NLP looks at the ways we experience the world through our sensory organs. These representational systems are called VAKOG. VAKOG stands for:
V visual seeing
A auditory hearing
K kinesthetic feeling
O olfactory smelling
G gustatory tasting
According to the NLP model, people use those five sensory channels with varying emphases. We each have a preferred way of representing the world to ourselves, a preferred representational system. E.g. some people are very visually oriented; information over the other channels have less impact.
