High-arousal vocalizations are understood by both humans and other species in the animal kingdom, study says — LiveScience.Tech

Exists something universal about the sounds we make that enables singing students — like songbirds — to find out how we’re feeling? Seems like it, according to brand-new research study by University of Alberta researchers.

The scientists analyzed the components within vocalizations that show a level of stimulation such as worry or enjoyment. They discovered that both humans and black-capped chickadees can find arousal levels in other species.

“The idea is that some species can understand other species’ vocalizations,” described Jenna Congdon, PhD trainee in the Department of Psychology. “For instance, a songbird is able to understand the call of distress of a different type of songbird when they are in the presence of a predator, like an owl or a hawk. Or, for example, if your friend scared you and you screamed. Both of these are high-arousal vocalizations, and being able to understand what that sounds like in a different species can be very useful.”

Under the guidance of Teacher Chris Sturdy, Congdon carried out 2 experiments, one taking a look at chickadees and another taking a look at humans. In the experiments, individuals compared high- and low-arousal vocalizations produced by other species, consisting of alligators, chickadees, elephants, humans, pandas, piglets, ravens, macaques, and tree frogs. Human topics had the ability to determine high stimulation in various species.

“Black-capped chickadees were also able to identify high arousal in other chickadees, humans, and giant pandas,” stated Congdon. “This is fascinating, because a chickadee that has never come across a giant panda before is able to categorize high — and low — arousal vocalizations.”

The researchers presume that other singing students, or species that discover their vocalizations from moms and dads and designs in order to endure, have this capability also. “It is only a small group of species who do this in the world — humans, songbirds, hummingbirds, parrots, bats, whales and dolphins, and elephants,” stated Congdon. “If humans and songbirds show an innate ability to understand the vocalizations of other species, would other vocal learners show this same propensity?”
