Centration is when a child locks onto one feature of a situation and misses other relevant details. In Intro to Cognitive Science, it shows up in Piaget's account of preoperational thinking and conservation errors.
Centration is a pattern in child cognition where attention gets stuck on one visible dimension of a problem, such as height, length, or color, while other dimensions are pushed out of the decision. In Intro to Cognitive Science, you usually see it in Piaget's explanation of why young children reason differently from older children.
A classic example is conservation. If the same liquid is poured from a short, wide cup into a tall, thin glass, a child showing centration may say the tall glass has more. The child is not ignoring the whole scene on purpose. Instead, the child is mentally over-weighting one cue, usually the most obvious one, and not coordinating it with the fact that nothing was added or removed.
That makes centration more than a simple mistake. It shows a limitation in how multiple features are integrated at once. The child can notice several things in the room, but when a task asks for comparison or transformation, one feature dominates the judgment and the rest get screened out. This is why Piaget linked centration to the preoperational stage, when thinking is still tied closely to what is immediately seen.
You can also spot centration in sorting tasks. If you ask a child to group objects by shape and color at the same time, they may sort only by one category, like color, even when the task calls for noticing both. The answer is not just “wrong,” it reveals how the child is representing the problem.
As children move toward the concrete operational stage, they become better at decentration, which means paying attention to more than one aspect of a situation. At that point, they can compare transformations, reversibility, and quantity more logically. Centration, then, is a useful window into how cognitive limits shape what a child thinks is happening versus what is actually happening.
Centration matters because it explains a whole class of early reasoning errors in Cognitive Science, especially the ones Piaget used to show that children are not just smaller adults with less knowledge. Their thinking is organized differently. When a child focuses on one feature and misses the rest, you can predict mistakes in conservation, classification, and other tasks that require coordination of several cues at once.
This term also gives you a mechanism, not just a label. Instead of saying a child is "confused," centration tells you what the confusion looks like: attention and judgment are stuck on one dimension of the display. That makes it easier to explain why the same child may answer one question correctly in one setup but fail in another setup that hides the same information differently.
In this course, centration connects perception, attention, memory, and reasoning. It is a good example of how cognitive science studies behavior by asking what information a person notices, how it is represented, and how that representation affects the final answer. It also gives you a clean contrast with later, more flexible thinking in the concrete operational stage and beyond.

Centration is one of the clearest signs of preoperational thinking in Piaget's model. Children in this stage often rely on what stands out visually instead of coordinating several properties at once. That is why tasks that seem obvious to an older child, like comparing equal amounts of liquid in different containers, can still produce incorrect answers.
Conservation
Conservation tasks are the classic way centration shows up in class. If a child says the taller glass has more water after a pour, the child is centering on height and ignoring width. So conservation errors are not random, they are a direct result of how the child is attending to the display.
Egocentrism
Egocentrism and centration often appear together in Piagetian explanations, but they are not the same thing. Egocentrism is trouble taking another perspective, while centration is trouble balancing multiple aspects of one situation. A child can be centered on one feature even when no other person's viewpoint is involved.
Piaget's Theory
Centration is one of the main pieces of evidence Piaget used to argue that cognitive development happens in stages. He treated it as a limit of preoperational thought and a sign that logical coordination is still developing. Later stages show less centration because children can compare dimensions, reverse actions mentally, and reason about quantity more reliably.
A quiz question may show two drawings, containers, or sorting sets and ask why a child gives a certain answer. Your job is to name centration and explain which single feature the child fixated on. In a short response, connect that one-sided focus to a conservation error or a sorting mistake. If the prompt asks how thinking changes with age, mention decentration and the move toward concrete operational reasoning.
Egocentrism is about difficulty taking another person's perspective, while centration is about focusing on one feature of a situation and missing other relevant features. They can show up together in Piaget's work, but they describe different limits in thinking. If the question is about perspective-taking, choose egocentrism. If it is about ignoring one dimension, choose centration.
Centration is the tendency to focus on one feature of a situation and ignore other relevant features.
In Intro to Cognitive Science, centration is usually discussed through Piaget's explanation of preoperational thinking.
The clearest example is conservation, where a child may judge the taller container as holding more liquid even when the amount is unchanged.
Centration shows that early mistakes are often about how information is attended to and represented, not just about missing facts.
As children develop decentration, they become better at comparing more than one dimension at the same time.
Centration is when a child zeroes in on one obvious feature of a problem and ignores other relevant information. In cognitive science, it is a Piagetian explanation for why young children often give nonlogical answers on tasks like conservation. The term points to a limit in how multiple cues are coordinated.
Because the child focuses on a single visible dimension, like height or width, and treats that one cue as if it tells the whole story. If the water looks taller in one glass, the child may assume there is more of it, even though the amount stayed the same. The mistake comes from attention, not from the liquid changing.
No. Egocentrism is trouble taking someone else's perspective, while centration is trouble balancing more than one feature of a situation. They often appear in the same stage of development, which makes them easy to mix up. A good shortcut is that egocentrism is about viewpoint, and centration is about features.
Look for an answer that overuses one cue and ignores the rest. If the prompt involves containers, sorting, or visual comparison, the child may be locking onto shape, height, color, or one other obvious property. The best explanation usually mentions that the child is not coordinating multiple dimensions yet.
