An international team of researchers looked at the role of personality by studying 298 gorillas in North American zoos and sanctuaries for over 18 years.
The gorillas' personalities were assessed by keepers, volunteers, researchers and caretakers who knew the gorillas well. Their personality was scored with measures adapted from techniques for studying people and other primates.
Researchers found that out of four personality traits – dominance, extraversion, neuroticism and agreeableness – extraversion, which was associated with behaviours such as sociability, activity, play and curiosity, was linked with longer survival.
The study found that the link between extraversion and survival was not affected by age or gender, rearing condition or how many times the gorilla had moved location.
Researchers say these findings are consistent with studies in people which found that extraverts tend to live longer.
The study, carried out on western lowland gorillas is important in understanding how the relationship between personality and longevity of life evolved.
Dr Alex Weiss, of the University of Edinburgh's School of Philosophy, Psychology and Language Sciences, said: "These findings highlight how understanding the natural history of personality is vital to insuring the continued health and well-being of humans, gorillas and other great apes."
The study is published today in the Royal Society journal Proceedings of the Royal Society B: Biological Sciences. The collection of personality data in 1994 was funded by Zoo Atlanta, the Georgia Institute of Technology, and a Lincoln Park Zoological Society's Dr Scholl's Graduate Research Fellowship.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
