This paper investigates the premise that products can be designed in a principled persuasive way to induce behavior change; specifically it explores how designers can adopt behavior change theories from psychology to design products that make people behave more environmentally responsible. Studies were conducted in two parts; Part I entails a retrospective study of persuasive products with behavior change intent. Adopting the Elaboration Likelihood Model of persuasion from Psychology, these products were studied with respect to the elaboration of the persuasive message. Part II presents 2 empirical studies of behavior change based on the ELM to test the effectiveness of these strategies in product design. The studies showed that the aesthetics of a product can influence how it is used and can prompt users to change their behavior. This work shows that if designers identify the right information-processing route, the visual appearance of a product can cue desirable behavioral responses. This is an example of an evidence-based approach to understand the link between perceived formal and meaningful properties of design and how these properties influence behavioral responses.
