the other groups since no confidence interval takes in 1(low) or 3(high).
Structural variables
Line: was understood as a defining border: outlines, lines used in pattern, dots, writing,
broken line, straight ruled lines, and not blocks of colour intended for shading or close
patterned pencil lines for shading which were treated as blocks. It was rated light/thin,
varied (where thin lines appeared with thick), thick/heavy.
Line quality was split into painted and drawn lines for ease of rating, since where
pencil line coincided with painted line, the relative difference in thickness always
polarised the pencil to thin and the painted to thick, thus creating ambiguities in the
information. The scoring task asked for relative thickness of the lines within the picture.
The literature tends towards expectations of thick or heavy lines for patients.
Controls were expected to have more range, and substance abusers, speculatively, might
suffer difficulties in control similar to people with brain injury, which are said to produce
thin or shaky lines.
