(Pendel-Apparat für Komplikations-Versuche nach Wundt)
Description: This is like the original apparatus required for
Wundt's complication experiment. The "complication" experiment
required a subject to visually track the pointer moving across a
large dial. The subject had to take either a visual or auditory
set and respond to an auditory signal. When the subject had a
visual set, the reaction time was longer, and Wundt argued that
the task required a "voluntary" switching of attention. It was
criticized by Drobisch in 1864. (Expanded caption Copyright
