ABSTRACT
The present experiment is similar in principle to those involving the remembrance of transitive and associative relations (Chapters 5 and 6): the child is shown a series of operations, is asked to anticipate the results and, immediately afterwards, is invited to recall or reconstruct what he has seen. However, in the earlier cases, the actions themselves were quite simple, and the sole problem was their combination. Hence, there was nothing in the relations between these actions and their results to appeal to imagination or to stimulate the powers of figurative recall. In the present case (Figure 46), on the other hand, the action, i.e. the rotation of a triangle through 180°, and its results, i.e. the reversal of the position and direction of three arrows (blue, green and red) are intimately related and might therefore be expected to give rise to correct visual memories even in the absence of operational understanding.
