Continuous target-tracking psychophysics is an innovative experimental paradigm that has emerged as a powerful tool for studying perception, cognition, and visually guided behavior. This review outlines how continuous psychophysics complements traditional forced-choice methods by facilitating rapid data collection, providing insights into the real-time dynamics of perception and action, and enabling studies with special subject populations such as infants and patients. With its efficiency, conceptual simplicity, and ability to reveal temporal signatures of processing and performance, continuous psychophysics is poised to drive important advances across perception and cognitive science.
