*p-value is significant at Bonferroni-corrected value of .017; Each regression included age, gender, and education as covariates. NovelvsR2 C1 = Level of activation in Cluster 1 for the novel vs. repeated twice conditions; β = Beta; R²= R squared; df = degrees of freedom; NovelvsR2 C3 = Level of activation in Cluster 3 for the novel vs. repeated twice conditions; NovelvsR2 C4 = Level of activation in Cluster 4 for the novel vs. repeated twice conditions; C1xDiagnosis = Interaction term which was generated by multiplying activation in Cluster 1 and diagnosis coded as −.5 for the mild cognitive impairment group and .5 for the healthy control group; C3xDiagnosis = Interaction term which was generated by multiplying activation in Cluster 3 and diagnosis coded as −.5 for the mild cognitive impairment group and .5 for the healthy control group; C4xDiagnosis = Interaction term which was generated by multiplying activation in Cluster 4 and diagnosis coded as −.5 for the mild cognitive impairment group and .5 for the healthy control group.
