The effects of the first five unscaled principal components on the face.

<p>The average faces shown correspond to mean PC score and mean PC score ± 3 standard deviations. The averaging was performed for the faces with PC score within ‘mean ± 0.5 SD’ as well as ‘< mean −2.5 SD’ and ‘> mean + 2.5 SD’, respectively.</p
