Raven’s Advanced Progressive Matrices item taxonomies

There are classifications galore.  Below is a comparison of one by DeShon, Chan, and Weissbein (1995) with one by Styles (2008):

DeShon et al
Styles ? Analytic Both Either Visual
? 1 0 0 0 0
D/T 0 1 0 0 0
Distribution 0 2 0 0 0
Equation 0 1 3 0 8
S/D 0 1 0 0 0
S/D/T 0 3 1 0 0
S/T 0 0 0 0 1
Seriation 0 1 2 4 3
Transformation 0 3 0 0 1

Pretty good agreement between DeShon and co’s “visuospatial” and Styles’ “equation” (both what does and doesn’t fall into these buckets).  The “equation” items concern those with “overlapping elements” – seems pretty visuospatial.  Also neither classification codes item 15: DeShon and co say it violates the task instructions.  The rest is a bit of a mess, but then Styles peeked at a higher resolution into the analytic items.
