 In aesthetics research, complexity has been divided into three dimensions that account for the interaction between the amount of elements, differences in elements, and patterns in their arrangement.Furthermore, this characteristic in aesthetics consists of a wide spectrum, ranging from low complexity to high complexity.Key studies have found through Galvanic skin response that more complex artworks produce greater physiological arousal and higher hedonic ratings, which is consistent with other findings that claim that aesthetic liking increases with complexity.
