Designing for the Mind: The Psychological Principles Behind Effective UI/UX
summary
Clear, testable rules: apply Hick’s Law to keep choices minimal so users decide faster (Google’s pared homepage holds attention after almost two decades of the same layout); use the serial-position effect to put key CTAs at the start and end (Apple surfaces flagship product and final CTA); reduce cognitive load with chunked layouts and WCAG-compliant contrast; use the chameleon effect via avatars or microcopy to nudge emotion (Duolingo-style feedback). Avoid dark patterns: no bait-and-switch free trials, hidden fees at checkout, forced-continuity, disguised ads or confirm-shaming.
