The purpose of this paper is to examine the linearity and the change of the timeoutputting or insetting cylinders from or into a block and chronological age. Concretely, whatis the strongest linearity and the most changeful of the following three sorts of time?1. The time outputting all cylinders from a block.2. The time insetting all cylinders into a block. These cylinders were put in order beforeinsetting.3. The time insetting all cylinders into a block. These cylinders were put at random beforeinsetting.In this paper I use the data which appeared in Otoda's paper(1978). Subjects arestwenty-eight normal children, from two years to five years seven months old.In order to examine the linearity I calculate the Pearson's moment correlationcoefficient. In order to examine the change I calculate the regression coefficient.In conclusion, the linearity of the time insetting all cylinders which were put at randominto a block is the strongest, and its rate of change is the hardest.When the Montessori cylinder block is used as a screening test material for childpsychological development, the time insetting all cylinders which were put at random into ablock is most useful.
