Sex differences and I.Q.

In a recent study that took place in Greece, 3000 subjects (aged 13–18) were used for the standardization of the AH4 by Heim. Various factors were examined, among them the relation between sex and I.Q. It was found that there are significant differences for Part I, Part II and Total AH4 in all ages except for the 14 and 15 year old groups.
