Even before they can read, young children are visualizing letters and other objects with the same strategies adults use
Shannon Pruden, Florida International University and Karinna Rodriguez, Florida International University What do puzzles, gymnastics, writing and using maps all have in common? They all rely on people’s ability to visualize objects as they spin, flip or turn in space, without physically moving them. This is a spatial skill that developmental psychologists call mental rotation. Whether a person is navigating a new city or doing a cartwheel, they must use mental rotation skills to move shapes or objects in their mind and make sense of where their bodies are going and what surrounds them. When children play with puzzles, building blocks or pattern games, they are also practicing mental rotation. Over time, these skills support learning in math, science and reading. This can look like visualizing pulley systems in physics or seeing the differences between similar-looking letters such as b and d, which young children often confuse. Strong mental rotation skills also lay the foundation for doing well in school and developing interest in careers in science, technology, engineering and math. Most preschool-age children are not yet learning to read – but it turns out they are still using some of these same spatial reasoning skills as they think about the world around them. We are scholars of, developmental science and were curious to find out how children as young as 3 years old mentally rotate objects. While there is research on the age at which children can mentally rotate objects, less is understood about how children are solving mental rotation problems. We found in our research, conducted from 2022 to 2023, that young children are using the same problem-solving strategies as adults when they solve a mental rotation task.
Children think visually, just like adults
We used eye-tracking technology to understand how a sample of 148 children, all between 3 and 7 years old, solved different mental rotation problems. Eye-trackers use harmless infrared light to capture eye movements. This technology lets us observe how children solve these problems in real time. As part of our study, we showed each child a large picture of items such as a fire truck, as well as two smaller pictures of the same truck, one placed above the other and positioned slightly differently. Children were asked to say which small picture on the right matched the large one on the left. In this example, the correct answer is the top picture, because that top fire truck can be rotated to match the large fire truck. The bottom fire truck was a mirrored image, and no matter how much you rotate it, it will never match the large fire truck.Children looked at pictures of fire trucks as part of a research study to assess how they manipulated the object in their heads.Karinna Rodriguez While the children thought about their response, the eye-tracker, mounted right below the computer screen, recorded their eye movements. By looking at where and for how long children looked at each image, we figured out what kind of strategy they were using. Some children focused on fewer parts of the object and spent less time studying its details. This suggests they used a holistic strategy, meaning they took in the whole image at once, instead of breaking it into pieces. These children mentally rotated the entire object to solve the task. Other children focused on parts of the object and spent more time studying its details. This suggests they broke the image down into pieces instead of visualizing the image as a whole, known as a piecemeal strategy. Our findings support prior work showing that children generally use these two visual approaches to solve mental rotation problems. This study helped us learn where children look while solving puzzles and identify how they solve these problems – without ever having to ask the child, who might be too young to explain, about their process. Children were more likely to turn the whole image instead of breaking it down into pieces, a pattern of problem solving adults typically also use. This means that even very young children are already thinking about how objects move and turn in space in ways that are more advanced than expected.An example of a mental rotation task that can show how people are visually moving objects in their minds.Angie Mackewn, CC BY
Supporting children’s visual skills
Knowing how young children mentally rotate objects may help researchers, teachers and parents understand why some children struggle with learning to read. Children who break an image down into pieces, instead of visualizing it as a whole, to solve mental rotation problems may be the very same children who struggle with discriminating similar-looking letters such as p and q and may later be diagnosed with dyslexia. Parents can play an important role in building their child’s mental rotation skills. Parents can help children by offering them opportunities to practice rotating real objects with toys such as three-dimensional puzzles or building blocks. Tangrams – flat, colorful puzzles that come in different shapes – can be used to practice breaking down shapes of animals into pieces. Parents can encourage their child to look for shapes that match parts of the animal or object they are building. Nov. 8 is International STEM Day, a celebration of all things science, technology, engineering and mathematics. Research like ours provides valuable guidance for designing early STEM activities and educational tools. By directly observing children’s problem solving in real time, we can develop better ways for educators and toy makers to support strong spatial thinking from an early age. To celebrate, we encourage people to engage in activities that test their spatial skills, such as ditching the GPS for the day or playing a game of Tetris. Mental rotation is a powerful skill that helps us understand and interact with the surrounding physical world. From solving puzzles to reading maps, mental rotation plays a role in many everyday activities. Building mental rotation abilities can improve children’s performance in subjects such as reading, math and science and may inspire future careers in STEM fields.

