  The explosive growth of online misinformation, such as false claims, has
affected the social behavior of online users. In order to be persuasive and
mislead the audience, false claims are made to trigger emotions in their
audience. This paper contributes to understanding how misinformation in social
media is shaped by investigating the emotional framing that authors of the
claims try to create for their audience. We investigate how, firstly, the
existence of emotional framing in the claims depends on the topic and
credibility of the claims. Secondly, we explore how emotionally framed content
triggers emotional response posts by social media users, and how emotions
expressed in claims and corresponding users' response posts affect their
sharing behavior on social media. Analysis of four data sets covering different
topics (politics, health, Syrian war, and COVID-19) reveals that authors shape
their claims depending on the topic area to pass targeted emotions to their
audience. By analysing responses to claims, we show that the credibility of the
claim influences the distribution of emotions that the claim incites in its
audience. Moreover, our analysis shows that emotions expressed in the claims
are repeated in the users' responses. Finally, the analysis of users' sharing
behavior shows that negative emotional framing such as anger, fear, and sadness
of false claims leads to more interaction among users than positive emotions.
This analysis also reveals that in the claims that trigger happy responses,
true claims result in more sharing compared to false claims.
