A measure of the ease of understanding text.
The principle of both sides of an object having a sense of symmetry. It ensures that the weight and visual mass are distributed evenly on both sides of a surface.

A graphical representation of a scenario, usually created and presented in sequence.
A well-known cognitive psychologist's principle that says that the time it takes to make a decision varies logarithmically according to the number of choices. As more options are presented, more decision time is required due to the mental work of comparing and contrasting each potential option.
A sequence of user actions on a website. In UX design, it's important to note the order in which users interact with your site so you can redesign it for optimum usability.
