Stronger early reading skills predict higher intelligence later

24.07.2014

A new study of identical twins has found that early reading skill might positively affect later intellectual abilities. The study, in the journal Child Development, was conducted by researchers at the University of Edinburgh and King's College London.

"Since reading is an ability that can be improved, our findings have implications for reading instruction," according to Stuart J. Ritchie, research fellow in psychology at the University of Edinburgh, who led the study. "Early remediation of reading problems might aid not only the growth of literacy, but also more general cognitive abilities that are of critical importance across the lifespan."

Researchers looked at 1,890 identical twins who were part of the Twins Early Development Study, an ongoing longitudinal study in the United Kingdom whose participants were representative of the population as a whole.

They examined scores from tests of reading and intelligence taken when the twins were 7, 9, 10, 12, and 16. Using a statistical model, they tested whether differences in reading ability between each pair of twins were linked to later differences in intelligence, taking into account earlier differences in intelligence.

Because each pair of identical twins shared all their genes as well as a home environment, any differences between them had to be because of experiences that the twins didn't share, such as a particularly effective teacher or a group of friends that encouraged reading.

The researchers found that earlier differences in reading between the twins were linked to later differences in intelligence. Reading was associated not only with measures of verbal intelligence (such as vocabulary tests) but with measures of nonverbal intelligence as well (such as reasoning tests).

The differences in reading that were linked to differences in later intelligence were present by age 7, which may indicate that even early reading skills affect intellectual development.

"If, as our results imply, reading causally influences intelligence, the implications for educators are clear," suggests Ritchie. "Children who don't receive enough assistance in learning to read may also be missing out on the important, intelligence-boosting properties of literacy."

Besides having implications for educational intervention, the study may address the question of why individual children from one family can score differently on intelligence tests, despite sharing genes, socioeconomic status, and the educational level and personality of parents with their siblings.

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
