Fig. 4: Behavioural performance.
From: Modulating sleep: slow oscillation and spindle stimulation effects on physiology and memory

Learning curves averaged across all participants (top row) and change in performance by condition for each behavioural task (bottom row), for (a) the declarative task (GLT), (b) the procedural task (MSL), and the complex task (piano learning), which was measured by (c) pitch accuracy and (d) rhythm accuracy. While all task metrics except piano pitch accuracy showed a global change over time across conditions, there were no significant interactions between Time and Condition for any task. Grey boxplots in the bottom row represent the main effect of Time averaged across all conditions. GLT Grid Location Task, MSL Motor Sequence Learning task, n.s.: non-significant.
