Training and extension of a memory strategy: evidence for utilization deficiencies in the acquisition of an organizational strategy in high- and low-IQ children.
143 9- and 10-year-old children were classified into high- and low-IQ groups and given 4 different sort/recall lists (baseline, training, near [immediate] extension, far [1-week] extension) to assess training and extension of an organizational memory strategy. All children received categorized items of moderate typicality for Phases 1, 3, and 4. For Phase 2, children were assigned to either a training or control group, with half of the children in each group receiving category typical items and the others category atypical items. Levels of recall, sorting, and clustering were greater in Phase 2 for high-IQ children, for the typical lists, and for trained children. Both the high- and low-IQ children trained with typical items continued to show high levels of recall on the near extension phase. No group of subjects maintained high levels of recall after 1 week, although levels of sorting and/or clustering on the extension trials remained high for all groups of subjects except the low-IQ control children. This latter pattern (elevated sorting/clustering with low levels of recall) is an indication of a utilization deficiency, a phase in strategy development when children use a strategy but gain little or no benefit in performance. The results provide evidence for IQ, training, and material effects in the demonstration of a utilization deficiency.
