Document Summary
They gotta predict where the object is going, timing is important. Infants between 12 and 24 weeks and wanted to find out how well they reached moving objects at different speeds. He coded infants behavior, what age to they reach or just make contact what age did they grab it an how this behavior varied with diff speeds. Generally the number of times they just touched the object was very high when they were young. Grasp was low at young age but increased with age. Number of misses is constant across age, pretty low. They are pretty good at grasping a hold of the object at 16-20 weeks of age. They are successful at reaching a moving object at the same time as reaching and grasping a non moving object. Reaching by in large was predictive of these objects. We are talking about reaching with the hands, but in fact cant they reach with their feet.
