Surprise (emotion)

life science Maturity 11-13 Next article →

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.
