He poses an interesting question about the actual culprit for the dog aggression problem, which is not even a dog! Next, he will explain how important understanding dog cognition is to training strategies. Hare will discuss how, unfortunately, not all cultures love dogs, and some see them as food and pests.
He suggests ways that humans can live with dogs for mutual benefit. Taking all that you've learned into account, Dr. Hare then discusses how Dognition is revolutionizing what we know about dogs and how beneficial it could be to your relationship with your dog as well as for science!

Making references to studies on apes, human children and a few other species, the course explores some of the cognition capabilities of dog compared to other animals and to us, with an interesting insight on domestication and self domestication.
While most the course content was interesting, however, I found quite annoying the continual shoving of the course author's book and site in the videos, especially since a few lecture and quizzes were dedicated exclusively to them as well. I also found some of lectures as the one about dog aggression fairly superficial, giving me the impression they were added as an afterthought. I'm not unhappy to have taken this course, but it's not one I would recommend in a particular manner either. Was this review helpful to you? The class was interesting and it helped me to understand dogs better.
Hare did a good job of explaining everything he taught every week. I felt like I understood everything I was learning in his class. I would recommend this class to anyone who wants to understand dogs better. I really enjoyed this course. I would have given it 5 stars if all the dognition exercises had been open to participants. Thank you. Very glad take a New knowlage. Dog trainer. Make and training dog.
Sport, teacher. They relied on their memory instead of following a deceptive human gesture or the olfactory cues potentially given off by a hidden treat when its location was surreptitiously switched from where the dog had initially seen it hidden. They also were able to locate a treat they had seen hidden after increasing delays of up to two and half minutes. Dogs also solved the solidity task by choosing the paper propped up by the hidden treat significantly more than the paper lying flat that could not have food underneath.
Meanwhile, positive but relatively weak evidence was observed for contagious yawning and the effect of the human watching vs. Contagious yawning was observed in the Beta but not the Live data set echoing variability in contagious yawning in the published literature. Dogs showed sensitivity to being watched in the Live data set only when their owner covered their eyes but not when they turned their back.
They showed no sensitivity to being watched in the Beta data set. Finally, we found no evidence of dogs using the principle of exclusion in locating hidden food during the inferential reasoning task in either the Beta or Live data sets. These findings largely replicate previous laboratory results that utilized methods closest to what was provided to our citizen scientists see Table 3. Five of the seven cognitive tasks that allow for quantitative comparison do not reveal significant differences.
Arm pointing, foot pointing, memory versus smell, memory delay, and physical reasoning all produce similar findings as observed in published studies. The memory versus pointing exercise is also consistent with the previous finding that dogs do not rely on a pointing gesture when they have just seen a treat being hidden in another location. However, our citizen science data revealed a strong preference by dogs to rely on their memory over a deceptive pointing gesture whereas previously published data found that dogs simply chose at chance levels [ 44 ].
Although, in our Live data set dogs tested by citizen scientists actually performed significantly below chance preferring to choose the cup they were shown was empty i.
While we did not see the high level of contagious yawning reported in Joly-Mascheroni et al [ 45 ], this may not be surprising since the phenomenon has not been consistently replicated by other labs e. The citizen data that differed most from previous published work was the watching exercise.
Dogs tested by citizen scientists were reported to wait 10—15 seconds longer in each of the three conditions than in Call et al [ 14 ]. Only by considering the Live dataset in isolation is there any evidence that dogs were sensitive to being watched when retrieving forbidden treats. It may be that methodological differences between laboratory techniques and our citizen science approach underlie these differences see SI.
For example, this measure may be more sensitive to who is conducting the experiment than other tasks since here it was always a familiar owner but in conventional studies it is often an unfamiliar experimenter e. In addition, dogs may behave differently in this context at home relative to an unfamiliar cognitive testing center. Finally, the difference may be due to different approaches to sampling. By definition citizen science is going to produce a qualitatively different type of data than conventional laboratory approaches [ 51 ].
In addition, each discipline will face its own unique challenges implementing citizen science research [ 28 ]. Our citizen science program was designed to take in to consideration the challenges that participants might have in conducting behavioral experiments reliably [ 51 ]. Our live dataset had the added protection of a redo button designed to help identify trials in which participants might have made a methodological error. Use of the redo button was consistent with participants using the button to correct the occasional error but generally feeling that they followed the procedures satisfactorily.
A comparison of dog trainers to non-trainers also provides another type of initial test for experimental bias.
The effects of domestication and ontogeny on cognition in dogs and wolves
If familiarity with dog handling altered results, one would predict that the dogs of professional trainers would differ from the general population. However, we found no difference. Future follow-up tests and questionnaires will allow us to further probe this possibility. Finally, post hoc examinations of the results suggest participants did not intentionally or unintentionally manipulate the data in obvious ways. If owners were consistently exaggerating their results, citizen-tested dogs would be predicted to outperform laboratory-tested dogs across tasks.
Instead, citizen-tested dogs performed poorly on the most challenging test inferential reasoning while performing almost identically to lab-tested dogs on tasks in which dogs are known to excel using gestures. This is not the expected pattern if participants were consistently exaggerating results.
Together with the replication of previously published phenomena, internal replications between the Live and Beta datasets, and the similarity between results of those who frequently and infrequently used the redo button, it seems that participants were largely willing and able to follow instructions. Like many other citizen science projects, our data seems to be of sufficient quality that it will help suggest where hypothesis driven research in more conventional research laboratories can be directed to either confirm or extend findings from citizen science [ 28 ].
Our factor analysis represents the first example of how citizen science might be applied to broach questions requiring larger datasets than typical in traditional lab-based approaches to studying dog cognition.
The Social Dog - 1st Edition
Our exploratory factor analysis suggests that multiple domains of cognition best explain individual differences. Performance on all of the tasks did not simply load together on one axis that explained the majority of individual variability. The Beta dataset even suggests a possible fourth reasoning factor that was not observed in the Live dataset. While future research may show a different set or number of factors, our data strongly suggest that dog cognition will not be easily explained by a single factor.
While these citizen science results should be considered preliminary, they clearly point to an exciting area where effort in conventional laboratory settings might be focused. When used in conjunction with more conventional and controlled laboratory approaches, citizen science promises to help push the study of dog psychology toward new frontiers.
The question and potential responses that participants answered after each trial in each task. More than twenty participants used the redo button in only two tasks in the Live data. Comparing these two tasks reveals no difference in performance between the two groups. Means for Back Turned and Eyes Covered represent difference scores between waiting times in each condition subtracted from the Watching condition.
