How Many Types of Smiles Are There? Smiles And Their Meaning

Over the years there have been many questions about the number of smiles that exist. The truth of the matter is that that number is too vast to catalogue. Here’s why.

The first thing to remember about reading faces concerns whether they are displaying an emotion or not.

Remember, emotions are reactions to events that are meaningful to someone and that potentially impact their survival. Thus, facial expressions of emotion go on and off the face relatively quickly.

Single episodes of normal emotional expressions that are not concealed (what we call macroexpressions) go on and off the face between 0.5 and 5 seconds.

Microexpressions (signs of concealed, suppressed, or repressed thoughts and feelings) occur less than 0.5.

Both macro and microexpressions are reactions, and this is true with smiles associated with emotions as well.

LEARN HOW TO READ MICROEXPRESSIONS

Genuine Smiles

When smiles are reactions (i.e., they go on and off the face) and they occur by themselves, they are likely to be signs of enjoyment, amusement, happiness, contentment, or some other positive emotion label (thus, there are as many labels for these smiles as there are positive emotion words in culture’s language).

When they are macroexpressions, these smiles are likely to be Duchenne smiles – genuine smiles that involve not only the lip corners being pulled up and diagonally but also the muscle around the eyes (orbicularis oculi).

This muscle raises the cheeks, stretching the skin and giving it a shiny appearance, and creates crow’s feet wrinkles at the side of the eyes for many.

When the reaction smiles are microexpressions, they may not have this muscle activated because micros can involve only parts of the full-face expression.

Reaction Smiles 

When smiles are reactions and they occur with other body movements, the smiles can signal other emotions.

For example, a reaction smile with head and gaze down and a hand to the face may be signs of embarrassment, shame, or humiliation (more emotion labels).

A smile with head tilted up, gaze up, chest puffed up, and hands on the hips (arms akimbo) may be signs of pride (and other synonyms of it).

Reaction smiles that occur with other facial expressions of emotion are interesting but the analysis is the same.

If the expression (including the smile) is a reaction, then there is likely positive emotion along with the other emotional expression. Thus, when a reaction smile occurs with a reactive angry expression, a person is likely experiencing an anger-enjoyment blend.

Smiles as Secondary Emotions

Then there are reaction smiles that occur sequentially (not blended) with other emotional expressions. Oftentimes the reaction smile might occur after another emotional expression.

These are what we call secondary emotions. What are secondary emotions? They are emotions that we have about other emotions.

Some people like the fact that they get angry and so they may smile after being angry (watch out for those people). Some people like to experience fear (think sensation seekers); they may smile after showing and experiencing fear.

These secondary emotions are the reason that horror movies are popular with a segment of the population.

Social Smiles

But smiles that occur with other emotional expressions are often not reactions; instead, they are what we call social smiles.

These are smiles that typically do not include the muscle around the eye and are not signs of enjoyment, amusement, or happiness emotional reactions; they are learned, voluntary smiles (but be careful; contrary to popular belief, many people can voluntarily produce Duchenne smiles).

Importantly, social smiles are not emotions; when they occur, they can stay on the face for a long time, much longer than four or five seconds.

And people can produce them anytime because they are used in all cultures as signs of politeness, pleasantness, courtesy, etc. (more smile labels).

Social smiles grease the wheels of all societies and cultures. Sometimes they look like they may be pasted on a person’s face (remember, they’re not reactions).

Smiles that Qualify or Comment on Emotion

When social smiles occur with other emotional reactions, they qualify or comment on those other emotions.

  • A social smile with an angry expression softens the display of anger.
  • A social smile with a sad expression (aka a miserable smile) says that even though you’re sad, things will be all right.
  • A social smile with a fearful expression says the same – even though you’re afraid, things will be OK.
  • And the pasted, asymmetrical smiles (aka smirks or dominant smiles, other labels) are signs of personality (arrogance, another label).

Then there’s all the social smiles that occur in the vast number of different contexts of life, many of which have been given cute names in the past. When you think about it, these are all tied to specific contexts.

Thus, there’s the all the different types of smiles you can read about elsewhere, such as:

  • Reward smiles
  • Affiliative smiles
  • Flirtatious smiles
  • Lonely smiles
  • Dampened smiles
  • Fake smiles
  • Wistful smiles
  • Polite smiles
  • Pan Am smiles
  • Chaplin smile
  • Forced smiles
  • Uncomfortable smile
  • Sarcastic smiles
  • Love smiles
  • Interested smiles
  • Seductive smile
  • Courtship smiles
  • Dazzling smiles
  • Etc. etc.

All of these are social smiles that may include other body movements (e.g., sideways look, touching the hair with the flirtatious smile) that occur in specific contexts. And some reaction smiles of enjoyment also occur in specific contexts, such as what is known as schadenfreude (joy in someone else’s misfortunes)

Because these are all labels of smiles that occur in a specific context, it goes to reason that there are as many possible smiles to interpret and label as there are the various contexts of life.

