Benefits of ambidexterity

Hypothesis: ambidextrous people learn more if they switch hands during writing something compared to if they use a single hand.

Test: relatively simple recall testing with a sufficient population of ambidextrous people divided into four populations (left hand no change, right hand no change, midway change from left to right, midway change from right to left)

Implication: it may be the case that there is potential value in teaching all children to be ambidextrous if the learning dividend is sufficient.
