Instrumentality,aesthetics and symbolism of physical artifacts as triggers of emotion

Building on qualitative data collected from three groups of professionals who assessed the green colour of a public transportation bus, this paper develops a model of the relationship between physical artifacts and emotions. The model suggests that artifacts need to be analysed according to three conceptually distinct aspects: instrumentality, aesthetics and symbolism. These three aspects are suggested to arouse emotion through different mechanisms: a hygiene, a sensory and an associative mechanism. The model opens an arena for extensive future research on the role and influence of physical artifacts in general and on emotions in particular.
