Having already pinpointed the fact that schemas are personalized according to the person, Tracey (2006, p.51) claims that Schema Theory suggests that when a person's schema on a particular topic is detailed, it would be easier for them to accept and absorb the introduction of new information on that topic. Whereas, it is suggested that when one does not have an existing schema on a particular topic, that person would have difficulty with absorbing the information transmitted to them because they cannot identify with what is being conveyed to them. To sum it up, the Schema Theory is basically a mental framework a person has on a particular topic and that a person's schema can affect the way they receive new information about a certain topic.

Therefore, with the Schema Theory having been introduced in the previous paragraphs, the question as to why schema is important when creating an image is raised. Why is it important? In the case of advertisers, it is fairly straight forward – to make sure the images they use appeals to and is understood by their target audience. In order to make sure this happens, they would need to use images which their audience identifies with. These same reasons can also be applied with just images in general. Schema plays a role in the process of image construction so the person making the image can use widely acknowledged concepts or ideas which people can relate to in order to create a picture.

For instance;

The video above is similar to "Chinese whispers". However, instead of a sentence being verbally relayed from one person to the next, it is a drawing.

The second contestant was able to identify the picture drawn by the first contestant because elements that a kangaroo possesses, that is within their schema, was identified in the picture - such as the shape of a kangaroo and the pouch with the baby kangaroo in it. However, as the pictures get passed along, the identifiable element gets distorted or eliminated and thus becomes unrecognizable and not within their schema of a kangaroo (or anything they have ever seen). Therefore, this video shows that people recognize things by drawing on their previously-stored knowledge of an object, or in the case above, animal. When faced with things not within their schema, they would link the foreign object to the closest thing they can relate it to, in the case above, a painting of Mona Lisa.

If you have never watched Pokemon, you would most likely not be able to identify with the object in the picture above. Instead, you would most likely try to draw on the closest thing in your schema to identify the object. Therefore, you are most likely to identify the above image as a pink blob or a pink paint splatter with a smiley face. However, if you are familiar with Pokemon, you would know that it is a Pokemon called Ditto.

In conclusion, schema is essential when creating an image because the illustrator would need to have knowledge about the object they are illustrating to make the image understandable and successfully. Basically, without schema, the illustrator would not be able to create an image because it would mean they do not have a basic framework of how the object they are illustrating is supposed to look like.
