A compact reference that maps psychology research — Fitts's Law, Hick's Law, the Peak-End Rule, Miller's Law — directly to interface decisions. Useful as a vocabulary for justifying design choices in reviews and as a checklist when diagnosing why an interaction feels slow or overwhelming.
Chosen by shared topics, the entries that hold them, and the people who recommended both.
Organized as short research-backed chapters on how people see, remember, decide, and feel, this is the most accessible bridge between cognitive science and design practice. The sections on peripheral vision, progressive disclosure, and intrinsic motivation are particularly applicable to interface work.

Where most design books stay in the abstract, this one opens with specific visual decisions: spacing scales, type hierarchies, color palette construction, shadow systems. Written by developers who taught themselves visual design, it's unusually practical and works equally well for product designers who want stronger visual intuition.
