Not really, it varies per test. (Such norms and info is what professional psychologists & psychometricians are paying for when they pay through the nose for IQ tests.)
My general impression from looking at before-afters for the RAPM/BOMAT-using dual n-back studies was that the controls would improve on average something like half a question, which would translate to maybe 2 or 3 points?
Hmm. I got 138 yesterday, and I’m pretty sure the 120 I remember entering in last year’s survey was from that same online test. Wondering what’ s up with that.
