This is indicative of the present environment that we are confronted by innumerable information and advertisements. After this deluge, the question is that how many and how much we remember them. Only a few advertisements remain in one`s memory. The capaity of momory is limited in human brain and most of advertisements disappear instantly from the mind of the consumer. The primary focus of this thesis is how the designer can be more sensitive and responsive to advertising effects in terms of the consumer`s interest. According to perceptual and behavior psychology, the consumer is inclined to perceive various advertisements in much more simplified image and conception. If anything complex should happen in the consumer`s mind, the filtering process of perception will make it much simpler than we think. Therefore, the design element simplication is an essential part of advertisements in order for the consumer to remember them easily and longer. When designing advertisements, the designer must consider selecting design elements for the better effect on the basis fo design simplification and consistent design concept. The object of this thesis is to give the designer a new perspective to gain a greater interest from the consumer regarding the characteristics of design element simplification.
