Abstract: Grasping and functionally interacting with a relatively large or awkwardly shaped object requires the independent and cooperative coordination of both limbs.Acknowledging the vital role of visual information in successfully executing any prehensile movements, the present study aimed to clarify how well existing bimanual coordination models (Kelso et al, 1979; Marteniuk & Mackenzie, 1980) can account for bimanual prehension movements targeting a single end-point under varying visual conditions.We therefore, employed two experiments in which vision of the target object and limbs was available or unavailable during a bimanual movement in order to determine the affects of visual or memory-guided control (e.g.feedback vs.feed forward) on limb coordination.Ten right-handed participants (mean age = 24.5)performed a specific bimanual prehension movement targeting a solitary, static object under both visual closed loop (CL) and open loop 2s delay (OL2) conditions.Target location was varied while target amplitude remained constant.Kinematic data (bimanual coupling variables) and contributions so kindly given in order to aid the completion of this project.• The Participants -for the time and effort that they generously gave.• Dr. Gord Binsted -for his advice and guidance.His generosity with his time and knowledge was greatly appreciated.• Kyle 'fat-head' Brownell -for his technical expertise, assistance and friendship in all aspects of my Canadian life.• Tyler Rolheiser & Andrei Georgescui -for their constructive criticism and treasured friendship.• CPAL Friends -for keeping me sane and for being a constant reminder that things could be a lot worse.• University of Saskatchewan Track and Field Team -for all their individual love and companionship as well as their collective attitude and spirit towards life which has changed me indefinitely.An inspiration to us all.• My family -for all their love and reassurance.• Trevor Clarke -for all his immeasurable patience,
