Some basic hand gestures include rubbing the palms together, clenching the hands together and having the tips of the fingers of both hands meet to create a steeple shape. These gestures are often used to express nonverbal emotions, whether consciously or unconsciously.
Rubbing the palms together is a gesture that is often used to express positive expectation. Some researchers have concluded that when a person clenches the hands together, it is an expression of frustration or suppressing the expression of a more obvious negative emotion. Speakers who hold their hands in a steeple shape are said to be expressing confidence when they are speaking or listening.
