❓ FAQ
Do I need to be good at maths?The sums are small. The point is storage while deciding, not a maths contest or an IQ. 練習であり臨床IQではない。
What if I miss a true/false?You still try to recall the letters. Labs sometimes drop inaccurate processing trials. We still count letter hits as a toy. 練習であり臨床IQではない。
Is this dual n-back?No. OSPAN-style is processing plus serial recall. Dual n-back is updating two streams. 練習であり臨床IQではない。
