 Intermittent Schedule of Reinforcement is anything that isn't an FR-1 or a CRF, Continuance Schedule of Reinforcement, which same kind of a yes. You're gonna re-enforce intermittently. Almost well in this phrase without being tied to a particular schedule, kind of willy-milly, which is really weird for the field because we try not to do that to be all technological and behavioral and see those concepts. Anyway, Intermittent Schedule of Reinforcement.
