Memory performance in the recognition task and associations with hippocampal and amygdala volumes.
(A) Mean accuracy and RT in the face-location memory task. Vertical lines on the bars refer to mean standard error. Asterisks indicate significant differences between the two conditions of congruency and between the aMCI-c group and the remaining two groups. (B) Scatter plots depicting correlation between residuals of associative d’ and residuals of hippocampal or amygdala volume either on the left or right hemisphere after regressing these variables on age and total ICV. Each color represents one group. Given that regressions only reached significance when all participants were included in the analysis, only one fitted regression line was shown for each scatter plot.
