Abstract:

This project was designed to answer a series of questions involving extended practice on motor skills tasks. The tasks employed were video games, and principal interest was focused on whether 1 performance late in practice involves fewer underlying factors than early in practice 2 video games coverge or diverge differentially upon one another and 3 factorial content of the games changes with practice. Thus far, the research has resulted in two reports. The first is a theoretical paper addressing the issue of how best to smooth correlational data. Two methods of smoothing Pearson rs were investigated. The first was to average repeated measures in blocks then correlate block averages. In the second method all repeated measures were correlated then the correlation coefficients were averaged in blocks. The latter approach proved much superior resulting in greatly reduced sampling variability, and little distortion in the population correlation estimated. The second paper examined the question of late appearing factors that should occur after a switch from controlled to automatic processing. If differential factors associated with automatic processing exist, they could only be observed after this shift occurs.
