The purpose of the present study was to examine the role of cognitive manipulation processes in serial ordering, such as comparisons of elements or rearrangements of lines, and their relations to cognitive abilities. The task was to order 10 sticks with respect to their length. The subjects were three, four, and five year olders. Two hypotheses were assumed that (1) the types of comparison were dependent on abstraction of dimensions, such as length, thickness, or color, from various attributes of objects (2) that the types of rearrangement are dependent on the presence of complete seriation-figure image. The significant correspondences were observed between the types of comparison and the scores of abstraction-comparison of dimension test, and between the types of rearrangement and the scores of figure comprehension test, and between the types of rearrangement and the scores of figure comprehension test. In addition, a scalogram analysis revealed that unidimensionality of scales in descending order, is (a) the abstraction-comparison of dimension test, (b) the presence of complete serration image, (c) appropriate comparisons, (d) adequate rearrangements, and (e) complete seriation.
