Children can be systematic problem-solvers at younger ages than psychologists had thought – new research
Child psychologists: Celeste Kidd’s research challenges long-standing ideas from Jean Piaget about children’s problem-solving abilities. Her findings show that children as young as four can independently utilize algorithmic strategies to solve complex tasks, contradicting the belief that systematic logical thinking develops only after age seven. This insight highlights the importance of nurturing algorithmic thinking in early education.

I’m in a coffee shop when a young child dumps out his mother’s bag in search of fruit snacks. The contents spill onto the table, bench and floor. It’s a chaotic – but functional – solution to the problem.
Children have a penchant for unconventional thinking that, at first glance, can look disordered. This kind of apparently chaotic behavior served as the inspiration for developmental psychologist Jean Piaget’s best-known theory: that children construct their knowledge through experience and must pass through four sequential stages, the first two of which lack the ability to use structured logic.
Piaget remains the GOAT of developmental psychology. He fundamentally and forever changed the world’s view of children by showing that kids do not enter the world with the same conceptual building blocks as adults, but must construct them through experience. No one before or since has amassed such a catalog of quirky child behaviors that researchers even today can replicate within individual children.
While Piaget was certainly correct in observing that children engage in a host of unusual behaviors, my lab recently uncovered evidence that upends some long-standing assumptions about the limits of children’s logical capabilities that originated with his work. Our new paper in the journal Nature Human Behaviour describes how young children are capable of finding systematic solutions to complex problems without any instruction. https://www.youtube.com/embed/Qb4TPj1pxzQ?wmode=transparent&start=0 Jean Piaget describes how children of different ages tackle a sorting task, with varying success.
Putting things in order
Throughout the 1960s, Piaget observed that young children rely on clunky trial-and-error methods rather than systematic strategies when attempting to order objects according to some continuous quantitative dimension, like length. For instance, a 4-year-old child asked to organize sticks from shortest to longest will move them around randomly and usually not achieve the desired final order.
Psychologists have interpreted young children’s inefficient behavior in this kind of ordering task – what we call a seriation task – as an indicator that kids can’t use systematic strategies in problem-solving until at least age 7.
Somewhat counterintuitively, my colleagues and I found that increasing the difficulty and cognitive demands of the seriation task actually prompted young children to discover and use algorithmic solutions to solve it.
Piaget’s classic study asked children to put some visible items like wooden sticks in order by height. Huiwen Alex Yang, a psychology Ph.D. candidate who works on computational models of learning in my lab, cranked up the difficulty for our version of the task. With advice from our collaborator Bill Thompson, Yang designed a computer game that required children to use feedback clues to infer the height order of items hidden behind a wall, .
The game asked children to order bunnylike creatures from shortest to tallest by clicking on their sneakers to swap their places. The creatures only changed places if they were in the wrong order; otherwise they stayed put. Because they could only see the bunnies’ shoes and not their heights, children had to rely on logical inference rather than direct observation to solve the task. Yang tested 123 children between the ages of 4 and 10. https://www.youtube.com/embed/GlsbcE6nOxk?wmode=transparent&start=0 Researcher Huiwen Alex Yang tests 8-year-old Miro on the bunny sorting task. The bunnies are hidden behind a wall with only their sneakers visible. Miro’s selections exemplify use of selection sort, a classic efficient sorting algorithm from computer science. Kidd Lab at UC Berkeley.
Figuring out a strategy
We found that children independently discovered and applied at least two well-known sorting algorithms. These strategies – called selection sort and shaker sort – are typically studied in computer science.
More than half the children we tested demonstrated evidence of structured algorithmic thinking, and at ages as young as 4 years old. While older kids were more likely to use algorithmic strategies, our finding contrasts with Piaget’s belief that children were incapable of this kind of systematic strategizing before 7 years of age. He thought kids needed to reach what he called the concrete operational stage of development first.
Our results suggest that children are actually capable of spontaneous logical strategy discovery much earlier when circumstances require it. In our task, a trial-and-error strategy could not work because the objects to be ordered were not directly observable; children could not rely on perceptual feedback.
Explaining our results requires a more nuanced interpretation of Piaget’s original data. While children may still favor apparently less logical solutions to problems during the first two Piagetian stages, it’s not because they are incapable of doing otherwise if the situation requires it.
A systematic approach to life
Algorithmic thinking is crucial not only in high-level math classes, but also in everyday life. Imagine that you need to bake two dozen cookies, but your go-to recipe yields only one. You could go through all the steps of making the recipe twice, washing the bowl in between, but you’d never do that because you know that would be inefficient. Instead, you’d double the ingredients and perform each step only once. Algorithmic thinking allows you to identify a systematic way of approaching the need for twice as many cookies that improves the efficiency of your baking.
Algorithmic thinking is an important capacity that’s useful to children as they learn to move and operate in the world – and we now know they have access to these abilities far earlier than psychologists had believed.
That children can engage with algorithmic thinking before formal instruction has important implications for STEM – science, technology, engineering and math –education. Caregivers and educators now need to reconsider when and how they give children the opportunity to tackle more abstract problems and concepts. Knowing that children’s minds are ready for structured problems as early as preschool means we can nurture these abilities earlier in support of stronger math and computational skills.
And have some patience next time you encounter children interacting with the world in ways that are perhaps not super convenient. As you pick up your belongings from a café floor, remember that it’s all part of how children construct their knowledge. Those seemingly chaotic kids are on their way to more obviously logical behavior soon.