The Unfavorable Semicircle Mystery: The YouTube Channel That Uploaded Tens of Thousands of Cryptic Videos
In 2015, the YouTube channel Unfavorable Semicircle gained attention for its enigmatic and abundant video uploads, totaling over 70,000 before its deletion in 2016. Theories about its purpose vary, from automated content generation to digital art experimentation, leaving its intent unresolved.
In the vast digital landscape of the internet, strange phenomena occasionally emerge that leave investigators, tech enthusiasts, and everyday viewers scratching their heads. One of the most puzzling cases appeared in 2015, when a mysterious YouTube channel called Unfavorable Semicircle began uploading an astonishing number of cryptic videos.
Within months, the channel had published tens of thousands of bizarre clips, many of which seemed random, incomprehensible, and visually chaotic. But as internet detectives began analyzing the content more closely, they discovered that these videos might not have been random at all.
The Sudden Appearance of an Internet Mystery
The Unfavorable Semicircle channel reportedly appeared in March 2015, with its first uploads arriving in early April.
Almost immediately, the channel began publishing videos at an incredible pace. Observers estimated that the account uploaded thousands of videos per week, sometimes multiple videos per minute. By the time the channel disappeared in early 2016, researchers believed it had uploaded well over 70,000 videos, possibly far more.
The scale alone made the project seem impossible for a human to manage manually.
Most of the videos shared similar characteristics:
Extremely short or very long runtime
Abstract visuals such as flashing colors, static, or distorted imagery
Little or no audio, or heavily distorted sounds
Titles made of random characters, symbols, or numbers
To casual viewers, the videos looked like pure digital noise. However, online investigators suspected something more deliberate was happening.
Hidden Images Discovered
The mystery deepened when researchers began extracting individual frames from some videos.
When thousands of frames from certain clips were stitched together, the results sometimes formed coherent images. One of the most famous examples involved a video titled “LOCK.” While the footage appeared chaotic at first, combining the frames revealed a recognizable composite image.
This discovery suggested the videos were carefully constructed rather than random uploads.
Theories About the Channel’s Purpose
Because the creator never explained the project, several theories emerged across Reddit, YouTube, and internet forums.
Automated Experiment Many believe the channel was created using automated software that generated and uploaded content at scale.
Alternate Reality Game (ARG) Some viewers suspected the channel might be part of a hidden puzzle or digital scavenger hunt.

Encrypted Communication Others compared the channel to Cold War “numbers stations,” suggesting the videos could contain coded messages.
Digital Art Project Another theory suggests the channel was an experimental art project exploring algorithms, data, and visual noise.
Despite years of investigation, no single explanation has been confirmed.
Why the Channel Disappeared
In February 2016, YouTube removed the channel, reportedly due to spam or automated activity violations.
By that time, the channel had already become a minor internet legend. Fortunately, some researchers managed to archive a large portion of the videos before they disappeared.
Even today, archived clips continue to circulate online as investigators attempt to decode them.
Unfavorable Semicircle: The Most Bizarre YouTube Mystery
Other Mysterious YouTube Channels
The Unfavorable Semicircle mystery is not the only strange case on YouTube.
One well-known example is Webdriver Torso, a channel that uploaded hundreds of thousands of videos showing red and blue rectangles with simple beeping sounds. Internet speculation ran wild before Google eventually confirmed it was an internal YouTube testing account.
Another example is AETBX, which posts distorted visuals and unusual audio that some viewers believe contain hidden patterns or encoded information.
These cases highlight how automation, experimentation, and creativity can sometimes blur the line between technology and mystery.

