Peer reviewedGratch, Gerald – Child Development, 1972
A six-month-old infant who can remove a transparent cloth from his hand when it is covered after he grasps a toy may not be able to remove an opaque cover. Alternative interpretations of the phenomenon, that is, degree of bimanual coordination and focus of attention, are discussed. (Author/MB)
