The STSS measures situation-specific thinking style in consumer decision contexts — the degree to which, in a specific situation, a consumer relies on experiential/intuitive versus rational/systematic processing. Novak and Hoffman (2009) built on Epstein's (1994) cognitive-experiential self-theory (CEST) and the REI (Pacini & Epstein, 1999), but departed from trait-level measurement by developing situation-specific items. This enables researchers to examine thinking style fit — the alignment between the naturally activated thinking style and the processing demands of a task or message. Situation-thinking-style fit enhances processing fluency, attitude confidence, and behavioural intention. Used in research on online consumer decision making, flow, and persuasion via message type fit.
