The production of spontaneous false memories across childhood

• We test novel predictions about the development of spontaneous memory illusions.
• We find that standard developmental trends in memory illusions can be reversed.
• We also show that context effects and theme nodes underlie this reversal.

We found evidence that the usual developmental trends in children’s spontaneous false memories were eliminated using novel stimuli containing obvious themes. That is, children created more false memories than adults when scenes needed to be remembered. In Experiment 1, 7- and 8-year-olds had higher false memory rates than adults when using visual scenes. Experiment 2 showed that gist cuing could not account for this effect. In Experiment 3, children and adults received visual scenes and story contexts in which these scenes were embedded. For both types of stimuli, we found that children had the highest false memory rates. Our results indicate that the underlying theme of these scenes is easily identified, resulting in our developmental false memory trend.
