The effects of stereotypes and suggestions on preschoolers' reports.

Children's (N = 176) reported memories of a strange man's visit were studied. Three- to 6-year-olds were interviewed repeatedly after the event in one of the following conditions: (a) control, in which no interviews contained suggestive questions; (b) stereotype, in which children were given previsit expectations about the stranger; (c) suggestion, in which interviews contained erroneous suggestions about misdeeds committed by the stranger; and (d) stereotype plus suggestion, in which children were given both pre- and postvisit manipulations. Results from open-ended interviews after 10 weeks indicated that control participants provided accurate reports, stereotypes resulted in a modest number of false reports, and suggestions resulted in a substantial number of false reports. Children in the stereotype-plus-suggestion group made high levels of false reports. All experimental conditions showed dramatic developmental trends favoring older children.
