Children In Number Space

07.05.2008
In a paper recently published in Cortex, Jan Lonnemann (RWTH Aachen University, Germany) and colleagues report that many children at the age of 8-9 years seem to represent numbers spatially.

Interestingly, boys using this kind of representation tended to have better calculation abilities, while girls who represent numbers spatially tended to show poorer calculation abilities.

The authors assume that these differences may be due to gender-specific thinking styles: for boys, who may prefer visual-spatial thinking styles, it seems to be helpful to represent numbers spatially when being confronted with calculation problems, whereas for girls preferring verbal thinking styles it may be even detrimental.

Evidence for a connection between number and space processing comes from behavioural, patient, and brain imaging data, but only a few studies have addressed this issue in children. In this study, the Authors asked children (n=118) at the age of 8–9 years to decide which one of the two numerical distances in a visually presented number triplet was numerically larger. Numerical and spatial distances were manipulated independently, resulting in congruent, neutral, and incongruent conditions.

The spatial distances between the numbers clearly affected the comparison of numerical distances: reactions times were faster and error rates smaller for congruent than for incongruent trials. These findings are in line with the assumption of a spatial layout of mental number representations in third graders. Correlations between the size of the congruity effect and calculation abilities were found to be differently marked for girls and boys: a positive correlation was found for boys, while a marginally negative correlation was obtained for girls.

Im Focus: ScanCut project completed: laser cutting enables more intricate plug connector designs

Scientists at the Fraunhofer Institute for Laser Technology ILT have come up with a striking new addition to contact stamping technologies in the ERDF research project ScanCut. In collaboration with industry partners from North Rhine-Westphalia, the Aachen-based team of researchers developed a hybrid manufacturing process for the laser cutting of thin-walled metal strips. This new process makes it possible to fabricate even the tiniest details of contact parts in an eco-friendly, high-precision and efficient manner.

Plug connectors are tiny and, at first glance, unremarkable – yet modern vehicles would be unable to function without them. Several thousand plug connectors...

Im Focus: New Strategy Against Osteoporosis

An international research team has found a new approach that may be able to reduce bone loss in osteoporosis and maintain bone health.

Osteoporosis is the most common age-related bone disease which affects hundreds of millions of individuals worldwide. It is estimated that one in three women...

Im Focus: TU Graz Researchers synthesize nanoparticles tailored for special applications

“Core-shell” clusters pave the way for new efficient nanomaterials that make catalysts, magnetic and laser sensors or measuring devices for detecting electromagnetic radiation more efficient.

Whether in innovative high-tech materials, more powerful computer chips, pharmaceuticals or in the field of renewable energies, nanoparticles – smallest...

Im Focus: Tailored light inspired by nature

An international research team with Prof. Cornelia Denz from the Institute of Applied Physics at the University of Münster develop for the first time light fields using caustics that do not change during propagation. With the new method, the physicists cleverly exploit light structures that can be seen in rainbows or when light is transmitted through drinking glasses.

Modern applications as high resolution microsopy or micro- or nanoscale material processing require customized laser beams that do not change during...
