Reality Construction

Surprise is intimately connected to the idea of acting in accordance with a set of rules. When the rules of reality generating events of daily life separate from the rules of thumb expectations, surprise is the outcome. Surprise represents the difference between expectations and reality, the gap between our assumptions and expectations about worldly events and the way that those events actually turn out. In essence, surprises are the end result of predictions that fail.

Body Language

Surprise is expressed in the face by the following features:
  • Eyebrows that are raised so they become curved and high.
  • Horizontal wrinkles across the forehead.
  • Open eyelids: the upper lid is raised and the lower lid is drawn down, often exposing the white sclera

Despite facial feedback hypothesis
Facial feedback hypothesis
The facial feedback hypothesis states that facial movement can influence emotional experience. For example, an individual who is forced to smile during a social event will actually come to find the event more of an enjoyable experience.-Background:...

 (facial display is necessary in the experience of emotion or a major determinant of feelings); in the case of surprise, research has shown a strong dissociation between the facial display of surprise and the actual emotional experience of surprise. This suggests that there are variations in the expression of surprise.

Physiological Response

The physiological response of surprise falls under the category of the startle response. The main function of surprise or the startle response is to interrupt an ongoing action and reorient attention to a new, possibly significant event. There is an automatic redirection of focus to the new stimuli and, for a brief moment, this causes tenseness in the muscles, especially the neck muscles. Studies show that this response happens extremely fast, with information (in this case a loud noise) reaching the pons
Pons
The pons is a structure located on the brain stem, named after the Latin word for "bridge" or the 16th-century Italian anatomist and surgeon Costanzo Varolio . It is superior to the medulla oblongata, inferior to the midbrain, and ventral to the cerebellum. In humans and other bipeds this means it...

 within 3 to 8 ms and the full startle reflex occurring in less than two tenths of a second.

Surprise has one core appraisal-appraising something as new and unexpected-but new appraisals can shift the feeling of surprise or shift the emotion of surprise to another emotion. Appraising an event as new predicts surprise, but the appraisal of the coping mechanism predicts the response beyond surprise, such as confusion or interest. As shown in Figure 1.
