| Restricting her palette to reticent blacks, whites and grays, she conveys the spirit, changes and constancies of a pure, unsullied wilderness. |
| Different hardnesses and chemical constancies. |
| Sensible experiences group themselves round these constancies. |
| To the extent that they prevail, the constancies lend the perceiver's experience and behaviour relative stability. |
| There are, for example, reliable data that perceptual constancies are enhanced with the person's increasing age, improvement leveling off at about age ten. |
| Normal constancies also can be intentionally overcome, as in paintings of flabby watches and distorted people that apparently depict the unique perceptual world of the artist. |
