Primary use / Purpose:
The preposition is that the fit between an action's strategic orientation and the actor's regulatory state can influence the amount of enjoyment the action provides. Regulatory fit can be manipulated both incidentally and integrally. Incidental regulatory fit involves activating fit separately from the context of the task of interest. Integral regulatory fit involves activating fit within the context of the task of interest; there are many ways to induce integral fit (see for example Cesario, Higgins, & Scholer, 2007). Regulatory fit, whether manipulated incidentally or integrally, can arise from a match between any goal orientation and its preferred means of goal pursuit. The Regulatory Fit Induction (RFI Instrument) is a measure of this construct.
