Words influence infants' cognition from first months of life

Northwestern University researchers have found that even before infants begin to speak, words play an important role in their cognition. For 3-month-old infants, words influence performance in a cognitive task in a way that goes beyond the influence of other kinds of sounds, including musical tones.

The research by Alissa Ferry, Susan Hespos and Sandra Waxman in the psychology department in the Weinberg College of Arts and Sciences, will appear in the March/April edition of the journal Child Development. In the study, infants who heard words provided evidence of categorization, while infants who heard tone sequences did not.

Three-month-old infants were shown a series of pictures of fish that were paired with words or beeps. Infants in the word group were told, for example, "Look at the toma!" –-- a made-up word for fish, as they viewed each picture. Other infants heard a series of beeps carefully matched to the labeling phrases for tone and duration. Then infants were shown a picture of a new fish and a dinosaur side-by-side as the researchers measured how long they looked at each picture. If the infants formed the category, they would look longer at one picture than the other.

The results, say the authors, were striking. The researchers found that although infants who heard in the word and tone groups saw exactly the same pictures for exactly the same amount of time, those who heard words formed the category fish; those who heard tones did not.

"For infants as young as three months of age, words exert a special influence that supports the ability to form a category," said Hespos, associate professor of psychology and one of the authors of the study. These findings offer the earliest evidence to date for a link between words and object categories."

Participants included 46 healthy, full-term infants, from 2 to 4 months of age. Half of the infants within each age bracket were randomly assigned to the word group. All infants in the language group were from families where English was the predominant language spoken in the home. The remaining infants were in the tone group.

"We suspect that human speech, and perhaps especially infant-directed speech, engenders in young infants a kind of attention to the surrounding objects that promotes categorization," said Waxman, a co-author and professor of psychology. "We proposed that over time, this general attentional effect would become more refined, as infants begin to cull individual words from fluent speech, to distinguish among individual words and kinds of words, and to map those words to meaning."

Im Focus: Attoseconds break into atomic interior

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.

In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...

Im Focus: Good vibrations feel the force

A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.

By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