But the smile itself is always the same – lip corners up and diagonal.

What differs is whether that particular expression in that particular context is important enough in our culture and everyday language to give it a specific label. Words and phrases are symbols that depict real life phenomena in language so that we can talk about them, and cultures and language reify or lift up specific phenomena of life that are important to those cultures for whatever reason.

Thus, there’s probably a gazillion types of smiles out there if you tie a smile with a context and want to label it. Or only two – smiles of true positive emotions and social smiles.

How Does Music Affect Our Emotions? A Cross-Cultural Study

Emotions from Music

Most people know the power of music and the emotions music can invoke. Listen to a happy song with an upbeat tone and you may find yourself tapping your feet. Listen to a sad song and it may bring tears to your eyes.

In fact, research has shown that music can activate our autonomic nervous system and even cause shivers down the spine.

A fascinating new study also suggests that music’s power to unify emotions and movements may have played a role in human evolution, fostering social bonds and community.

Music and Emotion Research

The recent music and emotion research study out of Turku PET Center in Finland reveals that music’s emotional impact transcends cultures, evoking similar bodily sensations around the world.

Researchers found that happy music energizes arms and legs, while sad tunes resonate in the chest.

The results of the study entitled “Bodily maps of musical sensations across cultures” were on 25 January 2024 in the Proceedings of the National Academy of Sciences.

This cross-cultural study had a total of 1,500 participants who completed an online survey.

Western and Asian participants rated the emotions and bodily sensations evoked by Western and Asian songs.

The emotions and bodily sensations evoked by music were similar across Western and Asian listeners. The bodily sensations were also linked with the music-induced emotions.

“Certain acoustic features of music were associated with similar emotions in both Western and Asian listeners. Music with a clear beat was found happy and danceable while dissonance in music was associated with aggressiveness. Since these sensations are similar across different cultures, music-induced emotions are likely independent of culture and learning and based on inherited biological mechanisms,” says Professor Lauri Nummenmaa.

Similar to universal facial expressions of emotion, this recent musical study suggests that music’s influence on the body is universal across cultures. It also suggests people moving to music in all cultures and synchronized postures, movements and vocalizations is a universal sign for affiliation.

The researchers suggest that music may have emerged during the evolution of human species to promote social interaction and sense of community by synchronizing the bodies and emotions of the listeners.

Universal Emotions in Music

The idea that music produces universal emotional responses has been studied before.

Research led by Eline Adrianne Smit and colleagues from the MARCS Institute for Brain suggests certain elements of music are hard-wired into the human central nervous system.

Smit and colleagues asked musicians and non-musicians in Sydney, Australia as well as different communities from Papua New Guinea with varying degrees of exposure to Western music, to associate major and minor melodies with either happiness or sadness.

The researchers found that the degree of familiarity with Western music corresponded with the association between major melodies with happiness, and minor melodies with sadness.

 

 

This study suggests that familiarity through cultural exposure plays and important factor when associating major and minor melodies with happiness and sadness respectively.

Interestingly, major chords tend to appear more frequently than minor chords in popular music and research shows that humans are likely to attribute positive emotions to things that we are familiar with.

Free Webinar: The Basics of Social Influence

Dr. David Matsumoto, Director of Humintell, led a free webinar on The Basics of Social Influence where he provided participants with an introduction to evidenced-based topics of social influence.

These included the topics of:

  • Conformity, Compliance, and Obedience
  • Cooperation
  • Emotion Contagion
  • Social Loafing and Social Striving
  • Leadership
  • Persuasion and Influence

Conformity, Compliance, and Obedience

In social science and social psychology these topics (conformity, compliance and obedience) are generally considered together within the larger rubric of social influence.

They are all important constructs in any social system as ways of reinforcing behaviors.

Some of these words may have a negative connotation, but in reality they are important concepts for any group or society as ways of reinforcing behaviors.

Definitions of conformity, compliance and obedience can be found in the graphic to the left.

In this area of psychology there are a few studies that form the backbone of what we know about these three topics. Let’s explore them!

The Ash Experiments

A researcher named Solomon Ash conducted a very well-known set of experiments that are some of the first and classic studies on conformity and compliance.

In one of his most famous studies, a participant went into a room with seven confederates who were part of the experimental team.

The participants were given lines (see example). You can see there is a target line and other lines on the right hand side.

Every person in the room was asked which line on the right hand side matches the target line on the left. There was an obvious correct and incorrect answer.

The results of the study showed that when the participant is the last to answer and everyone before them has given the incorrect answer, it increases the likelihood that the participant will also give the incorrect answer.

On average 32% conformed to the incorrect answer. In over 12 trials, 75% conformed at least once.

