| Abstract: | Relative frontal asymmetry (RFA) has previously been outlined as an index of emotional regulation and valence and was recently linked to the human stress response. Zhang et al. (2018) found RFA at rest to be predictive of the cortisol response after being subjected to a bilateral feet Cold Pressor Test (CPT) and observed functional changes in RFA during the CPT. The current study tried to replicate these results following the same methodology in both a larger sample based on the same inclusion criteria as the original study and a second sample including female subjects. Although the stress induction was successful in both samples shown by increases of cortisol, heart rate, blood pressure and ratings of stress and arousal absent in the control condition, no state-dependent shift of RFA during stress induction was observed in either sample. The current study confirmed the relation between RFA at rest and cortisol, however the observed response pattern differed from the original study as RFA both pre-, and post-stress was significantly correlated to cortisol. However, the correlation with cortisol was only significant for the exclusively male sample. In general, sex only presented a significant factor in regard to the stress parameters and not in relation to RFA, yet this might also be attributable to the overall absence of state-dependent changes in RFA in the present study. |
