The basic economic theory that people work harder to avoid losing money than they do to make money is shared by monkeys, suggesting this trait has a long evolutionary history, according to a Yale University study under review by the Journal of Political Economy.
This phenomenon, known as "loss aversion," refers to the tendency for people to strongly prefer avoiding losses to acquiring gains. "A large body of studies suggest that losses are more than twice as psychologically powerful as gains," said author M. Keith Chen, assistant professor at Yale School of Management.
In this study conducted with Venkat Lakshminaryanan, a research assistant in the Department of Psychology, and Laurie Santos, assistant psychology professor and director of the Capuchin Cognition Laboratory at Yale, tufted capuchin monkeys were given small disks to trade for rewards--apples, grapes or gelatin cubes. The researchers said capuchins are well-suited subjects for study since they are relatively large-brained primates, skilled problem solvers, and a close evolutionary neighbor to humans.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
