Correlations between behavioral and neural measures of action observation and motor imagery. a The number of trials performed during the AO task was negatively correlated to the years of experience participants had in their respective crafts (p = 0.050). b The number of trials performed during the AO task was positively correlated to the ratings provided at the end of each AO block (p = 0.000). c During the AO task the number of trials performed was negatively correlated to alpha power (p = 0.016). d The ratings provided at the end of each AO block were positively correlated to clarity ratings during the KMI task (p = 0.025). e iAPF was positively correlated between the AO and KMI tasks (p = 0.000), and between the AO and VMIQ-2 tasks (p = 0.000). Statistical analyses (Pearson correlations) were performed on the average values of each plotted variable collapsed across time (if applicable), electrodes, and groups. Regression lines are shown for visualization purposes only, as the data were not subject to a regression analysis, and include a solid line (shaded with a 95% confidence interval) for the overall correlation (i.e., collapsed across all conditions), dashed lines for ballet dancers, dot-dash lines for non-ballet dancer, and dotted lines for non-dancers. Individual data points are represented as squares for ballet dancers, triangles for non-ballet dancers, and diamonds for non-dancers
