## Definition
认知负荷降低Cognitive Load Reduction指通过界面设计、任务拆分和流程优化减少用户完成任务所需的心理努力防止决策疲劳和任务瘫痪。
## Mechanism
1. **任务拆分**:将大型工作流分解为微小、可完成的微任务单元
2. **单一焦点**:每次仅推送一个最高优先级的可操作项,而非批量列表
3. **渐进披露**:按需逐步展示信息,避免信息过载
4. **即时上下文**:为每个任务提供充分的执行背景,减少搜索和回忆成本
## Applications
- 微冲刺Micro-Sprint5-15 分钟短时任务块
- [[Pomodoro Technique]] 时间盒工作
- 队列视图仅显示当前最关键项
- ADHD 用户友好设计模式
