Goats prefer happy people

Dr Alan McElligott with a goat.  The goat likes him.  Dr McElligott is happy.


I love science.  You never know what type of earthshaking factoid may rear its weird head on any given day. 

Like two days ago.

When it was announced that goats like happy people.

And since goats don't appear to be following me around, I must not be happy.

Go figure.

I thought I was.

Here's the report.  It explains why goats may or may not be following you around.

Goats prefer happy people

Goats can differentiate between human facial expressions and prefer to interact with happy people, according to a new study led by scientists at Queen Mary University of London.  The study, which provides the first evidence of how goats read human emotional expressions, implies that the ability of animals to perceive human facial cues is not limited to those with a long history of domestication as companions, such as dogs and horses.

Writing in the journal Royal Society Open Science, the team describe how 20 goats interacted with images of positive (happy) and negative (angry) human facial expressions and found that they preferred to look and interact with the happy faces.

Dr Alan McElligott who led the study at Queen Mary University of London and is now based at the University of Roehampton, said: "The study has important implications for how we interact with livestock and other species, because the abilities of animals to perceive human emotions might be widespread and not just limited to pets."

The study, which was carried out at Buttercups Sanctuary for Goats in Kent, involved the researchers showing goats pairs of unfamiliar grey-scale static human faces of the same individual showing happy and angry facial expressions.

The team found that images of happy faces elicited greater interaction in the goats who looked at the images, approached them and explored them with their snouts. This was particularly the case when the happy faces were positioned on the right of the test arena suggesting that goats use the left hemisphere of their brains to process positive emotion.

First author Dr Christian Nawroth, who worked on the study at Queen Mary University of London but is now based at Leibniz Institute for Farm Animal Biology, said: "We already knew that goats are very attuned to human body language, but we did not know how they react to different human emotional expressions, such as anger and happiness. Here, we show for the first time that goats do not only distinguish between these expressions, but they also prefer to interact with happy ones."

The research has implications for understanding how animals process human emotions.

Co-author Natalia Albuquerque, from the University of Sao Paulo, said: "The study of emotion perception has already shown very complex abilities in dogs and horses. However, to date, there was no evidence that animals such as goats were capable of reading human facial expressions. Our results open new paths to understanding the emotional lives of all domestic animals."

An unexpected way to recover from a breakup

Image
Breaking up is truly hard to do. And recovery from a breakup can be even harder. Your friends may counsel you to put the whole thing out of your mind. But new research suggests that repeatedly reflecting on a break-up -- even through participation in a research study -- actually speeds emotional recovery. "Breakups are ubiquitous -- most adults have experienced at least one in their life -- and are typically very distressing," says Grace Larson of Northwestern University. After studying divorce and breakups for years using longitudinal, multi-method designs, Larson and her then-adviser David Sbarra of the University of Arizona wanted to study whether these research techniques on their own were affecting participants. One concern they had was that the studies could be harming participants, Larson says. "At first glance, it might seem like repeatedly reminding participants that they had just broken up -- and asking them to describe the breakup over and over --

Greek Bronze Age ended 100 years earlier than thought

Writing historical fiction set in the Greek Bronze Age?  Or simply enjoy reading this genre'?  Here's a study you may find interesting. C onventional estimates for the collapse of the Aegean civilization may be incorrect by up to a century, according to new radiocarbon analyses. While historical chronologies traditionally place the end of the Greek Bronze Age at around 1025 BCE, this latest research suggests a date 70 to 100 years earlier. www.weather-forecast.com Archaeologists from the University of Birmingham selected 60 samples of animal bones, plant remains and building timbers, excavated at Assiros in northern Greece, to be radiocarbon dated and correlated with 95.4% accuracy using Bayesian statistical methodology at the University of Oxford and the Akademie der Wissenschaften Heidelberg, Germany. Researcher Dr Ken Wardle says, 'These new results tell a story that is totall

Mood Instability and Your Characters

Image
You're putting together a character who's mood simply bounces all over the place, happy one moment, in a fit of rage the next.  Researchers at King's College London note that this sort of mood instability is part of a number of mental health disorders.  So how do you structure the personality and behavior of a character like this?  Below is the King's College report, along with a brief description from mentalhealth.com, of typical behavior, sometimes in the extreme, of a person who is very emotionally unstable.  This is offered strictly as a guide for crafting character in fiction - and NOT for the amateur diagnosis of the state of someone's mental health.  That is always best left to trained professionals. Another note about emotionally unstable behavior:  as any parent will tell you, this is how adolescents and teen-agers often behave.  It's a normal part of growing up - but it is a matter of degree .  In the extreme, however, this behavior can be diag

How the lives of Georgian gaolbirds and highwaymen shaped modern Britain

Writing historical fiction requires solid research of available materials and databases.  The key word here is available.   So news of a new publicly accessible database that allows an author to research a very interesting past era is priceless almost beyond words.   I expect some exciting fiction to come out of this announcement. Here's the story, with a link to the source in the attribution. *  *  *  *  * London Lives, a landmark project led by Professor Bob Shoemaker from the University of Sheffield and Professor Tim Hitchcock from the University of Sussex, has uncovered a mass of extraordinary new evidence which reveals how the lives of thousands of 18th-century poor and criminal Londoners helped shape modern Britain. Based on evidence made available in a publicly available database, the study sheds new light on the everyday lives of thieves, prostitutes, vagrants, highwaymen, con-men, paupers and jailbirds, revealing how their daily fight for survival led to t

Remember faces but not names? You got it wrong.

New research has revealed we are actually better at remembering names than faces The cringe-worthy experience of not being able to remember an acquaintance's name leads many of us to believe we are terrible with names. However, new research has revealed this intuition is misleading; we are actually better at remembering names than faces. With the Christmas party season fast approaching, there will be plenty of opportunity to re-live the familiar, and excruciatingly-awkward, social situation of not being able to remember an acquaintance's name. This cringe-worthy experience leads many of us to believe we are terrible at remembering names. However, new research has revealed this intuition is misleading; we are actually better at remembering names than faces.
