The most informative signal is the direction of the gap between what a person expected and what they perceived receiving. When perceived performance exceeds the prior benchmark, the evaluation can move toward satisfaction; when it falls short, dissatisfaction becomes more likely. This comparison explains why identical outcomes may produce different judgments for people who began with different expectations.
Expectations function as the reference point against which perceived performance is judged, rather than serving as a simple background belief. A positive match or improvement supports a favorable evaluation, while a negative discrepancy can shift the judgment toward dissatisfaction. In behavioral research, identifying this reference point helps explain variation in responses to the same product, service, or outcome.
Emotional reactions provide a link between an evaluation and a later behavioral response. A favorable experience may be associated with continued use, loyalty, or recommendations, whereas dissatisfaction may be associated with switching. Including this emotional dimension allows a Satisfaction Model to address more than a rating alone and to connect perceived outcomes with observable or reported behavior.
Researchers can organize survey measures around prior expectations, perceived performance, overall satisfaction, and intended responses. This structure separates the experience itself from the respondent’s evaluation of it, making it easier to examine whether satisfaction follows a positive or negative discrepancy. The same survey can then assess outcomes such as continued use, loyalty, recommendations, or switching.
Feedback is most informative when researchers consider both what respondents expected and how they perceived performance. A favorable comment may reflect performance that exceeded expectations, while a negative judgment may indicate that the experience fell short. Relating these perceptions to the overall satisfaction judgment helps clarify whether feedback points to satisfaction, dissatisfaction, or a likely behavioral response.
The framework applies across consumer research, healthcare, education, and service settings because each can involve expectations, perceived performance, and subsequent behavioral responses. Its value is not limited to a single type of experience: researchers can use it to interpret user feedback, examine satisfaction-related judgments, and assess outcomes such as continued use, recommendations, loyalty, or switching within the setting studied.
