Many photographers regard smiling as a non-distinguishing facial expression.  National Geographic has reported that people remember vacations and events a happy experiences even if they weren’t as long as they reflect smiling individuals.

Marianne LaFrance, a Professor of Psychology at Yale University, shared with National Geographic her thoughts, experiences and cool facts about smiles.

She states that smiles are ambiguous because they appear in an array of contexts.  However, she notes that people should smile because smiles have beneficial psychological effects.  “Human beings need  viable relationships with other people in order to survive and thrive.  Smiling is an important device that helps us make and maintain these crucial social relationships.”

Past studies have shown that even just holding a pencil or pen in your mouth, simulating as mile, can improve a person’s mood.  See below for three interesting facts on smiling.

1.  Babies smile in the womb.

2.  People who are guilty of some transgression such as cheating on an exam are more likely to be given the benefit of the doubt if they are shown to smile in a photograph versus showing a neutral expression.

3.  Bereaved spouses who showed smiles while talking about their loved one shortly after his or her death were better off at both six months and twelve months later than those who did not show some smiling immediately following    their loss

4.  Asian countries such as Japan, the Philippines, and Thailand tend to smile the most and Northern European countries such a Russia, Poland and Scandinavia tend to smile the least.

 Enjoy your day and remember to SMILE !

Several people have asked us to comment on a recently published and publicized study entitled “Body Cues, Not Facial Expressions, Discriminate Between Intense Positive and Negative Emotions” by Hillel Aviezer, et al.

The Paradigm

The paradigm used in Aviezer’s research involved judgments of emotion when viewing stimuli that combined different emotional reactions in different parts of the body and face to examine whether one part of the body influences emotion judgments more than the other.

Methodology

For his study (from a Wired Magazine article), Aviezer and his colleagues showed photos of professional tennis players to 45 Princeton University students, randomly divided into three groups of 15. Each tennis player had just won or lost an important match, and the participants rated the players’ contorted facial expressions from negative to positive on a scale from 1 to 9, with 5 marking the neutral midway point. One group of participants looked at head-to-toe photos of the players, the second group looked at only the players’ bodies, and the third group looked at only their heads. Only the final group had trouble making the correct identification.

Interpretation of Data

Aviezer and his colleagues interpreted that data to mean that facial expressions alone didn’t tell them whether the players were joyous or in despair. They also suggested that people read intense emotion more effectively by looking at a person’s body language than by watching their facial expressions.

Taking a Critical Look

Humintell Director Dr. David Matsumoto is an expert in the field of culture, emotion, and nonverbal behavior. He has published over 400 works on these topics. We asked him to comment on the study and share some of his thoughts.

While Dr. Matsumoto states it is an interesting paradigm that Aviezer uses, he also sees two major problems with the research.

1.    The research involved the use of Photoshop and modern technology to alter photographs of individuals. Research participants were  shown three different types of photographs:  Head -to-toe photos of athletes, photos of only the athlete’s bodies, and photos of only the athlete’s head.  The researchers cut and pasted different heads to different bodies as well as just displayed the bodies and heads separately and asked participants to decided what emotion was being displayed.

This type of research doesn’t consider whether those stimuli mean anything in real life; where you would encounter just a human head creating an expression, or just a human body gesturing without seeing their face in a real life situation?

This brings up a valid question of, if the items being shown do not occur in real life, what is it that is exactly being studied? What data is being generated? Dr. Matsumoto believes that we need to address questions about the technology before jumping to conclusions about what the data means.

2.    During this experiment, the researchers showed research participants several faces of athletes who had immediately won (or lost) something in an achievement or competitive context. Unfortunately, the researchers base their study upon the assumption that the expression people make at the time they scored or lost a point is a universal expression of happiness or anger when in fact, there is no data to support this statement.

Recent research has shown that the face of an athlete (at the moment of a win or loss in a competitive context) used in this study may or may not be representative of one of the seven basic emotions. In fact, some research suggests that the emotions that are being felt at that exact moment of winning in a competitive context may best be called triumph and not happiness or joy.

Dr. Matsumoto states if the image that was shown during the study is not representative of one of basic emotions, then showing that particular face says nothing about basic emotions. Moreover, the results of the study also cannot be used to argue against the universality of the seven basic emotions of anger, contempt, disgust, fear, happiness, sadness and surprise.

Misconceptions

It is important to note that there is a major misconception that the seven universal facial expressions are the only expressions that occur on the face, which is simply not true.

As mentioned in Dr. Matsumoto’s book Nonverbal Communication: Science and Applications,

“The face is arguably the most prominent nonverbal channel, and for good reason. Of all the channels of nonverbal behavior, the face is the most intricate. It is the most complex signaling system in our body and it is the channel of nonverbal behavior most studied by scientists.“

However, this does not mean that the face is the only channel of expression for all emotions.
