Levels of Availability of a Formal Operational Strategy.
Stone, C. Addison; Day, Mary Carol
Child Development, v49 n4 p1054-65 Dec 1978
A modified version of Inhelder's and Piaget's bending-rods task was administered twice in succession to 9-, 11-, and 13-year-olds. Subjects were then categorized as spontaneous, latent, or nonusers of the formal operational control-of-variables strategy according to whether they used the strategy on the first, second, or neither administration.
