Experiment IV 144<br />
Figure 12-3 summarizes the f<strong>in</strong>d<strong>in</strong>gs for all four <strong>in</strong>vestigated ERP components. The<br />
chart <strong>in</strong> the upper panel shows (for all four ROIs) the amplitude <strong>of</strong> the ERPs from the<br />
music experiment (ERAN <strong>and</strong> N5), the lower panel conta<strong>in</strong>s the correspond<strong>in</strong>g data for<br />
the language experiment (ELAN <strong>and</strong> LSN). In the table below each chart, an overview<br />
<strong>of</strong> the results <strong>of</strong> the planned comparisons with user-def<strong>in</strong>ed contrasts is given. It is<br />
shown <strong>in</strong> which ROI the <strong>in</strong>vestigated ERP component was significant. Four different<br />
comparisons were reported at the table’s rows: It is <strong>in</strong>dicated whether a significant difference<br />
was found, <strong>in</strong> the first l<strong>in</strong>e for the mean <strong>of</strong> both groups, <strong>in</strong> the third l<strong>in</strong>e for the<br />
MT group, <strong>and</strong> <strong>in</strong> the fourth l<strong>in</strong>e for the NM group. In the second l<strong>in</strong>e, it was determ<strong>in</strong>ed<br />
if the amplitude <strong>in</strong> the MT group was larger than <strong>in</strong> the NM group.<br />
Figure 12-2 Scalp topographies <strong>of</strong> the <strong>in</strong>vestigated ERP components (ERAN, N5, ELAN, <strong>and</strong> LSN). The<br />
topographies are a spherical spl<strong>in</strong>e <strong>in</strong>terpolation <strong>of</strong> the amplitude difference between either<br />
irregular <strong>and</strong> regular chords (ERAN <strong>and</strong> N5) or syntactically <strong>in</strong>correct <strong>and</strong> correct sentences<br />
(ELAN <strong>and</strong> LSN). The time w<strong>in</strong>dows were the same as these used for statistical evaluation.<br />
In the upper panel the ERPs from the music experiment, <strong>in</strong> the bottom panel these from the<br />
language experiment are shown. For each ERP component the head plots from the children<br />
with musical tra<strong>in</strong><strong>in</strong>g (MT) are on the left side, the these <strong>of</strong> the children without musical<br />
tra<strong>in</strong><strong>in</strong>g (NM) on the right side.<br />

ERAN: An ERAN was elicited <strong>in</strong> response to the irregular compared to regular chords<br />
at the end <strong>of</strong> a chord sequence (see Figure 12-1). It was most prom<strong>in</strong>ent at the electrodes<br />
<strong>of</strong> the anterior ROIs <strong>and</strong> had a slightly higher amplitudes over the right (M=
