Abstract

This study examined the influence of body scale on the grip configurations used by young children (6-12 years old) to displace cubes that varied systematically in size (L) and mass (M). It was determined if the scaling relation we had developed for adults K = log Lc + ((log Mc)/(a + bLh + cMh)) where L(c) and M(c) is the length side and mass of the cubes, respectively, and L(h) and M(h) are the length and mass of the hand, respectively, it would also predict the change in grip configurations across this age range in a fashion consistent with the principle of similitude. The statistical and scaling analyses revealed that the invariant body-scaled relation that specified the adult grip transitions also held for the 6- to 12-year-old children.
