Today, in the 21st ScienceBeer, Friederike was our Science Brewer. Friederike is a PhD in TU-Dresden and works on Psychology. Friederike made an impressive investigation about the interrogation sessions and in this ScienceBeer she shared her experience about the procedure of interrogations in Dresden police department with us. Have you ever thought about the loss of emotional semantics when you read a sentence on a paper rather than hearing it on a tape? or watching a video of the speaker's face? But did you also consider that you may miss some important oral information because you are focusing too much on the visuals? Friederike answered all of these questions. Thank you Friederike.