How extraterrestrial tales of aliens gain traction
The narrative explores humanity’s intrigue with extraterrestrial entities, juxtaposing evolutionary processes with claims of alien interventions, ultimately emphasizing the need for scientific evidence over fantastical stories. Aliens!

One night, upon returning to the cave that his tribe calls home, the monkey-humanoid Moon-Watcher finds a strange crystal object, a kind of monolith that fascinates him at first, but then quickly loses his interest when he discovers that it is not edible. Soon after, the true purpose of the monolith is revealed to be none other than penetrating the minds of our ancestors to induce new abilities that, over time, will cause the development of an intelligence capable of creating new technology.
Many readers will recognise this scene from the novel 2001, A Space Odyssey, by Arthur C. Clarke, and the film of the same name, directed by Stanley Kubrick. It almost goes without saying that the crystal monolith in question is the work of an extraterrestrial civilisation that observes life on other planets and “experiments” on them to encourage the development of intelligence in as many parts of the cosmos as possible.
Seeking simple answers to complex questions
Understanding how we, as a species, came to be intelligent is one of the great enigmas of evolutionary study. Small mutations, followed by a process of natural selection to choose the most advantageous, seems too slow a process for structures as complex as the human nervous system or brain to emerge. It is this very complexity that allows millions of neurons to communicate with each other, resulting in the emergence of qualities such as the ability to respond voluntarily to environmental stimuli, or to ask questions about the very nature of humankind and the universe.
Nowadays, we know that there are evolutionary mechanisms that have lead to great leaps in terms of complexity, but that does not stop people from turning to non-human forces – Gods, extraterrestrials, spiritual energies – to explain things that are difficult to comprehend.
This has always been the case, in all human cultures. A classic example would be attributing atmospheric events – thunder, lightning, floods – to the wrath of God. These ideas came about before humans had ever left the ground, so it is no surprise that we turned our eyes even higher – to extraterrestrials – to explain other phenomena that we could only observe once travelling at high altitudes became part of our daily lives.
The allure of the unknown
The possibility that we might have been visited by beings from other worlds has always fascinated us. The element of mystery, of the unknown, only makes it more interesting.
Any phenomenon is made all the more enticing when it seems it is being covered up or hidden for secretive reasons. The attractiveness of conspiracies often leads people towards ideas which have no scientific basis, such as the belief that the Earth is flat, that humans never set foot on the Moon, or that vaccines can control our behaviour.
Even though these ideas have repeatedly been shown to be untrue, their rapid dissemination through social media, using simple, blunt language that appeals to emotion over logic, makes them very powerful weapons.
The supposed “proof” of alien visits to our planet ranges from specific Bible passages to ancient stone carvings portraying creatures or objects that may appear to be aliens or spacecraft. The latter often take the form of flying saucers.
However, we cannot forget that humans have always created imaginary creatures that resemble them and attributed them with magical powers. When imagining Gods, humans have given them a human appearance, and almost always imagined them as living in the sky.
When we look at these representations through modern eyes, we associate them with extraterrestrial beings or structures, when in fact they could be referring to a range of different things.
When unproven stories become larger than life
Recently, in the United States Congress, UFOs (currently known as UAPs: “Unidentified Anomalous Phenomena”) are back in the limelight. This is because a former air force intelligence official has made claims that the Pentagon is in possession of remains of extraterrestrial craft and “non-human biological matter”. The claims have been backed up by the testimony of a retired navy commander and a former navy pilot.
What we can be certain of is that the more we explore our skies, the more likely it is that we will encounter phenomena that we cannot explain. However, this does not mean that they are extraterrestrial. Past experience has shown us that most of these events can be attributed to optical illusions, spy or weather balloons, space junk, or even satellites that we ourselves have made.
In Spain, UFOs were a hot topic between the 1960s and the 1980s. In this era, everyone knew someone who was convinced that they had seen a UFO. This even reached the point where an exoplanet, called Ummo, was made up. It was populated by a more advanced civilisation than ours who made contact with people on Earth. In the letters these aliens supposedly sent, the ‘Ummites’ explained concepts such as genetics and cell structure.
The truth is that nowadays, reading some of these letters can be quite amusing. The story of the planet of Ummo was ultimately proved to be a monumental hoax, a fact later admitted by its own creator.
The Ummo hoax was even linked to the creation of a paedophile ring, which should make us reflect on the harmful consequences that the spread of fabricated news stories can have.
Can we deny the possibility that intelligent alien civilisations exist?
The answer, of course, is no. The universe is immense, and it is more than likely that circumstances similar to those which led to the appearance of life on Earth have been repeated on other planets. But there is a huge distance (literally and figuratively) between acknowledging the existence of these creatures and considering the possibility that they might have visited us.
Exoplanets, also known as extrasolar planets, are extremely far away, and we are limited by the speed of light which, as proven by Einstein, is the maximum possible speed at which anything can travel. Therefore, the journey to even a “nearby” exoplanet would take thousands of years. Maybe a civilisation more advanced than ours could find a way to do it faster, but not to the point of it being something easy or commonplace.
In any case, if the remains of alien life or spacecraft are stored away somewhere, why are they not being shown to us? Scientists would jump at the chance to analyse this organic matter to find out how it is structured, how it metabolises energy, or what molecules it uses to store genetic information.
Until there is proof, this is not a question of science, but rather, of stories. Stories can be very entertaining, but these kinds of stories do not help us to build a more accurate or helpful view of the world.
