ABSTRACT
The act of striking a putt in golf involves manipulation of an implement, known as the putter, in order that it will intercept a ball (stationary though that ball is) with both sufficient accuracy and effort to enter a hole some distance removed. The maximum velocity the ball can have upon reaching the hole, if it is to drop, has been calculated at 4.3 feet per second (Biddulph, 1980). Few greens are flat, environmental conditions are seldom constant and the mental state of the performer can often be less than optimal, so a satisfactory interception is not a ‘given’. Where performers are highly motivated to perform near the upper limits of their ability dynamic interceptive actions are, in fact, subject to much psychological interference.
