Comparison of Parametric and Nonparametric Modeling: Aesthetic Effect of Kamran Khavarani?s Paintings

This research is an extension of Amirmostofian, Mozayeni (2016). Our hypothesis is that Khavarani?s painting style, Abstract Romanticism, combines artistic elements that impart positive effect on viewers? psyche. Our data encompass 320 surveys. Previously, we reported three nonparametric tests results, and concluded that Khavarani?s paintings have positive effects on viewers? psyche. In this research we examine new results for six Multivariate General Linear Model (MGLM) estimations for six Khavarani?s groups. With their R2, 0.04-021, and negligible and insignificant coefficients for variables Age, Gender, and the base mood, we propose that Khavarani?s paintings influence the subjects? Mood After, the dependent variable in our model. We invoke Vartanian and Skov (2014), and recognize that subjects in the six groups experienced a meditative joy.
