Remembering and understanding: The effects of changes in underlying knowledge on children's recollections

This study was designed to explore the influence of changes in children's k nowledge on earlier constructed memories. Kindergartners' (N = 102) recall of a series of stories was examined as a function of their interpersonal kn owledge about the main story character. Children's knowledge about the prot agonist was manipulated prior to presentation of the stories, and the effec ts of their impressions on story recall were examined. A change in some of the children's impressions was then promoted, and the impact of this second knowledge manipulation on recall of previously heard stories was assessed. The results indicated that children's story recall was affected by their p rior impressions. Moreover, following the second knowledge manipulation, ch ildren revised their story reports in ways that were consistent with their newly acquired impressions, which suggests that they had reconstructed thei r memories of previously heard stories. These findings provide evidence for both prospective and retrospective effects of knowledge on memory.
