Surprise
pronunciation (help·info) is a brief emotional state that is the result of experiencing an
unexpected relevant event.
Surprise can have any
valence; that is, it can be neutral, pleasant, or unpleasant.
[citation needed] Accordingly, some would not categorize surprise in itself as an emotion.
[citation needed]Surprise is expressed in the face by the following features
Spontaneous, involuntary surprise is often expressed for only a fraction of a second. It may be followed immediately by the emotion of fear, joy or confusion. The intensity of the surprise is associated with how much the jaw drops, but the mouth may not open at all in some cases. The raising of the eyebrows, at least momentarily, is the most distinctive and predictable sign of surprise.[1]
