| Abstract: | Utilization deficiencies occur when children experience little or no benefit in task performance from the use of a strategy. Miller and Seier (1994) found evidence for utilization deficiencies in over 90% of memory studies that evaluated spontaneous strategy use in children. In this article, we extend the concept of utilization deficiency to training studies and review nearly 30 years of memory-training research. We identified three different types of utilization deficiencies and evaluated 39 different studies with 76 separate conditions for evidence of utilization deficiencies (increases in strategy use with little or no corresponding increase in memory), production deficiencies (increases inbothstrategy use and memory performance), and unsuccessful training (increases inneitherstrategy use nor memory performance). Over half of all training conditions showed evidence of at least one type of utilization deficiency. Utilization deficiencies were more common for younger than older children and were more likely to be found when training involved multiple procedures (e.g., verbal instruction, rationale) rather than a single procedure (instruction only). The findings are discussed in terms of the need to broaden the concept of utilization deficiency and to reevaluate the process of strategy development. |
