Short answer

Sensorimotor: object permanence. Preoperational: symbolic thinking. Concrete Operational: logical thought. Formal Operational: abstract reasoning.

Step-by-step solution

Sensorimotor Stage

This is the first stage of Piaget’s cognitive development theory, occurring from birth to about 2 years old. The key features include object permanence (understanding that objects continue to exist even when they cannot be seen, heard, or touched) and motor activity without the use of symbols.

Preoperational Stage

This stage spans from about 2 to 7 years old. Key features are the development of language and the ability to think symbolically, but thinking is still egocentric and children have difficulty understanding the perspective of others. They also struggle with the concept of conservation (the understanding that quantity doesn't change even when its shape does).

Concrete Operational Stage

This stage lasts from about 7 to 11 years old. Key features include the beginning of logical or operational thought, meaning children can work things out in their heads rather than through physical manipulation. They understand the concepts of conservation, reversibility, and cause and effect.

Formal Operational Stage

Starting from about age 12 and onwards, this final stage allows individuals to think abstractly and reason about hypothetical problems. They can now use deductive logic and understand the concept of abstract thinking.

Key concepts

Sensorimotor Stage

The Sensorimotor Stage is the first stage in Piaget's theory of cognitive development, spanning from birth to approximately two years old. Babies learn about the world through their senses and motor activities.

Key features of this stage include:

• **Object permanence**: This is the understanding that objects continue to exist even when they are not seen, heard, or touched. For example, if a toy is covered by a blanket, the baby will still know it is there.
• **Motor activity without the use of symbols**: Infants explore their surroundings and understand the environment through physical interaction and movement rather than mental representation. They learn by doing and touching rather than thinking.

This stage is characterized by rapid cognitive growth and significant achievements in understanding the physical world.

Preoperational Stage

The Preoperational Stage occurs between the ages of approximately 2 and 7 years. During this period, children develop the ability to think symbolically and use language to represent objects and experiences.

Key features of this stage include:

• **Symbolic thinking**: Children begin to use words and images to represent objects and ideas. For example, a child may pretend a stick is a sword.
• **Egocentrism**: Thinking is still very self-centered. Children have difficulty seeing things from perspectives other than their own.
• **Conservation issues**: Children struggle with understanding that certain properties of objects remain the same even when their appearance changes (e.g., the quantity of liquid remains the same whether it is in a tall, thin glass or a short, wide one).

This stage is crucial for language development and the growth of imaginative play, yet logical reasoning and perspective-taking remain challenging.

Concrete Operational Stage

The Concrete Operational Stage ranges from approximately 7 to 11 years old. During this time, children start to develop logical or operational thought, meaning they can perform mental operations on tangible objects and events.

Key features of this stage include:

• **Logical thinking**: Children can think logically about concrete events. They are able to solve problems through manipulation in their minds rather than having to manipulate objects physically.
• **Conservation**: Children understand that quantity remains the same despite changes in shape or appearance. For example, they can comprehend that pouring water from a tall glass to a short, wide glass does not change the amount of water.
• **Reversibility**: They grasp the concept that objects or numbers can return to their original state. For instance, if 3 + 2 equals 5, then 5 - 2 equals 3.
• **Cause and effect**: Children understand cause and effect relationships in concrete contexts.

This stage promotes a solid foundation for future abstract thinking skills and deeper reasoning abilities.

Formal Operational Stage

The Formal Operational Stage starts around age 12 and continues into adulthood. This final stage in Piaget's theory is marked by the ability to think abstractly and logically.

Key features of this stage include:

• **Abstract thinking**: Adolescents and adults can think about abstract concepts that do not have physical form, such as love, justice, and freedom.
• **Hypothetical reasoning**: They can consider hypothetical scenarios and reason about potential outcomes. For example, they can imagine and logically discuss what might happen if a certain event occurred.
• **Deductive logic**: Individuals can use a general principle to determine a specific outcome. They develop the ability to form and test hypotheses in a systematic way.
• **Problem-solving skills**: Teens and adults become capable of complex problem-solving and critical thinking. They can evaluate various solutions and decide which one is the best based on logical reasoning.

This stage signifies a significant increase in cognitive abilities, enabling individuals to engage in sophisticated mental processes and philosophical thinking.
