In psychology, rigidity, or mental rigidity, refers to an obstinate inability to yield or a refusal to appreciate another person's viewpoint or emotions and the tendency to perseverate, which is the inability to change habits and modify concepts and attitudes once developed.[1][2]
A specific example of rigidity is functional fixedness, which is a difficulty conceiving new uses for familiar objects.[3]
