Video Scan Alignment Subtest
The video scan alignment subtest displays two successive screens: The first screen is a pattern of horizontal
and vertical lines, which should be straight and evenly spaced. The second screen is a pattern of boxes
(arranged in columns and rows), which should have straight borders and be evenly spaced.
Figure 3 and
Figure 4 , respectively, show examples of the first and second video scan alignment subtest screens.
