People differ in how they respond to artworks. Measuring such individual differences is helpful for explaining response variability and selecting particularly responsive subsamples. On the basis of a sampleof items indicating relevant behavior and experience, we exploratively constructed the AestheticResponsiveness Assessment (AReA), a screening tool for the assessment of individual differences inresponsiveness to art in English and German. Exploratory and confirmatory factor analyses suggestedthree first-order factors labeled aesthetic appreciation, intense aesthetic experience, and creative behavior,and a second-order factor aesthetic responsiveness. Aesthetic responsiveness was assessed in N = 781 participants from the United States and Germany, and measurement invariance analysis demonstratedfull metric and partial scalar invariance across language versions. AReA scale scores yielded goodreliability estimates. Validation studies confirmed expected associations between AReA scale scores andmeasures of related constructs, as well as continuously and retrospectively recorded responses to music,visual art, and poetry. In summary, the AReA is a promising, psychometrically evaluated instrument toassess aesthetic responsiveness built on a mixture of exploratory and confirmatory construction strategies.It
