Surprise (emotion)

Surprise is a quick feeling.

It happens when something is not what you expected. It can be a happy surprise. It can also be a bad surprise.

When you are surprised, your body reacts fast. Your muscles might feel tight. Your eyes may open very wide.

Your eyebrows might go up high. Your jaw might drop down. These things happen in a tiny flash.

Sometimes, surprise helps you pay attention. It tells you to look at something new. It can even help you get ready to run or fight.

Surprise is a feeling that everyone has.

Surprise is a very fast feeling.

It happens when reality is different from what you expected. This gap between what you thought would happen and what actually happens causes surprise. It can be a good thing, like a birthday party. It can also be a bad thing, like a parking ticket.

Your body has a quick way to react to surprise. This is called a startle response. It helps you stop what you are doing to look at something new. Your muscles, like those in your neck, may feel tight. If the surprise feels like a threat, your body may use a fight-or-flight response. This lets out adrenaline, which gives you power to run or fight.

You can see surprise on a person's face. Their eyebrows often go up high. Their eyelids open wide. Their jaw may drop down.

Sometimes, your pupils, the black circles in your eyes, will change size. This happens very quickly. If you see the same surprise many times, it might not feel as strong. This is because you begin to expect it.

Surprise is a very fast feeling in our minds and bodies.

It happens when what actually happens is different from what we expected. This creates a gap between our assumptions and reality. Surprise can be a good thing, like a surprise birthday party. It can also be a bad thing, like getting a parking ticket.

Some experts, like Paul Ekman and Carroll Izard, call it a basic emotion. They believe surprise is something all humans are born with. It is a natural way for people in every culture to react to the world.

When surprise hits, your body uses a quick way to react. This is called the startle response. Its main job is to stop what you are doing. It helps you turn your attention to something new and important. This happens extremely fast in the body. For example, a loud noise can reach a part of the brain called the pons in just 3 to 8 milliseconds. The full reflex can happen in less than two tenths of a second.

If the surprise feels like a threat, it might trigger a fight-or-flight response. This releases adrenaline to give you energy to run or fight.

Scientists have studied how people show surprise using their faces. The most common sign is raising the eyebrows high. This often creates horizontal wrinkles across the forehead. You might also see eyelids open very wide. This can show the white part of the eye, called the sclera, above and below the iris. Another sign is a dropped jaw where the lips and teeth part. Sometimes, the black circles in the eyes, called pupils, will change size. This is known as mydriasis when they get larger or miosis when they get smaller.

Many things can cause a person to feel surprised during a conversation. This is often explained by the Expectancy Violation Theory, or EVT. This theory says three things change our expectations. First, there are traits of the people talking, like their age or appearance. Second, there are environmental variables, like the place or the time. Third, there are social norms or rules for how people should act. If someone breaks these rules, you will feel surprise. A person might even use loud words like shouts or gasps to cause this feeling.

Surprise is linked to how we learn about the world. When we are surprised, it can show us that we do not know something. This can be a doorway to gaining new knowledge. However, if you see the same surprise many times, it feels less intense. This is because you become familiar with it. For instance, you might expect a scary part in a movie. Because you expect it, the surprise is not as strong as it was the first time.

Understanding surprise helps us understand how we react to everything around us.

Surprise is a rapid and fleeting mental and physiological state. It occurs when there is a gap between our expectations and reality. This gap represents the difference between our assumptions about worldly events and how those events actually turn out. Surprise can have any valence, which means it can be positive, negative, or neutral. A positive surprise might be a surprise birthday party. A negative surprise could be receiving a parking ticket. Because it helps us notice new things, it is considered an evolutionarily adaptive emotion. Experts like Paul Ekman and Carroll Izard include surprise in their taxonomies as a primary or basic emotion. They suggest that surprise is innate and universal across all human cultures.

Physiologically, surprise is closely linked to the startle response. The main function of this response is to interrupt an ongoing action. It reorients our attention toward a new and potentially significant event. This process involves an automatic redirection of focus. For a brief moment, this causes tension in the muscles, especially in the neck. This response happens extremely fast within the body. For instance, a loud noise can reach the pons, a part of the brain, within 3 to 8 milliseconds. The full startle reflex can occur in less than two tenths of a second.

If the surprise is perceived as a threat to survival, it can trigger the fight-or-flight response. This occurs when a person perceives a harmful event, an attack, or a threat. The body responds by releasing adrenaline to provide a boost of energy. This energy allows the individual to either escape or fight the perceived danger. This specific reaction generally has a negative valence. While the core appraisal of surprise is that something is new, the way we cope with the event determines our next feeling. For example, how we appraise our coping mechanism can lead to further feelings of confusion or interest.

Humans express surprise through several distinct facial features. The most distinctive and predictable sign is the raising of the eyebrows. This action often creates horizontal wrinkles across the forehead.

Another common feature is the opening of the eyelids. The upper lid raises and the lower lid draws down. This often exposes the white sclera above and below the iris. You may also see a dropped jaw where the lips and teeth are parted. The intensity of the surprise is often associated with how much the jaw drops. Spontaneous surprise is often expressed for only a fraction of a second. It may be followed immediately by fear, joy, or confusion.

Other non-verbal responses involve the movement of the pupils. This is known as mydriasis when the pupils dilate, or expand. It is known as miosis when the pupils constrict, or get smaller.

Some studies suggest that pupil dilation can indicate positive valence. Other studies suggest that dilation is actually a sign of general autonomous arousal. This means it happens during both positive and negative stimuli. Beyond the face, surprise can be influenced by voice inflection, pitch, and volume. Factors like distance, time, and the quality of eye contact also play a role. These cues help define the degree and the type of surprise being felt.

In interpersonal communication, surprise is explained by the Expectancy Violation Theory, or EVT. This theory suggests that three main factors influence our expectations. First, interactant variables involve traits like age, sex, race, and appearance. Second, environmental variables include the surroundings and the timing of the interaction. Third, interaction variables involve social norms and cultural norms. A violation of one or more of these factors can cause surprise. For example, a person might use verbal violations like shouts, screams, or gasps. According to Language Expectancy Theory, we develop norms for how language should be used. When these norms are broken, surprise occurs.

Surprise can also lead to significant changes in how we view others. EVT proposes that positive violations can increase the attraction of the person causing the surprise. This can enhance their credibility, power, and persuasiveness. For example, if a person with low credibility makes a very persuasive argument, it can cause a positive surprise. This can change a listener's beliefs or emotions. Conversely, negative violations may decrease these same qualities. It is also important to note the role of familiarity. As people become accustomed to certain types of surprises, the intensity of the feeling decreases. If you expect a certain event, such as a jump scare in a movie, the violation of expectation is smaller. This makes the resulting surprise much less intense.
