Behaviorism
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State

Show
Watson claimed he could shape any healthy infant into any profession by controlling that infant's environment alone.
Watch for
Setting mental processes aside was a methodological rule, not a claim that thought does not exist.
