1 . Getting the “side-eye” look from your dog can make it seem like they are making a judgement about you, and some new studies suggest they really could be.
The ability to judge others’ intentions is an indicator of possessing “theory of mind” which was once thought to be unique to humans. However, new studies have shown that dogs can read human behaviour and have a preference to people who are more friendly or generous with food.
One such study published in 2023 aimed to see if dogs can tell the difference between humans who are “unwilling” or “unable” to give them a treat. 96 dogs were involved in both “unwilling” and “unable” scenarios (情境) designed for the study. Both scenarios involved a dog being placed on one side of a glass screen with small holes in it at nose-height, and an experimenter standing on the other. In the ‘unwilling’ scenario, the experimenter would hang a piece of sausage in front of the screen in a ‘teasing’ (戏耍的) manner, and approach one of the holes. But instead of passing it through the hole to the dog, they would then pull it out of its reach. For the “unable” scenario, the experimenter would again move the treat towards the hole while the dog watched, but “accidentally” drop it before they could pass it through.
The researchers observed that the dogs were much more patient, making more eye contact and staying closer to the screen after the “unable” scenario played out. In the “unwilling” scenario, however, the dogs looked at the experimenter less often, sat, lay down and wandered around more frequently.
Another study from 2021 tested for “theory of mind” in dogs in a similar way, but the dogs were able to walk round the screen to obtain the treat after witnessing the experimenter’s “unwilling” or “unable” behaviour. The main finding was that the dogs approached the experimenter significantly sooner in the unable scenario than in the unwilling scenario.
However, the researchers of the 2023 study challenged that the food dropped on the floor in the clumsy (笨拙的) manner might have motivated the dogs to approach the experimenter considering that they probably often obtain food dropped on the floor in their daily lives.
Now, more evidence has been provided that dogs distinguish between similar actions associated with different intentions. But how exactly they acquire such intention-reading abilities will be an exciting topic for future research.

2 . Pre-school children who spend time together take on one another's personalities, a new research has found. The study shows that environment plays a key role in shaping people's personalities. While genetics still forms the central part of the human psyche (心理), the research finds that personality traits (特征) are "contagious" (传染的) among children. "Our finding flies in the face of common assumptions that personality can't be changed," said Dr. Jennifer Neal, co-author of the study.
The researchers studied the personalities and social networks of two pre-school classes for a full school year. One of the classes was a set of three-year-olds, and the other a set of four-year-olds. Children whose friends were hard-working or outgoing gradually took on these personality traits over time. Psychology expert Dr. Emily Dublin said kids are having a far bigger effect on each other than people may realize.
The new study is not the first to explore the contagious effects of personality traits. A 2015 psychology study found that rudeness at work can be contagious as it travels from person to person "like a disease". The study found that seeing a boss being rude to an employee was enough to cause people to be rude to those around them.
The researchers questioned 6,000 people on the social "climate" in their workplaces, which included offices, hotels and restaurants. They found 75 percent of those who took part said they had been treated rudely at least once in the past year. And the study also suggests that merely seeing other people being subjected to rudeness made it more likely that a person would treat their colleagues in the same way. Rudeness could include leaving someone off an invite to a company event, sending unkind emails, finding fault with others or failing to give praise.
Dr. Torkelson believes companies need to be more aware of the harm that rudeness in the workplace can do as it can damage the working environment. She said better training could help to fight against the problem.
