Linear regression of the long-term memory and difference between monomodal and bimodal coherence (ΔC) when investigating the effect of different time windows while controlling for sociodemographic factors, such as birth measures, years of education, and neurocognitive tests for speed of processing and attention as in Table 2. In Panel A we investigate the mono-to-bimodal coherence differences in the anterior part of the brain. In Panel B we investigate the mono-to-bimodal coherence differences in the total brain. Each column represents one linear regression model. Adding control variables, we find that the coefficient on coherence was robust enough to account for these factors. Columns 2 and 4 were adjusted for bio-social factors (i.e., birth measures and years of education), each of the three cognitive test measures of speed of processing and visual attention, as well as the intelligence score (i.e., I-S-T-2000-R) and working memory using the 15-word pair learning score. The semi-partial R2 for the main explanatory variables are shown along the total adjusted R2.