The Milgram Experiments

Like the Ash experiments, any people have heard about the Milgram experiments led by Yale psychologist Stanley Milgram.

In one of his most famous studies (that could not be conducted today due to ethical reasons), Milgram recruited 40 men to come to a laboratory with equipment that was labeled with shock danger warnings.

The participant was told that they are the teacher who is going to deliver a shock to a student in a neighboring room. They couldn’t see the student (and who was not actually being shocked contrary to what the participant is told).

Every time the student answered a question wrong, the participant was instructed to deliver a shock to them of increasing intensity. The student in the other room banged on the wall, made other sounds, then eventually went silent.

The participants asked the experimenter if they should continue (to which they are told yes). In the study with 40 men, 26 delivered the maximum shock and 14 stopped before reaching the highest levels.

Like the Ash study, the Milgram studies demonstrates an amazing amount of conformity and obedience.

Over the years, these findings have been replicated many times all around the world in various countries suggesting that conformity, compliance and obedience may be universal human phenomenons.

Cooperation

Cooperation refers to people’s ability to work together towards common goals. Cooperation is necessary in every society and based on unique cognitive abilities, especially a concept called shared intentionality.

Dr. Matsumoto believes that shared intentionality is at the root of human cultures. He also believes that the main purpose and function of human communication including language and non-verbal behavior is to share intentions.

Cooperation is a universal phenomenon that is part of the basis of social influence. It has been studied extensively in social psychology.

However, there is some research that suggest there are cultural and individual differences in cooperation.

Some research suggests that the rates of cooperation tends to be higher in collectivistic societies (e.g. East Asia, SE Asia, Latin/South America) compared to individualistic societies (e.g. USA, Canada).

Additional research suggests that individual differences in cooperation exist due to levels of trustworthiness (high trusters vs low trusters).

Research on cooperation has also been conducted regarding the sanctioning systems across various cultures as well as inter and intra-cultural environments.

Dr. Matsumoto’s research suggests that when people from different cultures come together, they generally cooperate less.

Emotion Contagion

The concept of emotion contagion started with researcher Elaine Hatfield and others in 1993.

What is emotion contagion?

Emotion contagion is a phenomenon when someone’s emotions lead to or produce similar emotions in others.

What Hatfield and colleagues have demonstrated is when there’s a group of people, one person or several people’s emotions can affect the emotions of the rest of the people.

Why does emotion contagion occur?

The truth is that science has not gotten to the point where we know exactly why emotion contagion occurs.

However, there’s interesting literature within the emotion contagion literature that pertain to what’s called mirror neurons.

Mirror neurons are essentially special types of brain cells that are triggered when viewing the actions of other individuals. For example, when we see another person fall and hurt themselves, our mirror neurons trigger the part of our own brain that would be activated if we had fallen.

Facial feedback is another concept that suggests that when we have an expression on our face our brains tell us we’re having that emotion and thus turns our emotional system on inside of us.

This may be the reason why some research suggests that smiling can improve your mood. 

Social Loafing and Social Striving

When people are in a group and they have a task to do, sometimes individual productivity and motivation is reduced. This concept is called social loafing.

Social loafing has led to the concept of freeriders- members of a group who are not producing as much as others

On the other hand, there’s the opposite effect called social striving. Sometimes working in a group enhances individual performance rather than diminish it so then the product of the group is greater than the sum of the individual members.

One factor that has been shown to influence whether members of a group either loaf or strive is leadership.

Research has put issues faced by leaders into two buckets: 1) task performance and 2) group maintenance.

There has been extensive studies about the characteristics of leaders that are universally endorsed all around the world and the most influential set of researchers are known as the GLOBE project.

The GLOBE project has produced a number of amazing findings that are universally endorsed as good leaders are:

  • Charisma: ability to connect and persuade others
  • Team Orientation: focus on the team as a whole
  • Empathy: the degree to which leaders are perceived as being empathetic

Persuasion and Influence

Without a doubt, the most influential psychologist in the area of persuasion and influence is Robert Cialdini.

The seven psychological principles underlying persuasion, influence, and compliance that Cialdini has compiled are:

  • Reciprocity
  • Consistency
  • Social Proof (related to conformity)
  • Liking (related to cooperation)
  • Authority (related to obedience)
  • Scarcity
  • Unity

Cialdini has done an amazing amount of research himself but has also done a great job of integrating the knowledge in the field to come up with these various principles of persuasion and influence.

One of the points that Cialdini makes which Dr. Matsumoto finds absolutely true is that these principles exist because societies and cultures and all groups need them.

These principles work because they work to mobilize emotion, either through what’s known as cognitive dissonance or anxiety or something that motivates people to alleviate their emotion.

Other Social Influence Constructs

There are actually many other social influence constructs that have been demonstrated and documented in science including:

  • Mere Exposure Effect
  • Trust and Trustworthiness
  • Rapport
