Pre-Attentive Attributes

Definition

Pre-Attentive-Attributes are used in data visualization to focus the readers view quickly on the most important point of information. It is achieved by modifying the appearance of that point of information, so that it sticks out in some way from the rest of the data. The effect is that the brain will catch the difference subconsciously and give that point direct attention.

Main categories of Pre-Attentive Attributes

There are four main categories of Pre-Attentive Attributes that determine the kind of difference of the attribute. These categories are Color, Form, Spacial position and Movement.
