U. Tan, AMOUNT OF ASYMMETRY IN GRASP REFLEX DEPENDS ON THE GRASP REFLEX OF THE LEFT HAND IN HUMAN NEONATES, Perceptual and motor skills, 78(1), 1994, pp. 80-82
Grasp-reflex strengths from right and left hands were measured in 33 h
uman neonates. There was no significant correlation between right minu
s left grasp-reflex strength and grasp-reflex strength from the right
hand. The grasp-reflex strength of the left hand was negatively linear
ly correlated with the right minus left grasp-reflex strength. It was
suggested that the right brain may be the main determinant for the mot
or asymmetry in hands.
