During the study at Queen’s University, the researchers changed the vowel sounds that the participants heard over headphones as they talked. They found that while the adults and young children changed their vowel sounds in response to this altered feedback, the toddlers did not.
“We were very surprised to find that the two-year-olds do not monitor their own voice when speaking in the same way as adults do,” says Ewen MacDonald, a former Queen’s research associate and now associate professor at the Technical University of Denmark. "As they play music, violinists will listen to the notes they produce to ensure they are in tune. If they aren't, they will adjust the position of their fingers to bring the notes back in tune. When we speak, we do something very similar. We subconsciously listen to vowel and consonant sounds in our speech to ensure we are producing them correctly.”
The researchers have proven that toddlers use a different strategy to control speech than adults. They still have not pinpointed the exact method children under two use when learning to control speech. Future studies are being developed to determine what strategy toddlers are using.
“Understanding the development of speech is a complex and challenging problem. Using novel techniques, such as the ones used in this experiment, we can isolate and better understand how the different components of speech develop,” says Dr MacDonald. One possibility is that toddlers rely on the interaction with the person they are talking to in order to judge the accuracy of their speech sounds.
Other researchers on the study include Queen’s psychology professor Kevin Munhall and Elizabeth Johnson, an assistant professor in the department of psychology at the University of Toronto.
The research was recently published in Current Biology.

In living cells, enzymes drive biochemical metabolic processes enabling reactions to take place efficiently. It is this very ability which allows them to be used as catalysts in biotechnology, for example to create chemical products such as pharmaceutics. Researchers now identified an enzyme that, when illuminated with blue light, becomes catalytically active and initiates a reaction that was previously unknown in enzymatics. The study was published in "Nature Communications".
Enzymes: they are the central drivers for biochemical metabolic processes in every living cell, enabling reactions to take place efficiently. It is this very...
Early detection of tumors is extremely important in treating cancer. A new technique developed by researchers at the University of California, Davis offers a significant advance in using magnetic resonance imaging to pick out even very small tumors from normal tissue. The work is published May 25 in the journal Nature Nanotechnology.

Microelectronics as a key technology enables numerous innovations in the field of intelligent medical technology. The Fraunhofer Institute for Biomedical Engineering IBMT coordinates the BMBF cooperative project "I-call" realizing the first electronic system for ultrasound-based, safe and interference-resistant data transmission between implants in the human body.
When microelectronic systems are used for medical applications, they have to meet high requirements in terms of biocompatibility, reliability, energy...
Thomas Heine, Professor of Theoretical Chemistry at TU Dresden, together with his team, first predicted a topological 2D polymer in 2019. Only one year later, an international team led by Italian researchers was able to synthesize these materials and experimentally prove their topological properties. For the renowned journal Nature Materials, this was the occasion to invite Thomas Heine to a News and Views article, which was published this week. Under the title "Making 2D Topological Polymers a reality" Prof. Heine describes how his theory became a reality.
Ultrathin materials are extremely interesting as building blocks for next generation nano electronic devices, as it is much easier to make circuits and other...
Scientists took a leukocyte as the blueprint and developed a microrobot that has the size, shape and moving capabilities of a white blood cell. Simulating a blood vessel in a laboratory setting, they succeeded in magnetically navigating the ball-shaped microroller through this dynamic and dense environment. The drug-delivery vehicle withstood the simulated blood flow, pushing the developments in targeted drug delivery a step further: inside the body, there is no better access route to all tissues and organs than the circulatory system. A robot that could actually travel through this finely woven web would revolutionize the minimally-invasive treatment of illnesses.
A team of scientists from the Max Planck Institute for Intelligent Systems (MPI-IS) in Stuttgart invented a tiny microrobot that resembles a white blood cell...
