  abstract  = {The present study evaluated the interaction between preference for a focus of attention and instructions for focusing attention. N = 42 experienced billiard players had to shoot a billiard ball into a target area and received a focus instruction either corresponding or opposite to their preferred focus of attention. Two-dimensional error scores of accuracy and consistency were obtained. Accuracy of performance increased between the first test phase without instructions and the second test phase with focus instructions, independent of preference or instruction. However, participants with a preference for an external focus receiving an internal focus instruction showed less consistent performance.},
