Some people are annoyed by upspeak: the habit of making a sentence sound like a question?
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.

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
