I am confused about PG vs. high performance kids and the intersection of the two. I always thought, that PG kids would squarely fall inside the high performance bucket and so we thought our DS is not one of them. It seems that we have a PG kid if his score is an indicator, his FSIQ says he is just normally gifted (wide discrepancy between VS score and other scores, the rest are in the gifted range but not that kind of standard deviation), but Psychologist said that his GAI is a low estimate because he hit the VS ceiling for WISC V and WAIS and there was no extended norm to consult for his scoring..
One of the factors to consider is that until recently, the most commonly-used cognitive assessment instruments did not assess visual spatial ability separately from abstract-fluid reasoning. This was not really by chance. VS is the least K-12 school-relevant of the three cognitive areas usually assessed (verbal, quantitative/abstract, visual spatial), although, of course, it has a great deal of value in life, as well as much later in schooling. A quick scan of the literature finds quite a bit of overlap among discussions of/research on visual spatial learners, divergent thinkers, and those with learning differences/disabilities (dyslexia and ADHD, most commonly).
This is not to say that all VS-high learners are 2e, necessarily, but that school is designed for and by verbal (and quantitative) learners (not to mention compliance-high). Consequently, VS-high learners may not have latitude to display their greatest strengths in the school setting, and may perform only at the level of their verbal/quantitative abilities. As long as you continue to feed the strength areas outside of school, and your child is happy and growing in all cognitive, emotional, social, spiritual, etc. dimensions, that's fine. I think some VS-high children find community/peer-recognized channels in the fine and performing arts, robotics or anime clubs, VS-high games with social capital, like Minecraft, or sometimes in sports.
One could also specify the area of giftedness, to avoid some of the cultural accretions that come with the label of global PG-ness. E.g., PG in visual spatial ability (possibly in the context of global MG). Much like one might describe an individual as an exceptional athlete, talented entrepreneur, or unusually empathetic friend.
