Raven’s Advanced Progressive Matrices item taxonomies

There are classifications gallore.  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.
