- 1988, Donald A. Norman, “The Psychopathology of Everyday Things”, in The Design of Everyday Things, New York: Basic Books:
- Affordances provide strong clues to the operations of things. Plates are for pushing. Knobs are for turning. Slots are for inserting things into. Balls are for throwing or bouncing. When affordances are taken advantage of, the user knows what to do by just looking: no pictures, label, or instruction is required.
