It's in the details: The role of selective discussion in forgetting of children's autobiographical memories

This experiment investigated whether retrieval-induced forgetting (RIF) would be found in children's self-generated autobiographical memory recall. An adapted version of the RIF paradigm for adults' autobiographical memories was administered to 8- and 9-year-old children (N = 65). We hypothesized that RIF would be found in terms of both number of memories recalled and amount of memory detail reported. The relationship between memory detail at the retrieval practice phase and RIF magnitude was also investigated. Consistent with hypotheses, RIF was found for both the number of memories recalled and the amount of memory detail reported. In addition, memory detail at retrieval practice was associated with increased RIF magnitude. Findings extend the current literature in three ways. First, they indicate that selective discussion of autobiographical events with children can cause forgetting of similar non-discussed events. Second, even when these non-discussed events are recalled, they contain sparser memory detail. Finally, when events are selectively discussed in greater detail, forgetting of similar non-discussed events occurs to a greater extent.
