The WISC-IV is the most popular psychological battery in the world. However, not all subtests remain the same in the various adaptations of the scale. In fact, only the subtests included in the perceptual reasoning and in the processing speed indexes remain virtually the same across various adaptations of the scale. In this paper we compared Italian with United Kingdom norms in these two indices. Results showed that differences in the processing speed index were small and that they were larger in the perceptual reasoning index. Further, differences between the two standardizations, were not homogeneous, but concentrated in specific age groups. The clinical and theoretical implications of the study will be discussed.
