Basic Principles of Pupillometry
observation I:Brightness has the biggest influence on pupil size.
observation II:Every change in pupil size occurs independently
from other changes. (linear combination of changes)
observation III:Pupil size increases proportionally to the difficulty level
of the task to be solved.
