A principle of development based on studies of infant behaviour that recognizes that the infant is equipped and capable of facing the world on a frontal plane of symmetry and could become perfectly ambidextrous. It suggests that a person comes to prefer the use of one hand, foot, or eye mainly because of the preference for the right hand in our culture, and not because the individual is incapable of learning with the left. Neurologically speaking there is equal facility for developing either side of the body, e.g. right or left-handedness. This is demonstrated where an injury forces a person who is normally right-handed to use the left hand, and also by people who are right-handed for one skill and left-handed for another.
