Three- and 4-year-old children were asked to judge which of a set of 3 lines was the longest, both independently and in the face of an inaccurate consensus among adult informants. Children were invariably accurate when making independent judgments but sometimes deferred to the inaccurate consensus. Nevertheless, the deference displayed by both age…

Children were able to solve problems that are logically impossible to solve on the basis of nontemporal information. (Author/RH)

Two experiments investigated why perceptual pretraining facilitates children's performance on concept problems involving a nonpreferred relevant dimension and preferred irrelevant dimensions. (JMB)

Reports on a study in which children aged 7 to 9 years and 11 to 13 years were asked to judge which one out of three wooden blocks would float, given weight and volume information for each block relative to a block that was known to float. Indicates that judgments may have been based on the size-weight illusion. (HOD)
