As a concrete concept of various objects in daily life, the characteristics of shape (angular
and rounded corners) appear in every corner of individual life. With the evolution and development of
culture, shapes of things or patterns have developed unique meanings to individuals, and have impacts on
individual behavioral decisions. Based on previous studies, we summarize the metaphorical connotation
of shape and the neurophysiological basis of shape metaphor from the perspective of metaphor theory
and embodied theory, and discuss how the connection between shape and its metaphorical meanings
affects individual moral judgment, consumption behavior and prosocial behavior, and discuss the future
research orientation of shape metaphor.
