Test the interaction of the CS and frustrative non-reward as part of the NVS. It
will investigate the electrophysiological correlates of frustrative feedback in
aggression-prone patients. In the aftermath of induced stress, an EEG task-
battery including frustrative feedback will be applied for extraction of error-
related negativity (ERN) and contingent negative variation to monitor electro-
physiologic signaling of the relevant learning and frustration processes. In
half of the participants, tDCS over the prefrontal cortex will be applied to
enhance cognitive control, with participants being put into a stress context
inducing frustration.
Objective:: Cortisol is a well-established biomarker of stress, assessed through salivary or blood samples, which are intrusive and time-consuming. Speech, influenced by physiological stress responses, offers a promising non-invasive, real-time alternative for stress detection. This study examined relationships between speech features, state anger, and salivary cortisol using a validated stress-induction paradigm.
