KEATING, DANIEL P. Precocious Cognitive Development at the Level of Formal Operations. CHILD DEVELOPMENT, 1975, 46, 276-280. Early adolescents (fifth and seventh graders) classified by psychometric testing as bright and average were evaluated on Piagetian tasks of formal operations in order to examine the relationship between brightness and precocity. The bright group evidenced formal operations far more frequently than the average groups of the same age. Thus the major finding was that brightness psychometrically defined implies cognitive developmental precocity within the stage theory of Piaget.
