Asymmetry of Odd-ball P3

Data files (MS-Excel) contain the grand-average ERP wave data,
shown in Figure 2 of the reference article (Target/Standard:
Inverted/Upright face and novel 3D object and vice versa).
The continuous electroencephalographic data were epoched into 900ms
data (-100 to +800ms from stimulus onset) and baseline corrected 
(-100 to 0 ms), recorded using the international 10-20 system 
referenced to linked earlobes, sampled at 200Hz and processed 
with a 30Hz low-pass filter (Butterworth filter of the 10th order).
