The paper describes an attempt to understand if and how product affordances and guessed performance alter the user ability to assess real performances during actual interaction with the product. The research work tries to experimentally find evidences of the existence of the “expectations about performance” guessed when the users see the product, if they correlate with product affordances and how the following interaction with the product modifies the users' opinion. The experiment has been performed by using four common flashlights as products and more than one hundred students as a users sample. The results of the performed test demonstrated that expectations about performance and affordances are concepts deeply intertwined.
