My question regarding FS vs GAI and WM/PSI is how low is low? On this board we're talking about differences between WM/PSI and VCI/PRI where VCI/PRI are very, very high. At one site I read, it was noted that the WM/PSI is really for indicating educational success at the lower end of the spectrum. For ex: a 20 pt difference w/ avg VCI/PRI and even lower PSI/WM affects a child greatly in the classroom. So would a >20pt difference putting PSI/WMI in the avg range and VCI/PRI in the 140s, have an adverse affect on an HG+ kid? The report I read suggested not. But if you do you have more info and more complex info in your head compared to age-mates, would an avg PSI/WMI have an affect on performance?
