Verbal testimony about reality status is critical but often contradictory. These studies address whom children consider reliable sources of information about reality and how they evaluate conflicting testimony. In Study 1, seventy 4- to 8-year-olds heard an adult or child provide testimony about how to cook food and use toys, and about the reality of unfamiliar entities. Children selected the adult for food and the child for toys. Six- and 8-year-olds also selected the adult regarding reality. In Study 2, ninety 4- to 8-year-olds heard conflicting reality information from children and adults. Six- to 8-year-olds endorsed adult and child claims differentially and stated that adults knew more. By age 6, children favor adult testimony about reality over that of children.
