Zusammenfassung:	Every human behavior bears the potential for a mistake. Sometimes it is hard to make the right decision. Sometimes it is difficult to perform an action correctly. Our everyday life involves a constant risk of performing a behavior more or less incorrectly, leading to negative consequences of varying severity. To err is human, but so is learning from our actions. In the course of evolution, humans have developed a complex neural system to detect errors, resolve cognitive conflict and adapt future behavior. As multifaceted the range of situations and behaviors we encounter in everyday life is, so are the neuroscientific studies and findings on this performance monitoring system. Therefore, this dissertation aims to integrate different approaches to investigate performance monitoring with a particular focus on a neural indicator that consistently appears in the literature on performance monitoring research, namely frontomedial theta activity (FMT). In a series of four studies, FMT activity in the scalp-recorded electroencephalogram (EEG) was examined in different situations and settings, applying different analysis procedures and considering interpersonal differences and intraindividual temporal stability. Study 1 investigated fine-grained additive effects of FMT activity in response to multiple independent outcomes in a non-dynamic laboratory setting and their stability over time. In contrast to the distinctive feedback presentation in study 1, study 2 investigated the effects of continuously incoming information during the performance monitoring process in a dynamic shooting task within virtual reality. As in a wide variety of daily actions, this design allowed for the anticipation of an outcome before it occurs and thus “online” performance monitoring. Study 3 advances the dynamics of the setting even further by implementing a shooting task without virtual reality but in a Mobile Brain/Body Imaging (MoBI) setting (Makeig et al., 2009), using toy guns with foam darts to shoot a stationary target. This study investigated the characteristics of the oscillatory phase of the measured FMT signal. Study 4 investigated FMT activity in response to cognitive conflict rather than negative action outcomes. Using source separation analyses, individual sensitivities to different kinds of conflict are investigated to determine whether FMT has the same or different neural sources across different contexts. The four studies are discussed to determine the functional role of FMT in performance monitoring and whether FMT may reflect a unitary signal for performance monitoring across diverse contexts and tasks.
