“…Mackintosh and Bennett's (2005) results are consistent with a number of dimensionality studies of Raven's Matrices Intelligence 36 (2008) reporting multifactorial solutions. Most of these studies pertained to the Standard version of the Matrices (SPM, Raven, 1956;e.g., Lynn, Allik & Irwing, 2004;van der Ven & Ellis, 2000), but there have been reports indicating that the advanced version of the Matrices (APM) could also be multidimensional (Dillon, Pohlmann & Lohman, 1981). The notion that Raven's Matrices items can be classified in terms of the information processing rules required for their solution was most notably developed by Carpenter et al (1990).…”
