The movement
What actually changed, against normal variation.
The part
What it is
A move within the normal band is not a finding, and treating it as one produces a great deal of activity in response to noise.
Sustained movement across two or more waves is the threshold worth acting on for most perception measures.
The smallest level
The attributes it carries
Each attribute is one of the framework’s shared types. What a date is, and how it is written, is defined once for the whole model — the note here says what it means in this particular place.
