Mozart

The Mozart effect
As per an internet web site “Neuroscientists have intensified their research into music and its role in the developing brain”. This is partly due to evolving diagnostic techniques and technology, and due, also, to the growing awareness of the probative opportunities presented by such studies.
The "Mozart Effect", has been bandied about by popular print and broadcast media. It is featured in parenting, education, and music oriented publications, and in the mainstream general press. While it has renewed interest in classical music, education and focused much deserved attention on the general field of childhood development to help others to improve their skills.
A set of research results that indicate that listening to Mozart's music may induce a short-term improvement on the performance of certain kinds of mental tasks known as reasoning. Popularized versions of the theory, which suggest that "listening to Mozart makes you smarter", or that early childhood exposure to classical music has a beneficial effect on mental development.
To test the Mozart effect I believe that will be a good idea to take statistics in a population with people of different ages and take a measure of the connectivity ability, because if it works it could be implemented in the future to create positive and clever people and a better world with trained humans.
