demonstrate how an ecologically valid approach affords greater insight into the performance of older adults in real world settings.Methods:The approach involves techniques such as task analysis and simulation. Examples from two research projects examining aging and the performance of real-world computer-based work tasks are used to demonstrate the application of this approach.Results:The article demonstrates how an ecologically valid research approach yields information about human performance that can be translated into solutions for real-world problems.Implications:Ecologically valid research protocols offer the potential for providing answers to real-world problems and advancing theory regarding aging and functional performance.
