What is the difference between disconfirmation and confirmation?

Please provide the best answer for the statement.

Answer: Disconfirmation is a communication pattern in which you ignore a person’s presence as well as that person’s communications. You say, in effect, that the person and what she or he has to say aren’t worth serious attention. In confirmation, you not only acknowledge the presence of the other person but also indicate your acceptance of this person, of this person’s definition of self,
and of your relationship as defined or viewed by this other person. Disconfirming responses often lead to loss of self-esteem, while confirming responses often lead to gains in self-esteem.
