  2. *One participant with aMCI was not given the verbal component of the IQ estimate due to non-exclusionary English as a second language considerations. A comparable estimate of IQ was within the range exhibited by the remaining aMCI participants
  3. **Significance tests corrected for multiple comparisons using Bonferroni correction at p ≤ 0.05/7 (0.007)
