Document Summary
Top performers value sleep: musicians rated sleep as part of performance improvement, top ones nap more in afternoon then group of music teachers, duration of napping decreased during weekend (for leisure activities) Sleep strengthens memory in 2 ways: reduced interference from other tasks, consolidates memory leading to sleep based improvement without further practice. Sleep protects information from interference: paired associated learning tasks, wake group & sleep group (a-b list, sleep or wake, a-c list, a-b test, sleep is better then awake. Stability plasticity dilemma: during sws (between wake and rem sleep) active system consolidation integrated newly encoded memories with pre-existing long-term emeries. Encoding-> long-term store active system consolidation synaptic consolidation: naps are good and work well, sleep deprived brain functions differently and learns less effectively. R = reward ps = probability of success. If ps = 0, doesn"t matter what reward is. R=2, ps=0. 2, v= 0. 4: ps will never exceed 1.
