Phonological false memories in children and adults: Evidence for a developmental reversal

Abstract

False memories created by the Deese/Roediger–McDermott (DRM) procedure typically show a developmental reversal whereby levels of false recall increase with age. In contrast, false memories produced by phonological lists have been shown to decrease as age increases. In the current study we show that phonological false memories, like semantic false memories produced by the DRM procedure, show a developmental reversal when list items converge on a single critical lure. In addition, effects of list length were observed in adults and older children but not in the younger children, again mirroring effects previously observed in semantic false memories. These findings suggest that differences in list structure underlie the divergent developmental trajectories previously reported in semantic and phonological false memories. The findings are discussed in relation to theories of false memory and theories of spoken word recognition.
