In page Surprise (emotion):

"

Surprise does not always have to have a negative valence. EVT proposes that expectancy's will influence the outcome of the communication as a confirmation, behaviors within the expected range, or violation, behaviors outside the expected range.[3] EVT also postulates that positive interactions will increase the level of attraction of the violator, where as negative violations decrease the attraction.[4] Positive violations would then cause positive surprise, such as a surprise birthday party, and negative violations would cause negative surprise, such as a parking ticket. Positive violations of surprise may enhance credibility, power, attraction, and persuasiveness, where as negative violations of surprise may reduce credibility, power, attraction, and persuasiveness.[3]
