Semiotics:

The importance of signs and signification has been recognized throughout much of the history of philosophy and in psychology as well.

The use of signs that are understood and viewed the same through people's cultures and experiences helps to evolve and understand symbols, signs and objects.

Artist's can also use semiotics to lure their audience into viewing the work, having a second look, try and work out and understand rather than a glance.

This advert of pasta. what is seen, what makes you feel comfortable and draws you in. would you buy the food ? yes. why ? because of the rich luscious colours.

The artist's have used factors that humans are familiar with, the red background has been used, as most people would see it as love and warmth. The pasta has been set in this string bag with other vegetables, which subliminally tells you that the pasta is fresh, tasteful and good for you.

The use of Semiotics can be very powerful if applied correctly.

'Semiotics has changed over time, since semioticians have sought the weaknesses in early semiotic approaches. Even with the most basic semiotic terms there are multiple definitions. Anyone attempting semiotic analysis would be wise to make clear which definitions are being applied and, if a particular semiotician's approach is being adopted, what its source is'
