| Beschreibungen: | The posterior medial frontal cortex (mPFC) is a major contributor to action monitoring. In response-locked electroencephalography (EEG), two frontocentral event-related components (ERPs) with presumed origins in medial prefrontal cortex (mPFC) are associated with action monitoring: the error-related negativity (ERN) peaking 80-100 ms after error commission, and an observer mediofrontal negativity (oMN) peaking 100-300 ms after error observation. The predicted outcome-response (PRO) model and empirical findings suggest that the mPFC represents not action valence but expectancy violations. Observed action
monitoring processes are probably further modulated by empathy, and possibly in relation with expectancies. Effects of subjective and objective error significance on action monitoring ERP components challenge the PRO model as they cannot be explained by expectancies. This PhD project aimed to investigate effects of expectancies, empathy and error severity as potential modulators of observed action processing. Studies 1 and 2 used a false-belief paradigm to differentiate valence and expectancy effects on observed action monitoring and its modulation by empathy. Study 1 showed that an early observed action monitoring component resembling the oMN represents expectancies, not vicarious error processing, and the results suggested an indirect effect of empathy on ERP amplitudes. This was confirmed in study 2 by showing that single-trial expectancy values influenced ERP amplitudes of a later ERP component, and were themselves influenced by empathy. Empathy could not explain additional variance of the ERP component. In study 3, we found (contrary to the PRO model) that error severity modulated the ERN in a piano playing paradigm. However, we found no error severity, but a binary valence effect for the oMN, which might be explained by expectancies. Expanding the PRO model, we suspect that the mPFC sends a need-to-adapt signal if either actions or predictions need to be adapted. Depending on the task, the focus might be either on predictions (studies 1 and 2) or actions (active paradigm in study 3). Future studies might investigate this theory by manipulating action and prediction deviations and the task focus.The posterior medial frontal cortex (mPFC) is a major contributor to action monitoring.
