The primary purpose of this study was to determine the degree of relationship, if any, between two different methods of measuring motility. Seashore (4) and others have used motility as a means of measuring skill such in musical performance. Ream's technique (3) for measuring motility has been criticized on the grounds that it is possible for a subject to tense his muscles and thus obtain a spuriously high score from involuntary tremor under certain conditions. Similarly some subjects tend to tense themselves and thus to introduce hindrances in function which seems to lower their score. It is thought that these discrepancies indicate a fault in the measurement of motility when using the Ream method.
