Workshop introduction to Psychology for Designers at UX Brighton's one-day Psychology for Design workshop (9 May 2017). Joe Leech covers how people build mental models of the world and how that knowledge can create better user experiences; the day applies psychological principles of planning, decision making and perception to product and user interface design through hands-on sketching and exercises. Outcomes include designing to match how people think and behave, finding and applying psychology theory to digital product design, and advocating design decisions with psychological reasoning.
