Zoo monkeys connect to the Amazon-style media system to see if they prefer music or videos
The ZOO monkeys connected to an Amazon Primate media system to see if they prefer music or videos.
They even toggled between three choices by triggering infrared sensors.
The researchers placed the “player” in a tunnel in an enclosure for three white-faced saki.
On some days, areas would have videos – worms, underwater scenes and abstract shapes to choose from by triggering the sensor.
The videos would turn off if the monkeys lost interest, usually after a few seconds.
On other days there were three sound bites – electronic music plus traffic and rain sounds.
Experts found saki opted slightly more for audio content, but not enough to say it was their preference.
Dr Ilyena Hirskyj-Douglas from the University of Glasgow, who led the research at a zoo in Finland, said: “We have already explored how monkeys interact with video content and audio content, but that is the first time we give the possibility to choose between the two.
“Our results raise a number of questions that deserve further study to help us build effective interactive systems.”
