Explain pre-attentive attributes and give three examples
This tests whether you know preattentive attributes are decoded in <200ms to guide attention freely. Name three such as color hue, size, and motion; then encode one variable in a dense scatter plot so targets pop out. Never call this decoration or color all.
This tests your understanding of preattentive visual processing and how to direct attention without cognitive load. A strong answer defines pre-attentive attributes as features decoded in roughly 150 to 200 milliseconds before conscious attention; gives three distinct examples such as color hue, size, and orientation; and explains binding one attribute to a specific data variable in a dense scatter plot so the target subset pops out while everything else recedes to a muted baseline.
