title: Children's use of mental state information in selecting persuasive arguments.
abstract: Whether and when children use information about others' mental states to invent or select persuasive strategies were examined. In Study 1, preschoolers, 3rd-graders, and 6th-graders (ns = 11, 12, and 16, respectively; 17 girls) were told about story characters' persuading parents to buy pets or toys. Children were either given or not given information about story parents' beliefs and asked to invent or select appropriate arguments. Older children, but not preschoolers, used belief information to select arguments. Results were replicated in Study 2 (16 kindergartners, 16 3rd-graders; 19 girls). In Study 3, kindergartners and 1st-graders (N = 16; 6 girls) reasoned well on false-belief tasks but not on persuasion tasks, suggesting that failure to consider mental states in persuasion was not due to lack of a belief concept. Findings suggest that mental state understanding may continue to develop after the preschool years; methodological qualifications are also considered.
