That being said, a common personality trait among gifted students is a need for precision and accuracy. As a result, they will develop slow, meticulous responses to any given mental task. This personality trait will have the tendency to decrease his or her processing speed, and a common profile among gifted people of all ages is high verbal comprehension, perceptual reasoning, and working memory indices, accompanied with a relatively low processing speed index. However, it should be noted that this personality trait also has the tendency to inflate the other three indices on the Wechsler Battery, and so the full-scale IQ is still reliably measured by the test

Not true at all for PRI at least. The 'blocks section' of the WISC IV is timed and I could see (via double mirror) my DD basically playing and exploring the potential of the blocks as well as checking and rechecking (perfectionism). While she solved every block task, she took her own time about it so only got credit for what she did within the time which held her PRI down to 145.
