intelligent behavior to the user. In the research project ISReal, our research group developed the first platform for deploying virtual worlds based on Semantic Web technology, which enables agents to reason about and plan with semantically annotated 3D objects. Powerful tool support is required to design agents which exploit the functionality of the ISReal platform. We decided to reuse existing facilities

Studies investigating dual-task performance [Isreal et al., 1980] or retrieval of prospective memory (PM) [West 2011] gave insight into the capabilities of the brain to perform tasks in parallel and to switch between tasks [Bisiacchi et al., 2009]. However, most experiments are conducted under controlled conditions. Here, we investigate electroencephalographic (EEG) activity recorded under natural
