  1. CFMT+ long form of the Cambridge Face Memory Test, MMT models memory test, PMT pairs matching test, SD standard deviation
  2. aRaw score cut-off values rounded up to the next whole number that is 1.96 SDs from the control mean. This score is taken as the cut-off value to determine superior performance. Note that cut-off values were calculated prior to rounding
