“…It has been stated that the type of university education (science or arts) does not moderate the differences according to sex (Contreras, Colom, Shih, Alava, & Santacreu, 2001); that even though Voyer et al (1995) suggested that procedural differences are an important source of variance in the magnitude of sex differences, males still have an advantage when these performance factors are partialed out (Contreras, Rubio, Peña, Colom, & Santacreu, 2007). Other studies inform that the solution strategies of a task determine performance in a dynamic spatial task more so than other performance variables but, even in this case, sex differences remain significant (Peña, Contreras, Shih, & Santacreu, 2008;Sacuzzo, Craig, Johnson, & Larson, 1996;Schiff & Oldak, 1990).…”
