Formed from 'constant' + '-cy', but the psychological sense is a domain-specific extension of the general idea of being unchanging.

Etymology

Constancy comes from Latin parts con- 'together' and stare 'to stand', the same idea in constant and like the English word stand. So in perception, constancy is the mind 'standing' on the idea that an object stays the same even when light, distance, or angle changes.
