The first video describes research done by the University of Toronto, which found that common facial expressions such as fear or disgust not only show how a person is feeling, but also alter the environment around oneself. According to the researchers these common emotions were found to adjust the way we use our senses. A question being asked during the research process was whether or not a person can see better when they feel fearful of something, causing their mouths and eyes to open wide. After performing a number of tests, the researchers found that open eyes and mouths allowed more of the world in, quicker visual recognition of objects and also increased air intake without extra effort. The video goes on to describe that these findings are consistent with the fact that the expression of fear improves information gathering in reaction to something that might harm you, while the expression of disgust hinders sensory input. The second video is a very insightful look into how to spot people that are lying to you. In the video, a polygraph examiner interviews people and points out certain signs that may indicate whether or not that person is lying. According to the polygraph examiner, “eyes are the windows to the soul”. He also explains that if a person is looking up and to the right that person is making up something because they are visually thinking about something that only exists in their imagination. Looking up and to the left means that the person is trying to remember something, however this formula is opposite for left-handed people. Shifty eyes, leaning back in a chair, sitting to the side, crossed arms or keeping the hands tightly gripped are also signs that may detect lying.
