Morphology
The adjective 'perceptual' (relating to perception) combined with the noun 'constancy' (stability, unchangingness) yields a directly compositional meaning: stability in perception despite changing sensory input. This follows a straightforward adjective+noun pattern and is derivable by a B1 learner who knows both constituents, so the term is transparent despite its technical use in psychology.
Etymology
Perceptual constancy comes from the idea that perceptual means 'what you notice' and constancy means 'staying the same'. Imagine seeing a friend from far away or in dim light and still knowing it is the same person, so perceptual constancy is when our senses keep things looking the same even if light, distance, or angle change.
