Read the following extract [http://peace.saumag.edu/faculty/kardas/courses/GPWeiten/C4SandP/VisualConst.html]
and the answer the following question:
Give one example of how perception is altered by our experiences.
Visual Constancies
The visual constancies are some of the most powerful examples of the difference between perception and sensation. Once again, what we know or what we think we know will overcome or modify our sensory experience. Size constancy occurs because we know the sizes that characterize familiar objects. Cars are bigger than people, buildings are bigger than cars, for example. So when we see a car and it is far away, the image of that car takes up less space on our retinas. As the car comes closer, its image takes up more space on our retinas, and we say it is getting closer. As noted earlier, when we view new or unfamiliar objects, we may have some trouble perceiving their distance from us...
...So the constancies provide firm evidence that perception and sensation are not the same. Perception is more than the simple reporting of sensations. Perception is profoundly altered by our experience.
