Can Training to Become Ambidextrous Improve Brain Function?

Can training to become ambidextrous improve brain function? Although teaching people to become ambidextrous has been popular for centuries, this practice does not appear to improve brain function, and it may even harm our neural development. Calls for ambidexterity were especially prominent in the late 19th and early 20th centuries. For instance, in the early 20th century English propagandist John Jackson established the Ambidextral Culture Society in pursuit of universal ambidexterity and "two-brainedness" for the betterment of society. This hype died down in the mid-20th century as benefits of being ambidextrous failed to materialize.
