Identification accuracy in percent correct in Experiment 2.

<p>The left panel shows T1 performance, and the right panel shows T2 performance, given that T1 was correctly responded to (T2|T1), plotted as a function of T1-T2 Lag.

Identification accuracy in percent correct in Experiment 1.

<p>The left panel shows T1 performance, and the right panel shows T2 performance, given that T1 was correctly responded to (T2|T1), plotted as a function of T1-T2 Lag. Black symbols represent the identity task and white symbols represent the color task. Solid lines represent high memory load and dotted lines represent low memory load.</p

Identification accuracy in percent correct in Experiment 3.

<p>The left panel shows T1 performance, and the right panel shows T2 performance, given that T1 was correctly responded to (T2|T1), plotted as a function of T1-T2 Lag. Black symbols represent the condition without priming and white symbols represent the condition with priming. The remaining figure conventions are identical to those of <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0016696#pone-0016696-g002" target="_blank">Figure 2</a>.</p

Visual experience for different movement styles.

<p>y-axis: z-transformed ratings of visual experience (mean ± SE). x-axis: visual experience of ballet spectators (N = 12) in black columns, Indian dance spectators (N = 9) in grey columns, and novices (N = 8) in light grey columns for different types of performances (ballet, Indian dance, and acting control). The ratings confirmed our experimental groups: the level of acquired visual experience was dependent on the spectator group. *** = significant at <i>P</i><0.001, * = significant at <i>P</i><0.050.</p

Action observation.

<p>y-axis: z-transformed MEP amplitudes (mean ± SE, N = 29). x-axis: rest (eyes closed, black columns), ballet (light stripes), Indian dance (bold stripes), and acting (dots) in ECR (left) and FDI (right). *** = significant at <i>P</i><0.001, ** = significant at <i>P</i><0.010.</p

Performers' muscle group activity during the dance pieces.

<p>Arm (ECR) and hand (FDI) activity of the ballet and Indian dance performer throughout the whole dance performances. x-axis: ECR (black column) and FDI (grey column) averaged across left and right body side for the ballet performer/ballet performance (left) and Indian dance performer/Indian dance (right). y-axis: standardized mean activities (z-transformed with a mean of 100 and SD of 1 for illustration purposes) compared to overall muscle activity of each performer (See <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0033343#pone.0033343.s002" target="_blank">Text S2</a> for detailed analysis description). *** = significant at <i>P</i><0.001.</p

MEP modulation by visual experience.

<p>y-axis: MEP amplitudes (z-transformed, mean ± SE, N = 29) of the forearm (ECR, left figure) and hand (FDI, right figure). x-axis: visually experienced ballet spectators (black columns), Indian dance spectators (grey columns), and novices (white columns) during watching ballet specific movements (left) and Indian dance specific movements (right) performances (each as a contrast to non-dance control performance). * = significant at <i>P</i><0.050.</p
