Some Behavioral Characteristics of the Partial Seriators Reconsidered.

In this study the effects of the use of some of Piaget's criteria to make a distinction between partial and operational seriators were investigated. Therefore, attention was paid to three behaviorial characteristics in which the child constructed the series: concatenated transitive comparisons, the verification of transitive comparisons, and the number of self-corrections. Ss were 428 children from kindergarten and primary school, grades 1 to 6, who were observed while completing a set of six seriation tasks derived from Piaget's publications.
