The problem of assessing concrete transitivity of length is explored with a non‐verbal design employing nine sets of three sticks each. A training phase is used to establish the relevant variable to which the subjects must attend, to obtain a bead. A test phase consists of eight trials, in which the elements A, B , and C , are displayed in a systematic variation. A subject is said to display transitivity, when he more than five times in the eight trials chooses the largest of three sticks, A , on the basis of the information A > B and B 7< C. In a group of 20 children, varying in age between 52 and 80 months, half of the group, which is socio‐economically upper‐middle class, displayed transitivity. However, the youngest child displaying transitivity with six correct test‐trials was 5 1/2 years old. The youngest child displaying transitivity with eight correct trials was 6 1/4 years old.
