Zusammenfassung
This event-related brain potential (ERP) study aimed at bridging two hitherto widely independently evolved domains of cognitive neuroscience. Specifically, we combined the analysis of cognitive control in a task-switching paradigm with the fundamental question of how uncertainty is encoded in the brain. The metacognitive model of Nelson and Narens (1990) served as a start to this investigation. It led to the prediction that meta-level processes contribute to task control to the degree that decisions about task-sets are uncertain. Specifically, we predicted that P3a waveforms are evoked by events which eliminate…
