Which key principle of developmental systems theory underlies the observation that certain experiences bias children from birth to be predominantly left- or right-handed, but the process of development of hand preference can be delayed or even reversed (e. g., from left to right or right to left) within the first 5 years of postnatal development?

This principle give obeservation that certain experience bias can be made to be delayed or it could be reversed within this first 5byears period
