Comments on article by Scherer et al. (see record 2018-16097-001). In their study, Scherer et al. explore the aesthetic experience of opera spectators using a 12-item fuzzy emotion questionnaire. Hence, they make a contribution to the emerging endeavors to conduct empirical aesthetic studies in the field. Laboratory studies of aesthetic appreciation may, to some extent, be limited with respect to ecological validity. Investigating aesthetic appreciation in the context of its usual occurrence—and, by association, investigating aesthetic appreciation in a fully ecologically valid way—is a desideratum of today’s research. Attempting to classify (field) studies across domains of aesthetic appreciation spans up an at least three-dimensional (3D) space, constituted by factors such as settings, sensors, and tasks.
