AbstractThe effects of within-versus between-languages (English-French) study and test on rates of bilingual children's and adults' true and false memories were examined. Children aged 6 through 12 and university-aged adults participated in a standard Deese-Roediger-McDermott false memory task using free recall and recognition. Recall results showed that: (1) both true and false memories increased with age, (2) true recall was higher in within-than between-languages conditions for all ages, and (3) there were fewer false memories in between-languages conditions than within-language conditions for the youngest children, no differences for the 8-and 12-yearolds, and by adulthood, there were more false memories in between-languages than withinlanguage conditions. Recognition results showed that regardless of age, false recognition rates tended to be higher in between-languages than within-language conditions. These findings are discussed in the context of models of false memory development.Keywords: DRM paradigm, false memories, bilingual memory, memory development, children's false memory.
Development of False Memories in Bilingual Children and AdultsPast studies using the Deese-Roediger-McDermott (DRM) paradigm (Deese, 1959;Roediger & McDermott, 1995) have demonstrated that young children may be less susceptible to false memories than adults (Brainerd, Reyna, & Forrest, 2002;Howe, 2005Howe, , 2006 Howe, Cicchetti, Toth, & Cerrito, 2004; but see Ghetti, Qin, & Goodman, 2002). Theoretical explanations such as fuzzy-trace theory (FTT) have attempted to account for these findings by suggesting that both verbatim and gist traces are encoded during list presentation (Brainerd & Reyna, 2005). These traces are qualitatively different from each other where the former is concerned with item-specific surface information and the latter with meaning-based information. It is this gist trace that is thought to be responsible for false recall in the DRM paradigm. Although young children are capable of extracting these types of traces, the ability to do so improves with age and cognitive development into later childhood and early adulthood (Brainerd & Reyna, 2005).An alternative, associative-activation model (e.g., Howe, 2005Howe, , 2006, in press) argues that developmental trends in false memories occurs not just because of correlated changes in children's meaning extraction skills (i.e., growth in knowledge base) but also because of increased automaticity in the activation and accessibility of those concepts and associations in the child's knowledge base. These increases in automaticity are brought about by additional exposure and proficiency using these concepts as well as the associations between related concepts. As exposure and proficiency increases, so too does the automaticity of activation of concepts and their associative links, making false memory production more and more ad...
