It’s common for people to pick up on each other’s movements. “This is the notion that when you’re having a conversation with somebody and you don’t care where your hands are, and the other person scratches their head, you scratch your head,” says Sasha Ondobaka of the Donders Institute for Brain, Cognition and Behaviour at Radboud University Nijmegen in the Netherlands.
He cowrote the paper with Floris P. de Lange, Michael Wiemers, and Harold Bekkering of Radboud and Roger D. Newman-Norlund of the University of South Carolina. This kind of mimicry is well-established, but Ondobaka and his colleagues suspected that what people mimic depends on their goals.
“If you and I both want to drink coffee, it would be good for me to synchronize my movement with yours,” Ondobaka says. “But if you’re going for a walk and I need coffee, it wouldn’t make sense to be coupled on this movement level.”
Ondobaka and his colleagues devised an experiment to see how much of a pull people feel to mimic when they have the same or different goals from someone else. Each participant sat across from an experimenter. They played a sort of card game on a touch screen embedded in the table between. First, two cards appeared in front of the experimenter, who chose either the higher or the lower card. Then two cards appeared in front of the participant. This happened 16 times in a row. For some 16-game series, the participant was told to do the same as the experimenter—to choose the higher (or lower) card. For others, they were told to do the opposite. Participants were told to move as quickly and as accurately as possible.
When the participant was supposed to make the same choice as the experimenter, they moved faster when they were also reaching in the same direction as the experimenter. But when they were told to do the opposite of the experimenter—when they had different goals—they didn’t go any faster when making the same movement as the other person. This means having different goals got in the way of the urge to mimic, Ondobaka says.
The researchers think that people only copy each other’s movements when they’re trying to accomplish the same thing. The rest of the time, actions are more related to your internal goals. “We’re not walking around like chameleons copying everything,” Ondobaka says. If you’re on a busy street with dozens of people in view, you’re not copying everything everybody does—just the ones that have the same goal as you. “If a colleague or a friend is going with you, you will cross the street together.”

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
