Children’s natural conversations following exposure to a rumor: Linkages to later false reports

► We link children’s natural rumor mongering with later event memory. ► Rumor exposure can prompt children to engage in highly constructive rumor mongering with peers. ► The content of children’s natural post-rumor conversations can leak into later memory. ► Children’s rumor propagation differs as a function of age and informant (i.e., adult versus peer). ► Deeper and more inventive rumor mongering is associated with increases in later memory errors. Previous research has shown that children naturally propagate overheard false rumors and that the circulation of such information can induce children and their peers to wrongly recall actually experiencing rumored-but-nonexperienced events. The current study extends this work by recording 3- to 6-year-olds’ naturally occurring conversations following exposure to an erroneous rumor. Results indicate that, compared with children who overhear rumors spread by adults, those who pick up rumors from peers during natural interactions engage in deeper and more inventive rumor mongering. Moreover, the degree and originality of rumor propagation was linked with various qualities of children’s subsequent recollections at both 1-week and 4-week delayed interviews. Furthermore, compared with 3- and 4-year-olds, 5- and 6-year-olds naturally transmitted more novel and coherent embellishments of the rumor to their peers, and more of their false narrative reports during the interviews overlapped with their own and their peers’ utterances transmitted soon after the rumor was planted.
