Abstract: Developmental psychologists have shown a renewed interest in children's understanding of the concepts and moral judgments of lying and truth-telling since 1980s. The main reason of the recent upsurge is due to the fact that the study on this area has theoretical significance for current debates about children's theory of mind, and the universality of moral development. The present study tested the universal issues on the concepts and moral judgments of lying and truth-telling by children's evaluations of pro- and anti-social behaviors. The evidence presented here confirmed Sweetser's folklorist model.

Key words: children's lying, truth-telling, pro-and antisocial behaviors, moral evaluation
