English: "a, b Group-average g-factor (30 groups, based on g-factor, N = 650 subjects) versus RT for correct responses in PMAT questions #1 (very easy, p=4.0×10−6) and #24 (very hard, p=3.0×10−6). c, d Group-average and subject-level correlations between g/PMAT24_A_CR and the RT for correct responses in each individual PMAT question. Subjects with higher g/PMAT24_A_CR were quicker to correctly answer easy questions, but they took more time to correctly answer hard questions (questions sorted according to increasing difficulty; sign of correlation flips at question #9). e Group-average g-factor versus mean FC (20 groups, based on g-factor, N = 650 subjects, p=0.13). f Group-average PMAT24_A_RTCR versus mean FC (20 groups, based on PMAT24_A_RTCR, N = 650 subjects, p=6.9×10−7). g, h Group-average (20 groups, based on PMAT24_A_RTCR) and subject-level correlations between mean FC and RT for correct responses in each PMAT question. Subjects that took more time to correctly answer test questions had a higher FC, independent of whether the question was easy or hard. P values of two-sided Pearson’s correlation test: *p < 0.05, **p < 0.01, ***p < 0.001; including only p values that remained significant after controlling for multiple comparisons using the Benjamini–Hochberg procedure with a False Discovery Rate of 0.1."
