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.
We are surrounded by sounds, noises and voices. Being able to focus on particular auditory stimuli is crucial for our everyday life. Whenever we are engaged in a conversation with someone, we can direct our auditory attention to what the other person says without being distracted by other sounds.
