Key Eye- Tracking Metrics in Cognitivie and Emotional Assessment

Fixations andD Dwell Time

Fixation is insights intro what system too process information from a pecular location. Fixation duration, frequency, and satisat l distribution provide insights intro what captures attention and how petrly information is processed. Longer fixations typically indicate deeper processinging or greater difficiente extracting information, while the estail faxations revevals thesequence and priorititief of informatiof terintion thering.

In emotional assessments, dwell time on emotionally charged stimusoni indicate emotionale accement or avoide pacans.

Saccades andScanpath Patterns

Saccades are rapid eye movements that occur between fixations, allowing thee eye to quicklic focus from on e location to anotherin. Sacade amplitude, velocity, and frequency provide information about visual search strategies ande the efficiency of information gathering.
