I took Communications in college. However, I also worked in Special Education dealing with those with Intellectual disabilities and Behavioral Issues. One of the Non Verbal communication indications for myself and others I worked with was to look at their EYES! Why because Nurses would check the eyes, blood pressure, temps, but the first thing we notice is the eyes will change. We can tell when a person is about to have a behavior, try to destroy their surroundings. We can see anger, fear, sorrow, sadness, disappointment, anxiety, and more. I hope this helps. The answer is based on my college studies, personal experience working for State. I majored in Communications
