People tend to prefer objects with curved contours to objects with sharp contours (e.g. Bar & Neta, 2006; Palumbo & Bertamini, 2016; Palumbo, Ruta, & Bertamini, 2015). Nevertheless, as with other aesthetic features (Jacobsen, 2004), there are also considerable differences among people in the extent to which they prefer curvature. The aim of the research presented here was to explore the possible reasons for such differences. Specifically, we sought to determine whether individual differences in preference for curvature were explained by participants’ aesthetic sensitivity, experience with art, openness to experience, or intelligence. Thus, we asked 40 participants to perform a 2AFC preference for curvature task (Munar, Gómez-Puerto, Call, & Nadal, 2015), a computerized version of the Visual Aesthetic Sensitivity Test (Götz, Borisy, Lynn, & Eysenck, 1979), a short art interest and activities questionnaire (Brieber, Leder, & Nadal, 2015; Brieber, Nadal, Leder, & Rosenberg, 2014), the openness to experience scale from the NEO-PI-R (Costa & McCrae, 1992), and Raven’s intelligence test. Linear mixed effects modelling was used to predict participants’ preference for curvature (proportion of curved choices) using their aesthetic sensitivity, experience with art, openness to experience, and intelligence scores as predictors. Results are discussed in terms of the multiplicity of cognitive and affective processes contributing to aesthetic appreciation (Leder, Belke, Oeberst, & Augustin, 2004; Leder & Nadal, 2014).
