The study, appearing in an upcoming issue of the journal Psychonomic Bulletin & Review, is the first to show that a person’s ability to solve a problem can be influenced by how he or she moves.
“Our manipulation is changing the way people think,” said University of Illinois psychology professor Alejandro Lleras, who conducted the study with Vanderbilt University postdoctoral researcher Laura Thomas, his former graduate student. “In other words, by directing the way people move their bodies, we are – unbeknownst to them – directing the way they think about the problem.”
Even after successfully solving the problem, almost none of the study subjects became consciously aware of any connection between the physical activity they engaged in and the solution they found.
“The results are interesting both because body motion can affect higher order thought, the complex thinking needed to solve complicated problems, and because this effect occurs even when someone else is directing the movements of the person trying to solve the problem,” Lleras said.
The new findings offer new insight into what researchers call “embodied cognition,” which describes the link between body and mind, Lleras said.
“People tend to think that their mind lives in their brain, dealing in conceptual abstractions, very much disconnected from the body,” he said. “This emerging research is fascinating because it is demonstrating how your body is a part of your mind in a powerful way. The way you think is affected by your body and, in fact, we can use our bodies to help us think.”
In the study, the researchers asked study subjects to tie the ends of two strings together. The strings dangled from ceiling rafters and were so far apart that a person grasping one could not reach the other. A few tools were also available: a paperback book, a wrench, two small dumbbells and a plate. Subjects were given a total of eight, two-minute sessions to solve the problem, with 100 seconds devoted to finding a solution, interrupted by 20 seconds of exercise.
“Our cover story was that we were interested in the effects of exercise on problem-solving,” Lleras said.
Some subjects were told to swing their arms forward and backward during the exercise sessions, while others were directed to alternately stretch one arm, and then the other, to the side. To prevent them from consciously connecting these activities to the problem of the strings, the researchers had them count backwards by threes while exercising.
The subjects in the arm-swinging group were more likely than those in the stretch group to solve the problem, which required attaching an object to one of the strings and swinging it so that it could be grasped while also holding the other string. By the end of the 16-minute deadline, participants in the arm-swinging group were 40 percent more likely than those in the stretch group to solve the problem.
“By making you swing your arms in a particular way, we’re activating a part of your brain that deals with swinging motions,” Lleras said. “That sort of activity in your brain then unconsciously leads you to think about that type of motion when you’re trying to solve the problem.”
Previous studies of embodied cognition have demonstrated that physical movements can aid in learning and memory or can change a person’s perceptions or attitudes toward information, Lleras said.
Other studies by Lleras and his colleagues also have shown that directing a person’s eye movements or attention in specific patterns can also aid in solving complex problems, but this is the first study to show that directed movements of the body can, outside of conscious awareness, guide higher-order cognitive processing, he said.
“We view this as a really important new window into understanding the complexity of human thought,” he said. “I guess another take-home message is this: If you are stuck trying to solve a problem, take a break. Go do something else. This will ensure that the next time you think about that problem you will literally approach it with a different mind. And that may help!”

Neuromuscular organoid: It’s contracting!

Styrofoam or copper - both materials have very different properties with regard to their ability to conduct heat. Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz and the University of Bayreuth have now jointly developed and characterized a novel, extremely thin and transparent material that has different thermal conduction properties depending on the direction. While it can conduct heat extremely well in one direction, it shows good thermal insulation in the other direction.
Thermal insulation and thermal conduction play a crucial role in our everyday lives - from computer processors, where it is important to dissipate heat as...
In order to advance the transfer of research developments from the field of quantum sensor technology into industrial applications, an application laboratory is being established at Fraunhofer IAF. This will enable interested companies and especially regional SMEs and start-ups to evaluate the innovation potential of quantum sensors for their specific requirements. Both the state of Baden-Württemberg and the Fraunhofer-Gesellschaft are supporting the four-year project with one million euros each.
The application laboratory is being set up as part of the Fraunhofer lighthouse project »QMag«, short for quantum magnetometry. In this project, researchers...

Researchers from the University Hospital Zurich, ETH Zurich, Wyss Zurich and the University of Zurich have developed a machine that repairs injured human livers and keep them alive outside the body for one week. This breakthrough may increase the number of available organs for transplantation saving many lives of patients with severe liver diseases or cancer.
Until now, livers could be stored safely outside the body for only a few hours. With the novel perfusion technology, livers - and even injured livers - can now...
A balloon-borne scientific instrument designed to study the origin of cosmic rays is taking its second turn high above the continent of Antarctica three and a half weeks after its launch.
SuperTIGER (Super Trans-Iron Galactic Element Recorder) is designed to measure the rare, heavy elements in cosmic rays that hold clues about their origins...
