ABSTRACT
Historically, it reminds us of Piaget's apprenticeship with intelligence tester Theodore Simon and his first decade as a psychological researcher. Besides, Piaget is not endorsing Spearman's cognitive theory, in which 'correlate' had a very broad meaning.

In some passages in this chapter, correlat comes closer to Spearman's original usage, in which case it will be translated as 'the analogue', 'the missing item', or 'the item that completes the analogy. With analogies we will see that the developmental trend is the same.
