Summary
A university professor studying sleep disorders sometimes taught after staying up all night in the lab. She found these lectures difficult, feeling tired, humorless, and unable to concentrate or find the right words. After several weeks, she asked her students to guess which lectures followed sleepless nights, but very few could guess correctly.
Strongly Supported Conclusions
The effects of occasional sleep deprivation may feel stronger than how they actually appear in behavior.
Internal feelings of tiredness, humorlessness, and inability to find the right words may not always translate into noticeable performance issues.
In some situations, fatigue may be less noticeable to others than it is to the fatigued person.
