Piaget’s Stages of Cognitive Development

Sensorimotor Stage

Birth—2 years

 A 1-year-old learns about objects by touching, grabbing, and putting them in their mouth. What stage?

Sensorimotor stage (birth—2 years)

Which of the following includes key concepts associated with Piaget’s Sensorimotor Stage?

Behavioral schemata, symbolic schemata, assimilation, and accommodation

Behavioral vs. Symbolic Schemata

A baby is given a new toy and immediately grabs it, touches it, bangs it, and puts it in their mouth to explore it. What does this demonstrate?

Behavioral schema

A 3-year-old uses a block as a pretend phone and says, “Hello?” What does this demonstrate?

Symbolic schema

A baby has learned to bang objects on the floor. When given a new toy, the baby immediately bangs it on the floor. What does this demonstrate?

Assimilation

A baby tries to bang a soft stuffed animal like other objects, but realizes it does not work the same way and changes how they interact with it. What does this demonstrate?

Accommodation

A baby searches for a toy after it is hidden under a blanket. What concept?

Object permanence: knowing an object still exists when out of sight.

What are the main characteristics of the preoperational stage?

2 to 7 years; symbolic thought, language, pretend play, egocentrism, centration, and lack of conservation.

What is the preconceptual period?

Ages 2–4; children develop language and symbolic thought through pretend play and imagination.

(have imaginary friends)

Egocentrism

Talk to themselves, imaginary friends, play house, use language in a safe way without critique. They think everyone sees things the way they see them

What is the intuitive period?

Ages 4–7; children rely heavily on perception and show centration and difficulty with conservation.

Which of the following includes key concepts associated with the Preoperational Stage (2 to 7 years)

Preconceptual Period (2-4) and Intuitive Period (4-7)

Perceptual Centration

The tendency to focus on one noticeable feature of something while ignoring other important features.

ex:

Playdough: A child sees two equal balls of playdough. One is stretched into a long, thin shape. The child says the long piece has more because they focus on its length and ignore its width.

Beaker: The same amount of water is poured from a short, wide beaker into a tall, skinny beaker. The child says the tall beaker has more because they focus on the height of the water and ignore the width of the container.

Conservation

The understanding that the amount or quantity of something stays the same, even when its appearance, shape, or arrangement changes.

Ex: A child understands that the same amount of water remains even when it is poured into a taller, thinner glass.

• Playdough: A child does not understand that the amount of playdough stays the same after its shape changes. They may think the longer piece has more playdough.

• Beaker: A child does not understand that the amount of water stays the same after being poured into a different-shaped container. They may think the taller container has more water.

 A child thinks a taller glass has more juice, even though the same amount was poured into it. What concept?

Centration: focusing on one perceptual feature while ignoring others.

A child understands that the same amount of water remains after it is poured into a differently shaped glass. What ability?

Conservation, mastered during the concrete operational stage.

Concrete Operational Stage

7—11 years; Children transition to applying logical operations and rules, but strictly to concrete events, tangible objects, and visible situations.

Which of the following includes key concepts associated with Concrete Operational Stage

Mental representation (Decentration) and Relational Logic (Reversibility)

Mental representation (Decentration)

The ability to evaluate multiple physical dimensions or situations simultaneously.

Relational Logic (reversibility)

The ability to understand relationships between objects or ideas and mentally reverse an action or process.

A 9-year-old can logically solve problems involving physical objects but struggles with “what if” questions. What stage?

Concrete operational stage (about 7–12 years).

Formal Operational Stage

11 years through adults; the stage when individuals develop the ability to think abstractly, logically, and hypothetically, allowing them to reason about possibilities beyond what they can directly see or experience.

Which of the following includes key concepts associated with Formal Operational Stage

Abstract Thinking and Developing Deductive Reasoning

Abstract Thinking

Pondering complex social, philosophical, and moral concepts like justice and future possibilities beyond concrete reality.

Ex: How would the course of US history be different if a woman was the first president?

Developing Deductive Reasoning

The capacity to consider hypothetical possibilities, systematically test variables one at a time (e.g., Piaget's pendulum problem), and deduce logical conclusions.

Which sequence correctly lists Piaget’s stages?

Sensorimotor → Preoperational → Concrete → Formal

Explain Piaget’s four stages of cognitive development. For each stage, identify the approximate age range and describe one major cognitive ability or characteristic that develops during that stage.

Sensorimotor (birth–2): Learning through senses and motor actions; develops object permanence.

Preoperational (2–7): Develops symbolic thought and language; demonstrates egocentrism, centration, and difficulty with conservation.

Concrete operational (7–12): Develops logical thinking about concrete situations; understands conservation, decentration, and reversibility.

Formal operational (12+): Develops abstract and hypothetical thinking and systematic problem-solving.
