摘要：The efect of REST (Reduced Error Semantic Therapy) on word retrieval was compared with a hierarchical cuing intervention requiring overt speech. Prior work suggests that the intensive practice and decreased opportunity for error provided by REST may provide improved word retrieval equivalent to that of conventional methods (Davis，Harrington, and Baynes, 2006). This computer-based method is intended as an adjunct to traditional therapy that is amenable to use on a home computer. This study compared the eftctiveness of two methods difering only in whether or not production was required. To understand whether either method of training had an efèct on the organization of semantic fields, the flags-task developed for use with persons with Alzheimer’s disease was used to compare semantic judgments to a normative group (Ober and Shenaut，1999).
