Are some types more inclinced to use laughter as a defense mechanism?
There are some people who tend to laugh when they're opening up about their problems for example or smile when talking about something bad that happened to them. My mother is a good example of this. People tend to think she is weird because she does this often. She would break down to tears if someone pointed it out that it's not funny. She doesn't think it's funny either, she just reacts that way to defend her emotions.
Could this be linked to the positive outlook triad or is it completely unrelated?
