Sound to touch

A team of researchers led by Marcus Jeschke at the German Primate Center – Leibniz Institute for Primate Research (DPZ) and at the Institute for Auditory Neuroscience led by MBExC member Tobias Moser at the University Medical Center has developed an automated auditory training program that marmoset monkeys can perform in their familiar environment on a voluntary basis. The team has accomplished getting non-human primates to complete a series of tests in which they hear different sounds and then match them to the appropriate, previously learned visual stimuli by clicking on a touchscreen. This allows scientists to track which sounds the animals can hear and discriminate. The monkeys themselves decide whether, when and for how long they participate in a hearing test.
