Cognitive stress refers to the emotional and physiological response to uncontrollable and unpredictable situations.
Our metric of cognitive stress is a composite measure of acute stress brought on by demanding cognitive tasks under both time & social pressure.
Every day, we continuously scan the surrounding environment focusing on faces of people we meet, words we read, images on a package, moving vehicles when we cross a street and a variety of other objects. Visual attention is experienced as alertness and the conscious direction of attention towards task-relevant visual stimuli.
Engagement measures the level of immersion in any stimuli. Engagement may increase on immersion into stimuli that may be either positive or negative in nature. Engagement has been seen to decrease on boring, mundane and automated cognitive processes.
