A general measure of organization in free recall for variable unit size and internal sequential consistency

A general procedure that can be applied to any type of free recall data for the quantitative measurement of subjective organization intertrial repetitions (ITRs) is described. The procedure makes it possible to examine any unit size with any type of internal consistency criterion. The application of this procedure and the corresponding expected value formula to four distinct data measurement cases is described, and several applied subjective organization measures are discussed. In addition, the relationship of clustering as a special case of subjective organization is demonstrated.
