Thousands of years ago, when our human and canine ancestors first began their extraordinary relationship, there was something about certain types of wolves that distinguished them from the rest of the pack. Rather than a traditional form of intelligence, these pioneer dogs, or protodogs, had budding social skills that allowed them to approach and interact with humans. Edsel is reminiscent of these first dogs. Independent problem solving may not be a strong suit, but he has what counts - a desire to communicate and connect with you.
Edsel's empathy scores were off the charts. Empathy is the ability to feel what someone else is feeling. Humans are extremely empathetic; it is one of our best qualities. Empathy is not something we are taught; it is present even in young children, growing and strengthening as we get older.
Researchers have recently suggested that other animals also have empathy, or at least a basic form of empathy. If this is true, dogs are an ideal place to look. Humans and dogs go back thousands of years - enough time for the bond between us to develop into something special.
If most dogs are bonded to their owners, Edsel absolutely adores you.
It is quite impressive that, during a limited amount of time, Edsel yawned when you yawned. Humans laugh when we see someone laughing, and we cry when we see someone in distress. Our ability to "catch" the emotions of others is called emotional contagion. A common form of emotional contagion is yawning. If you see, hear or even think about someone yawning, you will probably feel an irresistible urge to yawn. Contagious yawning is related to empathy scores in adults.
If Edsel could take a human empathy test, he would probably score quite high! So far, only a few species besides humans have been shown to contagiously yawn. Although dogs may yawn when they are stressed, they also yawn socially. Contagious yawning has been seen in dogs, but not all dogs yawn. It looks like Edsel is one of the empathetic ones.
In this game, you timed how long Edsel held your eye contact. Before babies can hug or speak, they use eye gaze to bond with their mothers. Research with dogs has shown that a similar phenomenon may happen with owners and dogs. Owners whose dogs stared at them for longer had significant increases in the hormone oxytocin. Oxytocin, also known as the "hug hormone," is related to feelings of bonding, pleasure and affection.
Judging by the extraordinary length of time Edsel spent gazing soulfully into your eyes, you probably often find him staring at you for no reason. You might wonder if Edsel is trying to tell you something, like he is hungry, needs to go to the bathroom or has an opinion on what to do over the weekend. But Edsel may not want or need anything - he may be just hugging you with his eyes.
Communication is the foundation of many relationships, including our relationship with dogs. It's easy to take for granted that our dogs seem to read us like a book, but this ability is rare in the animal kingdom. Of all the species that have been studied, dogs are the champions at using our communicative gestures. Even chimpanzees, who are one of our closest living relatives, do not rely on human gestures as much as dogs do. Instead, chimpanzees try to figure out these types of problems on their own. Dogs are more like human infants who start using gestures as they begin learning language.
It looks like Edsel tended to switch back and forth between collaborative and self-reliant strategies. Sometimes he followed your communicative gestures, but sometimes he chose to ignore them. This could be because Edsel either struggles to read your cues, or because there was a treat in both places and Edsel didn't feel the need to look to you for help.
Although the pointing game may have seemed simple, the skills it requires are quite specialized. Dogs are one of the only animals that rely on human gestures - but even among dogs there is variation. Some dogs are more like infants and rely heavily on our communicative gestures, while other dogs are more like chimpanzees and try to solve problems on their own without our help. Edsel seems to use a mixed strategy. Because Edsel could see food in both places, he didn't really need your help, but occasionally chose to follow your gestures anyway.
Just like in the hand pointing game, Edsel thought he had better cover all bases by sometimes choosing the treat you pointed at and sometimes striking out on his own.
Edsel probably does not see you point with your foot very often, so this game was a way of seeing how flexibly Edsel can read new gestures. Giving animals a new version of a problem they have seen before is a common tactic used to reveal what strategy they are using to solve a problem.
By no means did Edsel do badly on this game; in fact, he developed quite a clever strategy. he developed a right or left side bias, meaning when he didn't know which side was correct, he went to one side every time. This is pretty clever, because 50% of the time he was correct.
