Cognitive Process Differences Between Moral Beauty Judgments and Moral Goodness Judgments

Abstract

Goodness and beauty have always been important topics of debate in the field of philosophy and aesthetics. The present study used behavior and event-related potentials (ERPs) to investigate whether moral beauty judgments and moral goodness judgments involve different cognitive processes or the same cognitive process under different language labels for the same human act. Behavioral results showed that individuals gave significantly higher scores for a beautiful face than an ugly face when making moral beauty judgments, but there were no significant differences between the two conditions when making moral goodness judgments. The ERP experiment displayed larger P2 amplitudes and the late positive potential (LPP) amplitude was elicited when displaying beautiful faces but not ugly faces during moral beauty judgments. However, during moral goodness judgments, the P2 and LPP showed no significant differences under the two conditions. In general, we conclude that moral beauty judgments and moral goodness judgments involve different cognitive processes, although they objectively refer to the same human act. One of the most important differences between moral beauty judgments and moral goodness judgments was that the former process involved an image, whereas the latter did not. The present conclusion provides important insights into the research in aesthetic perception and moral sense.
