Abstract: Role-differentiated bimanual manipulation requires each hand to perform different, but complementary, actions on one or more objects. It is usually considered to be a late-developing high- level motor and cognitive skill involving the coordination of the two hemispheres of the brain. The frequency of role-differentiated bimanual manipulations was recorded in a longitudinal sample of 24 infants tested at 7, 9, 11, and 13 months during play with 10 different toys. Role differentiation was observed as early as 7 months, and its frequency was unaffected by toy characteristics. Role-differentiated bimanual actions increased with age, and the type of toy did influence the likelihood of eliciting role differentiation between 9 and 13 months.
