Cognitive function reflects how the brain processes information in real time: how we focus, remember, decide, and respond. These processes are supported by specific brain networks. When those networks are engaged by cognitive tasks, their activity is expressed through the eyes.
Eye movements and pupil responses are controlled by the same brain networks that support cognition. Pupil dilation reflects cognitive effort. Fixation duration reflects how much processing the brain is dedicating to a piece of information. Saccade timing reveals how decisions are being made. These signals are continuous, involuntary, and measurable.
ViewMind captures these signals during validated cognitive tasks, producing a simultaneous measure of physiology and cognition. That combination is what makes it possible to detect subtle functional changes that task scores alone cannot reveal.
