A framework for organizing the semantic structure of aesthetic experience is proposed. The new framework is presented in an 'affect-space' and consists of three sets of dichotomous classifications: (1) internal locus (the felt experience) versus external locus (the description of the object), (2) 'affect-valence' -the attraction to (positive valence, e.g. preference, awe) or repulsion from (negative valence, e.g. hatred, disgust) the artwork/object -versus 'emotion-valence' -the character/contemplation of an emotion (happiness-an example of positive valence, sadness-an example of negative valence), and (3) deep versus shallow hedonic tone-e.g. 'awe' is deep, 'preference' is shallow. Deep hedonic tone is proposed as a better index of aesthetic experience (awe, being moved etc.) than shallow hedonic tone (preference, pleasure, enjoyment). Deep, internal locus, affect-valence during the contemplation of an object amenable to an aesthetic judgement (beautiful, ugly etc.) presents the necessary and sufficient conditions for an aesthetic experience. The framework allows future researchers to consider which aspects of an experience come closest to actual aesthetic experience from an empirical aesthetics perspective. It also highlights the limited value in grouping together so many aesthetic experiences under the rubric of emotion, such as aesthetic emotions, preference, basic emotions and so forth. Our framework paves the way for testing and further development of theory on aesthetic experience. Submitted 2016 February 10; accepted 2016 April 3. KEYWORDS: aesthetic experience, aesthetic emotions, affect, hedonic tone, locus THIS paper presents a semantic framework that organizes critical aspects of aesthetic experience for psychological and philosophical research. Recent years have seen a boom in attempts to draw together theories and empirical data on aesthetic experience (Jacobsen, 2006;Leder & Nadal, 2014) . Yet, as some accounts point out, there exist numerous gaps and confusions (e.g., Augustin, Wagemans, & Carbon, 2012;Konečni, 2012;Locher, Overbeeke, & Wensveen, 2010). One of the most critical is the definition of the aesthetic experience itself. An aesthetic experience may be defined through the philosophical concept of disinterested contemplation (Levinson, 1992). It may involve a combination of cognitive and emotional processes (Locher, et al., 2010). It may be defined in terms of the qualities of the object (music, artwork, etc.) or in terms of the affective sensations of the individual as a result of contemplating the object (Beardsley, 1969). The act of creative production (such as a musician playing at a concert, an artist painting in a studio, or a composer at work) and its relationship to the perception and contemplation of art works are involved (Tinio, 2013). The brain activity that corresponds to aesthetic experience is another way of defining the process, although the neuroscientific understanding of aesthetic experience is in its infancy (Brattico, Bogert, & Jacobsen, 2013;Brattico &...
