The sensitive periods comprise one of several basic principles on which Montessori early childhood education is founded.
Montessori wrote about these intense interests as sensitive periods. We might say that the sensitive periods furnish energy for the child to explore specific areas of the environment and to master certain skills at precise time periods. Montessori said: “It is this sensibility which enables a child to come into contact with the external world in a particularly intense manner. At such a time everything is easy; all is life and enthusiasm. Every effort marks an increase in power.”
