“…Although the memory impairment and atrophy are less severe in MCI-A than in AD, these alterations clearly indicate that there is a cognitive and biological rationale supporting the utilisation of similar cognitive training techniques in MCI-A and AD. Therefore, the selection of techniques such as errorless (EL) learning and spaced retrieval (SR), that have shown good preliminarily efficacy in AD (for reviews see Grandmaison & Simard, 2003;Sitzer, Twamley, & Jeste, 2006), seem well-justified in MCI-A. Briefly, EL consists of reducing or eliminating errors during the encoding phase (Wilson, Baddeley, Evans, & Shiel, 1994), whereas SR aims at gradually increasing intervals between recalls (Camp, 1989;Camp & McKitrick, 1992), thus facilitating retrieval.…”
