metacognitive demands
元认知负荷（元认知需求）；指用户在与系统交互时为规划、监控与调节自身思维及信息评估策略所需要付出的认知负担。
English Definition
"The cognitive burden placed on a user to plan, monitor, and regulate their own thinking and information-evaluation strategies while interacting with a system."
用法说明 · 针对中文母语者
在 HCI/UX 研究中常用于分析系统对用户'隐式认知要求'，区别于更广义的 cognitive load。设计中可通过 scaffolding、contextualized prompt 等方式降低。
常见错误
- ·与 cognitive load 等同；cognitive load 是工作记忆负担的统称，元认知负荷聚焦于对自身认知过程的调控
- ·忽略 'demands' 在此处是'对用户提出的要求'，而非系统本身的负荷
