What is perception you may ask? Perception is the process by which the five senses are chosen, organised and interpreted (Solomon, M R et al, 2010).
If a products packaging is untidy the brain automatically tells you that your not going to like it. It is only when you are approached to test the product that you could surprise yourself and like the product - so don't always trust your initial perception of the product.
There are many other ways of using your perception apart from the sense of smell. The human body has many ways of perceiving thing. There is the sense of touch, hearing, seeing, taste and of course smell. All these different sense do different things but many interrelate. Without these senses we would not be able to differentiate things, especially taste, as everything would taste the same! How boring would that be??
The Gestalt principal says that people can only get a true idea of the item by seeing the full picture and not just bits of information. The word Gestalt means whole, pattern or configuration in German. The system implies that consumers tend to perceive an incomplete picture as complete as they are filling in the blanks with their own personal experience. This is why a person can read a sign even if some letters are missing as they can fill in the blanks with their own personal experience. (Solomon et al, 2010)
