The production of pantomime is a sensible task to detect praxis deficits. It is usually assessed by presenting objects visually or by verbal command. Verbal instructions are given either by providing the name of the object (e.g., "Show me how to use a pen") or by requiring the object function (e.g., "Show me how to write"). These modes of testing are used interchangeably. The aim of this study is to investigate whether the different instructions generate different performances. Fifty-one healthy participants (17-89 years old) were assessed on three pantomime production tasks differing for the instruction given: two with verbal instructions (Pantomime by Name and Pantomime by Function) and one with the object visually presented (Pantomime by Object). Results showed that Pantomime by Function produced the poorest performance and the highest frequency of Body Parts as Tool (BPT) errors, suggesting that the way the instructions are given may determine the performance in a task. Nuances in test instructions could result in misleading outcome.

测试指令的效果：哑剧制作任务的示例。

哑剧的产生是检测实践缺陷的明智任务。通常通过视觉呈现或通过口头命令来评估对象。通过提供对象的名称（例如，“显示如何使用笔”）或要求使用对象功能（例如，“显示如何书写”）来给出口头说明。这些测试模式可以互换使用。这项研究的目的是调查不同的指令是否产生不同的性能。对51名健康参与者（17-89岁）进行了三种哑剧制作任务的评估，这些任务与给定的指令有所不同：两种带有口头指令（按名称命名的手势和按功能表示的哑剧），以及一种带有视觉呈现的对象（按对象表示的手势）。 。结果表明，“按功能进行手势”产生的性能最差，而“身体部位作为工具”（BPT）错误的发生频率最高，这表明给出指令的方式可能会决定任务的性能。测试说明中的细微差别可能会导致误导性结果。
