When you see a small child try to fit into or on top of a doll-sized toy, youre likely to laugh. Thats exactly what three co-investigators of a new study initially did when their own toddlers attempted to fit into a toy car, a miniature room and a dolls crib.
Based on those personal observations, as well as their research as developmental psychologists interested in how young children understand symbols, the researchers from the University of Virginia, Northwestern University and the University of Illinois at Urbana-Champaign set out to understand why youngsters, who actually know better, make such dramatic mistakes about scale.
Not to worry, moms and dads. The study of 18- to 30-month-old children, published in the May 14 journal Science, found these kinds of errors -- scale errors -- to be common in this age group. Videotapes show many participants in the research seriously trying to slide down miniature slides, squeeze into tiny toy cars and sit in dollhouse chairs.

Innsbruck quantum physicists have constructed a diode for magnetic fields and then tested it in the laboratory. The device, developed by the research groups led by the theorist Oriol Romero-Isart and the experimental physicist Gerhard Kirchmair, could open up a number of new applications.
Electric diodes are essential electronic components that conduct electricity in one direction but prevent conduction in the opposite one. They are found at the...
Max Planck researchers revel the nano-structure of molecular trains and the reason for smooth transport in cellular antennas.
Moving around, sensing the extracellular environment, and signaling to other cells are important for a cell to function properly. Responsible for those tasks...
Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
