A new study from the Department of Ethology, Eötvös Loránd University, showed that dogs may not equally benefit from observing the ‘helpful action’ of a human demonstrator in the classic detour around a V-shaped fence task.
Those who are experienced with the world of ethological conferences, know all too well that if you present your work about dog behavior, the first (or second) question from the audience will be: “And did you check whether the breed of the dog had an effect on your results?”
Actually, this is not surprising as most people are familiar with the mindboggling variability of hundreds of dog breeds that differ not only in their appearance, but also in their behavior. It’s only natural to speculate that terriers would behave differently than Huskies, Border Collies would show different preferences than pointers, and so on.
There are of course many experiments in which ethologists found considerable breed differences. But social learning, which is the capacity for learning through observation of someone else’s actions, remained an interesting exception, until now. Although dogs are well known for their excellent ability to learn from other dogs, and more importantly, from humans, this significant feature remained stubbornly independent of their breed through more than two decades of investigations.
Now, with their new study published recently in the journal ‘Animals’, the researchers of the Department of Ethology showed that some dog breeds seem to be more honed towards human behavior than others, which helps them to improve their performance in an otherwise difficult spatial problem-solving task: to detour around an obstacle. Dr. Péter Pongrácz, who conducted many of the pioneering social learning experiments with dogs in the last two decades, was joined by Petra Dobos, an exceptionally promising undergraduate student, whose bachelor thesis was aimed towards the ambitious goal of finding breed-related differences behind dogs’ social learning skills.
The two researchers utilized the idea of sorting dog breeds into two functional groups: those who were selected for cooperatively working with their human handlers (such as herding dogs, pointers, retrievers); and those who mainly work without constant human guidance – the independent working dogs (such as terriers, sighthounds, spitz type breeds and livestock guarding dogs).
Petra tested nearly 100 dogs in the well-known ‘V-shaped fence detour’ test. Dogs had to find the reward behind the transparent wire-mesh fence, which is a hard task, as many dogs cannot perform the required detour within 1 minute, which is the standard duration of a trial. Dogs were tested in three consecutive trials, either without any further help (control group); or after witnessing Petra as she walked around the fence, demonstrating how to make a detour, before the second and third trials. Upon review of the results, it turned out that the independent and cooperative breeds were equally unsuccessful in the control condition, which was not a surprising result, regarding how hard is the detour task for dogs in general.
However, it turned out that when additional assistance was provided in the form of watching the helpful demonstrator, cooperative working dog breeds were in clear advantage.
Unlike their independently working cousins, cooperative dogs performed faster subsequent detours compared to their baseline trial. Independent dogs on the other hand, did not speed up their detours, even though they were also provided with the same demonstration of walking around the fence.
“The beauty of this finding lays in the fact that we did not find any specific dog breed to be especially talented in social learning” – said Dr. Pongrácz, supervisor of the research program. “The groups we assembled for the tests consisted of several unrelated dog breeds, positioned at distant branches on the genetic ‘tree’ of dogs, thus our results highlight the role of functional breed selection that has possibly been aimed at those capacities in dogs that enhance attention and interest towards human behavior.” Petra concluded the discussion with a remark regarding their future plans: “We won’t stop here of course. There are so many things still to discover, for example, whether the cooperative and independent dogs would equally regard our attention calling words interesting, or would we find the cooperative breeds as being more attracted to human encouragement?”

FINDINGS
Scientists at the UCLA Jonsson Comprehensive Cancer Center have identified potential new biomarkers that could indicate how someone diagnosed with metastatic melanoma will respond to immunotherapy treatment.
The researchers found when T cells are activated, they release a protein called CXCL13, which helps attract more B cells and T cells to the tumor site. The B cells then show the T cells specific parts of the tumor, which leads to increased activation of the T cells and their ability to fight the cancer. This cooperation between T cells and B cells was associated with improved survival in patients diagnosed with metastatic melanoma ...
CHICAGO, June 26, 2023 – A new American Dental Association (ADA) clinical practice guideline suggests conservative methods to treat tooth decay in primary and permanent teeth could lead to better outcomes when used with common restorative materials like fillings or caps. An expert panel of dentists developed the first-ever guideline on this topic after extensive review of approximately 300 published studies.
The guideline, published in the July issue of The Journal of the American Dental Association, contains 16 recommendations regarding treatment ...
Research shows that school suspensions do not deter but instead amplify future punishment, what has been termed labeling theory: the idea that the symbolic label that comes with a suspension shapes how others perceive students. But few studies have examined racial and ethnic differences in this process, even though critical race theory (CRT) suggests that the consequences of suspension likely differ across racial and ethnic groups due to stereotypes.
In a new study, researchers examined how the relation between suspension and subsequent arrest differs for White, Black, and Hispanic students. They found that suspension ...
UNIVERSITY PARK, Pa. — In an attempt to rescue a rare darter in the lower Susquehanna River, a Penn State research team, working with the Pennsylvania Fish and Boat Commission, has determined that the fish is a distinct subspecies found nowhere else. And that makes the effort to restore its population even more important, the researchers say.
A yellow- to olive-colored member of the darter family with dark bars often arrayed in zebra fashion, the Chesapeake logperch is typically just a few inches long, with a small mouth and a short, conical snout. It is believed to only ever have inhabited the lower drainages of the Susquehanna and Potomac rivers, and it has not been seen ...

A new study co-authored by Patrick Hill, associate professor of psychological and brain sciences, offers an important message for our times: A sense of purpose in life — whether it’s a high-minded quest to make a difference or a simple hobby with personal meaning — can offer potent protection against loneliness.
“Loneliness is known to be one of the biggest psychological predictors for health problems, cognitive decline, and early mortality,” Hill said. “Studies show that it can ...
Demand for modern biofuels is expected to grow substantially in order to mitigate climate emissions. However, they are far from being a climate neutral alternative to gasoline and diesel. A new study in Nature Climate Change shows that under current land-use regulations, CO2 emission factors for biofuels might even exceed those for fossil diesel combustion due to large-scale land clearing related to growing biomass. Before bioenergy can effectively contribute to achieving carbon neutrality, international agreements need to ensure the effective protection of forests and other natural lands by introducing carbon ...
The biological roots of autism continue to perplex researchers, despite a growing body of studies looking at an increasing array of genetic, cellular and microbial data. Recently, scientists have homed in on a new and promising area of focus: the microbiome. This collection of microbes that inhabit the human gut has been shown to play a role in autism, but the mechanics of this link have remained awash in ambiguity. Taking a fresh computational approach to the problem, a study published today in Nature Neuroscience sheds new light on the relationship between the microbiome and autism. This research — which originated ...
(COLUMBUS, Ohio) – Firearms are the leading cause of death among children and teens 1-19 years old in the United States. According to new research from Nationwide Children’s Hospital, most unintentional firearm fatalities in which a child shoots another child involve boys, occur in the child’s home or at the home of a friend, and involve firearms that were stored loaded and unlocked.
In a new study, researchers at the Center for Injury Research and Policy at Nationwide ...
