Imaging study sheds light on neural origins of baby talk

11.08.2010
Neural processing in the brains of parents talking to their babies may reveal secrets about early stages of language acquisition in infants.

Neural processing in the brains of parents talking to their babies may reveal secrets about early stages of language acquisition in infants. This according to findings by researchers at the RIKEN Brain Science Institute and their collaborators, which show for the first time that experience, gender and personality affect how parents process the speech they use when addressing infants.

Infant-directed speech (IDS), also known as gbaby talkh, is a style of speech used by adults to address infants, characterized by high-pitched, articulated intonation and a simplified lexicon. While ubiquitous across languages and cultures, the neural mechanisms underlying IDS are unknown.

To elucidate these mechanisms, the researchers applied functional magnetic resonance imaging (fMRI) to the brains of 35 first-time parents with preverbal infants and 30 men and women without any parenting experience. Subjects also included 16 mothers with toddlers who spoke two-word utterances and 18 mothers with children in elementary school.

While initially aiming to measure brain activity during active speech, signal disruption caused by head movement prompted the researchers to focus on listening instead, which mirrors similar activation patterns without requiring any motion. Brain scans conducted on subjects listening to recorded IDS revealed that mothers with preverbal infants exhibited increased brain activity in areas of the brain known to govern language. This enhanced activation was not observed in any other group, including mothers of children who had advanced beyond the preverbal stage.

Another brain region signaled a second IDS connection: increased cortical activation was observed in speech-related motor areas of mothers in the same group who scored high on a personality test for extroversion. The results thus expose clear distinctions in how people process and generate IDS, providing the first evidence at the neural level that gbaby talkh, by acting as a bridge for linguistic transfer from mother to infant, plays a key role in the early stages of language acquisition.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
