Can you believe your eyes? A recent experiment suggests that the answer to that question may depend on your age.

Martin Doherty, a psychologist at the University of Stirling in Scotland, led the team of scientists. In this experiment, Doherty and his team tested the perception(观察力) of some people, using pictures of some orange circles. The researchers showed the same pictures to two groups of people. The first group included 151 children aged 4 to 10, and the second group included 24 adults aged 18 to 25.

The first group of pictures showed two circles alone on a white background. One of the circles was larger than the other, and these people were asked to identify the larger one. Four-year-olds identified the correct circle 79 percent of the time. Adults identified the correct circle 95 percent of the time.

Next, both groups were shown a picture where the orange circles, again of different sizes, were surrounded by gray circles. Here's where the trick lies in. In some of the pictures, the smaller orange circle was surrounded by even smaller gray circles —making the orange circle appear larger than the other orange circle, which was the real larger one. And the larger orange circle was surrounded by even bigger gray circles—so it appeared to be smaller than the real smaller orange circle.

When young children aged 4 to 6 looked at these tricky pictures, they weren't fooled—they were still able to find the bigger circle with roughly the same accuracy as before. Older children and adults, on the other hand, did not do as well. Older children often identified the smaller circle as the larger one, and adults got it wrong most of the time.

As children get older, Doherty said, their brains may develop the ability to identify visual context. In other words, they will begin to process the whole picture at once: the tricky gray circles, as well as the orange circle in the middle. As a result, they're more likely to fall for this kind of visual trick.

When you are paying upwards of £15,000 a year to have your child privately educated, the big sum of money for extra tuition(学费) may not sit well with you. But that is exactly what seems to be happening. An increasing number of parents look to "top-up" their child's already expensive education with a private tutor.

According to managing director Nevil Chiles of Kensington&Chelsea Tutors, the agency's students tend to fall into two groups. There are those who are struggling with a particular subject and benefit from one-to-one tuition. The second group consists of students who are already excellent but whose parents want to ensure they go on to their preferred school or university.

"We felt Mica needed help with exam technique and we also realized that she did much better one-to-one than in a classroom," explains Bowman, who contacted Kensington & Chelsea Tutors on the advice of a friend who used them for her sons, including one who was attending Eton."Mica has established a good relationship with her tutors and has gained confidence as a result of the tutoring." adds Bowman.

Guinness World Records has long been recording some of the most amazing and astonishing travel and tourism facts. Here we are sharing some of the most unbelievable record-breaking accounts, all fully fact-checked and Guinness-approved.

Largest Ice Structure—The Ice Hotel in Sweden

Each year, the ice hotel in Jukkasjarvi, Sweden, is rebuilt from blocks of frozen ice from the nearby River Torne. Covering an area of 5,500 square metres, the hotel is unsurprisingly open seasonally, from December to March, when it melts away. In 2015, the hotel celebrated its 25th anniversary, complete with an ice bar, an ice church and ice bedrooms—one even featured a London Tube carriage made entirely of ice.
