U1.07
Shape, texture, and orientation encoding
Cards in this group · 5
- U1.07.1Shape is categorical only, and reliably distinguishable shapes are few
- U1.07.2Shape judgment needs adequate mark size; tiny scatter dots defeat it
- U1.07.3Texture fills are unstable under scaling and printing
- U1.07.4Orientation encodes a few ordered values but rotational symmetry confuses it
- U1.07.5Shape and texture differences survive greyscale output and colour-vision deficiency
