Raven’s Standard Progressive Matrices (SPM) test is widely regarded as the best psychological test of abstract or non-verbal reasoning ability (Lynn & al., 2004; Mackintosh, 1996, 1998). Many of research, bears on its validity (Gregory, 1992). It is a measure of general intelligence (Paul, 1985; Roccatagliata & Benassi, 1981).It was originally developed to assess the eductive ability(Bingham & al., 1966; JC Raven, 1940; J. Raven, 1989) , that is one of Spearman’s two components of “g” or general intelligence identiﬁed by Spearman (1923,1927). The figural analogies of SPM are designed regardless of language , culture and knowledge, depend only on current and on-line processing, are said to be tests of fluid intelligence (Burke, 1958; Raven & al., 2000). Furthermore, its is the best known and most widely used tests as measures of individual differences in cognitive ability (DeShon, & al., 1995; Powers & al., 1986), also sex differences (Lynn, 1999; Mackintosh & Bennett, 2005).
