The development of cognitive judgment in the mentally retarded: a selective review of Piagetian-inspired research.
Five categories of cognitive judgments were discussed, relative to Piagetian levels of development, as follows: time, weight conservation, Type I illusions (Poggendorf), moral judgment, and color discrimination. Normative research and the mentally retarded in five areas of these judgments was reviewed, with additional suggestions for research being offered.
