Memory consolidation during sleep does not benefit all memories equally.

We manipulated encoding strength along two dimensions-the number of item presentations, and success at visualizing each item, in a sample of 82 participants. Sleep benefited memory of successfully visualized items only. Within these, the sleep-wake difference was largest f
