Psychology & Design
summary
A practical model of perception, cognition, motivation, emotion, and behaviour appears with concrete methods: form conjectures, run experiments, quantify variables, iterate. Examples include adapting Fitts/Myers law for touch drag‑and‑drop, turning the heuristic probability = value ÷ work × confidence into testable measurements and using lab gear to measure touch force for friction and accuracy. A quick audit of the Tim Hortons app finds mismatched QR/barcode affordances, gray pins that obscure open/closed state, scattered rewards and GPS flows that create real user friction.
