Perceptual Learning

A long-studied phenomenon in vision science in which repeated exposure to, or training on, specific perceptual features — color, orientation, spatial location, shape — produces durable improvements in a person’s ability to detect and discriminate those features. Perceptual learning is typically most effective when attention is directed to task-relevant features under top-down guidance. In accessibility, perceptual learning is a theoretical basis for training older adults to recognize manipulable UI components (buttons, icons) across changing interfaces, rather than memorizing step-by-step procedures.
