Towards a unified model of aesthetic pleasure in design

In this study we test the Unified Model of Aesthetics (Hekkert, 2014), which posits that the aesthetic sense has evolved to identify and value prospects for safety and accomplishment. The principles of unity in-variety, most-advanced-yet-acceptable and autonomous-yet-connected are considered manifestations of these conflicting urges at separate levels of stimulus processing. We empirically integrate these principles to gauge their unique contribution to the aesthetic experience, using two distinct surveys (study 1-300 respondents and 20 stimuli, study 2-60 respondents and 24 stimuli). Both surveys confirm the three principles constituting the Unified Model of Aesthetics. The principles are found to operate independently and jointly, although unity-in-variety has the strongest impact on aesthetic pleasure. (C) 2017 Elsevier Ltd. All rights reserved.
