Test Using Name to Assert Authority

QUESTION 1: What is the effect of addressing a person by name in a moderate manner?

Because it's a sign that the conversation isn't serious
Because we like to hear our name repeatedly
Because in our childhood, our parents and teachers used it to get our attention or correct us
Because it is a social norm without psychological background

In trivial and unimportant conversations
When we want the message not to be taken seriously
When we do not wish to project authority
In situations where you need the other person to understand the seriousness of the situation
