Multitasking different jobs is no problem, but double talk overwhelms us

27.09.2006
We can listen to a car radio and drive while keeping an eye on changing traffic conditions -- separate complex tasks completed without much trouble. But if two people are talking to us at the same time, our perceptual frequencies get jammed.

A new Cornell study shows that people are pretty good at perceptual multitasking -- except when multiple sources of incoming stimuli are of the same type. Morten Christiansen, associate professor of psychology, co-authored the study with Christopher Conway, a National Institutes of Health research fellow at Indiana University.

Humans learn "sequential structure from multiple sources at the same time, as long as the sensory characteristics of the sources do not overlap," Christiansen said.

Participants in the study experienced little difficulty learning complex structures streamed at them simultaneously, such as tones and colors or even tones and speech.

"However, performance dropped when the two sets of sequences were from the same perceptual class of stimuli, such as two sets of speech stimuli," said Conway. "Overall, these results show that humans have a powerful learning system that is capable of learning sequential patterns simultaneously from multiple environmental sources -- provided each source is perceived as being distinct."

The study will appear in Psychological Science in October.

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...

Im Focus: The proton precisely weighted

What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.

To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
