สรุป	Pupillometry is the measurement of changes in pupil size in response to cognitive, emotional, or perceptual stimuli. The pupil automatically dilates (mydriasis) during mental effort, emotional arousal, or approach-related states, and constricts (miosis) during relaxation or withdrawal. First documented systematically by Hess in the 1960s, pupillometry provides an objective, continuous measure of cognitive load, attention, and emotional response that complements behavioral and self-report measures.	Eye-tracking analysis is a method for recording and quantifying eye movements and gaze patterns during visual tasks, providing direct measures of visual attention, comprehension, and cognitive processing. Advancing from mechanical devices to high-speed infrared cameras, eye tracking enables researchers to identify where people look, for how long, and in what sequence—revealing cognitive processes underlying reading, scene perception, decision-making, and attention.
