3 Do you see what I see?

This section provides you with the chance to investigate the visual system and visual perception exploring both the biology of the visual system and theories that have been put forward to explain how people perceive the visual world. The materials presented here question how our perception of the world can be altered due to shortcuts taken by our brain, which in turn alters our experience of the visual world. Research on the human visual system has demonstrated how our eyes and brain need to work together to make sense of the world and other senses also need to work together with our visual system in order to interpret our surroundings accurately.