Edsel scores as trustworthy in this game since he does not use your social information when deciding whether to take advantage of you. When you put the treat down in front of Edsel and said 'No,' you then presented him with different attentional states. In the first condition, you were watching Edsel directly. In the second condition you covered your eyes, and in the final condition you turned your back.
A wily dog would have waited until you could not see before they took the treat. In contrast, Edsel was more likely to take the treat when you were looking at him than if you had your back turned. This may seem a little audacious, but, in fact, it actually makes him trustworthy because he does not use your social information to deceive you.
These games examined how heavily Edsel relies on his working memory. Working memory is the kind of memory that allows your dog to keep information in mind for a few minutes and mentally manipulate it to solve problems.
In the memory games, Edsel had to understand that even though the treat disappeared from view, it still existed, and it was his job to find it. It looks like Edsel has a good working memory, but also uses other information, such as smell or social gestures, when making decisions and solving problems.
In this game, Edsel saw you put the treat under one cup, but point to the other cup. Edsel preferred to rely on the information in his working memory rather than what you pointed to. Even though you gave Edsel misleading information, he remembered where the treat was and chose to ignore you. This shows an independent thinker; you should be aware that in other situations Edsel might not listen to you if he thinks you are wrong.
Since dogs have such a keen sense of smell, you may have been surprised that after you switched the cups, Edsel used his memory over his sense of smell. He went to where he remembered seeing the treat hidden, rather than sniffing out where the treat was.
Because a dog's nose can sniff everything from narcotics to cancer, whenever we run a study where we hide a treat under one of two cups, the first question people always ask is, "Can't my dog just smell the food under the cup?" It was certainly our first question, but extensive research by half a dozen independent research groups has concluded that dogs do not rely on their sense of smell to find the food in these games.
If dogs were using smell, they would go directly to the cup with the hidden food. In fact, these studies found that dogs only choose the correct cup around half the time - which means they are guessing. Dogs do have an excellent sense of smell and can probably detect food if allowed to sniff both cups before choosing. But when you study their first choice, they cannot localize the food to a specific cup from a distance of six feet away.
Working memory is critical for animals that are endurance hunters such as wolves or feral dogs. Endurance hunters chase after prey for long periods of time, slowly wearing them out. During that long chase the prey may not always be in direct sight, so the hunter would have to remember where its prey was last seen.
Unlike his ancestors Edsel no longer needs to rely on his memory in order to find food; he has you for that! In this game, it looks like Edsel did not depend on his working memory, which indicates that he relies primarily on other skills to navigate his world. There is no need to worry! It is just one more piece of evidence that Edsel has his own cognitive style.
Edsel is the kind of dog that likes to see all the pieces before he solves the puzzle. Reasoning is the ability to solve a problem when you can't see the answer and have to imagine the solution.
Edsel scored more towards the impulsive end, which means he doesn't get caught up in the details - especially details that aren't right in front of him. There is no shame in this. The reasoning games are the most difficult in the Assessment and most dogs find them extremely challenging.
This was probably the most difficult game, and Edsel's performance was excellent. In this game, we presented Edsel with a problem and you provided some, but not all, of the information needed to solve it. When you showed Edsel the empty cup, you were providing indirect information on where the treat was - he had to make an inference that because that cup was empty, the treat must be in the other cup.
Just because Edsel did not choose the cup with the reward, it doesn't mean that he failed. In fact, this shows a strongly cooperative nature. By lifting up the empty cup, you were actually drawing attention to it, and Edsel preferred to choose this cup over the other. Edsel views you as a cooperative partner and assumed that you were trying to help him by showing him the correct cup.
In this game, Edsel demonstrated an excellent understanding of a fundamental property of the physical world - that one solid object cannot pass through another solid object.
Edsel had to infer that a piece of paper on an angle meant that a treat was hidden behind it. This talent would come in handy in the wild, since animals often have to keep track of objects that become hidden. To find these objects, animals have to maintain a representation of the object and predict where it might appear.
Humans intuitively understand basic physical phenomena like the solidity principle - it looks like Edsel does too.