A Digital Mystery That Remains Unsolved
Nearly a decade later, the true purpose behind Unfavorable Semicircle remains unknown.
Was it a sophisticated experiment? A piece of algorithmic art? Or simply an automated test that accidentally captured the internet’s imagination?
Whatever the explanation, the channel stands as a reminder that even in a world filled with billions of videos and endless information, the internet can still produce mysteries that challenge our understanding of technology.
Why Internet Mysteries Still Fascinate Us
Stories like Unfavorable Semicircle capture attention because they combine technology, creativity, and the unknown. They invite people from around the world to collaborate, analyze patterns, and search for meaning hidden in the noise.
And sometimes, the most intriguing part of the mystery is that the answer may never fully be known.

Byron Allen’s Starz Stake Signals Bigger Moves in the Streaming Industry
Byron Allen’s Starz: Byron Allen has acquired a 10.7% stake in Starz Entertainment for approximately $25 million, signaling his long-term media strategy amidst industry consolidation. This investment positions him influentially in the evolving streaming market despite intense competition.

Byron Allen’s Starz investment
Media entrepreneur Byron Allen has taken another step toward expanding his growing media empire. Through his family office, Allen recently acquired a 10.7% stake in Starz Entertainment, purchasing the shares from a fund managed by former U.S. Treasury Secretary Steven Mnuchin.
The transaction, valued at approximately $25 million, gives Allen a significant minority position in the premium cable and streaming platform. While the investment itself may seem modest compared to the billion-dollar deals common in Hollywood, analysts say the move could signal a larger strategy unfolding in the rapidly evolving streaming industry.
Why the Starz Deal Matters
The shares were sold by Mnuchin’s Liberty 77 Capital fund, which previously invested in the company when Starz was still connected to its former parent, Lionsgate.
In 2025, Lionsgate completed a corporate restructuring that separated its operations into two distinct companies:
Lionsgate Studios – responsible for film and television production
Starz – focused on premium cable and streaming services
Following the spin-off, Starz became an independent publicly traded company. As a result, investors are still determining the platform’s long-term value in an increasingly crowded streaming marketplace.
Despite facing intense competition from larger platforms such as Netflix, Disney+, and Amazon Prime Video, Starz continues to maintain a strong subscriber base and recognizable content franchises.

Byron Allen’s Long-Term Media Strategy
Allen’s investment strategy has long focused on owning media distribution and infrastructure rather than simply producing content.
The Weather Channel
Dozens of local television stations across the United States
Multiple niche cable networks and digital platforms
Over the past several years, Allen has also pursued larger acquisitions, reportedly exploring deals involving companies such as Paramount Global and BET Media Group. While those deals did not materialize, they signaled his ambition to expand Allen Media Group into a major force in global media ownership.
The Bigger Picture: Industry Consolidation
Allen’s investment arrives during a time of significant disruption in the entertainment business. Traditional cable television continues to decline as audiences migrate toward streaming platforms. At the same time, major studios and media companies are struggling to make streaming services consistently profitable.
Industry observers believe these pressures could lead to a new wave of consolidation across Hollywood and the streaming sector. Smaller platforms like Starz could become attractive acquisition targets for larger companies seeking additional subscribers and content libraries.
A Potential Hidden Opportunity
For now, Allen’s 10.7% stake does not give him control of Starz. However, it does provide influence as one of the company’s larger shareholders and leaves open the possibility of increasing his ownership in the future.
If consolidation accelerates and streaming platforms begin merging or forming partnerships, assets like Starz could become significantly more valuable. For Byron Allen—whose career began as a stand-up comedian before evolving into one of the most prominent independent media owners in America—the investment may represent another calculated step in a decades-long strategy built around media ownership and long-term growth.
