Side Event: Saturday, 8 November

As a side event, we offer an excursion to the Wilhelm Wundt Collection at University of Leipzig. The room contains original devices, manuscripts and other artefacts from the father of experimental psychology and his laboratory. The guided tour will be given by Robert P. O’Shea (Professor for History of Psychology) in English and should last for approximately one hour. Note that for this side event we will unfortunately not be able to offer interpreting into International Sign (IS)! However, English ⇄ German Sign Language (DGS) interpreting will be available.

Prior registration is required (e-mail Patrick at trettenbrein@cbs.mpg.de). Regardless of whether you are a presenter at the workshop or have registered as a non-presenting participant, you have to register again to join the excursion! The maximum number of participants is 20. Spots are allocated on a first-come-first-serve basis.

We will meet in front of the workshop venue in Stephanstraße 1a, 04103 Leipzig on Saturday, 8 November at 10:00 and jointly walk to the university building in the city centre (about 10 mins. walk). Alternatively, you can join us directly at the Wilhelm Wundt Institute of Psychology at Städtisches Kaufhaus, Neumarkt 9, 04109 Leipzig at 10:30 sharp.
