Dimensionality reduction techniques in pupillometry research: A primer for behavioral scientists
Abstract The measurement of pupil size is a classic tool in psychophysiology, but its popularity has recently surged due to the rapid developments of the eye-tracking industry. Concurrently, several authors have outlined a wealth of strategies for tackling pupillary recordings analytically.
