Eye movement monitoring (or eye tracking) reveals where in space the eyes linger, when and for how long. Here, we demonstrate how eye tracking can be used to investigate the integrity of memory in multiple participant populations, without requiring verbal, or otherwise explicit, reports.

The visual world paradigm monitors participants' eye movements in the visual workspace as they are listening to or speaking a spoken language. This paradigm can be used to investigate the online processing of a wide range of psycholinguistic questions, including semantically complex statements, such as disjunctive statements.

Simultaneous Eye Tracking and Single-Neuron Recording to Identify Target-Selective Neurons

2025
The video demonstrates an assay to identify target-selective neurons via simultaneous eye-tracking and single-neuron recordings. A human participant is tasked with identifying a target object among an array of objects in a display, and the eye movement is tracked. Simultaneously, single neurons' firing rate is recorded via electrodes implanted in the brain. The data from both recordings are correlated to assess the presence of target-selective neurons.

Eye-tracking to Distinguish Comprehension-based and Oculomotor-based Regressive Eye Movements During Reading

The method was designed to investigate the role of inhibition of return (IOR) in regressive eye movements during reading. The focus is on differentiating between regressions triggered as a result of comprehension difficulty versus those triggered from oculomotor error, including the role of IOR in the two types of regressions.
FAQs
Infrared illumination helps the tracker identify two image features: the pupil and the corneal reflection. Their detected positions provide the visual references needed to calculate gaze position over time. This optical signal-processing step converts video frames into a time-varying record of where the participant is looking, supporting later analysis of shifts, fixations, and tracking behavior.
Recorded gaze data become more informative when analyzed as movement parameters rather than as a visual path alone. Saccade direction and velocity characterize rapid shifts, while fixation duration describes how long gaze remains relatively stable. Together, these measures allow investigators to relate the timing and organization of eye behavior to visual attention, perception, and decision-making.
Eye movement recording can be synchronized with neural recordings or behavioral tasks, creating a shared temporal framework for analysis. Researchers can then examine whether changes in gaze occur alongside neural activity or task events. This linkage is important in neuroscience because it connects an observable sensorimotor output with the timing of cognitive processes such as memory and decision-making.
During video-based acquisition, infrared illumination is used to detect pupil and corneal-reflection information, after which the system computes gaze position and movement measures. The resulting data can be organized around saccades, fixations, and visual tracking episodes. This workflow provides quantitative records that can be aligned with behavioral tasks or other recorded signals.
For studies of perception and attention, fixation duration and saccade characteristics offer complementary evidence. Fixations indicate where gaze remains over time, whereas saccade direction and velocity describe how it moves between locations. Examining both can reveal how visual attention is organized during a task, rather than relying only on whether a participant looked toward a general target.
In reading research, gaze measurements can show how visual behavior unfolds across text, while decision-making and memory studies can use the same signals to examine task-related timing. The method is also relevant to brain disorders that affect oculomotor control. Across these applications, objective eye data provide a common behavioral measure for characterizing cognitive and sensorimotor function.
