Fig. 4 — a Left, student and class patterns are correlated on a question-by-question basis to derive alignment-to-class during exam. Right, student and expert patterns are similarly correlated to derive alignment-to-experts. b Within-subject correlation between alignment and exam score in a single ROI, in a single student. Violet dots represent individual exam questions. Left, correlation between alignment-to-class and exam score. Right, correlation between alignment-to-experts and exam score. c Within-subject correlation between alignment and exam score in a single ROI, trendlines for all students shown. Red, the trendline of the student shown in panel b. Black, mean across all students. Left, correlation between alignment-to-class and exam score. Right, correlation between alignment-to-experts and exam score. Asterisks denote significant correlation (one-sided permutation test, corrected), *p < 0.05, **p < 0.01. For all ROI analysis results, see Table 2. d Correlation across the cortex, searchlight analysis results shown. Voxels showing significant correlation are shown in color (one-sided permutation test, p < 0.05, corrected). Left, correlation between alignment-to-class and exam score. Right, correlation between alignment-to-experts and exam score. Control analyses for response length are shown in Supplementary Fig. 2a and 2b. Note the correspondence between the two maps in major DMN nodes on the medial surface. LH left hemisphere, RH right hemisphere, Ant. anterior, Post. posterior.
