Perception
James Gibson (1904-1979) states that perception happens because of our human instincts. This means it can't be learned. He suggests that perception is needed for humans to stay alive. Neanderthals would have needed perception to escape danger, suggesting perception is the result of evolution. Gibson's theory is known as the "Ecological Theory" , because he says that perception can only be explained by our environment. To Gibson, Sensation = perception.
