Document Summary
Different colours and levels of brightness two dimensional representation. Our perception goes far beyond the information given. Our visual system is not like a camera. We sample select parts of the visual world and we build up our own interpretation. We see the world in terms of objects. A lot of processing needs to be done, Necker cube: edges, corners, we see a cube that has by-stable perception. A pattern is a complex configuration of sensory signals: Sequences of sounds: recognized as words, music, associated with semantics, emotion. We are easily and quickly able to recognise an object even though it is in an orientation we have never seen before. We are usually not even aware of the basic sensory signal, but only of the meaning there is a lot going on to produce this feed-forward information flow. Attention and what you are expecting can feedback and change the neural response at lower levels.
