Frontier Radar Source screening Cross-domain dossier 8 candidate sources Added 2026-09-12

Why this question · 为什么值得追踪

When effort starts to feel expensive.

This dossier will examine the shift from a simple willpower-depletion story toward effort valuation, recovery quality, and the design of demanding work. It will separate acute cognitive fatigue from longer-lasting recovery and health questions.

这个专题将从“意志力耗尽”的简单叙事，转向努力成本估值、恢复质量与高强度工作设计，并区分短期认知疲劳和更长期的恢复及健康问题。

Planned evidence map

Four lenses before one conclusion.

The dossier will keep mechanism, behaviour, recovery, and work design separate long enough to see where the evidence agrees—and where it does not.

01Source screening

Mechanism

机制

Cognitive control, neuro-metabolic hypotheses, and what has or has not replicated.

认知控制、神经代谢假说，以及哪些发现已经或尚未得到重复验证。

02Source screening

Effort & choice

努力与选择

How fatigue changes the perceived value of effort, reward, and initiating even pleasant activities.

疲劳如何改变努力、奖励和启动愉快活动的主观价值。

03Source screening

Recovery quality

恢复质量

Micro-breaks, sleep, movement, detachment, and the difference between feeling better and performing better.

微休息、睡眠、活动与心理脱离，以及“感觉好些”和“表现恢复”的区别。

04Source screening

Work design

工作设计

Workload, autonomy, flexibility, and when the system—not individual resilience—is the intervention target.

工作负荷、自主性与灵活性，以及何时干预对象应是工作系统而非个人抗压能力。

Research questions · 待研究问题

What the evidence desk will test.

These questions define the work ahead. They are not answers written in advance.

  1. 01
    Does the shutdown feeling reflect reduced ability, a higher subjective cost of effort, or both?“关机感”主要来自能力下降、主观努力成本升高，还是两者共同作用？
  2. 02
    Is there a repeatable load–fatigue relationship in demanding knowledge work without assuming one universal time limit?高强度知识工作是否存在可重复的负荷—疲劳关系，而不是人人相同的时间上限？
  3. 03
    Which forms of rest support recovery, and which merely replace work with another stream of stimulation?哪些休息方式真正支持恢复，哪些只是把工作替换成另一股刺激流？
  4. 04
    When do micro-breaks improve subjective fatigue, and when do they also restore cognitive performance?微休息何时只改善疲劳感，何时也能恢复认知表现？
  5. 05
    How should acute cognitive fatigue be distinguished from persistent burnout, sleep problems, loss of interest, or other health causes?如何区分短期认知疲劳、持续职业耗竭、睡眠问题、兴趣减退及其他健康原因？
Starting source queue

Traceability begins before publication.

These titles are the initial screening queue. A source becomes claim-bearing only after its design, sample, outcome, limits, and fit with the question have been reviewed.

From a frontier question to observable context.

从前沿问题，走向可观察的日常语境。

Translate the evidence into observable work–rest rhythms, choice friction, true psychological detachment, and recovery context—without turning recovery into another productivity contest.

把证据转化为可观察的工作—休息节律、选择阻力、真正的心理脱离与恢复语境，而不是把恢复变成另一场效率竞赛。
