- Support multitasking
Experiential cognition
Fast thinking - Perceiving and reacting to events around us - requires a certain level of expertise and engagement
Reflective cognition
Slow thinking - compare and contrast, making decisions

Leads to novel ideas and creativity
Attention

Salience
A quality of how information is displayed for setting things apart
Visual Variables Characteristics
Selective
Associative
Quantitative
Order
Selective
How easy a change in the variables makes the element being selected from the others
Associative
How easily elements w/ similar elements can be grouped across changes in other variables
Quantitative
Whether the difference between two elements can be interpreted numerically
Order
Whether the variable supports comparison between other elements
Visual salience is concerned with which visual characteristic
Selective - how easily an element “pops out”
Sensation
Refers to how information is acquired from environment via senses
Kinesthesia/Proprioception
The awareness of the position and movement of parts of the body
