What are the basic psychological needs of students according to the Montessori method?

The basis of Montessori is the idea that children need to learn how to do things that interest them, and to be taught properly when they show an interest (the example is that it is not creative for a child to saw on a violin, but if you teach the child to play violin, then they may create music). Montessori is big on independence and freedom with responsibility, as well as enabling the child to make choices and feel in control of their education.
