Strategy Use in Cognitive Performance Tasks: A Large-Scale Analysis in Adolescents
This study utilizes a data-driven framework to analyze a large sample of 4,531 Dutch adolescents, revealing that rotation and mirroring strategies are the most prevalent and strongly associated with higher accuracy in the Five-Dot visuospatial task.

Imagine your brain is a supercharged video game console, and every time you solve a puzzle, it's not just about hitting the right buttons to get a high score. It's about how you play. In the world of psychology, scientists have long been obsessed with the "score"—how many correct answers you get or how fast you finish. But just like watching a replay of a game without seeing the player's moves, a score alone doesn't tell you if someone is using a clever shortcut, a lucky guess, or a systematic plan. This is where the study of "cognitive strategies" comes in. Think of a strategy as a secret recipe or a specific playstyle a gamer uses to beat a level. Some players might just mash buttons randomly, while others might notice a pattern, like "if I jump left, then right, then left again, I always find the treasure." Understanding these hidden patterns helps us see how our brains organize information, especially when we are young and our brains are still building their most powerful circuits.
Now, picture a classic brain teaser called the Five-Dot Test. It's like a digital connect-the-dots game where you have five dots on a screen and a timer ticking down. Your job is to draw as many unique shapes as possible by connecting the dots with lines. Traditionally, researchers just counted how many shapes you made. But a team of researchers from Maastricht University decided to look closer. They wondered: Are these kids just drawing randomly, or are they using secret tricks to keep the shapes coming? They analyzed the drawings of over 4,500 teenagers (about 15 years old) who played this game for three minutes. Instead of just counting the shapes, they used a clever computer program to spot "clusters"—sequences of drawings where the student was clearly using a pattern, like flipping a shape like a mirror image or spinning it around like a wheel.
Here is what they found: The teenagers were full of surprises. Almost everyone (96%) was using some kind of trick to keep going. The most popular trick was "mirroring," where a student would draw a shape and then immediately draw its reflection, like looking in a mirror. About 96% of the students did this at least once. The second most common trick was "rotation," where they would spin a shape 90 degrees to make a new one. About 72% of the students used this. Interestingly, the students who used these tricks—especially the mirroring and spinning ones—tended to get higher scores than those who didn't. It's like finding out that the players who used a specific combo move in a video game were the ones reaching the highest levels.
The researchers also discovered that the length of the game mattered. When they looked at just the first minute of the game, fewer students were using these complex tricks. But as the clock ticked toward the full three minutes, more students started using these strategies. It seems that when the easy, "ready-made" shapes run out, the brain switches into "strategy mode" to keep the creativity flowing. The study suggests that while some students might stumble onto these patterns by accident, the ones who used them consistently tended to perform better. However, the authors are careful to note that they can't be 100% sure if every student intentionally planned these moves or if some just happened to draw them by chance. They also couldn't tell if a student was "right-handed" or "left-handed," which might influence whether they preferred spinning shapes clockwise or counter-clockwise.
In the end, this study is like upgrading the camera on a video game replay. Instead of just seeing the final score, we can now see the player's moves, their patterns, and their unique style. The researchers found that using strategies like flipping and spinning shapes is a common and helpful way for teenagers to tackle these puzzles. It suggests that when we look at how smart someone is, we shouldn't just count the answers; we should also look at the clever ways they found to get there. This new way of looking at the game could help teachers and scientists understand how young people think and solve problems, opening the door to better ways of measuring how our brains grow and learn.
