Document Summary

Perception: the process by which out sensory receptors an nervous system receive and represent stimuli from our environment, the process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events. Fovea images flipped upside down at this point. Our brain flips this image for us and it uses perception to understand that. We can feel the floor with our feet, which can send signals to our brain that tells it that the floor is near our feet. Babies may see their vision inverted at birth. Seeing the image upside down is the sensation and the brain making sense of that is the perception. Similar to expectations because we have experiences with certain situations. Perceptual constancy perceiving objects as unchanging even as illumination and retinal image change. This is an active process that our brain is constantly engaged in. We don"t have to rediscover things every time one of these things appear: shape, size, color, brightness.
