This study, which assessed hypothesis-testing abilities using a discrimination-learning paradigm, found that 16 language-impaired primary-level children solved fewer problems than 16 controls equated on cognitive level, but the 2 groups used similar hypothesis types to solve the problems. Type of verbal feedback (explicit versus nonexplicit) did…

Examined the relationship between 7-, 9-, and 11-year old children's performance on a battery of selected Piagetian measures and on a proportional reasoning task. Found a strong relationship between stage level and (1) the complexity of hypotheses used, (2) the use of the proportional hypothesis, and (3) the overall use of logical hypotheses. (HOD)

Three studies of children at two developmental levels were made to assess subjects' understanding of the verbal terms "easy" (to do) and "hard" (to do).

Describes a study designed to determine if college students' success in writing computer programs is related to level of cognitive development as described by Piaget, verbal ability, and mathematics reasoning. Regression analysis showed that level of cognitive development, when combined with verbal reasoning, is linearly predictive of programming…
