The WAIS – IV, the most current version of IQ testing and which replaced the WAIS-III in 2008, is the most current intelligence test and there are four index scores, two verbal and two performance, representing major components of intelligence.

Perceptual Reasoning Index measures one’s ability to use information gained through the senses, particularly visual and the ability to make sense of that information quickly, using them to make judgments about the world or act accordingly.
