Eye Tracking in Cognitive Experiments

Eye tracking as the name suggests involves tracking of eye-movements. It is a non-invasive, sensitive tool that quantifies and measures eye-movements to describe an individuals' cognitive state. An eye-movement between two fixation points is called a saccade, which is one of the fastest motor movements in our body. By observing the profiles of these eye movements, scientists can better understand neural deficits in patients with cognitive impairments. In this video, we will first look at an...

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University In a staggeringly complex and engaging world, it is crucial to selectively process some stimuli at the expense of others. Experimental psychologists call this ability attention. Specifically, visual attention refers to the ability to selectively process aspects of a visual scene. Many paradigms used to study visual attention involve brief, punctuated, and repeated trials. However, everyday situations often place sustained demands...

Eye tracking has long been used to study gaze patterns in typically-developing individuals, but recent technological advancements have made its use with clinical populations, including autism, more feasible. While eye-tracking young children with autism can offer insight into early symptom manifestations, it involves methodological challenges. Suggestions for best practices are provided.

Continuity comes from associating detected anatomical keypoints across successive frames. The system links locations belonging to the same person, allowing researchers to retain individual identity while following motion trajectories over time. This temporal association turns separate frame-level observations into an organized record of movement, supporting analysis of changes in posture, gestures, locomotion, and activity patterns.
Keypoints provide a structured representation of the body that can be measured consistently across images or video. Locations such as the head, shoulders, elbows, hips, knees, and ankles capture the arrangement of major body parts, making visible movement easier to quantify. Their coordinated positions help researchers examine posture, gestures, and locomotion rather than relying only on general visual impressions.
Pose tracking converts visible body movement into quantitative measurements that can be followed over time, whereas manual observation does not by itself provide this structured measurement. The resulting data can support behavioral classification and continuous monitoring while reducing reliance on observers’ moment-to-moment judgments. This makes it possible to connect measured movement patterns with biological or cognitive processes studied in behavior research.
Researchers can examine posture, gestures, locomotion, social interactions, and broader activity patterns by analyzing the positions and trajectories of body-part keypoints. Because the representation follows movement over time, it can describe both individual actions and changes in how people move in relation to one another. These measurements provide behavioral evidence that can be analyzed quantitatively rather than treated as isolated observations.
A typical workflow begins with images or video containing the behavior of interest. Algorithms identify anatomical keypoints for each visible person, including major joints and the head, then associate those points across successive frames. The resulting identity-preserving trajectories form a structured movement record that researchers can use to quantify posture, gestures, locomotion, interactions, or activity patterns.
The approach is useful when a study needs quantitative, continuous information about visible movement across time. It can support behavioral classification, monitoring of activity patterns, and analysis of social interactions or locomotion without depending solely on manual observation. In addition, movement measurements can help researchers investigate relationships between observable behavior and underlying biological or cognitive processes.
