There are over 18 different smiles used by humans to show emotions, 99% of those smiles are actually fake and only one is real and shows real happiness. The Duchenne smile is the only one that shows genuine happiness. A simple way to understand a Duchenne smile is by imagining a 5-month-old baby smiling! The eyes become smaller, the cheeks are raised and the lips are opened enough to show teeth while smiling.

2. Withdrawn

4. Disbelief Or Disagreement

Taking time to open your eyes, covering your eyes, lowering your eyes during a conversation is a strong indication of disbelief, disagreement, anxiety, or dismay. As soon as you notice any of the eye actions above while in a conversation with someone, it’s time for you to stop talking and just let it go!

A very common sign of confidence and authority is when a man or a woman spreads or plants his/her fingertips on a table or surface while speaking, standing, or sitting. Another way to spot how confident a person is is by watching the thumps, if a person sticks his or her thumbs out of the pocket, this indicates confidence and authority as well.

8. Lying

Study shows that people who lie or are actively lying tend to use fewer gestures such as touching, making conversational gestures, or moving their arms and legs while speaking. In contrast, someone speaking the truth will make hand gestures, and naturally, move parts of their body as they normally would.

9. Distress & Weakness

A common sign of distress that is found in almost all cultures around the world is the act of wringing the hands. It also indicates that a person is concerned about the wellbeing of someone else. You can pinpoint the weakness of a person is by watching his or her thumb action, if he or she sticks her thumb in her pocket, this indicates weakness, low self-esteem, and confidence.

10. Dilated Pupils

Research shows that one of the main reasons why pupils dilate is because of interest. If a person sees something they like, the pupils dilate and if they are not interested in the object the pupils constrict. This is a very easy way to notice if your attitude is acceptable by others when in a gathering or while having a conversation with someone. 

11. Stealing

After researching thousands of thieves and shoplifters, researchers found that 98% of them had the same body language when caught in the act.

What Are The 4 Types Of Body Language?

There are many different types of body language or as researchers call it “nonverbal communication” used to determine a person’s intentions or thoughts but the 4 main types that are often used in most scenarios are body movement and posture, voice, eye movements, and eye contact and facial expressions. Gestures, touch, and space are other types of non-verbal communications as well.

Facial expressions such as sadness, happiness, anger, surprise, fear, and disgust are some of the most common body languages found in all cultures and parts of the world. Body movement and posture are simply how a person walks, sits, stands, or holds their head, and other subtle movements.

Eye contact or eye movements can show a person’s interest, affection, hostility, or attraction while the sound of one’s voice can indicate sarcasm, anger, affection, or confidence. 

Gestures, however, may have different meanings in different cultures, for example, the way a person waves may have a different meaning in Asia than it would in Europe. Pointing, beckoning, waving, and moving your hands when speaking or arguing are some of the common types of gestures used in nonverbal communication.

How Do Psychologists Read Body Language?

Psychologists read body language by studying the eyes of a person, gazing directly at the face, paying attention to proximity, watching out for mirroring, observing head movements, watching the person’s feet, looking at hand signals, and observing the position of the person’s arms.
