Note: MCI = mild cognitive impairment, p value = significance of chi-square tests between observed distribution and expected distribution based on the normal curve distribution of z scores (5% display smaller-than-expected practice effects, 90% display expected practice effects, 5% display greater-than-expected practice effects).
