Résumé :

It is widely believed that sleep is essential to the consolidation of learning and memory. The theory of sleep-dependent consolidation (Walker and Stickgold 2004) suggests that after an offline period including sleep, performance improves more than after a period without sleep. Accordingly, several studies showed the critical role of sleep in skill and procedural learning consolidation (Fischer et al. 2002; Stickgold et al. 2000; Walker et al. 2002). However, recent works suggest that the data on which this theory relies, may be driven by several factors that are unrelated to sleep. In this talk, Dezso Nemeth (Professor of Psychology, Hungarian Academy of Sciences & Eotvos Lorand University, Budapest, Hungary & IMÉRA – Titulaire de la Chaire Langage et Cerveau) will present 6 experiments that failed to show sleep-dependent consolidation in procedural learning. This cumulative evidence invites a reconsideration of sleep’s theoretical role in the consolidation of
procedural memories.
