Discriminant Validity of Non-Verbal Memory Test. During the 'learning phase' of the Mindstreams Non-Verbal Memory test, four consecutive repetitions of a recognition test were administered. In (A), mean accuracy is shown across repetitions for cognitively healthy elderly (diamonds), mild cognitive impairment (MCI; squares), and mild Alzheimer's disease (AD; triangles) participants. (B) depicts mean performance (+ standard error) for each of the diagnostic groups on the final repetition trial. MCI participants are discriminable from healthy elderly and from those with mild AD (see Table 4).
