The relationship among motor tasks on the Whitener Motor Performance Battery of Tests was determined. The sample included 208 preschool children from white, middle and upper socio-economic class families.

Four factors extracted for the 3-and 4-yr. age group were "Total Body Strength and Leg Power," "Arm and Shoulder Power and Gross Coordination," "Rhythmic Coordination," and an "Unknown" factor. For the 5-and 6-yr. age group, five factors were named: "Rhythmic Coordination," "Arm and Total Body Strength," "Speed of Movement and Power," "Gross Motor Coordination" and "Dynamic Balance."
