Naturalistic Observation
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Naturalistic observation records behavior in its ordinary setting without the researcher intervening.
Show
A researcher counts hand-washing in a public restroom from a position where no one has been told a study is running.
Watch for
Being watched changes behavior. Concealment protects the data and creates the ethical question the design must answer.
