Main Sequence Relationships, Task Load, and Cognitive Load

The term main sequence relationship with regards to human eye movements describes the relationship between duration, peak velocity, and magnitude of human saccades. These relationships have been established on individuals under normal cognitive conditions, and previous studies have found no significant difference between main sequence relationships in ADHD and non-ADHD individuals. This work further explores main sequence relationships, specifically if they hold when individuals are experiencing various levels of task load produced from a variety of stressors and if they hold between individuals with different cognitive styles. The advance gaze measurements used in this study were generated from multiple eye tracking datasets utilizing the Real-Time Advanced Eye Movements Analysis Pipeline (RAEMAP). The advance gaze measurements were also used to predict task load and cognitive style, along with being feature ranked to determine which measurements are the most impactful in the predictions. The results give insight into the relationships between task load, cognitive styles, main sequence relationships, and advance gaze measurements
