But actually, being able to change intonation in speech – as in upspeak – may be a sign of superior empathy?
A new study in the journal PLoS ONE finds that people use the same brain regions to produce and understand intonation in speech.
Many studies suggest that people learn by imitating through so-called mirror neurons. This study shows for the first time that prosody – the music of speech – also works on a mirror-like system.
And it turns out that the higher a person scores on standard tests of empathy, the more activity they have in their prosody-producing areas of the brain.
So increased empathic ability is linked to the ability to perceive prosody as well as activity in these motor regions, said authors Lisa Aziz-Zadeh and Tong Sheng of USC, and Anahita Gheytanchi of the Pacific Graduate School of Psychology.
“Prosody is one of the main ways that we communicate with each other,” Aziz-Zadeh said.
In some cases, humans can’t do without it, as in the case of a stroke victim who garbles words but can express emotion.
Or when talking to a pet: “If you have a pet, they basically are understanding your prosody,” Aziz-Zadeh said.
She and her colleagues imaged the brains of 20 volunteers as they heard and produced prosody through happy, sad and other intonations of the nonsensical phrase “da da da da da.”
The same part of the brain lit up when the volunteers heard the phrase as when they repeated it. It is called Broca’s Area and sits about two inches above and forward of each ear.
The volunteers with the most activity in Broca’s Area tended to score high on empathy measures. They also used prosody more frequently in daily speech.
It is not clear whether empathy brings about prosodic activity or whether frequent use of prosody can somehow help to develop empathy – or whether there is no cause and effect relationship either way.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
