There Is More To Smile Than You Know!

There Is More To Smile Than You Know!

Till date facial emotional expressions were restricted to state of being happy, sad, angry, afraid, disgust, and surprise. Scientists from Ohio State University confirm through study based on a new software program that it is more complex than that. The study on 230 student volunteers, were made to react on verbal cues designed to trigger their emotional response and analyze their facial expressions. The participating 100 males and 130 females were mapped for no less than 21 emotional states. China’s Xinhua has reported the development of the study stating that US researchers have found out 21 expressions through which researchers can identify the origin of emotions in brain.

The eminent scientist heading this research, Dr. Aleix Martinez from Ohio State University comments, “We’ve gone beyond facial expressions for simple emotions like ‘happy’ or ‘sad.’ We found a strong consistency in how people move their facial muscles to express 21 categories of emotions”. This research is remarkable as it tells us how 21 ways of expressions are common and nearly expressed in every culture. This will help researchers to understand the mental wellness of patients suffering from autism, schizophrenia and post traumatic stress disorder.

The results of this study are published in the Proceedings of the National Academy of Sciences where scientists have linked the facial expressions to the genetic and chemical pathways that govern the emotional responses in brain. Apart from the six standard emotional reflexes known so far scientist could see the responses for “angrily surprised”, “sadly surprised”, “happily disgusted”, “sadly angry” and many more. Martinez with his dedicated team including Shichuan Du and Yong Tao have expanded the library of expressions and included complex reaction by using Facial Action Coding System (FACS).

As time rolls we can hope that this research and similar ones would give scientists the platform to understand difficulty understood emotions and more human and computer interaction study.
