The power of imagination

Chin may be pulled back , a common gesture observed when a person feels threatened. Some emotions, such as fear, joy, sadness and anger, may be primary, making them easier to read. Joshua Susskind from the University of Toronto has found that expressions of fear and disgust are adaptive and serve to alter the experiences of our senses. Wide eyes, raised eyebrows and a mouth pulled back toward the ears are probably on your list. Lips are stretched horizontally towards the ears. In some people, h orizontal wrinkles may be seen on the forehead produced by the raising of the brows but these are different from the fear wrinkles that are produced when the eyebrows are raised as well as drawn together. Facial expressions are massively important for the social lives of humans and it should come as no surprise that some parts of our brain are dedicated to interpreting the small shifts in facial muscles that betray our emotions. When volunteers had to rapidly switch their gaze between two small circles, the fearful ones moved their eyes much more quickly than their disgusted peers. Show someone a piece of rotting food and their reaction will be visibly similar the world over. Click here for a list of additional resources. Suskind suggests that these adaptive expressions were then recruited for the purposes of social communication. For example, experts who study facial expressions consider smugness to be a mix of contempt and enjoyment.

Description: In fact, most people can easily differentiate between other facial expressions but when it to comes to the facial expressions of fear and surprise, they often confuse one with the other. The wrinkles appear on the area between and just above the eyebrows. Suskind suggests that these adaptive expressions were then recruited for the purposes of social communication. As a further test, Suskind asked volunteers to fixate on the centre of a projection screen, while a gray dot flashed ever closer to the centre of their field of vision. Some emotions, such as fear, joy, sadness and anger, may be primary, making them easier to read. Fear creates a need for watchfulness to detect potential threats and fearful expressions help with this by widening the eyes and nostrils to increase the information available to the senses. The mouth may or may not be open but the lip stretch is always there. The more intense the fear, the more will be the lip stretch. But they do at least provide support for the idea that our expressions originally developed to modify our perceptions, an idea first proposed by Darwin over a century ago. The former is very much about expanding features like the eyes, nostrils and mouth, while the latter involves scrunching these up.
