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.
