High-status monkeys ignore the interests of riff-raff

22.02.2006


Where we look often reveals our interests and intentions. Consequently, we often look toward others and follow their gaze to the objects to which they give visual attention. Like humans, monkeys pay attention to the eyes of individuals within their groups; in the laboratory, they respond more quickly to a target when they have seen another individual look at it. Researchers at Duke University Medical Center now demonstrate that social status strongly determines how monkeys deploy their attention to others: high-status monkeys are slower and more selective about whose gaze they follow than are low-status monkeys.



In the current study, Stephen Shepherd, Robert Deaner, and Michael Platt examined the time course of attention when male macaques saw other high- or low-status male macaques looking toward or away from a target. They found that low-status monkeys shifted attention to the target within a tenth of a second after seeing another monkey do so. High-status monkeys, however, were half as fast and only followed the gaze of other dominant monkeys.

The findings indicate that gaze-following in monkeys is composed of both reflexive and voluntary elements, and they also demonstrate that social status of an individual gates that individual’s deployment of social attention. The study results further suggest that biological correlates of high social status, such as elevated levels of the male sex hormone testosterone, may suppress so-called "social vigilance," which is high in low-status males that readily follow the gaze of others.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

Im Focus: Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
