*2.1.2. Representative realism*

Representative realism is the indirect perception of any matter. It is the deeper impression that depends on a thoughtful approach to the surroundings. Unconsciously, we perceive components linked to the person's culture and education. Each element of the surroundings has a direct message, but through the perception of it, it translates to the deeper philosophic sensitivity of it. The interiors that include samples of each users' cultures will be well perceived and the users will react positively to it.

#### *2.1.3. Idealism*

Idealism depends on everything, from the spirit and the mind to the reality and the human experience. The end user has values and beliefs. By linking them to the environment, it will reflect ethics, standards and faiths. Perception only relies on those criteria; therefore, if any of these are absent, a lack of perception reality will occur. Spirit and cognitivism are the two basic forms of idealism perception. Cultures, education, ethics and beliefs are the keys for the productivities of such a way of perception. Interiors should include some aspects from each personality, cognition and value set to become a beautiful interior.

#### *2.1.4. Phenomenalism*

Perception of things does not change whether people perceive them or not. Unlike idealism, everything exists in our surrounds as phenomena created by a human or by nature. It depends on each behavior to perceive it, so it becomes a reaction. In such way of perception, people will react only if the surroundings attract them.

#### **2.2. Perception of the interiors**

People perceive their environment based on their background culture, education, emotions and cognitional and emotional phenomena. When the person in a space "processes" the available information, he/she perceives consciously, and so they use their relative cognition. Cognitive responses reflect what life has taught us (relevant, interesting, useful and desirable). All data added throughout time in the form of direct education or indirect culture backgrounds is cognition. While the person in the space "processes" the available information, he/ she perceives unconsciously (automatically, involuntary). They use their comparative emotions. Emotional responses reflect our dominant sense (based on culture and personality). Emotions are the natural feelings based on data perception [7].

The link between people and their places is clarified through the explanation of environmental psychology. When a person enters an interior, he starts perceiving its surroundings. Two main responses occur: cognitive and emotional. This is the so-called behavioral response. The person starts to link his surrounding elements to all his background data (cognitive responses), then he links them to his feelings (emotional responses) and reacts based on all of these steps. The reason for these reactions at the beginning is clear for him (conscious), and then he keeps behaving while forgetting the original reasons (unconsciously). These responses serve to prove the success of the interior (**Figure 1**).

People select and positively react to surroundings that enforce and strengthen their productivity. Productivity happens when humans feel safe and secure and when their surroundings reflect beauty. The interior designer has a prescribed responsibility to create an environment that helps individual personalities, genders and cultural and ethnical groups in their daily life.

As a user, how might one react to an interior? Environmental psychologists and designers suggest three possible answers that are abundant: through visual perception, the scent and the sound of the place. In fact, the senses that affect interior perception are vision, touch, smell and sound [8].
