Absolute Threshold
Captions available
The idea
The absolute threshold is the minimum stimulus intensity a person detects half of the time.
In practice
A candle flame at a great distance on a clear dark night sits near the visual absolute threshold.
Where people slip
The threshold is defined at half detection because there is no intensity detected every time and none never.
