Well i really like this question. I think hand eye coordination is a key role of the game, i feel as if mine transferred from baseball, i played at a collegiate level for a couple years......... but i feel golf is a motor function of body and brain. If you make 10,000 swings over time including range, your body creates a memory system there, how else can you make a swing on the same plane swing in and swing out. I may not be a LOW handicap but i think theres more to it than just seeing and hitting the ball, you have to develop a swing and over time your body will memorize the swing, thats why when tiger took his new swing at the end of 1999 it took him a year or so to be well in comfort with it. Butch Harmon told the press a few years back when he took Adam Scott that Adam had one of the squarest impacts he'd ever seen on some occasions within .009 percent of a degree. His only problem was one swing could be totally opposite of the next, and they spent nearly two years on the same swing before he finally felt at ease with that swing. I read that article in a golf journal not too long ago, it was talking about Plane Precision, swinging on the same plane every time. Just my thoughts
