Vagally-mediated HRV predicting ESST performance
In order to replicate our previous findings, which suggest a significant effect of resting vmHRV, vmHRV reactivity as well as the interaction between both on ESST performance, we performed two linear regressions (for the pre and the post-stimulation ESST, respectively) in R Studio (R Core Team, 2022). To test whether resting vmHRV and vmHRV reactivity predict SSRT, resting RMSSD, the RMSSD reactivity score, as well as the interaction between both values were entered as predictors. Potential confounders, namely mean reaction time on go-trials, age, and sex were included as covariates.
