Factorial Analysis of Precision, Steadiness and Equilibrium in Fine Motor Skills

摘要

To provide a representative sample of fine motor psychomotor skills emphasizing precision, steadiness, and equilibrium, a battery of eleven laboratory instruments was devised, all having automatic scoring on electric counters. These tests provided a total of twenty-six measurements analyzing such factors as the effect of standing or sitting posture; sense modalities or vision, audition or equilibrium; and movements in two or three dimensions. The two studies on this project report correlations from three groups of psychology students factorially analyzed by separate groups with quite consistent identification of seven group factors underlying precision of motor performances.
