Cognitive and Biological Psychology

Lab

In our lab (hard- and software, cf. ), we can create auditory and visual stimuli to be run in real-time under a wide variety of experimental protocols. With our dummy head we can record natural sounds and measure sound pressure level. We can perform audiometrics, register behavioral and multi-channel EEG data, electrodermal and cardiovascular activity. With this, we address questions in auditory and visual information processing, (working) memory, learning, attention and emotion, and the predictive nature of the human information processing system (cf. research).
