Recent experimental research highlights young children's selectivity in learning from others. Little is known, however, about the patterns of information that children actually encounter in conversations with adults. This study investigated variation in parents' tendency to focus on testable evidence as a way to answer science-related questions…

Reports the results of one study in which parents taught their two- to four-year-olds basic and superordinate concepts, and another, in which they taught them subordinate concepts. Parents' teaching styles were analyzed in terms of their usefulness for children who are attempting to learn about principles of hierarchical classification. (AS)

Contrary to the basic-level restraint hypothesis, which suggests that young children learn basic-level words more easily than specific-level words, these five studies show that although other constraints on word meaning may be in place, children are flexible in interpreting new words at different hierarchical levels.
