Figure 1.
Illustration of the experimental design used in the present experiment.
Stimuli were presented auditorily via loudspeakers. The learning phase lasted 5.5 minutes and the order of the tests was counter balanced across participants.
Figure 2.
Percentage of correct responses.
Group performance in the linguistic (green) and musical tests (blue) for musicians (left) and nonmusicians (right). The error bars represents +/− Standard Error.
Figure 3.
Grand average (Fronto-Central region) across musicians (A, left) and nonmusicians (B, right) recorded during each time bin of the exposure phase.
(black = 1st time bin, red = 2nd time bin, green = 3rd time bin, blue = 4th time bin). (C) Map showing the distribution of the N400 component (350–550 ms latency band, averaged across time bins and groups).
Figure 4.
N400 mean amplitude (350–550 ms) averaged across 6 fronto-central electrodes in both groups of participants (musicians in blue, nonmusicians in red) and in the four time bins (1'20'') from the exposure phase.
Negativity is up. Error bars refer to confidence intervals computed as described in [48] and take into account inter-subject variability, separately for each group.
Figure 5.
Scatter plot of accuracy in the behavioural test versus the time bin showing the maximum N400 amplitude.
Regression index and the p value are provided on the plot. Musicians are represented in blue and nonmusicians in red.
