Why might people in collaborative discussion begin to raise their voices? they do not listen. they have nothing valid to say. they are most likely lying. they feel like they are not being heard.

The correct answer is: they feel like they are not being heard.

If people raise their voices in a discussion it usually means that they are afraid of not being heard. It may mean acoustically ( the room is full of people and the level of noise high ), but also verbally ( they feel people don't understand their point of view ). Raising their voice does not always mean they are angry or upset. It is a defense mechanism because they may be passionate about the subject they talk about and they want the listeners' attention. They hope to create more impact with a louder pattern of speech.

Sometimes people raise their voices if they don't have a valid argument for their discussions. They fear intimidation may be the only way to get their message across even if the message is not correct.
