The psychopathology of everyday art: a quantitative Study - World ...

Colour: Red, Yellow and Brown are distinguished by *T* (meaning transformed). The
normal distribution was achieved by taking the square root transformation; the lower
values were pushed from zero (no red) towards 1 (colour in every part of the picture).
The greatest effect was to compress the latter half of the scale (half covered - fully
covered), so that a score of 0.75 reveals that half the picture has the colour in it. The
dotted line indicates a half way point on each plot. The plots are divided in two. The
upper section shows those groups showing significant differences, with the differential
single group in bold, and the whole group is marked '*'. Where there are two differences,
there are two bold differentials; group* first, the second group is marked ''.

for variable RED *T*
