Black Red Red

The Stroop Effect test demonstrates how interference causes the brain to experience a slower processing time because it is trying to sort through conflicting information it is receiving from outside sources.

This test looks at the overall effect on an individual of doing these interference tasks. You can also measure other physiological effects of the Stroop Effect on the body: increased sweating, increased heart rate, increased respiration – all of which can be typical signs of stress.
