Emotion
How we feel
Design + The Brain · LEARN
Emotion is not the opposite of usability — it is part of it. Don Norman's Emotional Design argues that attractive things are perceived to work better, and his research with colleagues showed that aesthetics measurably affect perceived usability. Feeling shapes judgment before reason gets a vote.
Color, typography, imagery, tone of voice, and motion all carry emotional charge. A bank's interface and a festival poster communicate with the same perceptual machinery but aim at opposite feelings: trust and calm versus energy and release. Skilled designers choose that register deliberately and keep it consistent across every touchpoint.
Emotion also drives memory and behavior: people remember what they felt, and they return to what felt good. Delight is a design requirement, not a bonus.
