The Spacing Effect
A cognitive phenomenon where spacing systematically influences perception or decision-making.
Spacing Effect is a cognitive phenomenon identified in behavioral science that shapes how users perceive, remember, and decide. In product design, Spacing Effect explains why users behave in ways that seem irrational from a purely functional perspective. Products that understand Spacing Effect can design experiences that work with human psychology rather than against it. Products that ignore Spacing Effect create friction, confusion, and abandonment. Spacing Effect is one of many cognitive effects that form the behavioral substrate of JTBDUX thinking.
