ABSTRACT
This chapter describes target two learning principles that have been identified by researchers as having greater learning potential in memory-impaired patients-vanishing cues and spaced retrieval (SR). It considers the evidence that speaks to their effectiveness both relative to standard trial-and-error, or errorful, and errorless (EL) learning. The chapter also describes that how do the more successful learning principles compare in their effectiveness. It also considers the value of EL learning principles for memory rehabilitation based on the studies? On this question, the data allow us to make two recommendations: First, if one is to choose between these principles then EL learning and SR should be prioritized based on evidence that these produce the greatest memory enhancement in patients with acquired brain injury and dementia, most consistently. Second, if one needs to be more targeted and choose between these two principles, then SR appears the best for the present, though primarily for patients with mild to moderate impairment.
