Erik Thiessens research also sheds light on why adults may struggle to learn a second language
Adults may feel silly when they talk to babies, but those babies will learn to speak sooner if adults talk to them like infants instead of like other adults, according to a study by Carnegie Mellon University Psychology Professor Erik Thiessen published in the March issue of the journal Infancy.
Most adults speak to infants using so-called infant-directed speech: short, simple sentences coupled with higher pitch and exaggerated intonation. Researchers have long known that babies prefer to be spoken to in this manner. But Thiessens research has revealed that infant-directed speech also helps infants learn words more quickly than normal adult speech. In a series of experiments, he and his colleagues exposed 8-month-old infants to fluent speech made up of nonsense words. The researchers assessed whether, after listening to the fluent speech for less than two minutes, infants had been able to learn the words. The infants who were exposed to fluent speech with the exaggerated intonation contour characteristic of infant-directed speech learned to identify the words more quickly than infants who heard fluent speech spoken in a more monotone fashion.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
