Formal operational thought, in general, involves the ability to think in the abstract, the ability to combine and classify items and the ability to use high-order reasoning skills. Formal thinkers methodically vary one factor at a time and hold the other factors constant as they keep track of each test result.
Additionally, the quality of their symbolic play can have consequences on their later development. The most prevalent tests are those for conservation. Adolescence, 21 84 , 751—765.
