When it comes to the problems caused by gender differences between men and women, there is always a debate. In fact, it is also true among animals. Apart from the behavioral problems caused by obvious physical differences, the Even cognition is different.

What is cognition? It refers to the ability of the human brain to process, store and extract information, which is what we generally call intelligence, such as observation, memory, and imagination. For dogs, it is mainly a performance of concentration, which includes navigation ability, memory ability, social learning ability, inhibitory control ability, empathy ability and so on. Some dogs may have outstanding social learning ability, but less memory and empathy, and some dogs may be the opposite.

In 2011, researchers at the University of Vienna conducted an experiment to understand the relationship between gender and cognition , wants to find out if a dog, like a human, remains curious enough to find its location even when the object cannot be seen, heard, or touched.

A total of 50 dogs were found in this experiment, breeds including Golden Retriever Retriever, Poodle Dog, AustralianSheepdog and mixed breeds, divided into 25 males and 25 bitch. The researchers tied two blue tennis balls of different sizes together with a rope, then placed the dog on the opposite side of the ball and used a plank as a block of view, and tested them in four scenarios:

· After the small ball rolls to the board, it will stop after a while;

· After the big ball rolls to the board, it will stop and then appear again;

· After the small ball rolls to the board, it will stop After that, the big ball will appear again;

· After the big ball rolls to the plank, the small ball will appear again after staying.

According to the experimental results, it was found that there were obvious differences in the reactions of male dogs and female dogs. The male dogs did not notice any changes in the size of the blue tennis balls at all, but the female dogs noticed it immediately. In the latter two scenes, the bitch stared at the sphere for about 36 seconds after seeing that the sphere coming out from the back was different from the previous one, which was 3 times longer than the previous scene when the sphere of the same size disappeared and reappeared. about.

Researchers from the University of Vienna have concluded that female dogs are more cognitively capable of this visual change than male dogs, at least when it comes to information processing. s difference. The reason is probably that changes have taken place in the process of evolution. Because bitches need to pay attention to the whereabouts of puppies at all times, but because the body odor of newly born puppies is almost the same, the sense of smell is obviously not enough, so they are more than male dogs. more dependent on vision. As for male dogs, their sense of smell is obviously higher than that of female dogs, so almost all the tasks that need to be completed in the tracking project are selected by male dogs.

But ask me who is smarter than who? Then I really can't decide, after all, it's just a different way of cognition, male dogs will perform better than female dogs under stressful conditions due to the influence of testosterone More competitive and superior to bitches in stamina and stamina. But gender differences also show up in areas other than cognitive abilities.

Aggressive

In dogs, especially for males, aggression is the best way to gain a competitive advantage and defend territory It can also prevent other dogs from wanting to occupy their own food or compete for bitches, and can also ensure their class status.

Although in daily life, dogs with such aggressiveness are not popular with humans, but in certain contexts, such as military dogs and guard dogs, they still need to be aggressive. Of course, this must have undergone rigorous training and supervision.

Compared with the male dog's attack reasons, the female dog appears to be single, only in the process of pregnancy and caring for the puppies, because of hormone reasons, the personality will be very sensitive, resulting in a strong tendency to attack. In interviews with 1,000 households with dogs, the female dog's aggression was mainly directed at other dogs of the same sex.

In a study of 20 dogs of different breeds, male dogs were more aggressive towards other dogs and strangers than female dogs, but once spayed , you can reduce this aggression, the results show that this aggression has a certain relationship with the level of androgen in the body.

· Lateral brain

Lisa Tomkins, a professor at the Australian University School of Medicine, found in a study that dogs with right-sided hemispheres turn their hair in a clockwise direction. Changes, the left side of the brain changes in a counterclockwise direction, and the direction of the hair rotation is closely related to the training performance of the guide dogs. The dogs with clockwise front chest hair rotation have a pass rate of 29% during the training process. , and the counterclockwise dog not only has twice the pass rate than the clockwise dog, but also has a more stable and energetic performance. Scientists speculate that the relationship between hair spin and brain development may be related to the fact that the nervous system and cortex share the same ectodermal embryonic start.

In the original lateralization study in dogs, where researchers covered strips of cloth and observed which paw they would use to try to move the strips away, more than 50 percent of dogs used the right Claws, 18% of dogs use the left paw, and the remaining 25% use the left and right bows. More than 70% of 50% of the dogs are bitches. Is it fair to say that female dogs use the right side of the brain more than male dogs.

If you are interested, in addition to the above, you can also try these methods at home,

· Give it a handshake command to see how many times his paw goes out first More;

· Put the food/toy under the sofa and see which paw sticks out first;

· Put a small piece of tape on the nose and see what he uses Which paw will take it off;

· Put the toy (such as a feeding ball) as far as he can see, making sure it is not sideways, and see which paw he uses to hold the toy ;

· If your dog has the habit of scratching the door, you can also see which paw he uses to enter the house.

These test methods are best repeated many times in order to count the number of times the dog uses the left and right paws, and to be more precise about which paw the dog is accustomed to.
