Perceptual matching task Both patients ( N = 7) and controls ( N = 6) had positive scores (1.098; SD : 0.28; 0.905; SD : 0.11), marginally greater for the patients' group, suggestive of a rightward bias, with some perceptual underestimation of left extent, with a trend toward significance (Mann-Whitney test: z = 1.79, p = 0.074).
